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.
