Abstract: An adjustable vane pump, in particular an oil pressure pump, with a suction side and a pressure side, with a housing and a rotor supported in the housing so as to be rotatable about a rotor axis. 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.

Abstract: An adjustable vane pump, in particular an oil pressure pump, with a suction side and a pressure side, with a housing and with a rotor, which is supported in the housing so as to be rotatable about a rotor axis and carries at least one vane supported movably in a radial direction, wherein the housing comprises a housing floor and a housing cover transversely to the rotor axis, and wherein an adjustment cage that is arranged between the housing floor and the housing cover, encloses the rotor and the vane and is adjustable transversely to the rotor axis is provided in the housing, wherein the housing and the adjustment cage delimit a pressure chamber fluidically connected to the pressure side, wherein a restoring element is provided, which pushes the adjustment cage into a base end position, and wherein the adjustment cage is deflected from the base end position when a limit operating variable is exceeded in the pressure chamber.
