Abstract

L'invention porte sur un cylindre à pression hydraulique comprenant un mécanisme amortisseur qui réduit la vitesse de la tige de piston lorsque la tige de piston est proche de la fin de sa course par rapport au tube du cylindre. Le mécanisme amortisseur comprend : un palier d'amortisseur monté sur la tige de piston ; une surface de cylindre amortisseur dans laquelle le palier amortisseur entre lorsque la tige de piston est proche de la fin de sa course ; une fente d'amortisseur définie entre la surface de cylindre amortisseur et le palier amortisseur et qui étrangle l'écoulement du fluide hydraulique ; un trajet de dérivation qui conduit le fluide hydraulique qui contourne la fente d'amortisseur ; et une résistance intercalée dans le trajet de dérivation. Un orifice est formé dans la résistance, et l'orifice étrangle l'écoulement du fluide hydraulique qui passe dans le passage de dérivation.
