Abstract

Amortisseur hydraulique télescopique de suspension de véhicule automobile, comportant un piston (10) fixé à une extrémité d'une tige (8) coulissant suivant une direction axiale dans un corps (2) afin de séparer deux chambres (14, 16) disposées de chaque côté de ce piston (10), la tige (8) comportant une liaison avec le piston (10) pivotante autour de l'axe de cette tige (8), qui transmet le mouvement axial au piston (10), et cette liaison pivotante comportant un passage de fluide reliant les deux chambres (14, 16), présentant une section de passage variable en fonction du pivotement du piston (10) autour de la tige (8).
