Abstract: A single-handle faucet has a faucet housing with a mixing valve cartridge disposed therein. The valve cartridge includes a fixed sleeve and a movable stem. A two-part rising cap is connected to the valve stem. An operating handle extends through an opening in the rising cap and is pivotally connected to the sleeve. The two part rising cap is split into first and second parts which are joined along mating surfaces by cooperating pin and hole pairs. The rising cap opening is defined by adjoining slots formed in each of the first and second parts, allowing the rising cap to be assembled about a previously installed handle.

Abstract: A fluid valve for use in a two handle faucet assembly has a housing, a sleeve within the housing, a stem positioned within the sleeve with a handle portion extending outside of the sleeve and housing, and a reciprocal piston. Rotation of the stem causes reciprocation of the piston. A grommet-type seal is attached to the interior end of the sleeve, adjacent its inlet, and has a portion extending within the sleeve toward the axially movable piston. The seal portion extends in the direction of fluid flow through the valve with the piston closing against the direction of fluid flow onto the extending portion of the seal to effect opening and closing of the valve.
