Abstract

Amortisseur dans lequel des plateaux mobiles (6) auxquels une force externe est transmise et des plateaux fixes (7) qui ne sont pas reliés fonctionnellement aux plateaux mobiles sont agencés en alternance dans un carter (1) contenant un fluide visqueux (A). Une tige filetée (8) régulant la pression d'un liquide, permettant d'augmenter et de diminuer la densité du fluide visqueux, est visée à travers la paroi du carter. Selon que la tige filetée est vissée en avant ou en arrière, la densité du fluide visqueux dans le carter augmente ou diminue, respectivement, de sorte que l'on peut augmenter ou diminuer au niveau requis la viscosité du fluide pour permettre le réglage désiré de la résistance au cisaillement visqueux et, partant, de la force de freinage de l'amortisseur.
