Abstract
L'invention concerne un ressort pneumatique télescopique Ressort caractérisé en ce qu'avant le canal de transfert 18 est interposé un plan d'étanchéité E-E, de sorte qu'une fois que les éléments télescopiques 1, 2 sont rétractés, un volume partiel du gaz 14, jusqu'au point d'étanchéité, est empêché d'arriver au canal de transfert 18. L'invention est plus particulièrement applicable en combinaison avec des mécanismes de levage et de rabattement.
