Abstract
A hydro-pneumatic suspension system adapted to be connected to first and second sides of a vehicle for leveling the vehicle in a side-to-side direction includes first and second absorbers, a pump and a gas spring element. Each of the first and second absorbers includes a piston rod provided with a piston for slidingly engaging a cylinder and an actuating chamber for an actuating liquid formed between the cylinder and the piston. The pump and the gas spring elements are connected to the actuating chamber of the first and second absorbers to control the flow of the actuating liquid. The pump and the gas spring element are independent from the first and second absorbers.
