Title (EN) DAMPER
(FR) AMORTISSEUR
(JA) 緩衝器
Abstract:
(EN) This damper is provided with: a rod (2) inserted into a cylinder (1) so as to be capable of moving forward and backward in an axial direction; a piston (3) provided at the front end of the rod (2) and dividing the inside of the cylinder (1) into an extension-side chamber (R1) and a pressure-side chamber (R2); a rod guide (4) provided at the open end of the cylinder (1) and supporting the rod (2); a sub-cylinder (5) provided to the rod guide (4) and forming an annular gap (10) between the sub-cylinder (5) and the cylinder (1); and a sub-piston (6) which is provided on the outer periphery of the rod (2) at a position closer to the base end side than the piston (3), is in contact at the outer periphery thereof with the inner periphery of the cylinder (1), and can move into and out of the annular gap (10).
(FR) L’invention concerne un amortisseur équipé : d'une tige (2) insérée dans un cylindre (1) de façon à pouvoir se déplacer vers l'avant et vers l'arrière dans une direction axiale ; d'un piston (3) disposé à l'extrémité avant de la tige (2) et divisant l'intérieur du cylindre (1) en une chambre côté extension (R1) et une chambre côté pression (R2) ; d’un guide-tige (4) disposé au niveau de l'extrémité ouverte du cylindre (1) et portant la tige (2) ; d’un sous-cylindre (5) disposé sur le guide-tige (4) et formant un espace annulaire (10) entre le sous-cylindre (5) et le cylindre (1) ; et d’un sous-piston (6) qui est disposé sur la périphérie externe de la tige (2) de façon à être plus proche du côté d'extrémité de base que le piston (3), qui est en contact au niveau de sa périphérie externe avec la périphérie interne du cylindre (1), et qui peut entrer et sortir de l'espace annulaire (10).
(JA) 緩衝器が、シリンダ(1)内に軸方向に進退自在に挿入されるロッド(2)と、ロッド(2)の先端に設けられシリンダ(1)内を伸側室(R1)と圧側室(R2)に区画するピストン(3)と、シリンダ(1)の開口端に設けられロッド(2)を軸支するロッドガイド(4)と、ロッドガイド(4)に設けられシリンダ(1)との間に環状隙間(10)を形成するサブシリンダ(5)と、ロッド(2)のピストン(3)よりも基端側外周に設けられ、外周がシリンダ(1)の内周に摺接するとともに、環状隙間(10)に出入可能なサブピストン(6)とを備える。
