Abstract

Innenzahnradpumpe (10), insbesondere für einen Hydraulikkreis (74) eines Kraftfahrzeugantriebsstranges (60), mit einem Gehäuse (12), das einen ersten Fluidanschluss (22) und einen zweiten Fluidanschluss (24) aufweist, einem Innenrotor (14), der in dem Gehäuse (12) um eine Innenrotorachse (32) drehbar gelagert ist und eine Außenverzahnung aufweist, und einem Außenrotor (16), der in dem Gehäuse (12) um einen Außenrotorachse (36) drehbar ist und eine Innenverzahnung aufweist, die zur Erzielung einer Pumpwirkung mit der Außenverzahnung des Innenrotors (14) in Eingriff steht.
Dabei weist die Innenzahnradpumpe (10) ferner ein Ringelement (20) auf, das in dem Gehäuse (12) beweglich gelagert ist und zwischen einer ersten Position (DP1) und einer zweiten Position (DP2) verschwenkbar ist, wobei an dem Gehäuse (12) wenigstens ein dritter Fluidanschluss (26) ausgebildet ist, wobei der dritte Fluidanschluss (26) in Bezug auf das Ringelement (20) so angeordnet ist, dass der dritte Fluidanschluss (26) in der ersten Position (DP1) des Ringelementes (20) mit dem zweiten Fluidanschluss (24) verbunden ist und in der zweiten Position (DP2) von dem zweiten Fluidanschluss (24) getrennt ist (Fig. 1).
