Abstract

Eine Hochdruckplungerpumpe, mit mindestens einer Plungeranordnung (1), die einen an eine Ventilsitzsaugleitung (6) und eine Ventilsitzdruckleitung (15) angeschlossenen Arbeitsraum (16) aufweist, in dem ein Plunger (2) axial hin und her bewegbar angeordnet ist, wobei die Ventilsitzdruckleitung (15) durch ein Druckventil (4) und die Ventilsitzsaugleitung (6) durch ein Saugventil (5) verschließbar sind und das Saugventil (5) mittels einer Gegendruckeinrichtung (7) bedarfsweise gesteuert in einer Offenstellung haltbar ist, ist so ausgebildet, dass die Gegendruckeinrichtung (7) eine Zuführleitung (9) aufweist, über die zur Offenhaltung des Saugventils (5) ein Steuerfluid auf das Saugventil (5) führbar ist, wobei an die Zuführleitung (9) zur Druckerzeugung des Steuerfluids eine Niederdruckpumpe (20) angeschlossen ist.
