Abstract
Description
La présente invention se rapporte à un distributeur d'air ou gaz comprimé placé ou non en bout d'un piston de vérin et qui, après son activation, a un fonctionnement automatique provoqué par la pression et la dépression de l'air dans le vérin.The present invention relates to a compressed air or gas distributor placed or not at the end of a cylinder piston and which, after its activation, has a automatic operation caused by pressure and air depression in the cylinder.
La présente invention se rapporte également à une réalisation sous forme de kit ou intégrée à tout ensemble mobile mû par air comprimé ou pression pneumatique (éventuellement gaz sous pression autres que l'air).The present invention also relates to an achievement in kit form or integrated into everything mobile assembly driven by compressed air or pneumatic pressure (possibly pressurized gas other than air).
On connaít déjà de nombreux types de distributeur à air comprimé mais il sont tous actionnés par des moyens mécaniques, électromécaniques ou électroniques sans avoir une possibilité de fermeture et ouverture automatique de l'arrivée d'air comprimé en fonction de la pression/dépression de l'air, ainsi que d'échappement automatique de l'air lors du retour du piston du vérin.We already know many types of compressed air distributor but they are all operated by mechanical, electromechanical or electronic means without having a possibility of closing and opening automatic compressed air supply depending on the air pressure / vacuum, as well as exhaust automatic air movement when the cylinder piston returns.
Le domaine technique de prédilection d'utilisation de tels dispositifs est bien entendu celui de l'armement et en particulier celui des armes à air comprimé. Ainsi, généralement, l'air comprimé par un moyen mécanique mis en oeuvre par l'opérateur au moment du chargement (pompage à main), ou encore un gaz comprimé, tel que le dioxyde de carbone, contenu dans une cartouche, est distribué d'une chambre de stockage vers le canon de l'arme. Cette distribution se fait au moyen d'une soupape actionnable par pression sur la détente.The technical field of choice of use of such devices is of course that of armaments and in particular that of air weapons compressed. So, generally, compressed air by a means mechanical implemented by the operator at the time of charging (hand pumping), or a compressed gas, such as that the carbon dioxide in a cartridge is distributed from a storage chamber to the barrel of tear. This distribution is done by means of a valve actuated by pressing the trigger.
Par exemple, le brevet américain US-A-5 400 536 décrit un pistolet à barillet rotatif et à double action, présentant un vérin en ligne avec le canon pour le tir de projectiles. Au moment du tir, une tige solidaire du piston du vérin est percutée par le chien, ce qui ouvre la soupape et libère un gaz sous pression dans le canon.For example, US patent US-A-5,400 536 describes a rotary and double barrel pistol action, presenting a cylinder in line with the barrel for the projectile fire. When firing, a rod secured to the piston of the cylinder is struck by the dog, which opens the valve and releases pressurized gas into the barrel.
Le brevet américain US-A-5 613 483 divulgue l'assemblage d'un piston et d'un cylindre pour une arme à gaz. Le piston peut se déplacer d'arrière en avant, entre une position de chargement et une position de tir. Le cylindre présente deux chambres au travers desquelles se meut le piston. Lorsque le piston est en position de chargement, le cylindre est en communication via la première chambre avec un dispositif de fourniture de gaz sous pression. Cette position du piston empêche toute communication entre les deux chambres. Par contre, en position de tir, il n'y a plus communication entre la première chambre et la fourniture de gaz mais bien communication entre les deux chambres, ce qui permet au gaz de passer de la première dans la deuxième chambre. Pour ce faire, la tige de piston est munie d'une section de passage au niveau du contact avec le cylindre qui s'étend de manière longitudinale.U.S. Patent US-A-5,613,483 discloses assembling a piston and a cylinder for a handgun gas. The piston can move back and forth, between a loading position and a firing position. The cylinder has two chambers through which moves the piston. When the piston is in the position of loading, the cylinder is in communication via the first chamber with a gas supply device under pressure. This position of the piston prevents any communication between the two rooms. However, in firing position, there is no longer any communication between the first bedroom and gas supply but fine communication between the two chambers, allowing gas to move from the first to the second bedroom. For this do, the piston rod is provided with a passage section at the contact with the cylinder which extends from longitudinally.
