Distributing member having a resiliently backed lamellar skirt, for mixing valves

Claim 1

A distributing member for mixing valves having inlet ports, comprising a support and control member, a peripherally interrupted flexible lamellar skirt made of a resiliently yielding material, said flexible lamellar skirt being connected at least at one end to said support and control member and extending around said support and control member, and being intended to cooperate with the inlet ports of the valve to open and close said inlet ports according to the position of said support and control member, and between said lamellar skirt and said support and control member a compressed resilient material, extending substantially the entire extent of said lamellar skirt, whereby a resilient backing action is exerted substantially onto the whole surface at least of that portion of the skirt which is active in cooperating with said inlet ports, said support and control member having a seat, said lamellar skirt having at one end a collar that encloses said seat, and the mutually facing surfaces of said seat and collar having a non-circular shape forming a non-rotatable coupling, whereby said lamellar skirt can be mounted onto said control member in different positions always being prevented from rotating with respect to said control member.
