Abstract

La présente invention concerne un ensemble amortisseur dans lequel un élément déformable comprenant une structure de soufflet recouvre une ouverture d'un cylindre. L'ensemble amortisseur comprend : un cylindre (100) comprenant un espace dans lequel un fluide est rempli, le cylindre (100) comprenant une extrémité ouverte; un piston coulissant (110) disposé à l'intérieur du cylindre (100); un élément déformable (120) disposé au niveau de l'extrémité ouverte du cylindre (100) de manière à recouvrir l'extrémité ouverte du cylindre (100), le volume interne de l'élément déformable (120) étant variable; un trou d'écoulement (130) traversant le piston (110) de manière à guider le fluide de sorte que le fluide s'écoule à travers le piston (110); une partie d'ouverture/de fermeture (140) permettant d'ouvrir ou de fermer sélectivement le trou d'écoulement (130); et un élément d'ouverture/de fermeture (150) disposé au niveau d'un côté du piston (110) de manière à forcer la partie d'ouverture/de fermeture (140) à recouvrir le trou d'écoulement (130). l l Selon la présente invention, un amortisseur compact peut être fourni pour améliorer le rendement du travail.
