Abstract

L'invention a pour objet un système d'amortissement hydraulique comportant un piston (10) ajusté dans un alésage (8), qui coulisse dedans suivant un axe principal (A) en présentant une longueur axiale de recouvrement (L) comprenant des surfaces de contact l'une sur l'autre, ce piston (10) séparant deux chambres hydrauliques (6, 12) disposées de part et d'autre, ce système d'amortissement étant remarquable en ce que la longueur de recouvrement (L) varie en fonction du déplacement du piston (10), et en ce que la surface de contact du piston (10) ou de l'alésage (8) comporte une rainure de passage du fluide (14) d'une chambre à l'autre (6, 12).
