Abstract (en)
[origin: DE19952605A1] A pump, in particular a vane cell pump, for a fluid or gaseous medium, is disclosed. Said pump may be driven by means of a motor, in particular an electric motor and comprises a rotor (15) arranged in an operating chamber, which may be coupled to a motor driveshaft (29) and at least one pressure plate (25), which defines the operating chamber (11) in the axial direction and which, on the lateral face (27) thereof, facing away from the rotor (15), is linked to a pressure chamber (23) as well as a coupling element (47; 47'). Said coupling element (47; 47') contributes to sealing the pressure chamber (23), in cooperation with at least one seal from the motor, whereby the driveshaft (29) extends through an opening (35) in the pressure plate (25). The pump (1) is further characterised, whereby the coupling element (47, 47') comprises a sleeve shaped section (49), which engages in the opening (35) of the pressure plate (25).
