Abstract: A self-shutting egress valve comprises a hollow valve body having an annular valve seat provided in a lower portion thereof, a valve piston movably positioned within the valve body and having an escape valve provided on an upper portion thereof, and a push rod depending from the valve piston. The valve body has an orifice and a set of inlet apertures formed respectively on a top portion and around a lower periphery thereon. The valve piston carries an annular, elastic flow controlling element thereon which engages the walls of an upper chamber in the valve body. A set of apertures formed around an upper portion of the push rod is in communication with the escape valve thereabove. Pushing up on the push rod opens the escape valve and thrusts the valve piston upward into the upper chamber of the valve body causing fluid to flow downwards therethrough and also around the flow controlling element.

Abstract: A water faucet structure comprising a hollow housing having hot and cold water inlets and a water outlet, a pair of setting valves therein, and a spout tube with one end connected to the water outlet and the other end thereof containing an egress valve. The hot and cold water inlets are in communication with a mixing chamber formed within the housing via respective setting valves wherein hot and cold water are combined in predetermined proportions before issuing from the spout tube. Each setting valve comprises a valve body having a stem and a piston, a sliding element slidingly secured to a fixed retaining element, and a rotatable positioning element threadedly engaged with one end of the sliding element. The valve stem is slidingly positioned within an axial cavity on an opposite end of the sliding element with the valve piston urged against a corresponding valve seat formed within the housing by a spring.

Abstract: A faucet of which the displacement of the valve cock is controlled through pressure equilibrium effect, which includes a draw-off tap assembly comprised of a casing, a valve cotter, a valve cock, a sealing plug, wherein said valve cock is mounted on said valve cotter, and said valve cotter is set in a cavity defined by said casing and said sealing plug with the rear end of said valve cotter been arranged to protrude beyond the water passage of said sealing plug. The draw-off tap assembly is fixed at the water outlet of the faucet to control water supply while a water temperature and flow rate regulating means is set at a front position of the faucet.
