ABSTRACT:
An hydro-pneumatic suspension device comprises a pressure chamber and a working chamber which are separated from each other by a first diaphragm. The pressure chamber contains a trapped volume of gas under pressure for supporting the load on a wheel or axle, the working chamber contains a volume of liquid under pressure which is trapped between the first diaphragm, and oppositely acting one-way valves or restrictors are provided for damping liquid flow in the working chamber. The side of the second diaphragm remote from the working chamber is subjected to a supply of liquid of which the pressure can be altered to compensate for changes in pressure in the pressure chamber due to changes in the loading on a vehicle.
