Title (EN) CYLINDER DEVICE AND VIBRATION DAMPING DEVICE FOR RAILWAY VEHICLE
(FR) DISPOSITIF À CYLINDRE ET DISPOSITIF D'AMORTISSEMENT DE VIBRATIONS POUR VÉHICULE FERROVIAIRE
(JA) シリンダ装置および鉄道車両用制振装置
Abstract:
(EN) A cylinder device (C1) according to the present invention comprises: a cylinder (2); a rod (4) inserted into the cylinder (2); a piston (3) that is slidably inserted into the cylinder (2), is connected to the rod (4) and partitions the inside of the cylinder (2) into a rod-side chamber (5) and a piston-side chamber (6); a tank (8); a discharge passage (21) that causes the rod-side chamber (5) to communicate with the tank (8); a relief valve (22) provided in the discharge passage (21); and an attenuation unit (23) that causes a larger pressure loss than the relief valve (22) when the speed of the piston (3) relative to the cylinder (2) becomes equal to or higher than a predetermined speed.
(FR) Un dispositif à cylindre (C1) selon la présente invention comprend : un cylindre (2) ; une tige (4) insérée dans le cylindre (2) ; un piston (3) qui est inséré coulissant dans le cylindre (2), est relié à la tige (4) et sépare l'intérieur du cylindre (2) en une chambre côté tige (5) et une chambre côté piston (6) ; un réservoir (8) ; un passage d'évacuation (21) qui amène la chambre côté tige (5) à communiquer avec le réservoir (8) ; une soupape d'évacuation (22) disposée dans le passage d'évacuation (21) ; et une unité d'atténuation (23) qui provoque une perte de pression plus grande que la soupape d'évacuation (22) lorsque la vitesse du piston (3) par rapport au cylindre (2) devient supérieure ou égale à une vitesse prédéterminée.
(JA) 本発明のシリンダ装置(C1)は、シリンダ(2)と、シリンダ(2)内に挿入されるロッド(4)と、シリンダ(2)内に摺動自在に挿入されるとともにロッド(4)に連結されて、シリンダ(2)内をロッド側室(5)とピストン側室(6)とに区画するピストン(3)と、タンク(8)と、ロッド側室(5)とタンク(8)とを連通する排出通路(21)と、排出通路(21)に設けられるリリーフ弁(22)と、シリンダ(2)に対するピストン(3)の相対速度が所定速度以上となるとリリーフ弁(22)より大きな圧力損失を生じさせる減衰部(23)とを備えている。
