At least one vane is supported for movement in a radial direction. The housing comprises a housing floor and a housing cover transversely to the rotor axis, and an adjustment cage is arranged between the housing floor and the housing cover.

Adjustable vane pump

A rotor for a vane cell pump&#x2014;in particular, for a vacuum pump&#x2014;with a base body that is made of plastic and can be driven by rotation, and that rotates about an axis of rotation during operation, wherein the base body comprises a guiding section for slidably receiving a pump vane and wherein the base body is flanked in the direction of the axis of rotation by a first bearing surface and a second bearing surface, wherein the second bearing surface comprises bearing sections that are at a distance from one another and that lie on a circular path that is arranged concentrically to the axis of rotation.
