Hydropneumatic suspension with at least one piston cylinder unit - has one cylinder chamber connected to spring reservoir, with other compressible medium-filled chamber forming second spring reservoir

摘要

A hydropneumatic suspension system has at least one piston/cylinder unit (2), the piston (10) dividing the cylinder (8) into two pressure chambers. The first hydraulic fluid-filled pressure chamber (18) is connected to and acts against a first compressible medium-filled spring reservoir (4). The second pressure chamber (20) contains a compressible medium and forms a second spring reservoir. ADVANTAGE - Simple, more compact construction.
