Abstract

The mixing valve includes a fixed valve plate of hard material provided with passage openings communicating with two supply pipes, a plastic slide connected to a control mechanism and sliding against a control guide ring, and at least a movable disk of hard material fixed to the slide and having openings therethrough cooperating with the passage openings of the fixed plate so as to regulate the delivered water flow and the mixing ratio of the liquids fed in the faucet. The slide has a cavity where water is collected and at least an outlet opening facing the guide ring. The guide ring has a window facing the outlet opening of the slide and a section of slots and blades arranged like comb teeth. The slots extend themselves from the above-mentioned window toward a space surrounding the slide and communicating with a spout connection. The slots are positioned to be at least partially covered by the slide when the slide is next to the closed position by thus producing a total or partial closure device.

Dependent claims

A faucet valve characterized by:

a fixed valve seat means having at least one passage opening in communication with at least one supply line;
a movable valve plate slidably mounted on said fixed valve seat means to selectively close or open said at least one passage;
a slide member fixed to said movable valve plate having a cavity in communication with said at least one passage when said valve plate is positioned to open said at least one passage and an outlet from said cavity;
a control guide member for guiding said slide member and having a window therein in communication with said outlet of said slide member;
said window having a slotted section with alternating blades and slots positioned sufficiently close together to reduce noise as liquid flows therethrough and being positioned to be selectively intercepted by said slide member to be substantially closed off by said slide member from an outlet space exteriorly positioned from said slide member when said slide member is positioned to move said valve plate to substantially close off said at least one passage;
and
a control means for moving said slide member.
