Abstract
L'invention concerne un amortisseur hydraulique de suspension de véhicule automobile comprenant un piston (6) coulissant dans un corps cylindrique et comprenant deux dispositifs mobiles (11, 12) coulissant dans des logements (13, 14) respectifs sous l'effet de la pression, chaque dispositif mobile divisant un des logements entre un premier volume (18a, 18b) comprenant un fluide à inertie et un deuxième volume (19a, 19b), le piston comprenant un premier passage de fuite (9) et un deuxième passage de fuite (10) reliant une première chambre à une deuxième chambre du corps. Le piston comprend une came (3) en liaison mécanique avec les deux dispositifs mobiles actionnant le pivotement de la came autour d’un axe (20) pour fermer ou ouvrir les passages de fuite sous l’effet de la pression d’un fluide d'amortisseur. (Fig. 4)
