Abstract

L'invention concerne un pare-chocs à valve mobile entre des positions ouverte et fermée, permettant de modifier sélectivement le taux d'amortissement en compression du pare-chocs. La valve peut comprendre un système d'auto-centrage du corps de valve autour de l'arbre de valve. Le pare-chocs peut aussi comprendre un temporisateur, qui maintient la valve ouverte pendant une durée préétablie après l'ouverture initiale.
