Hydropneumatic suspension for an automotive vehicle comprising anti-sagging valves

Abstract

Abstract 1. Motor vehicle hydropneumatic suspension of the type comprising a main actuator (1) fed at a pressure regulated by a high pressure pump, a suspension actuator (23a or 23b) cooperating with a hydropneumatic accumulator (24a or 24b) for each of the wheels of the vehicle, a height corrector (18a or 18b) for each of the axles and adapted for connecting the corresponding suspension actuators (23a or 23b) either to the main accumulator (1) or to exhaust depending on the axle load, characterized in that it comprises, for each axle, an anti-collapse valve (16a or 16b) inserted between the suspension actuators (23a or 23b) of this axle and the corresponding height corrector (18a or 18b), and means responsive to the pressure of the main accumulator (1) for opening and closing this valve.