Enfin, le document US-A-5 363 834 décrit une arme possédant un premier mode de fonctionnement pour la propulsion d'un projectile par gaz comprimé contenu dans une cartouche et un second mode de fonctionnement pour la propulsion par air comprimé généré par un mécanisme de pompage manuel. Le but poursuivi est de pouvoir remédier à une panne du système de fourniture de gaz comprimé (dioxyde de carbone). Un switch manuel actionnable par le tireur permet de passer d'un mode de fonctionnement à l'autre, en mettant en contact une chambre de stockage soit avec le gaz comprimé, soit avec l'air comprimé obtenu par pompage. Lors du tir, le chien percute un élément de piston de vérin qui libère l'air ou le gaz sous pression vers le canon de l'arme.Finally, document US-A-5,363,834 describes a weapon having a first operating mode for the propulsion of a projectile by compressed gas contained in a cartridge and a second operating mode for compressed air propulsion generated by a manual pumping. The aim is to be able to remedy a failure of the compressed gas supply system (dioxide of carbon). A manual switch operable by the shooter allows switching from one operating mode to another, by bringing a storage chamber into contact with either the gas compressed, or with the compressed air obtained by pumping. then from the shot, the dog strikes a cylinder piston element which releases pressurized air or gas to the barrel tear.
Aucun des distributeurs d'air comprimé de l'état de la technique mentionnés ci-dessus ne présente un mode de fonctionnement automatique. En outre, ces dispositifs très complexes ne sont pas compatibles avec l'aménagement d'un distributeur se présentant sous forme de kit. Or, dans le cas de l'armement par exemple, on souhaite de plus en plus procéder à des simulations fonctionnelles, c'est-à-dire dépourvues d'envoi d'un projectile, mais reproduisant fidèlement toutes les fonctions normales de l'arme comme le mouvement des pièces mobiles et le recul associé, les efforts sur la détente, etc. De telles simulations font appel par exemple à l'envoi d'un rayon laser sur une cible. Le rayon laser peut être déclenché par un contacteur électrique percuté par un piston de soupape.None of the compressed air distributors the above-mentioned prior art does not present a automatic operating mode. In addition, these very complex devices are not compatible with the layout of a distributor in the form of kit. However, in the case of armaments for example, we wish more and more carry out functional simulations, that is to say without sending a projectile, but faithfully reproducing all the normal functions of the weapon like the movement of moving parts and recoil associated, efforts on relaxation, etc. Such simulations use for example the sending of a ray laser on a target. The laser beam can be triggered by an electrical contactor struck by a valve piston.
Il y a donc un intérêt potentiel pour développer un système de vérin automatique.So there is potential interest in develop an automatic cylinder system.
La présente invention vise à fournir un vérin et son distributeur de gaz comprimé, de préférence en ligne, à fonctionnement complètement automatique après activation grâce à une impulsion initiale.The present invention aims to provide a jack and its compressed gas distributor, preferably in line, fully automatic after activation by an initial impulse.
L'invention a pour but complémentaire de pouvoir fournir, pour certaines applications, un tel vérin et son distributeur sous forme de kit, aisément adaptable sur des équipements existants. The invention has the complementary aim of ability to provide, for certain applications, such a cylinder and its distributor in kit form, easily adaptable on existing equipment.
L'invention a également pour but de fournir un tel distributeur qui soit compact, c'est-à-dire causant une très faible augmentation de la longueur du vérin par intégration du distributeur, simple et facile de réalisation.The invention also aims to provide such a distributor which is compact, that is to say causing a very small increase in the length of the cylinder by distributor integration, simple and easy to production.
Enfin, l'invention vise à proposer un distributeur pneumatique automatique utilisable dans un grand nombre de domaines techniques et non limité au secteur spécifique de l'armement.Finally, the invention aims to propose a pneumatic automatic distributor usable in a large number of technical fields and not limited to specific armaments sector.
La présente invention se rapporte à un dispositif à fonctionnement automatique pour la distribution de gaz comprimé, par exemple de l'air ou du dioxyde de carbone comprimé, comprenant un vérin constitué d'un cylindre dans lequel peut coulisser un piston muni d'une tête de piston, ledit cylindre étant muni à une extrémité avant obturable, dite support de distributeur, d'un distributeur se trouvant dans le prolongement dudit vérin. Le distributeur peut être commandé directement par l'avant du piston.The present invention relates to a automatic device for the distribution of compressed gas, for example air or compressed carbon dioxide, comprising a cylinder constituted a cylinder in which can slide a piston provided a piston head, said cylinder being provided with a closable front end, called distributor support, a distributor located in the extension of said cylinder. The dispenser can be ordered directly by the front of the piston.
