摘要： The invention relates to a method for producing wear resisting coated surfaces. The inventive method uses at least two electrodes which are connected to a voltage source and which are introduced into or abut against a reaction chamber. An electrolyte flows through said reaction chamber and the surface to be coated is located therein. The method is characterized in that the direction of flow of the electrolyte is reversed at least once during the coating process.

摘要： 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).

摘要： A vane-cell pump has a rotor that receives a plurality of radially movable vanes, a lifting ring which surrounds the rotor and forms at least one suction and one pressure region, and at least one compression plate which forms a lateral delimiting surface of the suction and pressure regions. When the vane-cell pump is in operation, a pressure is applied to the side of the compression plate opposite to the suction and pressure regions. The vane-cell pump is characterised in that the surface (17; 19) of the compression plate (13; 15) which faces the rotor (5) has a concave shape in the unpressurised state of the vane-cell pump (1).
