Abstract

Provided is a continuous hydraulic suspension system which has, in each front and rear valve block (25, 26), an Energy Management Valve (EMV) (27, 28) and Check Valves (CV) (29, 30, 31, 32) to provide re-circulation of oil in the resistive mode. The system allows reduced energy consumption during non-motoring modes, and enables a smaller capacity pump and/or an electric motor pump to be used.
