A spray device (10, 56, 58) for a window or glass washer system, having 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 return flow and an uncontrolled escape of spraying water, characterized in that the spray nozzle (14) is retained axially movably in the nozzle housing (12) and in the spraying operation is subjected to water pressure on one face end (24) oriented 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 this closure part is brought, by the axial displacement of the spray nozzle (14), into an open position and uncovers the nozzle bore (50).
