Abstract

Jambe élastique, de préférence pour trains d'atterrissage d'avions, constituée par un piston, une tige de piston et un vérin, la roue étant montée à l'extrémité libre de la tige de piston et la chambre de compression du vérin raccordée à une alimentation en fluide sous pression par l'intermédiaire d'une ou plusieurs valves. La chambre de compression 5 du vérin 1 est raccordée à un dispositif de réglage de la charge 7, 8, 9, 10, 11 qui règle l'admission ou l'évacuation fluide sous pression en tant que fonction de la caractéristique élastique recherchée.
