    • An active suspension system for a vehicle including at least one fluid operated ram (14) having a cylinder (52) and a main piston (54) mounted therein for reciprocating movement, control means for controlling an equilibrium position of the piston (54) in the ram (14) in response to lateral acceleration of the vehicle in order to counter the effects of body roll of the vehicle, and wherein the ram (14) includes shock absorbing means (70) for permitting rapid movement of the piston (54) from the equilibrium position when operating fluid in the ram (14) is subjected to transient increases in pressure. For each ram (14), first and second working chambers (65, 67) are defined in the cylinder (52) on opposite sides of the piston (54) and the piston (54) includes at least one damping passage therethrough and valve means to control flow of operating fluid through said damping passage when the fluid in one or the other of the working chambers (65, 67) is subjected to transient increases in pressure.

    • Shock absorber device (2) comprising a shock absorber (6) combined with an air spring (8), which shock absorber device is arranged for active suspension/shock absorbing in a wheel suspension of a vehicle. The shock absorber (6) is surrounded by the air spring (8), and in the annular interspace (12) between the shock absorber and the air spring there is arranged a piston and cylinder device (10) likewise surrounding the shock absorber and which on the inside is connected to the shock absorber (6) and on its outside is connected to the air spring (8). The piston of the piston and cylinder device (10) is an annular piston which via an axial extension part (32) is connected to a stabilizer joined to the wheel suspension.
