Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 198 words
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.
Claim 2
Dependent Claim 198 words
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.
Claim 3
Dependent Claim 31 words
A distributing member as set forth in claim 1, wherein said skirt has inwardly directed end flanges which enclose said compressed resilient material in order to hold the same in place.
Claim 4
Dependent Claim 32 words
A distributing member as set forth in claim 1, wherein said support and control member has protruding tabs which enclose said compressed resilient material in order to hold the same in place.
Claim 5
Dependent Claim 25 words
A distributing member as set forth in claim 1, wherein said lamellar skirt has recesses located in the middle region of the outer surface thereof.
Claim 6
Dependent Claim 24 words
A distributing member as set forth in claim 1, wherein said compressed resilient material has recesses in order to increase the yielding capacity thereof.
Claim 7
Dependent Claim 31 words
A distributing member as set forth in claim 1, wherein said lamellar skirt is made of a synthetic material of a type subject to the phenomenon of the so-called "cold flow".
Claim 8
Dependent Claim 41 words
A distributing member as set forth in claim 1, wherein said compressed resilient material is selected from the group of materials comprising soft rubber, soft materials, materials made soft by a spongy structure and materials made soft by a cellular structure.
