Title (EN) SEMIACTIVE DAMPER
(FR) AMORTISSEUR SEMI-ACTIF
(JA) セミアクティブダンパ
Abstract:
(EN) The semiactive damper (D) according to the present invention is provided with: a cylinder (1); a rod (2) inserted movably within the cylinder (1); a piston (3) which is slidably inserted in the cylinder (1) and divides the interior of the cylinder (1) into a rod side chamber (4) and a piston side chamber (5); a tank (6); an inlet passage (7) permitting only a flow of a working fluid from the tank (6) toward the piston side chamber (5); a damping passage (8) putting the rod side chamber (4) and the tank (6) in communication or putting the rod side chamber (4) and the piston side chamber (5) in communication; a variable damping valve (9) provided to the damping passage (8); and a detection unit (10) for detecting the expansion and contraction direction due to pressure in the piston side chamber (5).
(FR) L'invention concerne un amortisseur semi-actif (D) qui est pourvu : d'un cylindre (1) ; d'une tige (2) insérée mobile à l'intérieur du cylindre (1) ; d'un piston (3) inséré coulissant dans le cylindre (1) et qui divise l'intérieur du cylindre (1) en une chambre côté tige (4) et une chambre côté piston (5) ; d'un réservoir (6) ; d'un passage d'entrée (7) permettant uniquement un écoulement d'un fluide actif depuis le réservoir (6) vers la chambre côté piston (5) ; d'un passage d'amortissement (8) mettant la chambre côté tige (4) et le réservoir (6) en communication ou mettant la chambre côté tige (4) et la chambre latérale de piston (5) en communication ; d'une soupape d'amortissement variable (9) disposée sur le passage d'amortissement (8) ; d'une unité de détection (10) destinée à détecter la direction d'expansion et de contraction dues à la pression dans la chambre côté piston (5).
(JA) 本発明のセミアクティブダンパ(D)は、シリンダ(1)と、シリンダ(1)内に移動自在に挿入されるロッド(2)と、シリンダ(1)内に摺動自在に挿入されてシリンダ(1)内をロッド側室(4)とピストン側室(5)とに区画するピストン(3)と、タンク(6)と、タンク(6)からピストン側室(5)へ向かう作動流体の流れのみを許容する吸込通路(7)と、ロッド側室(4)とタンク(6)とを連通するか或いはロッド側室(4)とピストン側室(5)とを連通する減衰通路(8)と、減衰通路(8)に設けられた可変減衰弁(9)と、ピストン側室(5)内の圧力により伸縮方向を検知する検知部(10)を備える。
