The shock absorber is characterized by the fact that it comprises a rod (1) sliding in a cylinder (2) through a piston (3) to determine at least two variable-volume chambers (4,6), ports (40,41) for placing the two chambers in communication, one of the two chambers (4) comprising first elastic fluid

The shock absorber is characterized by the fact that it comprises a rod (1) sliding in a cylinder (2) through a piston (3) to determine at least two variable-volume chambers (4,6), ports (40,41) for placing the two chambers in communication, one of the two chambers (4) comprising first elastic fluid (44) at a first given pressure, the other chamber (6) comprising second elastic fluid (10) at a second given pressure, controllable according to at least one parameter, corresponding to a force to be absorbed.

A shock absorber comprising: a cylinder having an open end and a closed end; a hollow rod having a piston at one end slidable in said cylinder; a first chamber in said rod; a second chamber between said rod and said cylinder; a third chamber in said cylinder between said piston and said closed end of said cylinder containing an incompressible fluid; port means in said piston connecting said first and third chambers and said second and third chambers; said third chamber comprising: a first section defined by a transverse wall in said third chamber and by said piston, said transverse wall including pressure-relieving means; a second section formed by said transverse wall and a separating piston slidable between said transverse wall and a projection in said cylinder located at the proximity of said closed end thereof; a third section defined by said separating piston and a movable member slidable between said projection and said closed end of said cylinder; and a fourth section between said movable member and said closed end, said fourth section including a nozzle extending from said closed end through said movable member for supplying a compressible fluid through said nozzle to said third section, and an orifice in said closed end for supplying an incompressible fluid therethrough thereby forming a jack chamber; said first chamber containing first elastic means at a first given pressure; said third section containing second elastic means at a second given pressure; and said second elastic means being controlled by movement of said movable member according to at least one parameter corresponding to the performance of said shock absorber.
