Abstract

Die Erfindung betrifft eine Radialkolbenpumpe mit Exzentertrieb zur Kraftstoffhochdruckversorgung bei Kraftstoffeinspritzsystemen von Brennkraftmaschinen. Bei derartigen Pumpen besteht das Problem, dass die Kraft, die bei der Kompression des Kraftstoffes an der antriebswellenfernen Oberseite eines Kolbens (10i) entsteht, mehr oder weniger ungleichmäßig auf den Kolbenfuß (20i) und dessen antriebswellenseitige, direkt oder indirekt mit dem Exzenter zusammenwirkende, Kolbenfußfläche (38i) verteilt wird. Um die Belastung des Kolbenfußes (20i) und die damit verbundene Gefahr eines Materialversagens sowie den durch die Zusammenwirkung des Kolbenfußes (20i) mit dem Exzenter bedingten Verschleiß zu verringern, ist erfindungsgemäß eine besondere Gestaltung des antriebswellenseitigen Kolbenendes bzw. des Kolbenfußes (20i) vorgesehen. Mit der Erfindung wird die im Bereich des Kolbenendes bzw. des Kolbenfußes (20i) zur Verfügung stehende Querschnittsfläche für eine vergleichmäßigte Kraftübertragung besser ausgenutzt.
