Abstract

Die Pumpeneinheit (10) umfasst ein Pumpengehäuse (15) mit einem Niederdruckeingang (17) und einem Hochdruckausgang (19). Über den Niederdruckeingang (17) wird einem in dem Pumpengehäuse (15) ausgebildeten Arbeitsraum (20) ein Arbeitsmedium zugeführt. Über den Hochdruckausgang (19) wird das Arbeitsmedium aus dem Arbeitsraum (20) abgeleitet. Des Weiteren umfasst die Pumpeneinheit (10) einen in dem Pumpengehäuse (15) ausgebildeten Pumpkolbenkanal (36) mit einer Längsachse (L1). Die Pumpeneinheit (10) weist einen ersten Pumpkolben (32) auf, der in dem Pumpkolbenkanal (36) entlang der Längsachse (L1) beweglich angeordnet ist und der hydraulisch gekoppelt ist mit dem Arbeitsraum (20). Ferner weist die Pumpeneinheit (10) einen zweiten Pumpkolben (32) auf, der in dem Pumpkolbenkanal (36) entlang der Längsachse (L1) beweglich angeordnet ist und der über ein Ausgleichsvolumen (100) hydraulisch gekoppelt ist mit dem ersten Pumpkolben ( 32 ), wobei das Ausgleichsvolumen (100) hydraulisch gekoppelt ist mit einer Ausgleichseinheit (110), die ausgebildet ist, abhängig von einem Druck in dem Arbeitsraum (20) das Ausgleichsvolumen (100) anzupassen.
