1. A suspension system comprising:
a body provided with a cylindrical cavity in which there is slidably mounted a piston that divides the cylindrical cavity into two working chambers: a lower chamber and an upper chamber, each of which receives a gas, the piston being connected to a piston rod protruding from the cylindrical cavity through a sealing ring; an external tube, the body sliding within this external tube, said external tube being engaged around the piston rod and at its free end comprising a lower plug to which an end of the piston rod is secured, the space between the lower plug of the external tube and the sealing ring determining within the external tube a third chamber filled with gas by a preload valve; and a single filling valve to fill the lower and upper chambers, and a gas transfer element to transfer gas from one of the two working chambers to the other, according to predetermined conditions, and wherein the gas transfer element is a lateral chamber formed in an internal wall of the body, said lateral chamber being configured to come successively in relation to the lower chamber and the upper chamber depending on a position of the piston in the body. |
