Abstract
A spray apparatus is described for spraying liquid products having a prods container disposed in a casing cover. A spray head is provided with a products channel, and an air supply line connected to a pressure connection of an air pump. The spray head has a closure part, a control part displaceable towards the closure part and mechanisms for introducing compressed air into the nozzle of the spray head. The spray apparatus rapidly reduces the compressed air producing the spray jet when the spray apparatus is switched off, so that there is no subsequent spraying or dripping. In order to rapidly reduce the compressed air, the closure part has a slide valve provided with pipe connections, and a control slider is positioned in the slide valve and is movable by means of the control part. The spray apparatus has a spraying position, a venting position, and a closure position, such that when in the closure position, the control slider is disposed in its uppermost position where it projects furthest out of the slide valve.
