<p>Valve for venting the air from the intake pipe (10) of an intake orifice for hydro-massage, comprising a valve body (24) which is connected on one side to the intake pipe (10) and, on the other side can be made to communicate with the atmosphere by a diaphragm closure member (34) which is associated with a wall provided with holes (32) for bleeding the air. The closure member (34) can assume two positions which correspond to opening and closing of the valve (22). The valve (22) is opened by the flow of air which rises in the valve body (24) by the action of intake of water in the intake pipe (10), whereas the valve (22) is closed by the depression generated by priming of the intake pump (12). <IMAGE></p> |
