| 摘要 |
The invention relates to a rotary piston pump, comprising a pump housing having a pump chamber, an inlet opening, an outlet opening, a first, multi-vane rotary piston, which is arranged in the pump chamber and is rotatably supported about a first axis, a second, multi-vane rotary piston arranged in the pump chamber, which is rotatably supported about a second axis that is spaced from the first axis and which meshes with the first rotary piston, wherein the first and second rotary pistons produce a fluid flow from the inlet opening to the outlet opening by rotating about the first and second axes, respectively, and a drive device, which is mechanically coupled to the rotary pistons in order to drive the rotary pistons. According to the invention, the drive device comprises a first electric drive motor, which is mechanically coupled to the first rotary piston in order to drive the first rotary piston, and a second electric drive motor, which is mechanically coupled to the second rotary piston in order to drive the second rotary piston. |
