Abstract: A valve pump unit having an electric motor, a reduction gearbox driven by the electric motor, a first pump stage driven by the electric motor, a second pump stage driven by the electric motor, a multiway valve adjusted via the reduction gearbox and having heat transport medium channels for providing at least two switching positions between a first heat transport medium circuit and a second heat transport medium circuit, and also a common housing section for accommodating the electric motor, the multiway valve, the reduction gearbox and also the first pump stage and the second pump stage. In pumping operation, the electric motor is rotated in a first direction, and the reduction gearbox is uncoupled from the electric motor via a freewheel. The reduction gearbox may be operated in a second direction of rotation of the electric motor, to adjust the multiway valve.

Abstract: A valve/pump unit is proposed, having an electric motor for driving at least one pump stage, at least one first pump stage drivable by the electric motor for conveying a heat transport medium in a first heat transport medium circuit, an adjustable multiway valve with heat transport medium channels for providing at least two switching positions between the first heat transport medium circuit and a second heat transport medium circuit of a heat transport medium system, and a common housing section for accommodating the electric motor, the multiway valve and the pump stage. The multiway valve is joined to the electric motor in such a way that the multiway valve encloses the electric motor.

Abstract: A distributing device for supplying pressurized liquid to individual cleaning locations of a vehicle is proposed, the distributing device defining individual positions into which a distributor is selectively adjustable relative to a housing in which the distributor is arranged and driveable. Here, the individual positions of the distributor include a multiplicity of distributing positions and a bypass position and a shut-off position. In the bypass position, the distributor forms a bypass for preventing a discharge of the liquid to one of the cleaning locations and for returning the liquid to a tank. By contrast, in the shut-off position, the distributor prevents both the discharge and the return. Also proposed are a liquid-distributing actuator, a cleaning device, a vehicle, and a method for operating the cleaning device.

Abstract: A valve/pump unit having a single electric motor for driving at least one pump stage and for adjusting a multiway valve, a reduction gearbox, which is driven by the electric motor, at least one first pump stage which is driven by the electric motor for conveying a heat transport medium in a first heat transport medium circuit, an adjustable multiway valve that is adjusted via the reduction gearbox, and having heat transport medium channels for providing at least two switching positions between the first heat transport medium circuit and a second heat transport medium circuit. In pumping operation in a first direction of rotation of the electric motor, the reduction gearbox is uncoupled from the electric motor via a freewheel. The reduction gearbox is operated in a second direction of rotation of the electric motor, opposite to the pumping operation, to adjust the multiway valve.

Abstract: A distributing device D for supplying a pressurized liquid to individual cleaning locations of a vehicle. Here, the distributing device includes a housing with an electric-motor-drivable distributor arranged therein and also includes liquid-receiving and liquid-guiding means. Here, the distributor is rotatably adjustable relative to the housing into individual defined positions in which a feed connection AZ charged with liquid pressure is fluidically connected to one of multiple discharge connections ARSi, ARSi+1 . . . ARSi+n for providing a supply to an associated cleaning location. Here, the distributor, which is of substantially cylindrical form, directs the liquid—according to rotational adjustment—via radially circumferential liquid-receiving and liquid-guiding means to one of the discharge connections ARSi, ARSi+1 . . . ARSi+n.
