Description

Dispositif de bouchage pour un réservoir ou une enceinte.Clogging device for a tank or enclosure.
L'invention concerne un dispositif de bouchage pour un réservoir, en particulier mais non exclusivement un réservoir d'huile sous pression, ou une enceinte du type comprenant un opercule de fixation sur l'ouverture d'une tubulure débouchant dans le réservoir et un joint d'étanchéité appliqué sous pression entre l'opercule et un épaulement de ladite tubulure, ainsi qu'un organe de verrouillage tel qu'un levier articulé sur ledit opercule pour assurer son verrouillage en position de fermeture sur l'opercule ainsi que la compression dudit joint d'étanchéité.The invention relates to a closure device for a reservoir, in particular but not exclusively a pressurized oil reservoir, or an enclosure of the type comprising a sealing cap on the opening of a tube opening into the reservoir and a seal. seal applied under pressure between the cover and a shoulder of said tube, as well as a locking member such as a lever articulated on said cover to ensure its locking in the closed position on the cover as well as the compression of said seal.
De tels bouchons sont en particulier utilisés dans le domaine des réservoirs d'huile sous pression et doivent permettre une ouverture facile pour le remplissage ou le complément de remplissage du réservoir, tout en facilitant une fermeture simple, éventuellement avec un positionnement précis, et en garantissant une fermeture et une étanchéité sûres.Such caps are in particular used in the field of pressurized oil tanks and must allow easy opening for filling or additional filling of the tank, while facilitating simple closing, possibly with precise positioning, and guaranteeing secure closing and sealing.
Le demandeur fabrique depuis de nombreuses années un bouchon du type décrit à l'introduction, destiné en particulier aux moteurs et réacteurs d'avions dans lequel un levier monté pivotant sur l'opercule agit, par l'intermédiaire d'une bille. sur une pièce d'étanchéité en deux parties séparées par un ressort de compression, l'une des pièces comportant un joint d'étanchéité appuyé sur un épaulement de la tubulure. L'opercule est auparavant fixé sur la tubulure par un système à baïonnette. Le bouchon peut rester solidaire à la tubulure par une chaînette. Cet ensemble, d'une efficacité et d'une fiabilité éprouvées, présente cependant en premier lieu l'inconvénient d'une construction et d'un montage relativement compliqués, onéreux et d'un encombrement important.The applicant has been manufacturing for many years a plug of the type described in the introduction, intended in particular for aircraft engines and reactors in which a lever pivotally mounted on the cover acts, by means of a ball. on a seal piece in two parts separated by a compression spring, one of the pieces comprising a seal pressed against a shoulder of the tube. The cover is previously fixed to the tubing by a bayonet system. The plug can remain attached to the tubing by a chain. This assembly, of proven efficiency and reliability, however first of all has the drawback of a relatively complicated, expensive construction and assembly and a large bulk.
On connaît également, par US-A-4.366.669, un bouchon du type précédent destiné aux réacteurs aéronautiques dans lequel l'opercule est articulé sur la tubulure et le joint d'étanchéité est disposé à la périphérie de l'opercule, de sorte qu'il est comprimé après serrage du levier. Le levier agit sur une tige portant un joint par l'intermédiaire d'un ressort. Cette construction est également compliquée et onéreuse et, en outre, la sécurité de fixation n'est pas suffisante, en particulier en régime vibratoire de longue durée et de fréquence variable comme c'est le cas à bord d'un avion.Also known from US-A-4,366,669 is a plug of the previous type intended for aeronautical reactors in which the cover is articulated on the pipe and the seal is placed at the periphery of the cover, so that it is compressed after tightening the lever. The lever acts on a rod carrying a seal by means of a spring. This construction is also complicated and expensive and, moreover, the safety of attachment is not sufficient, in particular in vibratory regime of long duration and variable frequency as is the case on board an aircraft.
La présente invention vise en conséquence à fournir un bouchon du type décrit à l'introduction qui ne présente pas les inconvénients des bouchons connus.The present invention therefore aims to provide a plug of the type described in the introduction which does not have the drawbacks of known plugs.
