Description
Inj ektor. Die Erfindung betrifft einen Injektor mit Führung des Rückschlagventiikegels- an dem-' herausnehmbaren Düseneinsatz und besteht darin, daß sich der Rückschlagventilkegel auf der Speisedruckdüse, gegen die er abzudichten hat, buchsenartig führt, wobei der Rückschlagventilkorb den Hub des Rückschlagventilkegels irgendwie begrenzt: und zugleich die Kupplung der Speisedruckdüse mit der Wasserdüse bewirkt. Gleichzeitig erhält der Rückschlagventilkegel eine an seinembuchsenartigen Führungsteil nach. dessen Ende zu angebrachte Verstärkung, die einerseits im geöffneten Zustande gegen den Rückschlagventilkorb zwecks Hubbegrenzung anliegt und< andererseits zugleich ein Ausgleichgewicht gegenüber dem im offenen Zustande überhängenden Kopfgewicht des Rückschlagventilkegels bildet. Die Verstärkung an dem buchsenartigen Rückschlagkegelführungsteil wird zweckmäßig als umlaufender Wulst ausgebildet, der kolbenartig im Rückschlagventilkorb gleitet, so daß bei der dadurch gegebenen doppelten Rückschlagkegelführung, eine auf der Speisedruckdüse und die andere im Rückschlagventilkorb, zugleich eine durch die Doppelführung gesperrte Kammer gebildet ist, die als Bremskammer beim Zugehen des Rückschlagventilkegels wirkt und den Kegelaufschlag mildert.Injector. The invention relates to an injector with guidance of the Rückschlagventiikegels- on the 'removable nozzle insert and consists in that the check valve cone on the feed pressure nozzle, against which it has to seal, leads like a bushing, with the check valve basket somehow limits the stroke of the check valve cone: and at the same time causes the coupling of the feed pressure nozzle with the water nozzle. Simultaneously the check valve cone receives a guide part on its bushing. its end to attached reinforcement, which on the one hand in the open state against the check valve basket is in contact for the purpose of stroke limitation and <on the other hand at the same time a balance weight against the overhanging head weight in the open state of the check valve cone. The reinforcement on the bush-like check cone guide part is expediently designed as a circumferential bead, the piston-like in the check valve cage slides, so that with the double check cone guide given thereby, one on the feed pressure nozzle and the other in the check valve basket, at the same time one through the double guide locked chamber is formed, which acts as a brake chamber when approaching of the check valve cone acts and reduces the cone impact.
In der Zeichnung ist eine Ausführungsform der Erfindung im Schnitt dargestellt. Es bedeutet i den Rückschlagventilkorb, 2 die Speisedruckdüse, 3 den Rückschlagventilkegel, d. die Wasserdüse, 5 die Führungsbuchse, 6 den an dessen Ende angebrachten Wulst, 7 den überhängenden Ventilkopf. 8 ist die durch die Doppelführung des Rückschlagkegels gesperrte Bremskammer, 9 das Injektorgehäuse. io sind Öffnungen im Kegelführungsfeil 5, durch die die geförderte Flüssigkeit in die Druckleitung°ii aus dem Gehäuse entweicht.In the drawing, an embodiment of the invention is in section shown. It means i the check valve basket, 2 the feed pressure nozzle, 3 den Check valve cone, d. the water nozzle, 5 the guide bushing, 6 the at its End attached bead, 7 the overhanging valve head. 8 is the one through the double leadership the non-return cone locked brake chamber, 9 the injector housing. io are openings in the cone guide file 5, through which the pumped liquid in the pressure line ° ii escapes from the housing.
