Abstract

NOUVEL AMORTISSEUR L’invention concerne un amortisseur à huile (A) comportant un piston (110) monté à l'extrémité d'une tige mobile (100) se déplaçant dans un corps cylindrique creux (200), la tige mobile (100) comportant au moins un orifice latéral (120) reliant le second volume de travail (V2) au premier volume de travail (V1) par au moins un passage central (130) réalisé dans la tige mobile (100). L’amortisseur est remarquable en ce qu’il comprend, logé dans la tête (210) de l’amortisseur, un moyen (400) de détection du franchissement d’un seuil de contrainte exercée sur l’amortisseur et de commande sans moyens électrique ou électronique de l’ouverture et de la fermeture d’une conduite de passage de l’huile reliant le passage central (130) réalisé dans la tige mobile (100) au premier volume de travail (V1) à des fins de détente rapide de l’amortisseur.
