PUMP FOR A FLUID OR GASEOUS MEDIUM

A pump is proposed, in particular a vane pump, for a liquid or gaseous medium, which can be driven with the help of a motor, in particular an electric motor, and which comprises a rotor (15) that can be coupled to a drive shaft (29) of the motor and is arranged in an operating chamber and at least o...

Beschreibung
Zusammenfassung:	A pump is proposed, in particular a vane pump, for a liquid or gaseous medium, which can be driven with the help of a motor, in particular an electric motor, and which comprises a rotor (15) that can be coupled to a drive shaft (29) of the motor and is arranged in an operating chamber and at least one pressure plate (25) that closes the operating chamber (11) in the axial direction and on its lateral face (27) facing away from the rotor (15) is connected to a pressure chamber (23), and also a coupling element (47; 47') which surrounds part of the drive shaft (29), cooperates with at least one seal and contributes to sealing off the pressure chamber (23) with respect to the motor, the drive shaft (29) extending through a through opening (35) in the pressure plate (25). The pump (1) is characterized in that the coupling element (47; 47') has a sleeve-like section (49) which engages in the through opening (35) in the pressure plate (25).