A cet effet, le bouchon selon l'invention est caractérisé en ce qu'au moins un coulisseau est monté sensiblement radialement dans l'opercule et peut être déplacé longitudinalement vers l'extérieur de l'opercule, contre l'action de moyens élastiques, sous l'effet de la fermeture dudit organe de verrouillage, l'extrémité externe dudit coulisseau comportant un biseau formé par exemple par un chanfrein tronconique, coopérant avec un biseau de même inclinaison aménagé en regard du coulisseau, en position de fermeture de l'opercule, dans la paroi interne de la tubulure.To this end, the plug according to the invention is characterized in that at least one slide is mounted substantially radially in the cover and can be moved longitudinally towards the outside of the cover, against the action of elastic means, under the effect of the closure of said locking member, the outer end of said slide comprising a bevel formed for example by a frustoconical chamfer, cooperating with a bevel of the same inclination arranged opposite the slide, in the closed position of the cover , in the internal wall of the tubing.
La fermeture du levier assure ainsi simultanément la compression du joint d'étanchéité et le verrouillage de 1'opercule ou bouchon sur la tubulure.Closing the lever thus simultaneously ensures the compression of the seal and locking of the seal or plug on the tubing.
Dans de nombreuses applications, on prévoit que la tubulure est démontable et forme une embase.In many applications, it is expected that the tubing is removable and forms a base.
Selon une forme de réalisation de l'invention, un poussoir, en particulier une bille, est intercalé entre une came du levier et l'extrémité du coulisseau opposée audit biseau. Dans ce cas, de préférence, l'axe de rotation du levier est légèrement décalé vers l'extrémité libre du levier par rapport à l'axe de déplacement du poussoir, de manière à renforcer la sécurité du verrouillage.According to one embodiment of the invention, a pusher, in particular a ball, is interposed between a cam of the lever and the end of the slide opposite to said bevel. In this case, preferably, the axis of rotation of the lever is slightly offset towards the free end of the lever relative to the axis of movement of the pusher, so as to reinforce the security of the locking.
Selon une forme de réalisation préférée de l'invention, l'opercule comprend au moins deux coulisseaux montés non symétriques par rapport à un plan diamétral de l'opercule, les extrémités externes desdits coulisseaux faisant légèrement saillie à l'extérieur de l'opercule en position d'ouverture du levier, le biseau de la tubulure adjoint à chaque coulisseau étant formé par un évidement d'axe incliné par rapport à l'axe de la tubulure et à distance du bord libre de la tubulure, ledit évidement étant relié audit bord de la tubulure respectivement par une rainure comportant au moins une section non axiale. De cette manière, l'extrémité saillante de chaque coulisseau doit coopérer pour le montage, avec la rainure avant d'arriver en regard de l'alésage adjoint, par une rotation du type baïonnette, avec un prépositionnement formant détrompeur à cause de la dissymétrie des coulisseaux. Si les têtes des coulisseaux sont tronconiques, on forme ainsi un moyen pour assurer 1'actionnement successif des coulisseaux au cours de la fermeture du levier du fait de la non-symétrie des coulisseaux.According to a preferred embodiment of the invention, the cover comprises at least two slides mounted non-symmetrical with respect to a diametrical plane of the cover, the external ends of said slides projecting slightly outside the cover in lever open position, the bevel of the tubing attached to each slide being formed by a recess with an axis inclined relative to the axis of the tubing and at a distance from the free edge of the tubing, said recess being connected to said edge of the tubing respectively by a groove having at least one non-axial section. In this way, the projecting end of each slide must cooperate for mounting, with the groove before arriving opposite the adjoining bore, by a bayonet type rotation, with a prepositioning forming a key because of the asymmetry of the slides. If the heads of the slides are frustoconical, a means is thus formed to ensure the successive actuation of the slides during the closing of the lever due to the non-symmetry of the slides.
Selon une forme d'exécution de l'invention, la tubulure comporte une gorge périphérique interne dans laquelle peut s'encliqueter une bague déformable élastiquement, de préférence fendue, formant une extrémité de plus grand diamètre d'une crépine en forme de panier tronconique. On obtient ainsi un montage simple d'une crépine très économique.According to one embodiment of the invention, the tubing has an internal peripheral groove in which can be snapped an elastically deformable ring, preferably split, forming an end of larger diameter of a tapered basket strainer. A simple assembly of a very economical strainer is thus obtained.
