A shock absorber for controlling the height of vehicles, comprising a cylinder (1), a shock absorber piston (2) including a piston rod (3) in a known manner being slidably mounted in the cylinder and having an end opposite to the piston extending sealingly through a first end (5) of the cylinder, a second end of which is closed, and a shock absorber spring (10). Characterizing is that the shock absorber spring (10) is arranged between the shock absorber piston (2) and a separating piston (4) located at an end of the cylinder (1), the separating piston (4) being sealingly slidable in relation to the cylinder wall and, together with the end of the cylinder, forming a closed control chamber (6), that a gas spring (8) known per se is connected to the control chamber (6) via (7) an shut-off valve (9) and that, when a certain load is acting on the piston rod (3) and when the shut-off valve (9) is open, the pressure from the gas spring (8) acting on the separating piston (4) is higher than the pressure from the spring (10) on the separating piston (4), and when a larger load is acting on the piston (3) and thereby on the spring (10) acting against the separating piston (4), the pressure in the control chamber (6) is higher than the pressure in the gas spring (8).
