Abstract
An adjustable vane pump having a bowl-shaped hosing and having a rotor rotatably supported about a rotor axis and guiding at least one vane that is supported such that it can move in the radial direction. The housing includes a first thrust surface and a second thrust surface for the rotor, including the vane, which are transverse to the rotor axis. The second thrust surface is formed by a housing floor. The housing includes an adjustment housing, disposed between the thrust surfaces, which encloses the rotor, including the vane, and can be displaced transverse to the rotor axis, and includes a primary housing that encloses the adjustment housing. A suction intake and a pressure outlet are provided in the housing floor, and the axial extension of the primary housing is greater than the axial extension of the adjustment housing, the rotor, and/or the at least one vane.
