Abstract

L'invention concerne un amortisseur télescopique hydraulique rétractable. Cet amortisseur comporte essentiellement un deuxième piston 10 coulissant de manière étanche le long de la tige de piston 4 et de la paroi de cylindre. En position de repos de ce piston et de fonctionnement normal de l'amortisseur, une liaison 25, 22, 23, est établie avec le réservoir 9 pour évacuer un trop-plein de liquide et l'air du cylindre. Lors du blocage, un milieu sous pression élevée est envoyé par le conduite 17 vers le second piston 10 par la liaison 13, 15 et vient en même temps fermer, par la plongeur 19 agissant sur la bille 20, le passage 25, 23. L'invention s'applique aux véhicules spéciaux nécessitant une position stable et fixe.
