Abstract: A washer fluid pump (2) for a windshield washer system (3) of a motor vehicle has ventilation ducts (25, 25?) which are arranged in a housing (17) parallel to the longitudinal axis. The ventilation ducts (25, 25?) open out behind bulkheads (21, 22) which are likewise arranged parallel to the longitudinal axis. The bulkheads (21, 22) bridge a constriction (20), which is arranged between an electric motor (15) and a pump stage (16), of the housing (17). In this way, the electric motor (15) is reliably protected against spray water. The washer fluid pump (2) can also be produced in a particularly cost-effective manner.

Abstract: In the case of a window cleaning system for a motor vehicle, a washing fluid line (6) is manufactured integrally with plug-type coupling parts (8). Movable components and a sealing ring (15) are arranged on bushing-type coupling parts (9). The bushing-type coupling parts (9) are arranged on a washing fluid pump (2), on washing nozzles (4) and on a T connector (7). By this means, the window cleaning system is constructed in a particularly simple manner and can be manufactured cost-effectively.

Abstract: In a washer fluid pump (2) for a window cleaning system (3) of a motor vehicle, a ventilation duct (21) of an electric motor (9) is guided in a labyrinth from a first plane (22) arranged in the electric motor (9) into the environment via a second plane (24) arranged in a collecting space (23). For this purpose, the ventilation duct (21) has two first sections (20) which lead vertically from the electric motor (9) into the collecting space (23), and two second sections (26) which open out vertically from the collecting space (23) into the environment. The first and the second sections (20, 26) are offset with respect to one another by 90°, so as to prevent an infiltration of spray water into the electric motor (9).

Abstract: In a device (1) for cleaning a window (2) or a lens of a motor vehicle, a wash nozzle (5) is of spherical design and is held in a ball socket (13) of a nozzle stem (4). The wash nozzle (5) produces a fan-type jet (6) and can be adjusted by an angle of inclination ? and a tilting angle ? in relation to the nozzle stem (4). The device can be freely adjusted to different designs of the motor vehicle.

Abstract: A washer fluid pump (2) for a window cleaning system includes two ventilation openings (13, 14) arranged in a housing (5) and linked with a single opening (15) arranged on the inside. A ventilation duct (18) has two sections (16, 17) arranged tangentially to the housing (5). The ventilation openings (13, 14) are separated from each other by a partition (19). This design makes it possible for the housing (5) to have a large ventilation cross section and avoids splashed water penetrating the housing (5).

Abstract: In a window cleaning system for a motor vehicle, having a dual pump (2) and having a valve (7) which is switched by the dual pump (2), a pressure surge which is generated during the switching of the valve (7) is conducted into the dual pump (2). For this purpose, valve seats (22, 23) are connected to inlets (25, 26) of the valve (7). Conducting the pressure surge into the dual pump (2) prevents that, during the switching of the valve (7), washer fluid passes onto a window (15, 16) which is not to be sprayed.
