摘要： A check valve made up of a substantially rigid portion and a substantially flexible membrane that is generally dome shaped. The substantially rigid portion includes one or more spokes that meet in the center of the rigid portion and one or more partial spokes extending part way to the center of the rigid portion. The dome shaped, substantially flexible membrane also includes one or more flexible spokes and one or more collapse zones. The completed check valve is made by connecting a center portion of the substantially rigid portion to a center portion of the dome shaped, substantially flexible membrane.

摘要： A backflow and strainer device is presented. The device is a unitary unit that prevents backflow of fluid gas in a compressor and prevents dirt particles and debris from entering the compressor, thereby damaging the components. A valve mechanism moves between an open position and a closed position to either allow or prevent fluid gas from flowing into the compressor. A mesh portion is disposed in the device to trap all dirt particles and debris to prevent them from entering the compressor. The valve mechanism responds to the higher and lower pressures associated with the operation and shutdown of compressors.

摘要： A valve seat and valve guard are coupled together, and form a chamber therebetween within which a valving plate moves. A stud secures the seat and guard together, and has a bore formed therewithin for receiving a headed piston. The piston has a projecting rod which engages the valving plate, and a pilot hole formed in the stud addresses a pressured fluid thereinto for moving the piston, causing the rod to move the plate laterally in the chamber. Apertures in the seat, guard and plate align, when pressured fluid enters the seat apertures, as the plate rises from the seat, and combines with the lateral movement to displace the plate diagonally in the chamber.

摘要： The invention contemplates an improved air flow sensor including a proximity switch which has a metal disk mounted with respect to the sensing face to be movable by air flow in the action zone of the magnetic field as between a position adjacent the sensing face to a position away from the face or visa versa whereby the switch oscillator is off and on respectively at the two extremes to provide an indication of the condition. The air flow sensor is shown herein in apparatus to calculate breathing rate, in object detection apparatus, and in vacuum lift apparatus.

摘要： A compressor discharge valve assembly including a valve seat, a valve cage, and an annular ring-type valve operating therebetween. The valve cage includes a recess into which the valve retracts when in an open position, or in an alternative embodiment, the valve cage includes a lip portion for shielding the valve. In either embodiment, a reduction in valve flutter and the noise, known as chatter, which results from valve flutter is realized. The valve in alternative embodiments also includes an annular dished portion oriented toward the valve seat for directing the flow of discharge gas smoothly from the compressor and thereby further reducing valve chatter.

摘要： A valve for automatically disconnecting a water supply from an outlet when water from another source is connected to the valve. The valve has two inlets: one connected to the city water supply and the other connected to the tank water supply. The check valve closes off the tank water supply automatically when water under pressure is connected to the city water supply. Thus, the water from the city water is prevented from entering the supply tank.

摘要： A plurality of concentric annular plates (1) are braced against a valve guard (2) by means of radially arranged spring-loaded bridges (5). The guided height (6) of the bridges (5) is at least equal to the maximum lifting height (7) of the annular plates (1) which abut against centering elements (8) of the bridges (5) and are guided by means of the bridges (5) relative to the valve guard (2) along the entire lift. A very simple guiding of the annular plates (1), which preferably impact against the valve guard (2) only via the bridges (5) and thus show a reduced tendency to sticking, is achieved particularly by constructing the annular plates (1) and/or bridges (5) from fiber-inforced plastic material.
