Abstract: An energy storage device a first member and a second member that is slidably engaged with the first member. There are at least two seals that slidably seal the first member to the second member and define a cavity therebetween that varies in volume with relative movement between the first member and the second member. The first member is biased toward the second member in a direction that resisted increases in volume of the cavity.

Abstract: A hydraulic fluid reservoir (10, 10', 10'', 10''') comprises a body (12, 12', 12'' 12''') defining a variable volume chamber having one end portion movable with the level of fluid in the chamber. A biasing member (18, 18', 18'', 18''') acting on a traction rod (16, 16', 16'', 16''') extending from the movable end portion restrains movement thereof under fluid pressure. The fluid pressure in the variable volume chamber advantageously counterbalances the force of reaction in the biasing member (18, 18', 18'', 18''').

Abstract: A combined oil tank and oil accumulator vessel (1) having an internal chamber, and a moveable spring-loaded barrier (3) within the internal chamber defining a low pressure oil tank portion (10) and a high pressure accumulator portion (14) separated by the moveable barrier (3). The combined oil tank/accumulator provides the advantages of more consistent oil flow supply as a result of the integral accumulator, but with reduced weight, reduced oil volume requirements, and constant oil levels when compared with conventional external accumulators.

Abstract: The invention relates to a vehicle braking system comprising a gas hydraulic accumulator (10) with a housing (12), whose interior is divided by metal bellows (16) into a gas-filled gas chamber (20) and a fluid chamber (22). A pressurised fluid can be supplied to and conveyed from said fluid chamber (22) via a supply line (24). A valve assembly (74) is provided between the fluid chamber (22) and the supply line (24), which closes if the pressure in the supply line (24) falls below a minimum value and opens if the pressure exceeds said minimum value. In to order to increase the operating security of the gas hydraulic accumulator (10), the valve assembly (74) closes if the pressure in the supply line (24) exceeds a maximum value and opens if the pressure falls below said maximum value.

Abstract: The invention pertains to a hydropneumatic suspension system, in particular for motor vehicles, with at least one hydraulic shock-absorbing strut unit (2) which in its cushioning movements uses an hydraulic medium to impact at least one hydropneumatic piston-type accumulator (6). The piston-type accumulator (6) has a separator piston (22) that separates an hydraulic accumulator (24) from a spring chamber (26) containing a compressible medium, especially a gas. The separator piston (22) is acted upon both by an hydraulic pressure (Ph) coming from the accumulator (24) and a pneumatic pressure (Pp) from the spring chamber (26), and, in addition to the forces (Fh, Fp) resulting from the action of the hydraulic pressure (Ph) and the pneumatic pressure (Pp) on the separator piston (22), at least one additional spring force (FF; FF1; FF2) acts upon the separator piston (22) of the piston-type accumulator (6). This additional spring force is produced by at least one spring element (28; 34; 36) mounted outside the spring chamber (26).

Abstract: The pressure-producing device (10) comprises a housing (30) which is slidable relative to a stationary piston (60), the housing (30) movable within a substantially blind bore (12) to effect the pressurization of fluid. A body (14) containing the blind bore (12) includes a retention member (22) located adjacent an end opening (16) of the blind bore (12). The pressure-producing device (10) is received within the blind bore (12) wherein a closed end (32) with a seal (44) thereabout defines with an end of the blind bore (12) a pressurizing chamber (50). The piston (60) is received slidably and sealingly within an interior opening (39) of the housing (30) and extends from an end opening (34) thereof in order to engage the retention member (22) and position stationarily the piston (60). The housing (30) and piston (60) are displaced away from one another by a pressurized medium within the housing (30). The piston's (60) stationary position enables the housing (30) to slide within the blind bore (12) and effect the pressurization of fluid received within the chamber (50).

Abstract: The combination accumulator and variable volume sump (50) comprises a housing (52) having therein a stepped bore (56). A pair of U-shaped piston (60, 80) are disposed within the stepped bore (56), the first piston comprising an accumulator piston (60) and defining with the housing (52) and stepped bore (56) a first chamber (70) containing therein pressurized medium. The second piston (80) defines with the housing (52) and stepped bore (56) a second chamber (90) containing therein pressurized fluid. Open ends of the U-shaped pistons (60, 80) are received one within another, and a spring (95) is disposed between interior openings (62, 82) of the pistons (60, 80) to bias them apart. The housing (52) has a pair of openings (54, 59) for communicating pressurized fluid, one opening (54) communicating with the second chamber (90) and the other opening (59) communicating with the stepped bore (56) in order to communicate pressurized fluid to the first piston (60). Displacement of the first piston (60) along the stepped bore (56) results in a corresponding increased displacement of the second piston (80) relative to the housing (52).
