Abstract

L'invention porte sur un système de suspension (10) passif notamment pour un véhicule automobile comportant: - un vérin (11), - un circuit de fluide (18) mettant en communication fluidique une chambre de compression (15) et une chambre de détente (16) du vérin (11), - le circuit de fluide (18) comportant au moins un premier augmentateur inertiel (20.1) et un deuxième augmentateur inertiel (20.2), - ledit système de suspension (10) étant apte à fonctionner en attaque ou en détente suivant un sens de déplacement du piston (13) à l'intérieur du corps (12), - le circuit de fluide (18) comportant en outre un clapet anti-retour (23) monté en parallèle avec le deuxième augmentateur inertiel (20.2) de façon à pouvoir court-circuiter, en fonction d'une orientation choisie du clapet anti-retour (23), le deuxième augmentateur inertiel (20.2) dans un fonctionnement en attaque ou en détente du système de suspension (10).
