摘要： A gas flow valve having pneumatic vibration dampening device to reduce the vibrations created by the flow of gas through the gas valve. The gas valve includes a gas flow conduit that terminates at a discharge opening. A valve member is movably positioned relative to the discharge opening and allows gas flow in a flow condition and prevents the flow of gas in a seated position. The valve member includes a gas passage formed within the valve member. At least one flexible membrane is mounted to the valve member and surrounds an outlet opening of the gas passage. The flexible membrane is inflated as the flow of gas within the gas flow conduit increases such that the flexible membrane contacts an inner surface of a stabilizing conduit. The interaction between the flexible membrane and the stabilizing conduit reduces the vibrations created by the flow of gas past the valve member.

摘要： A fuel pump module includes a reservoir configured to hold a supply of fuel. The reservoir includes a fuel passageway and defines a first seat on a first side of the fuel passageway and a second seat on a second side of the fuel passageway. The module also includes a seal configured to be seated on the first and second seats to substantially seal the fuel passageway, and a weight biasing the seal toward the first and second seats by contacting the seal only at a location between the first and second seats. A gap may be defined between the weight and the seal, allowing fuel to enter the gap and further bias the seal toward the seats.

摘要： A non-return valve has a valve housing with a flow channel having a vertical channel section, an inlet aperture, an outlet aperture and a blocking device closing the flow channel. The blocking device comprises a valve seat surrounding the outlet aperture and a valve disc movable between an open position and a closed position. The valve disc is guided in the valve housing via a guide surface on its outer circumference, and comprises flow apertures radially outside its sealing surface. The valve disc possesses a diameter that becomes smaller towards the valve seat, forming an inclined external surface. Flow apertures start from the inclined external surface and converge in the direction facing away from the sealing surface, and are disposed in a uniform distribution over the circumference of the valve disc.

摘要： A pressure regulating valve for pressure cookers comprises a tubular projection (1) protruding from a cooker lid (2) and on which a needle (4) is poised, that is mounted to the bottom of an inverted cup shaped cylindrical body (6) provided with an external upper threaded projection (7) on which a head (8) is screwed. Steam escape openings (9) and a lower aperture are surrounded by an internal rim (10) and by an external ferrule (11). The rim is screwed on the end outside thread of the tubular projection (1), and the ferrule supports two selectively used weights, bottom (14) and top (15) defining together a spherical shape in the present device. The cup shaped piece (6) is provided with internal longitudinal channels (17) at the bottom of which there are corresponding steam escaping openings (9). Top weight (15) is calotte shaped and defines a chamber (21) with openings (22) to act as a jet breaker for the escaping steam, and head ( 8) has blocking projections (23) for the weights that can be aligned in relation to the longitudinal grooves (25 and 26) of the bottom of the weights for removal of the latter.

摘要： A relief valve assembly for pressure cookers in which the valve port is controlled by a predetermined weight. A skirt portion forming part of the mass of the weight surrounds the valve port so forming a chamber. The skirt portion has an opening in it such that gas entering the chamber from the pressure cooker via the valve port can escape to the atmosphere in a predetemined direction, e.g. away from a hand grip portion.

摘要： A low trauma, reversible flow pumping system is disclosed which is useful for transfer of biological fluids containing fragile components such as cells. The pumping system comprises a length of collapsible and flexible tubing in fluid communication at each end with a two-way, gravity actuated check valve means having a self-centering, vertically slidable weight member for directional regulation of fluid flow. Said tubing is sealingly enclosed within a hydraulic fluid containing chamber which is in fluid communication with oscillatory pressure providing means to cause alternate expansion and contraction of said tubing.
