Abstract: A solenoid valve unit having at least four solenoid valves each having an electromagnet and each being fluidically connectable via an associated outlet to one of the cleaning points of a vehicle, a housing having at least one central supply line with at least one fluid inlet for providing a pressurized fluid in the supply line. The solenoid valves are joined to the housing transversely with respect to the supply line. Two solenoid valves, which lie opposite each other and are arranged transversely with respect to the supply line and between which the supply line is located, form a modularly extended pair of solenoid valves, the common housing portion of which is extended either at one end or at both ends of the supply line by a housing portion of a further pair of solenoid valves by a joining connection and/or an integrally bonded connection.

Abstract: A distributing device having a housing having an inlet connection and a plurality of outlet connections, and an electromotively drivable, rotatably adjustable distributor which is arranged therein in the form of a disk, on which a liquid receiving and liquid guiding device is formed. The distributing disk is rotatably adjustable into defined positions relative to the housing. The liquid receiving and liquid guiding device includes a front radial groove which controls the liquid to the desired locations of the distributing device. The radial groove is in the form of an open profile and extends from an external face, on the radial circumference, of the distributing disk into the distributing disk. The inlet connection supplies pressurized liquid to a radial gap which the distributing disk forms with the housing at the radial circumference and which guides the liquid to the radial groove. A liquid-distributing actuator includes such a distributing device.

Abstract: A method for operating an electric motor that drives a displacement pump stage to deliver a liquid through a hydraulic system to supply the liquid to at least one consumer. A periodically repeating pressure fluctuation of the liquid that occurs during delivery operation is at least partially compensated by virtue of the rotational speed of the electric motor being manipulated in accordance with the periodically repeating pressure fluctuation.

Abstract: A distribution device including: —a housing having an inlet port and a plurality of outlet ports and—an electromotively drivable, rotatably adjustable distributor which is arranged in the housing in the form of a disk on which liquid-receiving and liquid-guiding means are formed. The distributor disk is rotatably adjustable into defined positions relative to the housing here. The liquid-receiving and liquid-guiding means here include an end-face radial groove which directs the liquid to the desired locations in the distribution device. In this case, the distribution device additionally has a sensor arrangement for determining the position of the radial groove, wherein the sensor arrangement has a signal transducer which is fixed in position with respect to the housing and a metallic counterpart element which is fixed in position with respect to the distributor disk and interacts with the signal transducer.

Abstract: A distributing device for supplying a pressurized liquid to individual cleaning locations of a vehicle. The distributing device has a housing having an inlet connection, a plurality of outlet connections for the individual cleaning locations and a return connection, and an electromotively drivable, rotatably adjustable distributor which is arranged therein and which is in the form of a disk, in which liquid receiving means and liquid guiding means are formed. The distributor is rotatably adjustable relative to the housing in defined positions in order to allow or to prevent the supply of liquid. The disk controls or guides the liquid to the desired locations of the distributing device via a liquid receiving means and liquid guiding means at the front side in the form of a radial groove.

Abstract: A pump for delivering a liquid, having an electric motor with a stator and a rotor arranged inside the stator. The electric motor is accommodated in an electric motor housing. The stator has two end faces and an outer peripheral surface and there is formed between the electric motor housing and the outer peripheral surface of the stator an outer fluid channel through which the liquid can be delivered. The stator has on at least one of its end faces a connection to the electric motor housing.
