<p>The mixing valve includes a fixed valve plate (7) of hard material provided with passage openings (7a) communicating with two supply pipes (3), a plastic slide (9) connected to a control mechanism (18), (19), (20) and sliding against a control guide ring (15), and at least a movable disk (8) of hard material fixed to the slide (9) and having openings (8a) therethrough cooperating with the passage openings (7a) of the fixed plate (7) so as to regulate the delivered water flow and the mixing ratio of the liquids fed in the faucet. The slide (9) has a cavity (10) where water is collected and at least an outlet opening (12) or (13) facing the guide ring (15). The guide ring (15) has a window (16) facing the outlet opening (12) or (13) of the slide (9) and a section of slots (14a) and blades (14) arranged like comb teeth. The slots (14a) extend themselves from the window (16) toward a space (2) surrounding the slide (9) and communicating with a spout connection (4). The slots (14a) are positioned to be at least partially covered by the slide (9) when the slide (9) is next to the closed position thus producing a total or partial closure device.</p> |
