    摘要： An apparatus for allowing the repetitive oscillation of pressure in a container or vessel having a finite volume. The apparatus comprises a valve having first opening, a valve enclosure having a second opening, and a first tension device. In some embodiments the apparatus can have a chamber capable of oscillating in volume. The oscillation of the chamber volume causes a decrease in the pressure of the container. As the pressure of the space or container decreases, two openings of the apparatus become more proximate. Eventually the openings partially overlap, allowing a gas, or fluid, to enter the container, increasing pressure of the space or container. As a result of the pressure increase, the first opening and second opening become less proximate by a force of the first tension device. The apparatus can allow the container to approach substantially perfect vacuum and rise toward atmospheric pressure.

    摘要： An automatic valve including a valve seat having first gas flow passages extending there through and a valve guard having second gas flow passages extending there through. The valve further comprises at least one shutter member movably arranged between the valve guard and the valve seat, at least one set of spring members biasing the at least one shutter member towards a closed position in sealing engagement with the valve seat to close the first gas flow passages, and at least one spring holder ring provided with a plurality of spring retention seats. Each spring member of the set of spring members is partially housed in a respective spring pocket formed in the valve guard and retained in a respective one of the spring retention seat.

    摘要： A differential pressure valve is disclosed, comprising: a valve body, the valve body having at least one flow inlet and one flow outlet; at least one shutter, the shutter being movable between an open position and a closed position under a differential pressure across the valve; a flow passage from the flow inlet to the flow outlet; at least one biasing member configured to bias the shutter towards a closed position so as to block the flow passage through the flow inlet. The biasing member comprises at least two springs arranged in parallel, one of the springs having at least one resonance frequency different from at least one resonance frequency of the other of the two springs.

    摘要： Simple refinishing of the valve seat 3 of an annular valve 1 is made possible, which has a plurality of ring guide studs 15 arranged radially and separated in circumferential direction and projecting from said valve seat 3 to guide sealing rings 5 in radial and axial direction, whereby a recess 18 is provided in the valve seat 3 extending in circumferential direction between to ring guide studs 15 lying at the same radius. No cross piece negatively influencing the outgoing flow must remain between the sealing surfaces 17 in the area of the recess 18 during refinishing of said sealing surfaces 17 of the valve seat 3.

    摘要： A check valve responsive to low cracking pressures includes first and second body portions defining a valve chamber. An inlet and outlet passage communicate with the valve chamber while a valve element received therein moves between open and closed positions responsive to pressure differentials. A stop member welded to the valve body is adapted to limit the opening movement of the valve element. An axially raised central portion of the stop member abuttingly engages the valve element to limit its opening movement yet permit fluid flow around the valve element to plural openings defined in a peripheral region of the stop member. A guide member is interposed between the stop member and valve element to urge a seal member disposed on one face of the valve element toward a seated, closed position.
