Abstract

L'amortisseur comporte un corps cylindrique 100 contrenant un liquide et ayant une extrémité fixée à une partie non suspendue d'un véhicule, et une autre extrémité traversée par une tige d'amortissement 105 fixée à une partie suspendue du véhicule, la tige précitée étant solidaire d'un piston d'amortissement 106 monté à coulisse dans un tube interne 107 d'amortissement coaxial au corps cylindrique de l'amortisseur et de moindre diamètre que ce corps. L'amortisseur comporte en outre une chemise tubulaire 108 montée à coulisse autour du piston d'amortissement 106 et à l'intérieur du tube interne 107, la chemise coulissante 108 étant pourvue d'au moins une fenêtre longitudinale 109, la chemise coulissante, dans sa partie comprise entre le piston 106 et son extrémité opposée à la tige 105 du piston, presentant au moins un passage 110 en regard d'une ouverture 111 du tube interne 107. Application notamment aux amortisseurs du tybe séquentiel.
