PCT No. PCT/EP93/02779 Sec. 371 Date Apr. 10, 1995 Sec. 102(e) Date Apr. 10, 1995 PCT Filed Oct. 11, 1993 PCT Pub. No. WO94/08808 PCT Pub. Date Apr. 28, 1994The 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 (Ph) acts upon the separating piston (22) from the side of the accumulator chamber (24) and a pneumatic pressure (pp) acts upon the separating piston from the side of the spring chamber (26), with at least one supplementary spring force (FF;FF1;FF2) acting upon the separating piston (22) of the piston-type accumulator (6) in addition to the forces (Fh,Fp) resulting from charging the separating piston (22) with the hydraulic pressure (Ph) and the pneumatic pressure (pp). This supplementary spring force is generated by at least one spring element (28;34;36) that is arranged outside of the spring chamber (26).
