Abstract

L’invention concerne un amortisseur hydraulique de suspension pour véhicule, notamment automobile, comprenant un vérin hydraulique (1) comportant un piston (3) mobile en déplacement dans un cylindre (2), une chambre (5) dont le volume est variable en fonction de la position du piston (3) dans le cylindre (2) et comprenant un fluide incompressible (7), et une tige d’amortisseur (4). L’amortisseur comporte un manchon compressible (6), élastiquement déformable entre un état déployé et un état compressé, disposé dans ladite chambre (5) de cylindre entre une paroi (20) de cylindre et une paroi (30) du piston, ledit manchon (6) définissant dans ladite chambre (5) un espace externe (51) et un espace interne (50). Le manchon (6) comporte au moins une ouverture traversante pour livrer passage audit fluide incompressible (7) entre ledit espace externe (51) et ledit espace interne (50) quand le manchon (6) passe de son état déployé à son état compressé.
