Abstract

A vane cell pump with a rotor ( 3 ) rotatably mounted in an adjustable stroke ring ( 1 ) and driven by a drive shaft ( 2 ) and with several vanes ( 4 ) is proposed, which vanes are mounted in a radially displaceable manner in radially running slots ( 12 ) of the rotor ( 3 ) and are subjected to rear vane chamber pressure. In accordance with the invention, it is provided that at least one forced guide element is allocated to one vane ( 4 ) for the radial movement of the vane ( 4 ) in such a manner that the forced guide element is integrated into the rotor ( 3 ) and/or into the drive shaft ( 2 ) without any effect on installation space.