Le distributeur présente une arrivée de gaz comprimé, une chambre pouvant contenir ledit gaz sous pression étant dynamiquement située entre l'extrémité obturable du cylindre et la tête de piston.The distributor has a gas supply compressed, a chamber that can contain said gas under pressure being dynamically located between the end lockable cylinder and piston head.
Le dispositif de l'invention est caractérisé en ce qu'il comprend des moyens pour effectuer successivement et automatiquement les opérations suivantes, après que le piston ait été percuté initialement du côté de son extrémité arrière par un marteau :
- déplacement du piston vers l'avant, admission de gaz comprimé dans la chambre et pressurisation de celle-ci,
- recul du piston vers l'arrière, échappement du gaz comprimé contenu dans la chambre et dépressurisation de celle-ci,
- retour du piston vers l'avant, fermeture de l'arrivée de gaz comprimé, échappement vers l'avant du gaz résiduel contenu dans la chambre et retour du dispositif à sa position initiale.
- displacement of the piston forwards, admission of compressed gas into the chamber and pressurization of the latter,
- backward movement of the piston, exhaust of the compressed gas contained in the chamber and depressurization of the latter,
- return of the piston forwards, closing of the compressed gas supply, exhaust of the residual gas contained in the chamber towards the front and return of the device to its initial position.
Selon une modalité d'exécution préférée de l'invention, le dispositif comprend une soupape capable de s'ouvrir et se fermer selon l'axe du cylindre et un joint double permettant l'ouverture et la fermeture de l'arrivée de gaz comprimé, la soupape étant munie d'un ressort de rappel tel qu'à l'équilibre, elle soit décollée du joint double, côté arrière, le joint double étant muni d'un ressort de rappel tel qu'à l'équilibre, il obture l'arrivée de gaz comprimé.According to a preferred embodiment of the invention, the device comprises a valve capable of open and close along the cylinder axis and a seal double allowing the opening and closing of the arrival of compressed gas, the valve being provided with a spring reminder such that at equilibrium, it is detached from the joint double, rear side, the double seal being provided with a return spring such that at equilibrium, it closes the arrival compressed gas.
Avantageusement, la tête du piston peut entrer en contact à l'avant du cylindre avec la soupape, ce qui provoque le recul solidaire de ladite soupape et du joint double à butée contre le support de distributeur, ce qui provoque l'admission par une arrivée de gaz comprimé dans la chambre.Advantageously, the piston head can come into contact at the front of the cylinder with the valve, this which causes the integral recoil of said valve and the double seal with stop against the distributor support, this which causes admission by a compressed gas supply in the bedroom.
Selon l'invention, lors de la dépressurisation de la chambre par retour du piston vers l'arrière, le gaz sous pression s'échappe soit par sortie du piston hors du cylindre, soit par un orifice aménagé dans le cylindre, le piston restant alors à l'intérieur du cylindre.According to the invention, during the depressurization of the chamber by return of the piston towards rear, pressurized gas escapes either through outlet of the piston out of the cylinder, either through a fitted orifice in the cylinder, the piston then remaining inside the cylinder.
De préférence, le piston est muni d'un ressort de rappel qui a tendance à le ramener vers sa position d'équilibre à l'avant du cylindre.Preferably, the piston is provided with a return spring which tends to bring it back towards its equilibrium position at the front of the cylinder.
Toujours selon l'invention, la chambre n'étant pas ou étant faiblement pressurisée et le piston n'étant plus en contact avec la soupape, la soupape et le joint double sont dans leur position d'équilibre sous l'effet de leurs ressorts de rappel respectifs et la soupape est décollée du joint double, ce qui permet un échappement de gaz contenu dans la chambre au travers d'un orifice pourvu dans la paroi du support de distributeur, le joint double étant en position de fermeture de l'arrivée de gaz sous pression.Still according to the invention, the bedroom not being or being weakly pressurized and the piston no longer in contact with the valve, the valve and the double seal are in their equilibrium position under the effect of their respective return springs and the valve is detached from the double seal, allowing a exhaust of gas contained in the chamber through a orifice provided in the wall of the distributor support, the double seal being in the closed position of the arrival of gas under pressure.
