Abstract
Abstract Abstract of the Disclosure Sanitary water valve with a self-clipping screen arranged in the recess and made out of elastic material. The screen preferably has a conical outer part and an inner ring-part, which on one hand go over into the screen bottom and on the other hand form a clipping reinforcement, the diameter of which is greater than the recess.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
143 words
A sanitary water valve comprising a valve body with control elements which comprise at least two discs, one of the discs being fixedly disposed and being provided with inlet apertures which on one side are attached to water supply pipes and on the other side are directed against the other of the discs, and said other of the discs being movably arranged on said one disc and having for deflecting functions a surface duct which can be brought simultaneously to overlap the inlet apertures and an outlet aperture in said one disc, and in which there is at least one sieve, wherein said sieve has lineal dimensions greater than the corresponding lineal dimensions of said surface duct so as to provide a compressive fit in said surface duct, and said sieve has a height dimension less than the depth of said surface duct.
Claim 2
Dependent Claim
143 words
A sanitary water valve comprising a valve body with control elements which comprise at least two discs, one of the discs being fixedly disposed and being provided with inlet apertures which on one side are attached to water supply pipes and on the other side are directed against the other of the discs, and said other of the discs being movably arranged on said one disc and having for deflecting functions a surface duct which can be brought simultaneously to overlap the inlet apertures and an outlet aperture in said one disc, and in which there is at least one sieve, wherein said sieve has lineal dimensions greater than the corresponding lineal dimensions of said surface duct so as to provide a compressive fit in said surface duct, and said sieve has a height dimension less than the depth of said surface duct.
Claim 3
Dependent Claim
89 words
A sanitary water valve according to claim 1, wherein said sieve is in the form of a unitary piece of resilient material and is shaped like a kind of basket, said sieve in the non-mounted state having a conical outer annular portion and a conical inner annular portion which passes on one side into the sieve bottom and on the other side forms, with the outer annular portion, a clamping rim whose diameter is greater than that of the surface duct to provide a compressive fit when mounted therein.
Claim 4
Dependent Claim
17 words
A sanitary water valve according to claim 1, wherein the sieve is constructed as a hollow ring.
Claim 5
Dependent Claim
21 words
A sanitary water valve according to any one of claims 1, 2 and 3, wherein the sieve is of mesh material.
Claim 6
Dependent Claim
21 words
A sanitary water valve according to any one of claims 1, 2 and 3, wherein the sieve is of plastics material.
Claim 7
Dependent Claim
20 words
A sanitary water valve according to any one of claims 1, 2 and 3, wherein the sieve is of metal.
