Abstract: A piston storage device has a piston (13) with two collars (15, 16) separated by a central necked portion (14). A sealing means is arranged in both piston collars. The sealing means facing the gas chamber (18) is designed in such a manner that pressurized gas can enter the gas chamber (18) via a bore (32) through the wall of the housing, via the sealing means which is then adjusted accordingly. When the pressure in the gas chamber is as high as the pressure of the gas supply source, the sealing means returns to its original position, this sealing the gas chamber from the fluid chamber (19).

Abstract: The pressure vessel comprises an accumulator (10) having a piston (16) disposed in a bore (14). The piston (16) has gas under pressure on one side thereof maintained within the bore (14) by means of a multiple seal in an opening (26) having first (28), second (32), and third diameter (36) sections. The multiple seal includes a fill screw (40) threadedly engaging the second diameter section (32) of the opening (26), the fill screw (40) having a conical surface (46) sealingly engaging a seat (31) between the first diameter (28) and second diameter (32) sections of the opening. A cap screw (70) is threadedly received within the third diameter section (36) and compresses an O-ring (60) between the cap screw (70) and housing (12). The cap screw (70) has an annular rib (77) which bites into a shoulder (34) of the body (12) to provide an additional seal for maintaining the gas under pressure within the bore (14).

Abstract: The pressure accumulator (10) comprises a cylindrical housing (12) having a bore (14) with a piston received slidably therein. The piston (30) has an H-shaped cross section and includes a reduced diameter portion (34) extending longitudinally along the piston (30), and a sealing device (36, 38) disposed at each end of the reduced diameter portion (34). A cylindrical sleeve (44) is received in the reduced diameter portion (34) such that each end of the sleeve (44) abuts a respective sealing device (36, 38). The housing (12) has an exterior circumferential groove (20) with an 0-ring (26) therein, and a radial opening (22) extending between the circumferential groove (20) and bore (14). Alternatively, the piston (30) may have a longitudinal opening (61) extending from one side of the piston to grooves (63, 64) at the other end (32), the grooves (63, 64) receiving a ring (72) which is subjected to fluid pressure transmitted through the longitudinal opening (61) and expanded radially outwardly against an angled portion (73) of a force-transmitting member (74) which moves longitudinally against seals (76, 77) disposed in one of the grooves (63, 64).

Abstract: The invention concerns a hydraulic accumulator comprising a piston (3) capable of moving in an accumulator housing (1) in the axial direction thereof, and separating a gas side (5) from a liquid side (7) of the accumulator housing (1). Guide elements (9, 17) designed to co-operate with the accumulator housing wall (1), as well as at least one sealing element (15) are arranged at the periphery of said piston. The sealing element is arranged offset in the axial direction relative to the guide elements (9, 17), in said peripheral part of the piston (3) located between said guide elements. In the piston (3) is a pressure compensating channel (19) which forms, at the piston periphery, a liquid flow path between the liquid side (7) and a space (2) located between the guide element (17) nearest to the liquid side (7) and the sealing element immediately next in the axial direction. A device (25) reducing the cross-section of the passage of the pressure compensating channel (19) is located therein.

Abstract: The invention relates to a hydraulic accumulator, especially a piston-type accumulator, comprising an accumulator housing (10) as well as at least one gas chamber (12) that is arranged therein and a fluid chamber (14) which are separated from each other via a separating element (16), particularly in the form of a piston. One free end of the accumulator housing (10) is sealed via a valve block (24) that is provided with a ball valve (28) which opens or blocks a fluid-guiding path (30) from the interior of the accumulator housing (10) towards the outside in the open position or closed position thereof such that the ball valve forms an integral part of the accumulator housing via the valve block and is thus accommodated in a compact manner within the hydraulic accumulator solution, also resulting in a reduction of the free fluid paths and therefore a reduction of tubing.

Abstract: The invention relates to a method for producing piston-type accumulators comprising an accumulator housing (10) and a separating piston which can be displaced in a longitudinal direction inside the accumulator housing (10) and separates two working spaces located therein. The end faces of the accumulator housing are sealed by means of one respective cover part (20). Previously known production methods are further improved due to the fact that the cover part (20) is fixed on one side (40) thereof via the free longitudinal edge (32) of the accumulator housing (10), which is displaced towards the cover part (20) in order to do so, such that a functionally and positionally secure connection of a cover part is ensured within the housing of a piston-type accumulator without using standard threaded connections.
