Abstract

Eine Kolbenpumpe, insbesondere eine Reihen- oder Radialkolbenpumpe zur Kraftstoffhochdruckerzeugung bei Common-Rail-Einspritzsystemen, weist eine in einem Pumpengehäuse (1) drehbar gelagerte Nockenwelle (2) auf, die mindestens einen Exzenternocken (3) aufweist. Dem Exzenternocken (3) ist mindestens ein Pumpenkolben (4, 14) zugeordnet, der vom Exzenternocken (3) betätigt ist und der in etwa radialer Richtung zur Nockenwelle (2) eine Hubbewegung (5) ausführen kann. Die Hubbewegung (5) umfaßt einen zur Nockenwelle (2) gerichteten Abwärtshub (5') und einen entgegengesetzt gerichteten Aufwärtshub (5''). Zur Reduzierung des Verschleißes der Kolbenpumpe ist vorgesehen, daß zwischen jedem Pumpenkolben (4, 14) und dem Exzenternocken (3) ein Pleuelelement (6, 16, 26, 36, 46) angeordnet ist, welches durch Abwälzen die Hubbewegung (5) und die Kraft auf den Pumpenkolben (4, 14) überträgt.
