Abstract
Abstract An improved water faucet having a valve body with control elements formed by two discs wherein the first disc is stationary and has water inlet openings and an outlet opening, connected on one side to the valve manifold. The other side is directed toward the second disc, which is movably arranged on the first disc. The second disc has a surface cavity overlapping the inlet openings and outlet opening of the first disc. Noise-reducing assembly including a plurality of overlapping screens, the wire orientation of each screen being angularly offset with respect to that of the other screens, the assembly being disposed within the surface cavity of the second disc with the wire screens spaced from the ceiling thereof to form a chamber which aids in reducing the cavitation noise of the valve.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
In a water faucet having a valve body with control elements formed by two discs, the first disc being stationary and having water inlet openings and water outlet opening connected on one side to a valve manifold and on the other side directed towards the second disc which is movably arranged on the first disc, the second disc having a surface cavity arranged and constructed to overlap the inlet openings and the outlet opening formed in the first disc, the improvement comprising: noise reducing assembly disposed within the surface cavity of the second disc and including a plurality of overlapping screens, the wire orientation of each screen being angularly offset with respect to that of the other screens; said noise reducing assembly being spaced a predetermined distance from the ceiling of said cavity defining a noiseisolating chamber within the cavity.
Claim 2
Dependent Claim
140 words
In a water faucet having a valve body with control elements formed by two discs, the first disc being stationary and having water inlet openings and water outlet opening connected on one side to a valve manifold and on the other side directed towards the second disc which is movably arranged on the first disc, the second disc having a surface cavity arranged and constructed to overlap the inlet openings and the outlet opening formed in the first disc, the improvement comprising: noise reducing assembly disposed within the surface cavity of the second disc and including a plurality of overlapping screens, the wire orientation of each screen being angularly offset with respect to that of the other screens; said noise reducing assembly being spaced a predetermined distance from the ceiling of said cavity defining a noiseisolating chamber within the cavity.
Claim 3
Dependent Claim
33 words
The water faucet according to claim 1 wherein said noise-reduciNg assembly includes a pair of overlapping metal screens positioned within said cavity to provide a perforated surface for cavitation bubbles to implode thereon.
Claim 4
Dependent Claim
19 words
The water faucet according to claim 2 wherein said screens are coupled together by at least one spot weld.
Claim 5
Dependent Claim
15 words
The water faucet according to claim 2 wherein said screens are coupled together by calendering.
Claim 6
Dependent Claim
41 words
The water faucet as recited in claim 1 wherein said overlapping metal screens are mounted in fixed position on a retaining ring, said retaining ring being of a size to provide a pressure fit to position said screen in said cavity.
Claim 7
Dependent Claim
153 words
