摘要: A hydropneumatic system (51) for suspensions of vehicle wheel assemblies is provided, for each suspension, with a respective hydropneumatic cylinder (1) having a first and a second body (10,11), which can move axially relative to each other and define respective chambers (14,15), axially separated from each other via a piston element (30); the latter is coupled in a fluid-tight manner to the second body (11) and floats between two stroke end positions in response to the pressures in the two chambers (14,15); the two chambers (14,15) of each hydropneumatic cylinder (1) communicate respectively with a hydraulic supply line (52) and with a pneumatic supply line (57); the system (51) further has a pressurization device which sets the pressure in the pneumatic supply line (57) to a value at least equal to the pressure in the hydraulic supply line (52).
