Faucet valve and valve cartridge

Claim 2

A faucet valve, comprising: a metal housing having a concentric axial bore including an internal annular shoulder, a cylindrical stationary plastic valve member within said housing on said shoulder having an axially off-set inlet bore and an enlarged outlet counterbore coaxially aligned with said inlet bore, a rotatable cylindrical plastic valve member within said housing having a body portion rotatably engaging said stationary valve member including the opening to said counterbore having an inlet port equally offset and alignable for communication with said stationary member outlet counter bore, a transverse outlet port communicating with said inlet port and said rotatable valve member having an integral axially projecting stem portion, an annular resilient sealing member within said stationary valve member counterbore resiliently biased against said rotatable valve member, sealing the communication between said stationary and rotatable valve member, and an annular plastic closure member within said housing received over said rotatable member portion, retaining said rotatable member within said housing.

Claim 3

The faucet valve defined in claim 1, characterized in that said stationary valve member includes an axially projecting annular lip adjacent the periphery of said stationary member and said rotatable valve member rotatably received within said lip.

Claim 4

The faucet valve defined in claim 2, characterized in that said stationary member lip extends beyond the outlet portion of said rotatable valve member and includes an outlet port communicating with the outlet port of said rotatable valve member.

Claim 5

The faucet valve defined in claim 1, characterized in that said stationary and closure members have opposed peripheral rim portions defining an internal cylindrical chamber, and said rotatable valve member located within said chamber and supported for rotational movement about the axis of said stem portion.

Claim 6

The faucet valve defined in claim 1, characterized in that said rotatable valve member inlet port is kidney-shaped and the outlet port is generally rectangular.

Claim 7

A faucet valve, comprising: a tubular metal housing having a first cylindrical inlet bore communicating with a larger cylindrical bore concentric with said first bore and defining an annular shoulder therebetween, a stationary cylindrical plastic valve member located within said second housing bore against said housing shoulder having an axially off-set inlet bore receiving fluid from said first housing bore and a larger outlet counterbore concentric with said off-set inlet bore, a rotatable cylindrical valve member having an enlarged end portion within said second housing bore against said stationary valve member having an axially off-set inlet port rotatable relative to said housing into coaxial communication with said stationary member counter bore, a transverse outlet port and an axially projecting cylindrical stem portion, an annular sealing member located within said stationary valve member counterbore sealing the communication between said stationary and rotatable valve members, and a fixed annular closure member within said housing second bore encircling said stem portion and retaining said rotatable and stationary valve members within said housing.

Claim 8

A faucet valve, comprising: a tubular metal housing having a first cylindrical inlet bore communicating with a larger cylindrical bore concentric with said first bore and defining an annular shoulder therebetween, a stationary cylindrical plastic valve member located within said second housing bore against said housing shoulder having an axially off-set inlet bore receiving fluid from said first housing bore and a larger outlet counterbore concentric with said off-set inlet bore, a rotatable cylindrical valve member having an enlarged end portion within said second housing bore against said stationary valve member having an axially off-set inlet port rotatable relative to said housing into coaxial communication with said stationary member counter bore, a transverse outlet port and an axially projecting cylindrical stem portion, an annular sealing member located within said stationary valve member counterbore sealing the communication between said stationary and rotatable valve members, and a fixed annular closure member within said housing second bore encircling said stem portion and retaining said rotatable and stationary valve members within said housing.

Claim 9

The faucet valve defined in claim 6, characterized in that said stationary and closure members have axially projecting annular rim portions adjacent their peripheries receiving said enlarged rotatable valve member portion and having a transverse outlet port communication through said rotatable valve member with inlet port.

Claim 10

The faucet valve defined in claim 6, characterized in that said annular sealing member has a first conical inlet port and a second cylindrical outlet port defining a shoulder and said sealing member biased against said rotatable valve member by an annular spring received within said conical inlet port.

Claim 11

A faucet valve cartridge, comprising, in combination: a first stationary cylindrical plastic valve member having an axially off-set inlet bore through one axial end communicating with a larger concentric outlet bore through the opposed end of said stationary valve member and an axially projecting annular peripheral rim encircling said opposed valve member end, a second rotatable plastic valve member having an enlarged cylindrical end portion received within said stationary valve member rim portion having an inlet port axially off-set to communicate with said stationary valve member outlet bore upon rotational alignment, said rotational valve member having an axially projecting integral stem portion, and a third annular retainer plastic valve member encircling said rotational valve member stem portion having a peripheral rim portion projecting toward said stationary valve member rim portion and enclosing said rotatable valve member, and said opposed rim portions having a radial outlet port communicating with said rotational valve outlet port.

Claim 12

A faucet valve cartridge, comprising, in combination: a first stationary cylindrical plastic valve member having an axially off-set inlet bore through one axial end communicating with a larger concentric outlet bore through the opposed end of said stationary valve member and an axially projecting annular peripheral rim encircling said opposed valve member end, a second rotatable plastic valve member having an enlarged cylindrical end portion received within said stationary valve member rim portion having an inlet port axially off-set to communicate with said stationary valve member outlet bore upon rotational alignment, said rotational valve member having an axially projecting integral stem portion, and a third annular retainer plastic valve member encircling said rotational valve member stem portion having a peripheral rim portion projecting toward said stationary valve member rim portion and enclosing said rotatable valve member, and said opposed rim portions having a radial outlet port communicating with said rotational valve outlet port.

Claim 13

The valve cartridge defined in claim 9, characterized in that said stationary valve member outlet bore includes a spring biased annular sealing member sealing the communication between said stationary valve member and said rotatable valve member.
