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 radial pump stage having a pump impeller which includes a plurality of guide vanes that extend in the axial direction. A sensor cleaning device having a radial pump stage of this kind, and to a vehicle having a radial pump stage of this kind or a sensor cleaning device of this kind.

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.

Abstract: A fluid-conveying device for conveying a fluid from a tank includes: a first fluid-conveying pump; a swirl pot; and a second fluid-conveying pump having a drive region and a conveying region coupled to the drive region. The fluid is conveyable from the swirl pot by the first fluid-conveying pump, and the conveying region is configured and arranged so as to be drivable by the drive region.
