Abstract

Amortisseur hydraulique de suspension de véhicule automobile, comportant un piston d’amortissement (4) fixé à une tige (2), coulissant suivant un axe principal (A) en délimitant une chambre de compression (6) se vidant lors d’une compression de la suspension, et une chambre de détente (8), et comportant une colonne de fluide à inertie (10) reliant les deux chambres (6, 8) entre elles, le piston d’amortissement (4) comportant un circuit de dérivation reliant les chambres de compression (6) et de détente (8), passant par un volume de dérivation (20) comprenant un piston de contrôle (28) présentant des perçages calibrés (32), séparant une chambre d’ouverture (34) recevant la pression de la chambre de détente (P1), d’une chambre de fermeture (36) contenant un ressort d’équilibrage (30) qui pousse ce piston de contrôle (28) à l’encontre de la pression de la chambre de détente (P1), vers une position qui tend à fermer le circuit de dérivation.
