Abstract

Cet amortisseur hydraulique est perfectionné de façon à présenter une caractéristique d'amortissement qui décroit brusquement lorsque le piston atteint par rapport au cylindre une vitesse de déplacement déterminée. A cet effet, il comporte, en parallèle avec un premier passage calibré 12 un trajet supplementaire 21, 22, 23, 20 qui est commandé par un obturateur 17 soumis aux actions antagonistes d'un ressort de rappel 18 et d'une pression représentative de la vitesse de déplacement du piston 1.