Avantageusement, un tube est ménagé d'une seule pièce dans la paroi intérieure de la tubulure pour le passage d'une tige. Cette tige permet, de manière connue, d'agir sur une membrane décrite plus loin afin de ménager un passage d'air lors du remplissage. Avantageusement, ledit tube comporte une encoche de fixation d'un anneau d'extrémité d'une chaînette ou d'un câble dont l'autre extrémité est reliée, directement ou indirectement, à la face intérieure dudit opercule.Advantageously, a tube is formed in one piece in the inner wall of the tube for the passage of a rod. This rod allows, in known manner, to act on a membrane described below in order to provide an air passage during filling. Advantageously, said tube comprises a notch for fixing an end ring of a chain or of a cable, the other end of which is connected, directly or indirectly, to the internal face of said cover.
Dans le cas le plus général d'une tubulure démontable, il est avantageux de prévoir que l'extrémité de la tubulure opposée à l'opercule est fermée par un fond muni d'ouvertures de passage et une membrane élastique est appliquée extérieurement contre lesdites ouvertures. Cette membrane est avantageusement formée par une rondelle elastiquement deformable fixée audit fond dans une partie pleine, de préférence par encliquetage sur une rainure d'une saillie dudit fond.In the most general case of a removable tube, it is advantageous to provide that the end of the tube opposite the cover is closed by a bottom provided with passage openings and an elastic membrane is applied externally against said openings. . This membrane is advantageously formed by an elastically deformable washer fixed to said bottom in a solid part, preferably by snap-fastening on a groove of a projection of said bottom.
L'invention sera bien comprise à la lecture de la description suivante, faite en référence au dessin annexé, d'un ensemble de bouchage selon un exemple de réalisation de l'invention. Dans ce dessin :The invention will be clearly understood on reading the following description, made with reference to the appended drawing, of a closure assembly according to an exemplary embodiment of the invention.

la figure 5 est une vue de dessus de la crépine de la figure 4.FIG. 5 is a top view of the strainer of FIG. 4.
L'ensemble selon l'exemple de réalisation représenté est constitué par une tubulure ou embase 1 fermée à une extrémité par une opercule ou bouchon 2, l'extrémité opposée de la tubulure 1 étant fermée par un fond 3 muni d'orifices périphériques 4 et d'une saillie centrale externe 5. La tubulure 1 peut être fixée sur l'encolure d'un réservoir (non représenté) contenant par exemple de l'huile de lubrification d'un réacteur d'avion.The assembly according to the illustrated embodiment is constituted by a tube or base 1 closed at one end by a cover or plug 2, the opposite end of the tube 1 being closed by a bottom 3 provided with peripheral orifices 4 and an external central projection 5. The tubing 1 can be fixed on the neck of a tank (not shown) containing for example lubricating oil from an aircraft reactor.
La face de 1'opercule 2 tournée vers la tubulure 1 comporte un bord biseauté muni d'une gorge annulaire dans laquelle est logé un joint torique compressible 7. Le bord biseauté de l'opercule 2 coopère avec un épaulement 6 de même inclinaison que la tubulure 1, au cours du déplacement axial de l'opercule 2.The face of the cover 2 facing the tube 1 has a beveled edge provided with an annular groove in which is housed a compressible O-ring 7. The beveled edge of the cover 2 cooperates with a shoulder 6 of the same inclination as the tubing 1, during the axial movement of the cover 2.
