Abstract
A device for transporting a liquid, in particular a gerotor pump. The device has a housing with a flange which enclose a volume, an outer rotor mounted for rotation about a longitudinal axis and an inner rotor of a displacement mechanism, and a rotor of an electric drive. The rotor of the electric drive is formed integrally with the outer rotor. In addition, the flange is formed integrally with an eccenter for receiving the inner rotor and with a peg-shaped bearing element extending in the direction of the longitudinal axis for receiving the outer rotor.
Claims14
A device for transporting a liquid comprising:
- a housing with a flange which enclose a volume,
- an outer rotor mounted for rotation about a longitudinal axis and an inner rotor of a displacement mechanism, and
- a rotor of an electric drive which is integrally formed with the outer rotor, wherein the flange is integrally formed with an eccenter for receiving the inner rotor and a pin-shaped bearing element extending in a direction of the longitudinal axis for receiving the outer rotor, wherein the bearing element is formed at least substantially cylinder-shaped with a constant outer diameter in the direction of the longitudinal axis, wherein a fluidic connection of a device for pressure equalization is formed between a motor space as a region of the volume enclosed by the housing with the flange and a suction region, wherein the flange has a flattened region in a region of the eccenter, wherein the flattened region is formed on an outer lateral surface, and wherein a first flattened region is formed extending in an axial direction over a full length of the eccenter, starting from a first, free end face to a second end face of the eccenter.
