Abstract

Die Erfindung betrifft eine Radialkolbenpumpe (1) mit einem Gehäuse (2), in dem eine Pumpenwelle (3) mit einem Exzenterabschnitt oder wenigstens einer nockenförmigen Erhebung drehbar gelagert ist, und mit wenigstens einem Pumpenkolben (20, 21), der in einem Pumpenzylinder (7, 17) hin- und herbewegbar angeordnet ist. Das Pumpengehäuse und der Pumpenzylinder sind dabei einstückig miteinander ausgebildet. Die Radialkolbenpumpe eignet sich insbesondere zur Kraftstoffhochdruckerzeugung in modernen Common-Rail-Einspritzsystemen.The invention relates to a radial piston pump (1) having a housing (2) in which a pump shaft (3) is rotatably mounted with an eccentric section or at least one cam-shaped elevation, and with at least one pump piston (20, 21) housed in a pump cylinder ( 7, 17) is arranged reciprocable. The pump housing and the pump cylinder are integrally formed with each other. The radial piston pump is particularly suitable for high-pressure fuel production in modern common-rail injection systems.