Ce déplacement axial est produit par le pivotement d'un levier 8 autour d'un axe 9 monté sur l'opercule 2. La face du levier 8 adjacente à l'opercule 2 comporte un profil de came 10 coopérant avec une bille 11 montée coulissante dans une cheminée axiale 12 de l'opercule 2. Trois alésages radiaux ou sensiblement radiaux 13 ménagés dans l'opercule 2 communiquent avec la cheminée 12 et sont ouverts à leur extrémité périphérique externe. Dans chaque alésage 13 est logé un coulisseau 14, rappelé vers le centre par un ressort 15, dont 1'extrémité conique interne 16 est en saillie en regard du débouché de la cheminée 12. L'extrémité opposée des coulisseaux 14 comporte un chanfrein tronconique 17 faisant saillie partiellement de la périphérie de l'opercule 2 lorsque le levier 8 est relevé (position de déverrouillage) .This axial movement is produced by the pivoting of a lever 8 around an axis 9 mounted on the cover 2. The face of the lever 8 adjacent to the cover 2 has a cam profile 10 cooperating with a ball 11 mounted to slide in an axial chimney 12 of the lid 2. Three radial or substantially radial bores 13 formed in the lid 2 communicate with the chimney 12 and are open at their external peripheral end. In each bore 13 is housed a slide 14, returned towards the center by a spring 15, the internal conical end 16 of which projects opposite the outlet of the chimney 12. The opposite end of the slides 14 has a frustoconical chamfer 17 partially projecting from the periphery of the cover 2 when the lever 8 is raised (unlocking position).
Les trois alésages 13 sont disposés avec leurs axes A, B, C radiaux formant respectivement entre eux des angles X, Y, Z (figure 3) non égaux à 120° de sorte que les coulisseaux 14 sont, dans cette position de relevage du levier 8, en appui dissymétrique les uns contre les autres par leurs chanfreins tronconiques 16. Il s'ensuit que les distances respectives a, b, c des faces frontales des coulisseaux 14 à l'axe de la cheminée 12 sont différentes et que la bille 11 entre successivement en contact, au cours de sa descente, avec le chanfrein 16 le plus proche (distance c), puis avec le chanfrein 16 à la distance b et enfin avec le chanfrein 16 à la distance c. Il s'ensuit que les trois coulisseaux 14 sont repoussés successivement par la bille 11, ce qui est favorable à une garantie de bonne fixation du bouchon et à la progressivité de l'effort appliqué sur le levier 8.The three bores 13 are arranged with their radial axes A, B, C respectively forming angles X, Y, Z (FIG. 3) not equal to 120 ° so that the slides 14 are, in this position for raising the lever 8, asymmetrically supported against each other by their frustoconical chamfers 16. It follows that the respective distances a, b, c of the end faces of the slides 14 at the axis of the chimney 12 are different and that the ball 11 successively comes into contact, during its descent, with the nearest chamfer 16 (distance c), then with the chamfer 16 at distance b and finally with chamfer 16 at distance c. It follows that the three slides 14 are pushed back successively by the ball 11, which is favorable to a guarantee of good fixing of the stopper and to the progressiveness of the force applied to the lever 8.
En outre, de préférence et en contradiction avec la représentation de la figure 1, l'axe de rotation 9 est légèrement décalé vers l'extrémité du levier 8 par rapport au profil de came 10, de sorte que le levier 8 est ainsi assuré contre une ouverture involontaire, y compris sous l'effet de vibrations.In addition, preferably and in contradiction with the representation of FIG. 1, the axis of rotation 9 is slightly offset towards the end of the lever 8 relative to the cam profile 10, so that the lever 8 is thus secured against involuntary opening, even under the effect of vibrations.

Les chanfreins tronconiques 17 des coulisseaux 14 coopèrent, en position de verrouillage (figure 1), avec des biseaux formés, dans la paroi interne de la tubulure 1 , par des alésages inclinés 18 ayant la pente des biseaux 17, de sorte que le coulissement radial vers l'extérieur des coulisseaux 14 sous 1'action de la bille 11 provoque une descente supplémentaire de l'opercule 2 qui comprime le joint torique 7 en position d'étanchéité, simultanément au verrouillage de l'opercule.The frustoconical chamfers 17 of the slides 14 cooperate, in the locked position (FIG. 1), with bevels formed, in the internal wall of the pipe 1, by inclined bores 18 having the slope of the bevels 17, so that the radial sliding towards the outside of the slides 14 under the action of the ball 11 causes an additional descent of the cover 2 which compresses the O-ring 7 in the sealing position, simultaneously with the locking of the cover.
