摘要： A valve comprises a housing including a first chamber, a second chamber, and a neutral chamber. In addition, the valve comprises a stem disposed within the housing. Further, the valve comprises a first valve member at least partially disposed in the first chamber and connected to the stem and a second valve member at least partially disposed in the second chamber and connected to the stem. The first valve member has a closed position seated in a first annular valve seat and an open position spaced apart from the first valve seat. The second valve member has a closed position seated in a second annular valve seat and an open position spaced apart from the second valve seat. Moreover, the valve comprises a biasing member configured to bias the second valve member to the closed position and the first valve member to the open position.

摘要： A system for a pneumatically-powered vitrectomy machine includes an output port, a venting valve, a venting manifold, a pressure transducer, and a controller. The output port provides pressurized gas to a vitrectomy probe. The venting valve is located close to the output port. The venting manifold fluidly connects the venting valve to a venting port. The venting port vents pressurized gas from the venting manifold. The pressure transducer is located near the output port. The pressure transducer is configured to read a pressure of a gas near the output port. The controller is adapted to receive information about the pressure and activate the venting valve. When the information received from the pressure transducer indicates a fault condition, the controller directs the venting valve to open.

摘要： A device for putting in solution a powdery concentrate includes a liquid supply pipe (10), an extraction pipe (30) with a valve (31), and a transfer pipe (40) connected to a junction point, the transfer pipe being for connecting to a receptacle (50) containing the concentrate. The junction point is in the constriction of a venturi tube (20), the supply pipe (10) being connected to the convergent chamber (21) and the extraction pipe (30) to the divergent chamber (22). If the valve (31) is closed, the liquid leaves the venturi tube through the vacuum tapping to enter the receptacle. When the valve (31) is opened, the liquid leaves the venturi tube through the divergence chamber, causing a pressure drop in the vacuum tapping. The saturated liquid contained in the receptacle is then sucked and entrained by the liquid passing through the venturi.

摘要： An apparatus is provided and may include a control valve that moves a pressure-responsive unloader valve between a first position permitting flow through a valve plate and into a compression mechanism and a second position restricting flow through the valve plate and into the compression mechanism. The control valve may include at least one pressure-responsive valve member movable between a first state supplying discharge-pressure gas to the unloader valve to urge the unloader valve into one of the first position and the second position and a second state venting the discharge-pressure gas from the unloader valve to move the unloader valve into the other of the first position and the second position.

摘要： A one piece double membrane diaphragm including an upper (308) and lower diaphragm membrane (310) joined together by a central section (312) is provided. The upper diaphragm membrane (308) seals against a top sealing surface (222) when the diaphragm is in a first position. The lower diaphragm membrane (310) seals against a bottom sealing surface (224) when the diaphragm is in a second position. The diaphragm may also be made from a resilient material and shaped in such a way as to create a spring force holding the diaphragm into a default position in the valve.
