摘要:
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 (1) is surrounded by a stator (15) and magnets (16) are provided on the drive shaft (1), which magnets interact magnetically with the stator (15).

The invention is based on a rotary piston machine which operates as a pump, a compressor or a motor and which has a rotor (2) and a counterpart rotor (4), wherein the counterpart rotor (4) is arranged opposite the rotor (2). The rotor (2) has a first end surface (6) with a first toothing (8). The counterpart rotor (4) has a second end surface (14) with a second toothing (16). The first toothing (8) and the second toothing (16) are formed in each case from at least one tooth (10, 18) and one tooth space (12, 20). The toothings (8, 16) are in engagement with one another such that first working chambers (22) are formed as a result of meshing of the teeth (10) of the first toothing (8) and the teeth (18) of the second toothing (16), wherein volumes formed by the first working chambers (22) are changed by the meshing of the teeth (10, 18). The rotor (2) has a first axis of rotation (I). The counterpart rotor (4) has a second axis of rotation (II). The first axis of rotation (I) and the second axis of rotation (II) enclose an angle (φ) which is not equal to 0 degrees. According to the invention, the first end surface (6) of the rotor (2) has a third toothing (24) which is spatially separate from the first toothing (8). The second end surface (14) of the counterpart rotor (4) has a fourth toothing (30) which is spatially separate from the second toothing (16). The third toothing (24) and the fourth toothing (30) are formed in each case from at least one tooth (26, 32) and one tooth space (28, 34). The third toothing (24) and the fourth toothing (30) are in engagement with one another such that second working chambers (36) are formed as a result of meshing of the teeth (26) of the third toothing (24) and the teeth (32) of the fourth toothing (30), wherein volumes formed by the second working chambers (36) are changed by the meshing of the teeth (26, 32).

There are already known pump units comprising a drive shaft (2) and a rotatably arranged rotor (3) that is driven by the drive shaft (2), wherein the drive shaft (2) has an inclined sliding surface (4) on an end side, which permits the rotor (3) to move back and forth by its rotor axis (5) about a drive axis (6) of the drive shaft (2), wherein the drive shaft (2) has a first bearing section (18) facing towards the the rotor (3), and a second bearing section (19) facing away from the rotor (3). The first bearing section (18) of the drive shaft (2) is arranged in a first sliding bearing (20), and the second bearing section (19) is arranged in a second sliding bearing (21). The load-bearing capacity of the sliding bearing facing towards the rotor (3) is limited up to a predetermined working pressure in the pump unit. In the pump unit according to the invention, the load-bearing capacity of the sliding bearing (20) facing towards the rotor (3) is increased. According to the invention, the diameter of the first bearing section (18) of the drive shaft (2) and the first sliding bearing (20) is respectively larger than the diameter of the second bearing section (19) and the second sliding bearing (21).
