Abstract

Die Erfindung betrifft eine Fluidpumpe, insbesondere Hochdruck-Kraftstoffpumpe für Einspritzsysteme von Brennkraftmaschinen, mit wenigstens einem Pumpkolben (10a), der zur Hin- und Herbewegung in Richtung einer Pumpkolbenachse (A) in einem Pumpzylinder (12a) geführt ist, und mit einem hülsenförmigen Stützkörper (14a), der an einer Außenumfangsfläche des Pumpzylinders (12a) in Richtung der Pumpkolbenachse (A) geführt ist und in Mitnahmeverbindung mit dem Pumpkolben (10a) steht. Erfindungsgemäß ist zur Schaffung einer besonders einfachen und dennoch zuverlässigen Mitnahmeverbindung vorgesehen, dass der Pumpkolben (10a) einen einstückig mit dem Pumpkolben ausgebildeten, verbreiterten Pumpkolbenfuß (30a) aufweist und die Mitnahmeverbindung durch einen Sicherungsring (36a) realisiert ist, der teilweise in einer Außenumfangsnut des Pumpkolbenfußes (30a) und teilweise in einer Innenumfangsnut des hülsenförmigen Stützkörpers (14a) angeordnet ist.