Selon une modalité d'exécution de l'invention, le contact entre le piston et la soupape est réalisé au moyen d'un percuteur de commande capable de coulisser librement à l'intérieur du piston, la partie arrière du percuteur ayant été percutée initialement par le marteau.According to an execution modality of the invention, the contact between the piston and the valve is produced by means of a control striker capable of slide freely inside the piston, the part rear of the striker having been struck initially by the hammer.
Selon encore une modalité d'exécution alternative de l'invention, le distributeur peut être commandé par un dispositif de traction placé devant l'ensemble constitué par le distributeur et son vérin. Dans ce cas, le dispositif de traction remplace la percussion initiale du piston par un marteau.According to another method of execution alternative of the invention, the dispenser can be controlled by a traction device placed in front the assembly constituted by the distributor and its cylinder. In in this case, the traction device replaces the percussion initial piston with a hammer.
Le fait de présenter un ensemble très compact permet de diminuer fortement les pertes d'air comprimé dues à la distance entre le distributeur et le vérin.The fact of presenting a very compact set greatly reduces the compressed air losses due at the distance between the distributor and the cylinder.
Un autre avantage réside dans le fait de pouvoir réarmer très facilement l'élément d'activation (marteau) du distributeur par le recul du piston.Another advantage is that ability to easily reset activation element (hammer) of the distributor by the recoil of the piston.
Le dispositif vérin/distributeur de la présente invention est utilisable avantageusement avec des armes à fonctionnement de type pistolet (avec glissière) ou fusil (avec culasse mobile).The cylinder / distributor device of the present invention is advantageously usable with pistol-type weapons (with slide) or rifle (with movable breech).
La présente invention sera décrite à l'aide des figures annexées représentant un éclaté accompagné de sa nomenclature, ainsi que le positionnement des pièces en fonction des différentes étapes du principe de base de fonctionnement, ce principe pouvant par ailleurs être adapté en fonction des besoins des utilisateurs.The present invention will be described using appended figures representing an exploded view accompanied by its nomenclature, as well as the positioning of the pieces in function of the different stages of the basic principle of this principle can also be adapted according to user needs.

Le dispositif de distribution de l'air
comprimé automatique selon l'invention peut être réalisé
sous forme de kit ou intégré dans tout mécanisme tel que
fusil ou pistolet notamment pour la simulation de tir ou
dans tout mécanisme en fonction des possibilités
d'exploitation des avantages de l'invention. L'activation
initiale du distributeur est obtenue par percussion d'un
percuteur 9 pouvant coulisser librement à l'intérieur d'un
piston 80, au moyen d'un marteau (ou chien) 15 qui peut
être une pièce d'origine d'une arme ou du dispositif équipé
du distributeur automatique d'air comprimé selon
l'invention. La percussion se fait par pivotement vers
l'avant du marteau 15 dans un évidement du corps de piston

automatic tablet according to the invention can be produced
in kit form or integrated into any mechanism such as
rifle or pistol especially for shooting simulation or
in any mechanism depending on the possibilities
exploitation of the advantages of the invention. activation
initial of the dispenser is obtained by percussion of a
Dans la position de repos ou position
initiale (figure 2), l'arrivée d'air comprimé à partir d'un
système d'alimentation quelconque, par le raccord 14, est
obturée par le joint double circulaire de distribution 3.In the rest position or position
initial (figure 2), the arrival of compressed air from a
any supply system, via
La figure 3 représente la position
d'ouverture de l'arrivée d'air. Dans la forme d'exécution
décrite, on a donc pris l'exemple d'une commande par
l'intermédiaire d'un percuteur 9 qui passe au travers du
piston 80 du vérin et est commandé par un marteau 15 qui
vient frapper ledit percuteur 9. Ce dernier transmet son
déplacement linéaire à la soupape 5 du distributeur. La
soupape 5 vient alors en contact avec le joint de
distributeur 3, ce dernier se déplaçant vers la gauche, ce
qui permet à l'air comprimé de passer entre l'ensemble
accolé joint 3 - soupape 5 et la tête de piston 11 du
vérin. Figure 3 shows the position
opening the air supply. In the form of execution
described, so we took the example of a command by
through a
L'entrée de l'air comprimé dans le cylindre 1
a pour effet de maintenir, par la pression de l'air qui y
est comprimé, l'ensemble 3,5 en position à butée gauche
contre le support de distributeur 2, l'arrivée d'air 14
restant ouverte et également pour effet le recul solidaire
des différentes pièces 8,9,10,11 composant le piston 80 du
vérin vers la droite (figure 4).The entry of compressed air into
La figure 5 représente la position de
dépressurisation dans le vérin. Lors du recul du piston 80
du vérin, ce dernier peut, soit sortir du tube vérin ou
cylindre 1, soit rester dans le cylindre grâce à un
échappement d'air latéral 12 se trouvant dans le tube vérin
1. Dans les deux cas, cela a pour effet de faire chuter la
pression dans le tube vérin 1 et, par la même occasion, de
diminuer la pression sur l'ensemble joint de distributeur 3
et soupape 5. L'ensemble 3,5 peut alors, sous l'effet des
ressorts respectifs 4,6 des deux pièces 3,5 reprendre sa
position initiale vers la droite (figure 6), ce qui obture
l'arrivée d'air comprimé grâce au joint double circulaire
du distributeur 3. Cela permet également l'échappement de
l'air se trouvant encore dans la chambre 10 lors du retour
du piston 80 du vérin qui, mû par son ressort (non
représenté) retourne dans sa position initiale de repos
vers la gauche. L'échappement de l'air, lors de ce retour,
est réalisé grâce au décollement de la soupape 5 du joint
de distributeur 3, par le trou inférieur 20 du support du
distributeur 2 (voir vue de détail de la figure 6).
