  • Patent number: 12017621
    Abstract: Disclosed is a cleaning device for a washing apparatus arranged in a vehicle, comprising a housing with a chamber which is formed in the housing, is configured to be filled with cleaning fluid and is hydraulically connectable to at least one spray nozzle for the cleaning fluid, and with at least one heatable heating wire protruding at least in sections into the chamber. To obtain high functional reliability even at low temperatures and to permit particularly rapid and reliable deicing, a heat-conducting element is arranged in the chamber to enlarge a heat-transferring convection surface, said heat-conducting element absorbing the heat from the heating wire, and being at least partially, and preferably completely, surrounded by the cleaning fluid.
    Type: Grant

  • Patent number: 10065609
    Abstract: In a washer nozzle for a windshield washer system of a motor vehicle with a heating element held in a duct, a sealing compound for holding the heating element and a sealing element are manufactured from different materials and spaced apart from one another. Consequently, the sealing element may be manufactured from a material having poor heat conduction and the sealing compound from a material having good heat conduction. The washer nozzle has an especially long service life.

  • Publication number: 20170015283
    Abstract: In a washing nozzle for a window washing system, a spring element of a check valve is supported on a jet insert. A valve seat of the check valve is designed as a constricted cross-section of a washing fluid duct. This allows the check valve and the jet insert to be mounted in a particularly simple manner.

  • Patent number: 8430108
    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.

  • Patent number: 7669786
    Abstract: In the case of a windshield washer device (2) for a motor vehicle, a nozzle holder (6) is connected via a spring element (12) to a fastening flange (4) fastened to the motor vehicle. The nozzle holder (6) has a connection (9) for a washer fluid line (10). The spring element (12) is formed as a cross-sectional tapering (15) of a connecting element (14). The angle of inclination of the nozzle holder (6) and therefore the angle of inclination of a washer nozzle (7) arranged in the nozzle holder (6) can be adjusted via an adjusting means (13) at a distance from the spring element (12).
