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 pressure fluid accumulator with a housing having its interior subdivided by a media-separating element into two chambers, the first chamber being filled with a gas and the second chamber being filled with a liquid, and wherein in a hydraulic port a bottom valve is provided which permits filling the second chamber with liquid and prevents complete evacuation of the second chamber, and the valve's closure member is operable by the media-separating element. In order to prevent, especially at low temperatures and high viscosity of the pressure fluid, damage of the media-separating element caused by a high differential pressure, a device is provided between the media-separating element and the bottom valve.

Abstract: Accumulator device for a hydraulic installation which includes an interior membrane, the membrane forming a fluid-accumulation cavity. It is characterised in that the membrane includes a fold which forms two sections, a first section from the wall of the cylindrical body to the fold and a second section from the fold to the moving support element, with the fold zone moving as the moving support element moves. It allows sufficient volumes of water accumulation to space apart the starting and stopping of the electrically-driven pump, but with small diameters of the membrane's moving support element.

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).
