Abstract
A faucet for mixing hot and cold water includes a valve casing, cold and hot water inlet pipes coupled to the valve casing, first and second outlet pipes coupled to the valve casing, a valve housed in the valve casing and having a fixed plate and a movable plate, and an actuator for angularly moving the movable plate. The fixed plate has at least one cold water passage hole communicating with the cold water inlet pipe, at least one hot water passage hole communicating with the hot water inlet pipe, a first outlet hole communicating with the first outlet pipe, and a second outlet hole communicating with the second outlet pipe. The movable plate is held rotatably slidably against the fixed plate in watertight relation and has a recess defined in the surface thereof slidably contacting the fixed plate. When the movable plate is angularly moved by the actuator, at least one of the cold and hot water passage holes is brought into selective communication with the first and second outlet holes through the recess.
