For this purpose, the valve (20) is provided with a piston (19) which is axially movable in a direction of flow and comprises a valve head (30), the cleaning jet channel (34) extends in the hollow piston (19) and the valve head (30) comprises at least one water inlet orifice (33) towards the cleaning jet channel (34).

Abstract: A siphon type of drying gun includes an arc diverter disposed between an inner end surface in an accommodation space in a body of the gun and a flared hole. A rear cover having a flange is screwed into the body. An exhaustion gap is defined between the flange of the rear cover and the arc diverter. A front tapered hole in the rear cover corresponding to the arc diverter to guide the compressed air admitted into the exhaustion gap to flow by following the arc diverter and taking a turn into the flared hole so to produce siphon effects against ambient air to reduce noise level.

Abstract: A shower head for a hand-held shower attachment contains, in the center of its jet disc, an insert with three individual nozzle bodies. Each individual nozzle body is designed for discharging an individual jet. To this end, it has a continuous jet opening. Each of these in individual nozzle bodies is mounted in a manner that enables it to move relative to the shower head and to the jet disc, and is placed in rotation by a water-driven rotor. Said continuous jet opening extends at an angle to the rotation axis of the individual nozzle body. When the individual nozzle body rotates, the jet exiting there from moves on an envelope of a cone. Each individual nozzle body, contains an aerating device that aspirates the air immediately next to the outlet opening and, inside the individual nozzle body, mixes the air with the water entering this individual nozzle body. As a result, the individual nozzle body discharges an aerated jet.
