Abstract

Die Erfindung bezieht sich auf eine Radialkolbenpumpeneinheit zur Kraftstoff-Hochdruckversorgung bei Kraftstoff-Einspritzsystemen, insbesondere bei Common-Rail-Hochdruck-Einspritzsystemen, mit einem Pumpengehäuse (1), in welchem eine Antriebswelle (21) mit mindestens einem Exzenterabschnitt (31) gelagert ist, mit einem Exzenterring (15), welcher mindestens eine Betätigungsscheibe (10) eines in einem Zylinder (2) gelagerten Verdichterkolbens (4) beaufschlagt, mit einem, einen Teil des Zylinders (2) umgebenden Stützelement, welches durch mindestens eine Feder (11) belastet ist und mit einem mit dem Verdichterkolben (4) zusammenwirkenden Saug- und einem Druckventil (6, 7). Erfindungsgemäß sind auf der Antriebswelle (21) im Bereich des Exzenterabschnitts (31) zwei Seitenscheiben (17, 17') mit Polygonflächen gelagert, welche als Mitnahmemechanismus für den Exzenterring (15) dienen.,
