Abstract

Cette suspension est caractérisée en ce qu'elle comprend un socle 20 constitué par un corps creux divisé intérieurement en une première et une seconde chambre disposées côte à côte et dont les parties inférieures communiquent entre elles au moyen d'au moins un conduit, la première chambre ayant, au moins dans sa partie supérieure, la forme d'un cylindre d'axe vertical dans lequel coulisse un piston 30 qui fait saillie à la partie supérieure de ce socle 2 et qui sert de montant de support pour le siège 10, la première chambre étant complètement remplie d'un liquide, lequel ne remplit que partiellement la seconde chambre, cette seconde chambre étant associée à une pompe à main pour l'introduction d'air sous pression, à partir de l'atmosphère, au-dessus de ce liquide, et à un obturateur à main permettant d'évacuer à volonte de l'air vers l'atmosphère.This suspension is characterized in that it comprises a base 20 constituted by a hollow body divided internally into a first and a second chamber arranged side by side and whose lower parts communicate with each other by means of at least one duct, the first chamber having, at least in its upper part, the shape of a cylinder with a vertical axis in which slides a piston 30 which projects from the upper part of this base 2 and which serves as a support post for the seat 10, the first chamber being completely filled with a liquid, which only partially fills the second chamber, this second chamber being associated with a hand pump for the introduction of pressurized air, from the atmosphere, above this liquid, and to a hand shutter allowing air to be evacuated at will to the atmosphere.
