Abstract
A spray device (10, 56, 58) for a window or glass washing system has a spray nozzle (14) that has a nozzle bore (50) and is supported in a nozzle housing (12) with a water connection and has a device that prevents a returm flow and an uncontrolled escape of spraying water. The spray nozzle (14) is retained axially movably in the nozzle housing (12) and in the spraying operation is subjected to water pressure at a face end (24) toward the water connection (60), while with its other face end (26), it contacts a closure part (16, 38), which sealingly covers the nozzle bore (50) until it is brought, by an axial displacement of the spray nozzle (14), into an open position and uncovers the nozzle bore (50).
