An electric machine arrangement for a motor vehicle drivetrain, having a machine housing which can be fixed to a drivetrain housing, a stator which is fixed relative to the machine housing, a rotor which is mounted, concentrically with respect to the stator, within the machine housing and which has a rotor axis, wherein an air gap is defined between the stator and the rotor. Here, the rotor has a rotary bearing section which is mounted, with a radial clearance, rotatably relative to a housing bearing section of the machine housing, wherein the radial clearance is smaller than the air gap.

Electric machine arrangement, motor vehicle gearbox and method for producing an electric machine arrangement

An internal-gear pump has a housing which has a first fluid port and a second fluid port. An inner rotor is mounted in the housing so as to be rotatable about an inner rotor axis and has an external toothing. An outer rotor is rotatable in the housing about an outer rotor axis and has an internal toothing which, to generate a pump action, engages with the external toothing of the inner rotor. The internal-gear pump furthermore has a ring element which is mounted movably in the housing so as to be pivotable between a first position and a second position. At least a third fluid port is formed on the housing. The third fluid port is arranged relative to the ring element such that, in the first position of the ring element, the third fluid port is connected to the second fluid port. In the second position, said third fluid port is separated from the second fluid port.
