Abstract
Abstract A faucet valve in which a rotatable valve member has a spherical valve surface and a passage including an inlet in the spherical surface which is offset from the axis of rotation and rotatable into and out of registry with a similarly offset inlet port in the valve body, and a laterally extending outlet terminating in an annular channel in the spherical surface and communicating with an outlet port in the valve body. The annular channel on the valve surface defines a restricted passage through which water flows when there is only slight registry of the inlet ports in the valve member and valve body to create a back pressure which muffles turbulence and reduces noise.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
170 words
A faucet valve comprising a valve body, a valve chamber in said valve body having a concave spherical surface at its lower end, said valve body having an inlet port opening into said spherical surface and offset from the axis of said chamber, and an outlet port opening from said spherical surface and extending generally radially relative to said axis, a valve member rotatably supported in said valve body and having a spherical portion seated against said spherical surface, said valve member having a passage therethrough having its inlet in said spherical portion and offset from said axis whereby said inlet in said valve member is rotatable intO and out of registry with said inlet port, said spherical portion of said valve member having a band of reduced diameter spaced from said passage inlet to define an annular restricted channel between said valve member and valve body with said channel in constant communication with said outlet port, said passage in said valve member having its outlet terminating in said channel.
Claim 2
Dependent Claim
170 words
A faucet valve comprising a valve body, a valve chamber in said valve body having a concave spherical surface at its lower end, said valve body having an inlet port opening into said spherical surface and offset from the axis of said chamber, and an outlet port opening from said spherical surface and extending generally radially relative to said axis, a valve member rotatably supported in said valve body and having a spherical portion seated against said spherical surface, said valve member having a passage therethrough having its inlet in said spherical portion and offset from said axis whereby said inlet in said valve member is rotatable intO and out of registry with said inlet port, said spherical portion of said valve member having a band of reduced diameter spaced from said passage inlet to define an annular restricted channel between said valve member and valve body with said channel in constant communication with said outlet port, said passage in said valve member having its outlet terminating in said channel.
Claim 3
Dependent Claim
203 words
A faucet valve comprising a valve body having an upwardly opening cylindrical bore provided with a concave spherical bottom wall, said valve body having an inlet port opening into said bottom wall and offset from the axis of said bore, and an outlet port in said bottom wall, a valve member rotatable in said bore and having a spherical portion seated against said bottom wall, said valve member having a passage therethrough having its inlet in said spherical portion and offset from said axis so as to be movable into and out of registry with said inlet port upon rotation of said valve member, said spherical portion of said valve member having a band of reduced diameter spaced from said passage inlet to define a restricted channel between said valve member and valve body communicating at all times with said outlet port, said passage in said valve member having its outlet in said channel, said inlet and outlet in said valve member and said inlet and outlet ports in said valve body being relatively disposed so that water must flow through said restricted channel to said outlet port when said inlet in said valve member has only slight registration with said inlet port.
Claim 4
Dependent Claim
203 words
A faucet valve comprising a valve body having an upwardly opening cylindrical bore provided with a concave spherical bottom wall, said valve body having an inlet port opening into said bottom wall and offset from the axis of said bore, and an outlet port in said bottom wall, a valve member rotatable in said bore and having a spherical portion seated against said bottom wall, said valve member having a passage therethrough having its inlet in said spherical portion and offset from said axis so as to be movable into and out of registry with said inlet port upon rotation of said valve member, said spherical portion of said valve member having a band of reduced diameter spaced from said passage inlet to define a restricted channel between said valve member and valve body communicating at all times with said outlet port, said passage in said valve member having its outlet in said channel, said inlet and outlet in said valve member and said inlet and outlet ports in said valve body being relatively disposed so that water must flow through said restricted channel to said outlet port when said inlet in said valve member has only slight registration with said inlet port.
Claim 5
Dependent Claim
25 words
A valve according to claim 2 wherein said restricted channel extends entirely around said spherical portion and lies in a plane perpendicular to said axis.
Claim 6
Dependent Claim
49 words
A valve according to claim 2 wherein said inlet in said valve member extends generally parallel to said axis and said outlet extends generally perpendicular to said axis and is adapted to be brought into alignment with said outlet port in the full open position of said valve member.
