Abstract

The invention relates to an internal-gear pump (10), in particular for a hydraulic circuit (160) of a motor vehicle power train (140), said pump comprising: a housing (12); an internal rotor (14), mounted in the housing (12) to rotate about an internal rotor axis (32) and having external teeth; an external rotor (16), mounted in the housing (12) to rotate about an external rotor axis (36) and having internal teeth which engage with the external teeth of the internal rotor (14) in order to achieve the pumping action; and a ring element (20) which can be pivoted in the housing (12) between a first position (A) and a second position (B). The pivoting action of the ring element (20) between the first position (A) and the second position (B) is supported in at least one direction in that the internal rotor (14) and the external rotor (16) can be blocked against one another, at least in one part of the whole pivoting range.