L'arrivée d'air comprimé reste obturée à ce stade et le
système est revenu à sa position initiale de repos. La
séquence complète des mouvements du vérin et du
distributeur est donc réalisée automatiquement puisqu'elle
est initiée uniquement par l'impulsion du marteau 15, sans
que soit nécessaire une quelconque autre intervention. Figure 5 shows the position of
depressurization in the cylinder. When the
Le système ayant un critère d'universalité, il est bien évident que la forme d'exécution relative aux figures ci-dessus est donnée à titre d'illustration et d'exemple et que le principe peut être adapté suivant les besoins de l'utilisateur.The system having a criterion of universality, it is obvious that the form of execution relating to above figures is given for illustration and example and that the principle can be adapted according to user needs.
Par exemple, la partie percuteur 9 pourrait
être absente et être remplacée par un contact direct entre
le piston 80 du vérin et la soupape 5, ce qui aurait pour
effet que, lors de la fermeture du vérin vers la gauche, on
aurait automatiquement à disposition toutes les fonctions
illustrées aux figures 3 à 6. Pour arrêter, dans cette
configuration, le cycle de fonctionnement, il suffit
d'interrompre le piston du tube vérin avant son contact
avec la soupape 5.For example, the
Le dispositif de l'invention peut être réalisé sous forme de kit à monter directement dans des armes de simulation de tir ou être adaptable à tout autre mécanisme, soit en kit, soit intégré à un ensemble plus complexe, requérant ou non des modifications du dispositif d'origine.The device of the invention can be produced as a kit to be mounted directly in fire simulation weapons or be adaptable to any other mechanism, either as a kit, or integrated into a more complex, whether or not requiring modifications to the system original.
Le vérin/distributeur de l'invention présente notamment les avantages suivants :
- grande compacité vu la très faible augmentation de la longueur du vérin par l'intégration du distributeur ;
- fonction ouverture de l'arrivée d'air avec maintien pendant toute la durée du déplacement du piston vers l'arrière ;
- fonction fermeture automatique de l'arrivée d'air comprimé par dépression de chambre ;
- fonction échappement de l'air automatique lors du retour de piston ;
- possibilité de réalisation sous forme de kit ;
- réarmement automatique du marteau ;
- possibilité de déplacement de pièces mobiles, non exclusivement limité à des fins d'alimentation pneumatique dans des armes à gaz ou air comprimé.
- great compactness given the very small increase in the length of the cylinder by the integration of the distributor;
- function of opening the air intake with maintenance for the entire duration of the rearward displacement of the piston;
- automatic closing function of the compressed air supply by chamber vacuum;
- automatic air exhaust function when the piston returns;
- possibility of realization in kit form;
- automatic resetting of the hammer;
- possibility of moving moving parts, not exclusively limited to pneumatic supply in gas or compressed air weapons.
L'homme de métier pourra aisément adapter la mise en oeuvre du dispositif de l'invention aux spécificités d'un produit donné tout en gardant les mêmes principes de fonctionnement.Those skilled in the art can easily adapt the implementation of the device of the invention with specific features of a given product while keeping the same principles of operation.
