Abstract
An hydro-pneumatic suspension assembly for vehicles comprises a pressure chamber in a combination with an hydraulic suspension unit of the self-levelling type. The unit incorporates a spool valve for maintaining the length of the unit at a predetermined value irrespective of the load. The spool valve is responsive to the position of a piston rod which carries the piston of the unit, and a damper, comprising a restricted passage, is incorporated to delay the response of the spool valve to movement of an assembly comprising the piston and the piston rod.
