摘要： An implantable device controls the movement of fluid to an inflatable portion of a gastric band. The implantable device includes a body. The body has an inlet, an outlet and a valve seat positioned between the inlet and the outlet. The body defines a fluid passage from the inlet to the outlet. The implantable device also includes a diaphragm. The diaphragm has one or more edges coupled to the body. The diaphragm is made of an elastomeric material and capable of being moved between a closed position that blocks the valve seat and does not allow the fluid to move from the inlet to the outlet and an open position that does not block the valve seat and allows the fluid to move from the inlet to the outlet.

摘要： A valve for controlling a “guaranteed” back up pressurised liquid supply to a tank fed from another primary supply. The valve controls the quantity of water in the tank between a predetermined upper and lower level. The valve has an inlet and an outlet interconnected by a restricted passage controlled by a diaphragm. The passage is formed by a bore and a reciprocally operative rod is mounted therein. The rod is connected to a support lever which is spring biased to close the valve. The support lever has an operating weight element suspended therefrom by a depending cord. The operating weight has two sections, which have a combined weight providing substantially neutral buoyancy in water. The cord length between the lever and the lower operating weight sections determines the lower water level threshold. The cord length between the two weight sections determines the differential between the lower and upper level.

摘要： A valve (19) primarily designed as a float valve to control the flow of water under pressure into a cistern has an upstream chamber (22) and a downstream chamber (23). The upstream chamber (22) communicates an inlet (21) for mains water supply with outlets (17, 17A) and the downstream chamber (23) has an outlet (24) which is closed by a valve (25) when a float rises a float rod (14). A primary valve member assembly comprises a piston (3) to the downstream end of which a diaphragm (5) is attached. When the secondary valve (25) is closed pressure on diaphragm (5) causes piston (3) to close the inlet (21). When the secondary valve (25) is opened by the rising float the piston (3) is expelled from the inlet (21) allowing water to flow into the cistern through the upstream chamber (22).

摘要： Fuel shut-off device for use in a diesel fuel tank to discontinue fuel flow to a fuel pump comprises a valve seat forming a fuel flow opening for fuel to flow from the fuel tank to the fuel pump, a fuel control valve cooperably disposed relative to the valve seat to control fuel flow from the fuel tank to the fuel pump, and a spring biasing the fuel inlet valve to a closed position against the valve seat. A diaphragm is provided having a first valve-actuating side for moving the fuel inlet valve relative to the valve seat against bias of the spring and a second side. The second side is communicated to a control chamber having an inlet orifice that is communicated to the fuel tank and an outlet orifice that is communicated to said fuel pump. An inlet orifice valve is disposed in the fuel tank and is actuated to open the inlet orifice to the fuel tank when the fuel level is above a predetermined low level to cause the diaphragm to move toward the fuel inlet valve to move it to an open position relative to the valve seat against bias of the spring and actuated to close the inlet orifice to the fuel tank when the fuel level is at the predetermined low level to cause the diaphragm to move away from the fuel inlet valve to allow the spring to move the fuel inlet valve to the closed position to provide insufficient fuel flow to the fuel pump to maintain engine operation, thereby preventing air from being ingested into the fuel pump.

摘要： A liquid level responsive shut-off valve for filling a tank, such as a liquid propane tank, comprises a valve housing having an inlet passageway for connection to a source of liquid under pressure, an outlet passageway opening into the tank, and a diaphragm actuated valve element having open and closed positions respectively opening and closing. the inlet passageway to the flow of liquid therethrough to the outlet passageway and tank. A float operated valve element controls operation of the diaphragm actuated valve element and has a closed position when the tank is initially filled which precludes the flow of liquid into the tank thereafter, even when the tank becomes empty, until the liquid supply pressure is reduced to atmosphere.
