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