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.

Abstract: Electrical machine (12) for a drive train (10) of a motor vehicle, having a housing section (34), having a stator (36) which is fixed in relation to the housing section (34) and has a stator core (40) to which the stator windings (38) are fixed, having a rotor (42) which is mounted such that it can rotate in relation to the stator (36), and having a stator cooling arrangement (50) for cooling the stator (36), wherein the stator cooling arrangement (50) has at least one cooling channel (52) which extends along a circumferential section of the stator (36) and through which a cooling fluid can be routed in a flow direction (54). In this case, a plurality of turbulence-generating elements (64) are arranged in the cooling channel (52), said turbulence-generating elements being arranged one behind the other in the flow direction (54) and/or offset in a manner in transverse to the flow direction (54) in the cooling channel (52), wherein at least some turbulence-generating elements (64) are formed by turbulence-generating projections (68; 70), of which at least one is integrally formed with the housing section (34) and/or of which at least one is integrally formed with the stator core (40), and wherein at least one of the turbulence-generating projections (68; 70) has a radial length which is equal to at least 70% of the radial depth of the cooling channel (52).
