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 vehicle brake system has a gas pressure accumulator (10) comprising a housing (12), the interior of which is divided by metal bellows (16) into a gas-sensed gas chamber (20) and a fluid chamber (22). Via a feed line (24) a fluid may be supplied under pressure to and removed from the fluid chamber (22), wherein provided between the fluid chamber (22) and the feed line (24) is a valve arrangement (74), which closes when the pressure in the feed line (24) drops below a minimum value and opens when the pressure exceeds the minimum value. To increase the operational reliability of the gas pressure accumulator (10), the valve arrangement (74) closes when the pressure in the feed line (24) exceeds a maximum value and opens when the pressure drops below the maximum value.

Abstract: For a hydraulically actuated device a hydraulic power cylinder with an actuator slidably received for reciprocation within the cylinder and a piston slidably received for reciprocation within a sleeve of the actuator and defining a gas chamber on one side of the piston and a hydraulic fluid chamber on the other side of the piston so that the maximum pressure in the hydraulic fluid chamber is limited as a function of the force of compressed gas in the gas chamber acting on the piston. In this way, the maximum system pressure is a function of and substantially corresponds to the pressure of the compressed gas within the gas chamber and acting on the piston. Desirably, the pressure of the compressed gas in the gas chamber can be readily changed to change the maximum hydraulic fluid pressure.

Abstract: The invention pertains to a hydropneumatic suspension system, in particular for motor vehicles, with at least one hydraulic strut (2) that acts upon at least one hydropneumatic piston-type accumulator (6) during deflection and rebound movements. The piston-type accumulator (6) has a separating piston (22) that separates the hydraulic accumulator chamber (24) from a spring chamber (26) containing a compressible medium, in particular a gas. A hydraulic pressure (P.sub.h) acts upon the separating piston (22) from the side of the accumulator chamber (24) and a pneumatic pressure (p.sub.p) acts upon the separating piston from the side of the spring chamber (26), with at least one supplementary spring force (F.sub.F ;F.sub.F1 ;F.sub.F2) acting upon the separating piston (22) of the piston-type accumulator (6) in addition to the forces (F.sub.h,F.sub.p) resulting from charging the separating piston (22) with the hydraulic pressure (P.sub.h) and the pneumatic pressure (p.sub.p). This supplementary spring force is generated by at least one spring element (28;34;36) that is arranged outside of the spring chamber (26).
