Abstract

Die Erfindung betrifft eine Pumpe, insbesondere Kraftstoffhochdruckpumpe einer Brennkraftmaschine, aufweisend einen von einem Pumpenzylinderkopf (1) abgedeckten Pumpenzylinder (2), in dem ein Pumpenplunger (3) translatorisch auf und ab bewegbar ist, wobei der Pumpenplunger (3) zusammen mit dem Pumpenzylinderkopf (1) einen Pumpenarbeitsraum (4) begrenzt, der über ein Einlassventil (5) mit einem Niederdruckanschluss und einem Auslassventil (6) mit einem Hochdruckanschluss verbunden ist, und wobei das Einlassventil (5) und das Auslassventil (6) axial zueinander angeordnet sind, Erfindungsgemäß wird eine Pumpe mit einem Einlassventil (5) und einem Auslassventil (6) bereitgestellt, die ein gutes Schließverhalten aufweisen. Erreicht wird dies dadurch, dass das Einlassventil (5) und das Auslassventil (6) einen geführten Ventilkörper (15, 15a) aufweisen.
