Abstract

Eine Fluidpumpe (20), insbesondere eine Kraftstoff-Hochdruckpumpe, umfasst ein Gehäuse (50) und mindestens einen einlassseitigen Niederdruckanschluss (18). Ferner ist ein Einlassventil (40) und ein Förderraum (32) vorhanden, der von einem Förderelement (30) begrenzt wird. Es wird vorgeschlagen, dass die Fluidpumpe (20) einen Druckdämpfer (48) umfasst, der einlassseitige Druckschwankungen dämpft und der mindestens ein kompressibles Volumen (76) umfasst, welches unmittelbar im Strömungsweg (46) zwischen Niederdruckanschluss (18) und Einlassventil (40) angeordnet ist.