Les alésages 18 sont répartis angulairement comme les alésages 13 de 1'opercule 2 mais peuvent être remplacés par une gorge continue ou discontinue.The bores 18 are angularly distributed like the bores 13 of the cover 2 but can be replaced by a continuous or discontinuous groove.
Une rainure ménagée dans 1'intérieur de la tubulure 1 débouche respectivement dans chaque alésage 18 (ou à l'emplacement angulaire correspondant de la rainure continue) et comporte une section axiale 19 (figure 2) débouchant à l'extrémité de la tubulure 1 et prolongée par une section circonf ?ntielle 20 débouchant dans l'alésage 18 respectif (ou à l'emplacement correspondant de la rainure continue) .A groove made in the interior of the pipe 1 opens respectively into each bore 18 (or at the corresponding angular location of the continuous groove) and comprises an axial section 19 (Figure 2) opening ext r Emite of the tubing 1 and extended by a circumference section? ntielle 20 opening into the respective bore 18 (or the corresponding location of the continuous groove).
La fermeture du dispositif nécessite donc de placer préalablement chacune des extrémités saillantes 17 des coulisseaux 14 en regard de la section 19 appropriée, ce qui constitue un système de détrompage pour la mise en place du bouchon. On fait ensuite subir au bouchon 2 une translation puis une rotation (système à baïonnette) jusqu'à ce que les extrémités 17 des coulisseaux 14 viennent buter respectivement contre le bord de l'alésage 18. Dans cette position, et seulement dans cette position, le levier 18 peut être abaissé pour permettre l'introduction des extrémités 17 dans les alésages 18, avec l'effet de coulissement du bouchon 2 et de compression du joint 7 expliqué ci-dessus. On assure ainsi un verrouillage ferme du bouchon 2 qui ne peut être supprimé que par une action volontaire sur le levier 8.Closing the device therefore requires placing each of the projecting ends 17 of the slides 14 beforehand opposite the appropriate section 19, which constitutes a keying system for the establishment of the plug. The plug 2 is then subjected to a translation and then to a rotation (bayonet system) until the ends 17 of the slides 14 abut respectively against the edge of the bore 18. In this position, and only in this position, the lever 18 can be lowered to allow the introduction of the ends 17 into the bores 18, with the effect of sliding the plug 2 and compressing the seal 7 explained above. This ensures firm locking of the plug 2 which can only be removed by voluntary action on the lever 8.
A l'ouverture du levier 8, le coulissement en sens inverse du bouchon 2, sous l'action de décompression du joint 7, assure une pré-ouverture libérant un espace annulaire entre le bouchon 2 et la tubulure 1, ce qui permet d'effectuer une mise à l'air libre du réservoir sans risquer une éjection du bouchon 2 du fait de la pression régnant dans le réservoir.At the opening of the lever 8, the sliding in the opposite direction of the plug 2, under the decompression action of the seal 7, provides a pre-opening freeing an annular space between the plug 2 and the tube 1, which allows vent the tank without risking ejection of the plug 2 due to the pressure prevailing in the tank.
La partie supérieure de la tubulure 1 forme une coupelle de remplissage dont la hauteur est sensiblement égale à la hauteur du bouchon 2, de sorte que le liquide en surplus s'écoule au-dessus du bord de la coupelle qui assure ainsi une fonction de trop-plein.The upper part of the tubing 1 forms a filling cup, the height of which is substantially equal to the height of the plug 2, so that the excess liquid flows over the edge of the cup which thus performs an excess function. -full.
Dans la forme de réalisation représentée, la face inférieure du bouchon 2 porte un téton de fixation 20 auquel peut être rattachée une jauge 21. Dans une fente de la jauge 21 (ou directement au téton 20 lorsque la jauge n'existe pas) est relié un anneau 22 monté à une extrémité d'une chaînette 23 ou d'un câble ou similaire.In the embodiment shown, the underside of the plug 2 carries a fixing stud 20 to which a gauge 21 can be attached. In a slot of the gauge 21 (or directly to the stud 20 when the gauge does not exist) is connected a ring 22 mounted at one end of a chain 23 or a cable or the like.
