摘要： A fill valve system with a float nested in a container connected to the fill valve and a siphon device passing water out of the container into the toilet tank, with the siphon device having an air vent dimensioned such that: (i) tank refilling is delayed until after the flush valve closes; (ii) the fill valve is not turned on by small leaks in the tank; and (iii) the fill valve turns off when it encounters large leaks in the tank.

摘要： A modulating intake valve having a low internal pressure drop used in conjunction with a gas compressor, including a valve body having a gas inlet and a gas outlet. A self modulating, hemispherical shaped poppet within the valve body moves closer or further from a valve seat to control the gas flow into the inlet and out of the outlet into the gas compressor. The hemispherical poppet valve functions as a check valve to close against the valve seat and prevent flow of gas and oil from the compressor through the valve body and out of the gas inlet. A modulating piston disposed in a cage located between the gas inlet and the gas outlet. A control gas inlet port opens into a passageway to direct control gas to a space between the piston and the cage set to move the piston and hemispherical poppet valve at a given pressure.

摘要： A flow limiter valve assembly comprising a housing defined by an end cap and a guide base, a fluid inlet orifice provided in the base and a fluid outlet orifice in the circumferential wall of the housing, with a fluid flow path defined from the inlet orifice to the outlet orifice. The valve assembly further comprises a spool mounted in the base of the housing and arranged to be axially moveable relative to the housing end cap and biasing elements to bias the spool away from the end cap. When the spool is biased away from the end cap, the fluid flow path is defined by a gap between the end cap and the spool such that fluid can flow from the inlet orifice through this gap to the outlet orifice.

摘要： A fill valve with pressure chamber having an open bottom end and a diaphragm at a top end such that falling water level in the toilet tank causes the diaphragm to flex in a first direction, thereby moving a sealing member to an open position, with a venturi in the fill valve keeping the sealing member in the open position until water refilling the tank causes the diaphragm to flex in a second direction, thereby moving the sealing member back to the closed position.

摘要： A bypass valve assembly for a turbine generator includes a valve body, bypass seats, valve stem, valve cap, bypass valve disc, bypass valves, and pressure seal head. The valve body defines a central bore and a plurality of passageways. Each passageway has an inlet smaller than its outlet. Each bypass seat is within the inlet of a corresponding passageway. The bypass seats have a higher wear resistance than the valve body. The valve stem is within the central bore. The valve cap is secured to the valve body. The bypass valve disc is secured to the valve stem. Each bypass valve has a base portion and a nose portion. Each nose portion defines a contoured surface area with a wear coating and extends into a corresponding passageway. The pressure seal head is disposed around the valve stem and defines steps having a wear coating.

摘要： A snorkel assembly for underwater exercise including a snorkel tube, a mouthpiece portion and a valve seat is provided. The mouthpiece portion is configured to connect to and be in gas-communication with the snorkel tube. The valve seat is disposed in the snorkel tube or between the snorkel tube and the mouthpiece portion. The valve seat comprises a valve piece and a seat portion. The buckle portion of the valve piece is buckled to a buckle seat of the seat portion. The valve piece hangs on the seat portion with the buckle seat as a fulcrum. The valve piece is in a normally-open state when bearing no pressure, and is closed only when a user exhales.

摘要： A bleed air valve comprises a piston that moves along a guide, where the piston includes a first surface and an opposing second surface. A pressure divider network includes a divider network inlet having an inlet cross sectional area in fluid communication with a fluid passage, a divider network outlet having an outlet cross sectional area in fluid communication with ambient pressure, and a network chamber in fluid communication with the divider network inlet and the divider network outlet. The network chamber has a pressure value between pressure at the divider network inlet and pressure at the divider network outlet. A shuttle valve includes a shuttle inlet and a shuttle outlet, where the shuttle outlet is in fluid communication with the first surface. An electromechanical valve receives a command signal and in response provides compressed air to an electromechanical valve output that is in fluid communication with the shuttle inlet.

摘要： A lock valve including a poppet valve element which is disposed within a spring chamber, a spring which biases the poppet valve element leftward, and a valve seat which comes into contact with the poppet valve element is disposed in a cavity formed in a valve body to mount a relief valve therein and is positioned further inward than the sleeve of the relief valve. The outer peripheral portion of the poppet valve element has hole portions formed therein at regular intervals. The outer peripheral portion of the valve seat, too, has hole portions formed therein at regular intervals. The valve portion of a solenoid valve is disposed between a passage which is in communication with the spring chamber and a passage which is in communication with a second flow passage open to a low-pressure region such as a hydraulic tank.
