Windshield washing system for motor vehicles, particularly for headlights
First Claim
1. Windshield washing system for motor vehicles, particularly for headlights, comprising:
- a jet nozzle assembly including a nozzle support for moving a jet nozzle from a rest position to a working position and a valve comprising a valve cover which is moved, along with the nozzle support, by pressurized cleaning liquid, but which, immediately before the jet nozzle reaches a working position, engages a fixed stop and is thereby separated from a position on the nozzle support in which it closes a passageway of the nozzle support;
wherein, the fixed stop is mounted at a free end portion of a fixed shaft-shaped holding element and engages an edge defining an opening in the valve cover through which the holding element extends with play; and
wherein, is further included a receiving element which is sealingly mounted on the valve cover, the receiving element being arranged in the passageway of the nozzle support, there being a space between the receiving element and an interior surface defining the passageway of the nozzle support, so as to leave the space between the receiving element and the interior surface defining the passageway through which the cleaning liquid can flow; and
wherein, the shaft-shaped holding element, when the jet nozzle is in the rest position, extends into the receiving element through an opening therein.

Abstract
A windshield washing system for a motor vehicle which moves a jet nozzle (1) from an inward rest position to an outward working position by pressure applied to a cleaning liquid. A valve cover (4) of a valve is moved, together with a nozzle support (2) by the pressure of the cleaning liquid and holds a passageway of the nozzle support closed until the valve cover engages a fixed stop (5) and the valve cover of the valve then opens. The stop is on a fixed shaft-shaped holding element (7) which, in the rest position of the jet nozzle, extends into a receiving element (9). The receiving element is inserted into a passageway of the nozzle support and is sealed, by an inner side of the valve cover. When the jet nozzle is in its working position, cleaning liquid flows through a passage space between the receiving element and the nozzle support to the jet nozzle.
