Abstract
Die Erfindung betrifft eine Einzylinder-Hochdruckpumpe zur Hochdruckversorgung in Common-Rail-Einspritzsystemen von Brennkraftmaschinen, mit einem in einem Pumpengehäuse (1) aufgenommenen Pumpenelement, das einen Pumpenkolben (5) umfasst, der in einem Pumpenzylinder (4) gegen die Vorspannkraft einer Druckfeder (7) hin und her bewegbar aufgenommen und durch einen Nocken (8) angetrieben ist, um mit Hochdruck beaufschlagten Kraftstoff in ein Rail zu fördern.The invention relates to a single-cylinder high-pressure pump for High pressure supply in common rail injection systems from Internal combustion engines, with one in a pump housing (1) picked up pump element, which has a pump piston (5) comprises the in a pump cylinder (4) against the Preload force of a compression spring (7) can be moved back and forth picked up and driven by a cam (8) high-pressure fuel into a rail promote.
Um die Lebensdauer der Einzylinder-Hochdruckpumpe zu verlängern, ist auf der vom Nockenantrieb (8) abgewandten Seite in dem Pumpengehäuse (1) eine Montageöffnung (3) zur Aufnahme des Pumpenelements vorgesehen. In order to extend the life of the single-cylinder high-pressure pump, an assembly opening (3) for receiving the pump element is provided in the pump housing (1) on the side facing away from the cam drive (8).
