Abstract
(EN)
A fluid damper which is capable of operating while automatically changing the damping force according to the movement of a piston without installing a sensor detecting the displacement of the piston and a controller controlling the supply of electric power. The fluid damper, in which the damping force is automatically changed according to the movement of the piston, comprises a fluid (8) having magnetism, a piston (2) of magnetic material, a cylinder (3) sealing the fluid (8) with magnetism and storing the piston (2), a piston rod (4) passed through the cylinder (3) and supporting the piston (2), magnetic field generating device (6) installed on the outside of the cylinder (3), first yoke member (5) disposed around the cylinder (3), and second yoke member (7) disposed around the piston rod (4) and on the outside of the cylinder (3). Thereby, a magnetic circuit can be partially formed.

L'invention concerne un amortisseur à fluide qui est capable de fonctionner tout en modifiant automatiquement la force d'amortissement en fonction du mouvement d'un piston sans qu'il ait besoin d'installer un capteur pour détecter le déplacement du piston et une unité de commande pour commander l'alimentation en énergie électrique. L'amortisseur à fluide, dans lequel la force d'amortissement se modifie automatiquement en fonction du mouvement du piston, comprend un fluide (8) ayant des propriétés magnétiques, un piston (2) fait d'une matière magnétique, un cylindre (3) enfermant hermétiquement le fluide (8) ayant des propriétés magnétiques et contenant le piston (2), une tige (4) de piston enfilée dans le cylindre (3) et soutenant le piston (2), un dispositif (6) de création d'un champ magnétique installé à l'extérieur du cylindre (3), un premier élément de culasse (5) disposé autour du cylindre (3) et un second élément de culasse (7) disposé autour de la tige (4) de piston et à l'extérieur du cylindre (3). De ce fait on peut former en partie un circuit magnétique.
