Pump units are known that have a drive shaft and a rotor, which is driven by the drive shaft and is arranged rotatably in a housing, the drive shaft having an oblique sliding plane, which interacts with the rotor and allows the rotor to nutate with the rotor axis thereof about a drive axis of the drive shaft, the rotor having a set of teeth on the end face of the rotor facing away from the drive shaft, said teeth meshing with a set of teeth formed on a housing of the pump unit, working spaces being formed between the teeth of the rotor and the teeth of the housing, which working spaces can be filled via an inlet and emptied via an outlet. It is disadvantageous that the pump unit has a comparatively large axial installation length, because the drive of the pump unit is arranged on an end of the drive shaft facing away from the rotor. In the pump unit according to the invention, the axial installation length is shortened. According to the invention the drive shaft () is surrounded by a stator () and magnets () are provided on the drive shaft (), which magnets interact magnetically with the stator ().

The invention relates to a rotary piston engine () which operates as a pump, condenser or motor for a liquid or gaseous medium. The rotary piston engine () has a first gear () having a first central axis (I), a second gear () arranged opposite the first gear () and having a second central axis (II), and a drive shaft () having a third central axis (III) and a sliding plane () fixedly connected to the drive shaft (). The first central axis (I) and the second central axis (II) enclose an angle (&#x3b1;) which is not equal to 180&#xb0;. The third central axis (III) and at least one central axis (I, II) from the group comprising the first central axis (I) and second central axis (II) enclose an angle (&#x3b1;) which is not equal to 0&#xb0; or 90&#xb0;. The sliding plane () and the central axis (I, II) are perpendicular to each other. The first gear () has a first end face () having a first has toothing () that h at least one first tooth (), and the second gear () has a second end face () having a second toothing () that has at least one second tooth (), wherein a first number of first teeth and a second number of second teeth differ from each other. The first tooth () and the second tooth () engage with each other in such a way that a working chamber () is formed by means of a meshing of the teeth (). A volume formed by means of the at least one working chamber () is changed by the meshing of the teeth (). The at least one working chamber () is delimited by a conically shaped inner wall () of a housing (). The at least one working chamber () can be connected to a supply flow () and an outlet flow () for the medium. According to the invention, a component () from the group comprising the first gear () and second gear () is coupled to the housing () such that a rotation of the drive shaft () causes only the components () to tumble. The respective other components () from the group comprising the first gear () and second gear () is coupled to the sliding plane () such that the respective other component () rotates and tumbles by means of a rotation of the drive shaft ().

A feed unit comprising a first toothing part () and a second toothing part () which interact with one another via a toothing system () and axes () of which are set obliquely with respect to one another, the first toothing part () engaging around the second toothing part () with a collar section (), and working spaces () being formed between the toothing system () of the first toothing part () and the toothing system () of the second toothing part (), which working spaces () are configured to be filled via an inflow () and are configured to be emptied via an outflow ().

Feed unit

A media delivery assembly in which a defined compensating pressure is established at the backs of included axially adjustable rotors and a control valve is provided for establishing the compensating pressure at a predetermined value between a pressure on the pressure side and a pressure on the suction side.
