Single-handle mixing valve |
摘要 |
A single-handle mixing faucet of the type having a rotatable axially movable hollow piston for the selection of the mixing ratio and flow volume includes improved seals for sealing between the walls of the valve casing and a cylindrical sleeve inserted into the valve casing. The seals are of two piece construction and include a rim-type molded body bent to follow the configuration of the sleeve and a sealing member which is carried by the molded body. Inlet apertures on the sleeve are longitudinal slots of specific configuration. Noise silencing is enhanced by use of perforated disks or a porous cylinder.
