Die Erfindung bezieht sich auf Strahldüsen. Insbesondere bezieht sich die Erfindung auf Strahldüsen, die geeignet sind zur Benutzung in Verbindung mit unter Hochdruck stehendem Wasser, um eine Reinigung verschmutzter OberflächenThe invention relates to jet nozzles. In particular, the invention relates to jet nozzles that are suitable are for use in conjunction with high pressure water to clean dirty surfaces

durch Abtragen der Ablagerungen zu bewirken. Eine Anwendung der Düse ist in der gleichzeitig mit vorliegender Anmeldung eingereichten Patentanmeldung der Anmelderin beschrieben, die sich auf die Priorität aus der britischen Patentanmeldung 52 625/76 stützt. Die Düse kann jedoch auch für andere Anwendungen benutzt werden.by removing the deposits. An application of the nozzle is in the simultaneous with the present application patent application filed by the applicant, referring to the priority from the UK Patent application 52 625/76 is based. However, the nozzle can also be used for other applications.

Gemäß einem Merkmal der Erfindung weist eine Strahldüse, welche eine einzige durch den Düsenkopf hindurchgehende Düsenöffnung besitzt, wenigstens zwei Schlitze über dem Düsenkopf auf, die sich in der Öffnung schneiden, damit wenigstens zwei sich schneidende flache fächerförmige Strahlen erzeugt werden können.According to one feature of the invention, a jet nozzle has a single one passing through the nozzle head Nozzle opening has at least two slots above the nozzle head that intersect in the opening so at least two intersecting flat fan-shaped beams can be generated.

Die Schlitze weisen vorzugsweise einen gleichen Winkelabstand zueinander auf, derart, daß die flachen fächerförmigen Strahlen ebenfalls im gleichen Winkelabstand zueinander liegen. Die Düsenöffnung liegt vorzugsweise in der Mitte des Düsenkopfes. Der Durchmesser der Düsenöffnung ist vorzugsweise größer als die Breite eines jeden Schlitzes.The slots are preferably at the same angular spacing to each other in such a way that the flat fan-shaped rays are also at the same angular distance from each other lie. The nozzle opening is preferably in the middle of the nozzle head. The diameter of the nozzle opening is preferably greater than the width of each slot.

Die Schlitze können im Querschnitt U-förmig sein. Die Schlitze können am Boden,im Querschnitt betrachtet, abgeflacht sein. Statt dessen können auch andere Gestaltungen, z. B. V-förmige Schlitze, benutzt werden.The slots can be U-shaped in cross section. The slots can be flattened at the bottom, viewed in cross section be. Instead, other designs, e.g. B. V-shaped slots can be used.

Wenigstens einer der Schlitze kann sich in der Tiefe nachAt least one of the slots can be down in depth

dem Umfang des Düsenkopfes hin vermindern. Statt dessen kann wenigstens einer der Schlitze eine konstante Tiefe über die Länge aufweisen. Wenn sich die Schlitztiefe ändert, dann kann sie sich zweckmäßigerweise in Form eines Kreisbogens, im Querschnitt betrachtet, ändern. Einer oder mehrere der Schlitze können sich kontinuierlich nach dem Umfang des Diisenkopfes hin erstrecken.reduce the circumference of the nozzle head. Instead, at least one of the slots can have a constant depth have over the length. If the slot depth changes, then it can expediently take the form of a Circular arc, viewed in cross section, change. One or more of the slots can move continuously extend towards the circumference of the nozzle head.

Nachstehend wird ein Ausführungsbeispiel der Erfindung an Hand der Zeichnung beschrieben. In der Zeichnung zeigen:An exemplary embodiment of the invention is described below with reference to the drawing. In the drawing show:

Fig. 1 eine perspektivische Ansicht einer Strahldüse,1 is a perspective view of a jet nozzle,

Fig. 2 eine Seitenansicht der Strahldüse nach Fig. 1,FIG. 2 is a side view of the jet nozzle according to FIG. 1,

Fig. 3 eine Stirnansicht der Strahldüse gemäß Fig. 1,3 shows an end view of the jet nozzle according to FIG. 1,

Fig. 4- einen Schnitt nach der Linie IV-IV gemäß Fig. 3.FIG. 4- a section along the line IV-IV according to FIG. 3.

Die dargestellte Strahldüse weist einen zylindrischen Kopf 10 mit einem Mittelabschnitt 11 mit einer sechseckigen Schlüsselfläche auf, deren Umfang größer ist als der Umfang des Kopfes 10, und es ist ein Gewindeabschnitt 12 auf der der Düse gegenüberliegenden Seite des Kopfes 10 angeordnet .The jet nozzle shown has a cylindrical head 10 with a central section 11 with a hexagonal Wrench surface, the circumference of which is larger than the circumference of the head 10, and there is a threaded portion 12 on the side of the head 10 opposite the nozzle.

Der Kopf 10 besitzt eine ebene Stirnfläche mit einer in der Mitte angeordneten Düsenöffnung 17» die längs der Zentralachse des Kopfes 10 verläuft. Die öffnung 17 steht mit einem Kanal 18 in Verbindung, der sich über die länge der Düse erstreckt.The head 10 has a flat end face with a nozzle opening 17 arranged in the middle along the The central axis of the head 10 runs. The opening 17 is standing with a channel 18 in communication, which extends the length of the nozzle.

Zwei senkrecht aufeinanderstellende Schütze 15 bzw. 16 sind in die Stirnfläche des Kopfes 10 derart eingeschnitten, daß sich die Schlitze 15 und 16 in der Öffnung 17 schneiden. Die Schlitze 15 und 16 besitzen eine sich über ihre länge ändernde Tiefe, und jeder Schlitz ist als Kreisbogen im Schnitt gemäß Fig. 4- eingeschnitten, wobei der tiefste Teil des Schlitzes im Bereich der Düsenöffnung 17 liegt. Beide Schlitze sind U-förmig gestaltet und erstrecken sich über vier Fünftel des Durchmessers des Kopfes 10.Two contactors 15 and 16 placed perpendicular to one another are cut into the end face of the head 10 in such a way that the slots 15 and 16 in the opening 17 cut. The slots 15 and 16 have one over their length changing depth, and each slot is cut as a circular arc in the section according to FIG. 4-, wherein the deepest part of the slot lies in the area of the nozzle opening 17. Both slots are U-shaped and extend over four fifths the diameter of the head 10.

Der Gewindeabschnitt 12 wird in eine Gewindebuchse (nicht dargestellt) eingeschraubt, die Hochdruckwasser der Düse liefert. Unter "Hochdruck" werden Drücke zwischen 0,7The threaded section 12 is inserted into a threaded bushing (not shown), which supplies high pressure water to the nozzle.
