    Abstract: An accumulator installed in the piping of equipment and temporarily accumulating a pressure in a pipe flow path or absorbing, by a pump, the pulsation of a fluid pressure generating in the piping, wherein a bladder (3) is formed in a laminated structure having, for example, a center elastic layer (321), gas shielding layers (322) on the outside thereof, external elastic layers (323) on the outside of the gas shielding layers and the center elastic layer (321), gas shielding layers (322), and external elastic layers (323) are formed of polyamide resin, and the gas shielding layers (322) are formed so that the bending elastic modulus thereof is higher than the bending elastic moduli of the center elastic layers (321) and external elastic layers (323), whereby the durability of the bladder (3) against a repeated bending and stretching operation in the low temperature environment of 0 DEG or below can be increased and the volume of cushion gas in a gas chamber can be effectively prevented from decreasing.

    Abstract: An ultra-sound testing device for gas pressure accumulators is used to test a predeterminable set position that can be taken by a movable separating element (20) inside an accumulator (10) that can be filled with gas and connected to a fluid circuit. The separating element (20) has at least one testing body associated with a visible mark (34) which indicates the set position of the separating element (20), and on the basis of which an ultra-sound testing device provided for the respective testing body can be set on the accumulator (10). This testing device allows a plurality of accumulators of the same type to be tested for their predeterminable gas pressure set value, which corresponds to the gas pre-filling pressure, by means of a single hand apparatus. This kind of test is economical and achieves reliable results.

    Abstract: The reservoir (10) has a cylinder (11) and a separating piston (13) arranged to slide therein. The piston separates a pressure medium storage chamber (15) from a gas chamber (14) in the cylinder (11). The separating piston (13) is sealed against the cylinder (11) by at least two rings (20 and 21) arranged at a distance apart axially on the periphery of the piston. Between the piston rings (20 and 21) is a collection chamber (22) from which opens a drilling (23) in the piston (13). The drilling (23) opens into the gas chamber (14) and can be closed off by a return valve blocking the passage from the gas chamber into the collection chamber (22). When the storage chamber (15) is emptied, pressurised gas and liquid conveyed with it from the gas chamber (14) into the collection chamber (22) are fed back into the gas chamber (14) via the drilling (23) on the opening of the return valve (27) as a result of being allowed to pass through the piston ring (20) on the gas chamber side. This lengthens the useful life of the pressure medium reservoir (10).

    Abstract: 液体膨張時における圧力変動吸収機構の部品点数を削減し、組立てを簡単にし、部品コストを低減させる。この目的を達成するため、アキュムレータは、ベローズキャップに設けられたシールホルダと、シールホルダによって保持されたプレート状のシールとを有する。シールホルダは内向きフランジ状の外周側係合部を備え、シールはシール本体の外周面に設けられるとともに外周側係合部に係合するゴム状弾性体よりなる外向き突起状の内周側係合部を備える。液室閉塞状態で液室内の液体が膨張したとき、外周側係合部が内周側係合部を弾性変形させつつシールはその両面における受圧面積の差により着座面に着座したままでベローズキャップが液圧およびガス圧が均衡する位置まで移動する。

    Abstract: PURPOSE:To prevent reduction in the airtight characteristics due to uneven wear of a piston ring by slidably engaging the common end part of a piston rod in a cylindrical hole shaped on the back face of a piston. CONSTITUTION:The common end part 6a of a piston rod 6 is slidably engaged in a cylindrical hole 1a shaped on the back face of a piston 1. Even if the piston rod 6 is inclined because springs 7 and 8 which are external engaged on the rod 6 are inclined due to their own weights, the piston 1 will then be subjected to only a minimal bending moment produced when the rod 6 is inclined. Reduction in airtightness inside a pressure accumulator chamber 3 due to uneven wear of the piston ring 5 can be prevented.

    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.
