Abstract

Amortisseur hydraulique télescopique de suspension de véhicule automobile, comportant un piston (10) monté sur une tige (8) de l'amortisseur coulissant suivant une direction axiale dans un corps (2) de l'amortisseur de forme cylindrique de génératrice ladite direction axiale, le piston séparant deux chambres (14, 16) dans le corps, le piston (10) étant contraint angulairement par rapport au corps d'amortisseur (2) autour de la tige (8), et la tige (8) comportant une liaison avec le piston (10), qui couple leur mouvement relatif de translation suivant l'axe de la tige (8) avec leur mouvement relatif de rotation autour dudit axe.
