    Abstract: PURPOSE:To improve performance of an accumulator by disposing a support for a separating member, which is formed by laminating a plurality of wire nets at random on a port for delivering and admitting a fluid to a chamber where the separating member is expanded. CONSTITUTION:A support 13 for a separating member, whichis formed by lamin ating a plurality of wire nets n1-n3 at random is disposed at a port 8 for delivering and admitting a fluid to a chamber (b) where a separating member 9 is expanded. Thus, the support 13 can have substantially uniform through holes on the whole surface thereof, and flow resistance is diminished to exhibit high performance and attain high operation performance as a transfer barrier. Furthermore, the through holes are fine and uniform, so that the separating member 9 is kept from being pushed to completely protect the separating member 9.

    Abstract: PURPOSE:To keep the fluid pressure in a pressure fluid chamber high all the time and prevent the leakage of gas by providing in a through path, which connects the pressure fluid chamber of a piston with a fluid chamber, a check valve which allows one-way flow of fluid from the fluid chamber to the pressure fluid chamber. CONSTITUTION:A chamber 27 in a closed-end round hole is connected to a pressure fluid chamber 24 by use of a through hole 28, in which a working fluid is contained. The chamber 27 is connected to a through path 29, and a check valve consisting of a ball valve 31 and a compression coil spring 32 is set on a tapered valve seat 30 formed at the inlet of the chamber 27. In this way, an arrangement is made so that the fluid pressure in a pressure fluid chamber 17 is applied to the pressure fluid chamber 24 through the check valve having a ball valve 52, and therefore, the fluid pressure in the pressure fluid chamber 24 is kept high, reducing the pressure gradient; thus the leakage of gas can be prevented.

    Abstract: PURPOSE:To prevent a rapid closing of a poppet valve caused by a dynamic pressure by a method wherein liquid is filled in a liquid chamber in a bearing cylinder. CONSTITUTION:When a poppet valve 5 is opened, a large diameter upper part (c) of a valve shaft 6 is positioned above a liquid chamber 11 at a bearing cylinder 8 and liquid is immersed from a sliding clearance between the valve shaft 6 and the bearing cylinder 8 and filled in the liquid chamber 11. When the liquid in the main body 1 of a container is discharged from a supplying and discharging port 4 at a speed more than 25m/sec, the poppet valve 5 is rapidly closed. However, the liquid filled in the liquid chamber 11 is compressed by the large diameter upper part (c) of the fast descending valve shaft 6, so that the liquid is compressed to increase the pressure and to resist against the descending of the valve shaft 6 and the opened valve condition is kept. However, when the slow discharging of the liquid is kept, the liquid in the liquid chamber 11 is discharged from the sliding clearance between the valve shaft 6 and the bearing cylinder 8 to close the poppet valve 5.

    Abstract: A replaceable antenna assembly for use with a piston accumulator configured for supplying fluid to a hydraulic cylinder is provided. The antenna assembly includes a hollow manifold for flow of fluid and an antenna connected into or onto the manifold for emitting and receiving electromagnetic waves. The hollow manifold is connectable to and configured to be in fluid communication with both the piston accumulator at one end and a pressure line at the other end. The pressure line is connectable to an external high pressure gas bank. The antenna assembly further includes at least one first bore for transferring signals to and from the antenna and at least two fluid channels symmetrically displaced around the circumference of the antenna, thereby ensuring that most of, or all, fluid flows on the radial outside of the antenna during use.

    Abstract: A hydraulic accumulator, preferably a membrane accumulator, in particular for damping pulsations in fluid circuits, includes an accumulator housing (12) with at least one inlet (14) and an outlet (16) for the fluid for damping. A separating element (18), preferably in the form of a membrane, separates a gas reservoir (20) from a fluid chamber (22) within the accumulator housing (12). A hydraulic accumulator with high working capacity of high reliability which little space requirement despite high accumulation capacity for the working gas in the gas reservoir (20) can be achieved. A support device (24) within the accumulator housing (12), extends within the gas reservoir (20) and forms a possible support for the separating element (18). The gas reservoir (20) of the accumulator housing (12) is sufficiently large in dimension that the total necessary gas volume is retained within the accumulator housing (12) itself. The membrane is formed from an elastic material, in particular a rubber material of polytetrafluoroethylene or compounds thereof, as a gas barrier layer.

    Abstract: An accumulator in which a pressure sealed chamber and a pressure flow-in chamber are formed by an operation member including a metallic bellows provided within a housing constituted by a gas end cover and a bottomed tubular shell, wherein a cross sectional inner outline of a peripheral edge portion of the gas end cover is an oval shape which is concave to the pressure sealed chamber side, and a dead space is not formed, so that a capacity of a volume adjusting spacer is reduced by eliminating a dead space, a working step is reduced by simplifying a shape of the gas end cover, and a margin of welding penetration depth is increased by thickening of a backing metal portion.
