Abstract

Amortisseur hydraulique comportant un corps cylindrique (2) disposé suivant un axe principal, un piston fixée (4) fixé à l'extrémité d'une tige axiale (6), coulissant dans le corps (2) en séparant une chambre de détente (10) du côté de la tige (6) d'une chambre de compression (8) du côté opposé à cette tige (6), ce piston (4) comprenant un passage principal avec restriction (12) d'une chambre à l'autre, un passage secondaire d'une chambre à l'autre (8, 10), comprenant un orifice réglable (16), et un système de masselottes pressé par des ressorts, qui se déplace par inertie dans une direction radiale sous l'effet d'accélérations radiales de l'amortisseur, en modifiant la section de l'orifice réglable (16).
