<p>This invention pertains to a mixer valve with electronic control, which incorporates a group of valves (27) situated in a housing (26) provided in the valve body, placed axially to the coupling (22) defining the water outlet duct towards the supply mouth. The group of valves is made up of a diaphragm valve (30) made of elastic material, essentially in the shape of a small bowl placed flush with a valve seat (32) inside the outlet duct (21), and of a stop valve (31) controlled by an electromagnet (29). The diaphragm valve (30) delimits an internal chamber (35) which communicates on one hand (A) with a mixed water supply duct (24) and on the other (B) with an outlet port (C) which extends into the water outlet duct (21) and is opened and closed by the stop valve. The diaphragm valve (30) is designed to expand and contract radially according to the differences in pressure inside and outside said chamber following the opening/closing of the input port by means of the stop valve. <IMAGE></p> |
