Abstract

L'invention concerne un ressort (1) de gaz pourvu d'un couvercle basculant (4) conçu pour absorber des charges non axiales, ce qui évite donc que les efforts provoqués par ces charges causent des avaries et diminuent la durée de vie utile du ressort (1). Le couvercle (4) est divisé en une partie extérieure fixe (4a) solidaire du corps (2) et une partie intérieure basculante (4b) présentant un orifice sur lequel se déplace la tige (3), les deux parties (4a, 4b) étant unies au moyen d'une surface de contact au moins partiellement sphérique, de sorte que la partie intérieure basculante (4b) est orientable. En outre, le ressort (1) comprend un joint torique (5) supplémentaire disposé entre la partie extérieure fixe (4a) et la partie intérieure basculante (4b) du couvercle (4) pour éviter les fuites de gaz. L'extrémité de la tige (3) comprend aussi un élément mobile (7) qui a une capacité de déplacement radial pour absorber les mouvements horizontaux.
