Reverse of the Vane pump principle, in which two vanes are adjustably arranged in the housing at an angle of 180°, which, together with two cams on the rotor, create two suction chambers and two pressure chambers (Figure S 72). The system does not allow for volume setting, but works very quietly. Pressure range up to around 200 bar.
