Abstract: A pump housing accommodates in it an output shaft of an electromotor which forms a unit with the pump, and a rotor having substantially slots is mounted on the output shaft for rotation. The slots accommodate sliding vanes. A mounting member mounts the rotor on the output shaft in such a manner that the motor can tilt to a limited extent about two axes which are normal to each other and to the longitudinal axis of the output shaft of the electromotor.
