ABSTRACT:
The invention relates to a vane pump, the volumetric delivery of which can be regulated by varying the axial width of the pump working chambers. The vanes are carried in an axially fixedly disposed vane-carrier which rotates with the rotor. An axial slide engages axial ends of the respective individual vanes to axially movably adjust the vanes and therewith the axial length of the pump working chambers.