La tubulure 1 est munie d'un tube, latéral 24 qui est avantageusement d'une seule pièce avec cette tubulure 1. Le tube 24 comporte à son extrémité supérieure une encoche 25 à travers laquelle passe un anneau 26 fixé à l'autre extrémité de la chaînette 23 qui solidarise ainsi le bouchon 2 à 1'embase 1.The tubing 1 is provided with a lateral tube 24 which is advantageously in one piece with this tubing 1. The tube 24 has at its upper end a notch 25 through which passes a ring 26 fixed to the other end of the chain 23 which thus secures the plug 2 to the base 1.
En outre, la paroi interne de la tubulure 1 comporte une gorge périphérique 27 traversant le tube 24 et servant au logement d'une bague deformable 28 (figures 4 et 5), par exemple fendue, formant le bord de plus grand diamètre d'une crépine tronconique 29 dont l'extrémité de petit diamètre s'appuie contre le fond 5 de 1'embase 1. On obtient ainsi une crépine de fabrication économique et de montage simplifié. Dans le cas d'une absence de jauge, la hauteur de cette embase 1 peut être considérablement réduite, de sorte que la jonction de la gorge 27 avec le tube 24 peut avantageusement être utilisée pour la fixation de l'anneau 25.In addition, the internal wall of the tube 1 has a peripheral groove 27 passing through the tube 24 and serving to house a deformable ring 28 (FIGS. 4 and 5), for example split, forming the edge of larger diameter of a frustoconical strainer 29, the small diameter end of which rests against the bottom 5 of the base 1. A strainer of economical manufacture and simplified assembly is thus obtained. In the case of an absence of gauge, the height of this base 1 can be considerably reduced, so that the junction of the groove 27 with the tube 24 can advantageously be used for fixing the ring 25.
Grâce à la disposition du fond 3 avec les orifices périphériques 4, dont l'un prolonge le tube 24, il est possible de disposer une membrane élastique de sécurité 30, connue en soi, par simple encliquetage sur une rainure que comporte la saillie 5 du fond 3. Cette membrane 30 vient obturer les orifices 4 sous l'effet de la pression dans le réservoir et interdit ainsi la sortie du liquide qu'il contient. Cette membrane s'abaisse sous le poids du liquide lors du remplissage.Thanks to the arrangement of the bottom 3 with the peripheral orifices 4, one of which extends the tube 24, it is possible to have an elastic safety membrane 30, known per se, by simple snap-fastening on a groove which the projection 5 of the bottom 3. This membrane 30 closes the orifices 4 under the effect of the pressure in the reservoir and thus prevents the exit of the liquid which it contains. This membrane lowers under the weight of the liquid during filling.
Le dispositif de bouchage selon l'invention offre des avantages considérables sur le plan de la fabrication, du poids, de la sécurité, de sorte que, avec au moins les caractéristiques principales de l'invention, il peut être utilisé dans de nombreuses applications aussi variées que les réservoirs de véhicules (huile, combustible et fluide), les portes étanches, les couvercles tels que ceux d'autocuiseurs. etc .The closure device according to the invention offers considerable advantages in terms of manufacturing, weight and safety, so that, with at least the main characteristics of the invention, it can also be used in numerous applications. as varied as vehicle tanks (oil, fuel and fluid), watertight doors, covers such as those for pressure cookers. etc.
Les moyens décrits dans l'exemple de. réalisation précédent peuvent bien entendu être remplacés par des moyens équivalents. C'est ainsi que l'action sur les coulisseaux 14 peut être exercée par d'autres moyens que le levier 8, par exemple par un vérin ou une motorisation. De même, la bille 11 peut, selon le cas, être remplacée par d'autres moyens de transformation du mouvement du levier 8, par exemple un système pignon-vis.The means described in the example of. previous embodiment can of course be replaced by equivalent means. Thus the action on the slides 14 can be exerted by other means than the lever 8, for example by a jack or a motorization. Similarly, the ball 11 can, as the case may be, be replaced by other means for transforming the movement of the lever 8, for example a pinion-screw system.
Une grande précision des composants n'est pas nécessaire du fait de leur mode de coopération. A high precision of the components is not necessary because of their mode of cooperation.
