Abstract

Abstract A faucet valve of the nonrise-type wherein the valve seat and the valve closure member are made of a wear- and corrosionresistant material, such as a high alumina ceramic. The mating faces of the valve seat and the valve closure member are highly polished so that when the faucet valve is in the closed position, the valve seat and the valve closure member are held together in sealing relationship by the inlet liquid pressure. The sealing elements are held together in a valve housing as a module which can be inserted and removed from the faucet body as a unit.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 274 words
A faucet valve of the type which includes, a generally cylindrical housing to be mounted inside a valve body having a liquid inlet and outlet, said housing having at least one opening in the wall thereof through which liquid can flow into the outlet; a valve seat loosely mounted in the bottom inlet end of the housing, said seat having a central passageway communicating with the liquid inlet; a valve closure member rotatably mounted on the valve seat and movable from a first position wherein the passageway is totally closed to a second position wherein the passageway has a maximum opening which communicates with the housing opening; said valve seat and valve closure member having smoothly polished mating surfaces so that liquid pressure acting on the inlet side of the valve seat is sufficient alone to provide a seal therebetween when the valve is in the closed position; seal means between tHe downstream side of the valve closure member and said housing; manually operable means connected to said valve closure member for moving the member between its first and second positions, wherein the improvement comprises an annular retainer having a generally L-shaped cross section, one leg of said L-shaped cross section extending upwardly and being press fitted within the lower cylindrical end of said housing, the upper end of said one leg engaging said valve seat to retain said valve seat and said valve closure member within said housing, the other leg of said L-shaped cross section extending radially outwardly beneath the lower end of said housing to support said housing and the components therein when said housing is mounted inside the valve body.
Claim 2
Dependent Claim 274 words
A faucet valve of the type which includes, a generally cylindrical housing to be mounted inside a valve body having a liquid inlet and outlet, said housing having at least one opening in the wall thereof through which liquid can flow into the outlet; a valve seat loosely mounted in the bottom inlet end of the housing, said seat having a central passageway communicating with the liquid inlet; a valve closure member rotatably mounted on the valve seat and movable from a first position wherein the passageway is totally closed to a second position wherein the passageway has a maximum opening which communicates with the housing opening; said valve seat and valve closure member having smoothly polished mating surfaces so that liquid pressure acting on the inlet side of the valve seat is sufficient alone to provide a seal therebetween when the valve is in the closed position; seal means between tHe downstream side of the valve closure member and said housing; manually operable means connected to said valve closure member for moving the member between its first and second positions, wherein the improvement comprises an annular retainer having a generally L-shaped cross section, one leg of said L-shaped cross section extending upwardly and being press fitted within the lower cylindrical end of said housing, the upper end of said one leg engaging said valve seat to retain said valve seat and said valve closure member within said housing, the other leg of said L-shaped cross section extending radially outwardly beneath the lower end of said housing to support said housing and the components therein when said housing is mounted inside the valve body.
Claim 3
Dependent Claim 292 words
A faucet valve of the type which includes, a valve body having a liquid inlet and outlet; a housing mounted inside the body and having at least one opening in the wall thereof through which liquid can flow into the outlet; a retainer cap engaged with said valve body to retain said housing inside the body; a valve seat loosely mounted in the bottom inlet end of the housing, said seat having a central passageway communicating with the liquid inlet; a valve closure member rotatably mounted on the valve seat and movable from a first position wherein the passageway is totally closed to a second position wherein the passageway has a maximum opening which communicates with the housing opening; said valve seat and valve closure member having smoothly polished mating surfaces so that liquid pressure acting on the inlet side of the valve seat is sufficient alone to provide a seal therebetween when the valve is in the closed position; and manually operable means including a valve stem connected to said valve closure member for moving the member between its first and second positions, wherein the improvement comprises: said housing having a lower portion and an upper portion made of plastic provided with a cylindrical bore to act as a bushing for said valve stem, the lower end of said upper portion terminating in a radially outwardly extending flange engaging the upper end of said lower portion, said flange being disposed to be pressed down on said lower portion by said retainer cap when said housing is mounted inside said valve body; and an O-ring mounted on said valve stem in engagement with said cylindrical bore for providing a seal between the downstream side of the valve closure member and said housing.
Claim 4
Dependent Claim 292 words
A faucet valve of the type which includes, a valve body having a liquid inlet and outlet; a housing mounted inside the body and having at least one opening in the wall thereof through which liquid can flow into the outlet; a retainer cap engaged with said valve body to retain said housing inside the body; a valve seat loosely mounted in the bottom inlet end of the housing, said seat having a central passageway communicating with the liquid inlet; a valve closure member rotatably mounted on the valve seat and movable from a first position wherein the passageway is totally closed to a second position wherein the passageway has a maximum opening which communicates with the housing opening; said valve seat and valve closure member having smoothly polished mating surfaces so that liquid pressure acting on the inlet side of the valve seat is sufficient alone to provide a seal therebetween when the valve is in the closed position; and manually operable means including a valve stem connected to said valve closure member for moving the member between its first and second positions, wherein the improvement comprises: said housing having a lower portion and an upper portion made of plastic provided with a cylindrical bore to act as a bushing for said valve stem, the lower end of said upper portion terminating in a radially outwardly extending flange engaging the upper end of said lower portion, said flange being disposed to be pressed down on said lower portion by said retainer cap when said housing is mounted inside said valve body; and an O-ring mounted on said valve stem in engagement with said cylindrical bore for providing a seal between the downstream side of the valve closure member and said housing.
Claim 5
Dependent Claim 100 words
A faucet valve as recited in claim 2 which further includes: an annular retainer having a generally L-shaped cross section, one leg of said L-shaped cross section extending upwardly and being press fitted within the lower cylindrical end of said housing, the upper end of said one leg engaging said valve seat to retain said valve seat and said valve closure member within said housing, the other leg of said L-shaped cross section extending radially outwardly beneath the lower end of said housing to support said housing and the components therein when said housing is mounted inside the valve body.
