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 a 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. A noise reducing assembly including a plurality of overlapping screens is disposed within the surface cavity of the second disc. The assembly includes a plurality of overlapping screens with at least one protrusion extending from the screens into the flow passageway between the inlet and outlet openings while maintaining a free minimum passageway to thereby reduce the noise level during operation of the water faucet.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
165 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 a water outlet opening connected on one side to a valve manifold and on the other side directed toward 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: a noise reducing assembly disposed within the surface cavity of the second disc and including at least one integrally formed screen basket and at least one protrusion being in the form of a raised section of screen which extends towards the first disc into the flow passageway between the inlet and outlet openings while maintaining a free water flow passageway between said raised section, said screen and said stationary disc to thereby reduce the noise level during operation of the water faucet.
Claim 2
Dependent Claim
165 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 a water outlet opening connected on one side to a valve manifold and on the other side directed toward 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: a noise reducing assembly disposed within the surface cavity of the second disc and including at least one integrally formed screen basket and at least one protrusion being in the form of a raised section of screen which extends towards the first disc into the flow passageway between the inlet and outlet openings while maintaining a free water flow passageway between said raised section, said screen and said stationary disc to thereby reduce the noise level during operation of the water faucet.
Claim 3
Dependent Claim
