Abstract
A faucet includes a valve cartridge having a housing with an inlet and outlet thereto. A valve plate is movable in the housing with respect to a fixed valve seat to control the quantity of fluid delivered from the inlet to the outlet. A bearing plate is positioned against the valve plate, a handle being provided on a handle bearing support to control the valve plate. A gasket between the valve seat and the housing is preloaded to provide a fluid-tight seal between the valve plate and the valve seat and a predetermined amount of friction therebetween. In manufacturing such a valve cartridge wherein the housing and the handle bearing support are formed of plastic, the parts are assembled and an ultrasonic welding mechanism is operated fixedly to secure the handle bearing support to the housing. It is preferable that the valve cartridge have a cylindrical housing in which the valve means are located and a base which carries the housing having its periphery confined within the periphery of the housing, and being recessed to define flange means for accepting fasteners used in mounting the valve cartridge. Where the valve cartridge is to be used to control the quantity and ratio of two liquids, two inlets to the housing would be provided. A fluid control member is usable in one orientation to admit one liquid to one inlet and the other liquid to the second inlet. By changing the orientation of such fluid control member, the liquid from the first duct is delivered to the second inlet, and the liquid from the second duct is delivered to the first inlet.
