Title:
PENDULUM-SLIDE CELL PUMP
Document Type and Number:
WIPO Patent Application WO/2012/052240
Kind Code:
A3
Abstract:
The invention relates to a pendulum-slide cell pump (1), in particular for supplying an internal combustion engine with lubricant, for example with oil, having a rotationally mounted internal rotor (2) which is connected to an external rotor (4) via pendulum slides (3). It is essential to the invention here that a stator (5) is arranged outside the external rotor (4), and that the external rotor (4) and the stator (5) are constituent parts of an electric drive device for driving the pendulum-slide cell pump (1). As a result, the delivery rate of the pendulum-slide cell pump (1) can be influenced via current feed to the drive device and/or via an eccentricity of the internal rotor (2).
