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)The invention relates to a motor vehicle suspension hydraulic shock absorber comprising a piston (6) sliding in a cylindrical body and comprising two mobile devices (11, 12) sliding in respective housings (13, 14) under the effect of pressure , each mobile device dividing one of the housings between a first volume (18a, 18b) comprising an inertial fluid and a second volume (19a, 19b), the piston comprising a first leakage passage (9) and a second leakage passage ( 10) connecting a first chamber to a second chamber of the body. The piston comprises a cam (3) in mechanical connection with the two movable devices actuating the pivoting of the cam around an axis (20) to close or open the leakage passages under the effect of the pressure of a fluid. 'shock absorber. (Fig.4)
