Abstract

The displacement pump has a rotary drive member (1) operated at a speed dependent upon that of a drive motor and a housing containing a first conveyor wheel (5) coupled to the rotary drive member for introduction of a torque. The first conveyor wheel forms a delivery chamber (7) with the walls of the housing alone or in conjunction with a second conveyor wheel (6), which has a low pressure side (8) connected with a pump inlet and a high pressure side (9) connected with a pump outlet. A delivery volume limitation of the pump is achived by using a magnet coupling (13-16), which couples the rotary drive member with the first conveyor wheel for transmission of the torque. A drive half (13,14) of the magnet coupling is connected with the rotary drive member and a driven half (15,16) with the first conveyor wheel, in both cases secure against twisting.
