Abstract

L'invention a pour objet un ressort pneumatique comprenant un cylindre à fluide, un piston coulissant à l'intérieur du cylindre et dont la tige sort par une extrémité de ce cylindre, un ensemble de guidage et d'étanchéité de la tige de piston formant obturateur étanche aux fluides à une extrémité du cylindre, et un ensemble de fermeture étanche aux fluides à l'autre extrémité du cylindre. L'ensemble de fermeture se présente sous la forme d'un obturateur cylindrique présentant une gorge périphérique dans laquelle est logé un joint annulaire, un alésage borgne, dirigé radialement vers l'intérieur coupant la gorge juste vers l'intérieur dans le sens axial de celle-ci et des moyens de passage aux extrémités de l'obturateur communiquant avec ledit alésage borgne.
