A closure member (118) cooperates with the housing (98) to substantially seal the cavity (96). A pre-loaded elastomeric member (112) is disposed within the cavity (96) and is compressible with increasing hydraulic fluid pressure to attenuate short duration pressure pulses therein. The elastomeric member (112) is preferably enclosed within a rigid relatively porous member (106) which, in combination, with the elastomeric member (112), substantially fills the entire volume of the cavity (96) and permits pressurized fluid to act on substantially the entire outer surface of the elastomeric member (112) to minimize the internal friction and hysterisis losses and provides the structure, along with the closure member (118) to pre-load the elastomeric member (112).

    Abstract: The invention relates to an electronically controllable brake system for a motor vehicle with a cylinder/piston arrangement provided with brake fluid. Operation of a brake pedal causes said arrangement to supply brake fluid acting on a vehicle brake. The cylinder/piston arrangement can be connected to a pump arrangement and a pressure accumulator which has a housing (10) having a fluid connection (12) for fluid flowing in or out of the housing, and a spring arrangement (30a, 30b). Brake fluid flowing in through the fluid connection (12) acts against the force of said spring arrangement, at least one part (30a) of the spring arrangement being formed by at least one part of the housing wall.

    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: 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).
