Abstract

Cet appareil est du type de ceux dans lesquels le piston coulissé axialement dans un cylindre dont il divise l'intérieur en deux chambres remplies de fluide et qui présente à l'une de ses extrémités des moyens de guidage et d'étanchéité pour la tige de piston, la butée hydromécanique étant disposée dans l'espace de section annulaire défini entre le cylindre et la tige de piston et comportant une bague d'amortissement sollicitée par un ressort, tandis que la tige de piston est munie d'une bague de butée. Dans l'appareil selon l'invention, il est prévu une bague supplémentaire d'actionnement 14, qui coopere avec la bague d'amortissement 12 sollicitée par un ressort et sert d'appui à l'une des extrémités d'un ressort 15, dont l'autre extrémité s'appuie contre la bague de butée 16 dont est munie la tige de piston 6.
