Abstract

L'invention concerne un amortisseur hydraulique. Selon l'invention, il comprend un cylindre 1 contenant de l'huile, un piston 6 coulissant dans le cylindre, une tige creuse 8 s'étendant d'un côté du piston et faisant saillie hors du cylindre, un organe tubulaire 11 monté de l'autre côté du piston, et dont l'intérieur communique avec l'intérieur de la tige creuse, un passage de connexion 9, 8, 10, 13 comprenant l'intérieur de la tige creuse et l'intérieur de l'organe tubulaire et mettant en communication les côtés opposés du piston, un organe de tige 14 s'étendant rotatif à travers l'intérieur de la tige creuse et faisant saillie hors du cylindre, un corps de vanne 16 reçu coulissant dans l'organe tubulaire et connecté à l'extrémité interne de l'organe de tige pour changer l'aire effective du passage de connexion, et une butée restreignant le mouvement de rotation de l'organe de tige à un angle inférieur à 360 degrés . L'invention permet notamment l'ajustement de la force de résistance de l'amortisseur.The invention relates to a hydraulic shock absorber. According to the invention, it comprises a cylinder 1 containing oil, a piston 6 sliding in the cylinder, a hollow rod 8 extending from one side of the piston and projecting out of the cylinder, a tubular member 11 mounted from the other side of the piston, and the interior of which communicates with the interior of the hollow rod, a connection passage 9, 8, 10, 13 comprising the interior of the hollow rod and the interior of the tubular member and communicating opposite sides of the piston, a rod member 14 rotatably extending through the interior of the hollow rod and projecting out of the cylinder, a valve body 16 slidably received in the tubular member and connected to the inner end of the rod member to change the effective area of the connecting passage, and a stopper restricting the rotational movement of the rod member to an angle less than 360 degrees. The invention allows in particular the adjustment of the resistance force of the shock absorber.
