Abstract: Sensor cleaning system for cleaning sensors, in particular vehicle sensors, and associated method, characterized by a liquid reservoir for holding a cleaning liquid, and including a control unit for activating a switch unit and including at least one nozzle for spraying at least one sensor, the switch unit being provided between the liquid reservoir and the at least one nozzle, a liquid line being provided between the liquid reservoir and the switch unit and at least one nozzle line being provided between the switch unit and the at least one nozzle.

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: A rotor for a vane cell pump—in particular, for a vacuum pump—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.

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.

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.
