ABSTRACT:
A simple plastic valve cartridge and faucet valve utilizing a concentric metal pipe having an enlarged bore receiving the valve cartridge. The cartridge includes a cylindrical stationary valve member having an axially off-set inlet bore and an opposed axially projecting peripheral rim portion, a rotatable valve member having an inlet port axially off-set for communication with the port of the stationary valve member and a transverse outlet port, and an annular closure member having an axially projecting peripheral rim portion cooperating with the stationary valve member rim portion to define a cylindrical chamber receiving the rotatable valve member. The valve cartridge thus eliminates the requirement of complex machined metal parts while providing the anti-noise and flow features of the prior art.
