Abstract

L'invention a trait à un amortisseur hydraulique (2) comprenant une enveloppe cylindrique (4) contentant un fluide ; un piston (6) monté coulissant dans l'enveloppe cylindrique et comprenant au moins un passage (12.1, 14.2) pour le fluide ; une tige (8) reliée au piston (6) et traversant l'enveloppe (4) ; et un système amortisseur(10, 14, 16, 18) de rotation générée par un enfoncement de la tige (8) dans l'enveloppe (4).The invention relates to a hydraulic shock absorber (2) comprising a cylindrical casing (4) containing a fluid; a piston (6) slidably mounted in the cylindrical casing and comprising at least one passage (12.1, 14.2) for the fluid; a rod (8) connected to the piston (6) and passing through the casing (4); and a damping system (10, 14, 16, 18) of rotation generated by a depression of the rod (8) in the casing (4).
