    摘要： A cartridge-type faucet valve is provided which includes a housing with an inlet, an outlet and an insert assembly (or cartridge) seat interposed between the inlet and outlet and for cooperating with a portion of an insert assembly or cartridge to provide a seal between the inlet and outlet. The insert assembly or cartridge includes a stationary elongated sleeve and a stem mounted within the sleeve which is longitudinally movable over a range of travel between a closed position and a fully open position. One section of the stem co-acts with the sleeve to control the longitudinal position of the stem. Another section of the stem cooperates with an internal surface portion of the sleeve to provide a longitudinally extending flow passage for communicating from the inlet to the outlet. A seal piece is mounted on the stem and is adapted for engagement with a stationary seating surface adjacent one end of the sleeve. In operation, the seal piece is engaged with the seating surface only in the closed position for preventing flow to the flow passage. The insert assembly or cartridge further includes a seal interposed between the two above-mentioned stem sections for isolating the first mentioned section from the flow passage. The insert assembly or cartridge also includes a deformable seal for providing static sealing engagement with the insert assembly seat, the seal adapted to be in deformed static compression against the insert assembly seat when the insert assembly is assembled with the housing.

    摘要： A metering valve for controlling fluid flow is provided which includes a piston assembly disposed between a fluid inlet and a fluid outlet and mounted for relative movement within a tubular unit between a first open mode, a second open mode connecting the fluid inlet and outlet and a close mode. The assembly is biased to assume the close mode and assumes the first open mode when a predetermined first external form is applied to a valve actuating element forming a component of the metering valve. The assembly assumes the second open mode when the first external force is enhanced by a predetermined second external force applied to the valve actuating element. When the external forces are released, the piston assembly automatically returns to the close mode upon successively moving through first and second segments of travel relative to the tubular unit. The rate of travel during the first segment is substantially less than the rate of travel during the second segment. During the second segment of travel the relative motion of the piston assembly is substantially instantaneous to the close mode. The valve actuating element includes an elongate member having an exposed one end portion on which the predetermined external forces are applied, and a second end portion having a first valve component mounted thereon and actuated to a first open position when the first external force is applied. A second valve component is also mounted on the second end portion of the elongate member and is actuated to a second open position when the second external force is applied.
