Abstract

L'invention concerne un amortisseur hydraulique du type à deux cylindres coaxiaux. Cet amortisseur comprend un piston 22 et un corps de soupape 16 comportant chacun des passages axiaux étranglés 42 commandés par un obturateur à disques flexibles maintenu contre le piston ou le corps de soupape par un ressort 56 maintenu entre un capuchon fixe 58 et un capuchon glissant ayant une partie surélevée pour appuyer les disques contre leur siège tout en permettant leur flexion. L'invention s'applique aux amortisseurs de chocs hydrauliques du type télescopique.
