ABSTRACT:
A pneumatic shock absorber for use in a suspension has a cylinder and a piston with a piston stem mounted in the cylinder for reciprocation, the piston stem and the cylinder being connected to different relatively movable parts of the suspension. A communication is established between the two chambers which the piston separates in the housing, which communication is controlled so as to determine the rate of flow of the pneumatic medium therethrough and thus the extent and speed of reciprocation of the piston relative to the housing. A valve arrangement controls the pressure of the pneumatic medium in the interior of the housing.
