Abstract

Absorbeur hydraulique de chocs. Cet absorbeur se caractérise par le fait qu'il comprend un cylindre intérieur et un cylindre extérieur coulissant l'un dans l'autre, un premier desdits cylindres comportant une tige de piston orientée longitudinalement dans ce cylindre et munie d'un piston, un second cylindre comportant une première paroi, ou cloison, orientée radialement, percée d'un trou par lequel passe ladite tige de piston et divisant l'espace clos délimité par lesdits cylindres intérieur et extérieur, ledit second cylindre comportant en outre une seconde cloison orientée radialement, située entre ladite première cloison et ledit piston et traversée par ladite tige de piston, et une pièce élastique en forme d'anneau, appliquée fermement et de façon coulissante sur ladite tige de piston entre ladite première cloison et ladite seconde cloison. Application à la réalisation de véhicules automobiles.
