PROBLEM TO BE SOLVED: To achieve both a system for keeping the height of a vehicle body constant and a system for making the height of the vehicle body arbitrarily changeable, by a simple structure, in a height adjustment device for a railway vehicle.SOLUTION: A height adjustment device 100 for a railway vehicle, which adjusts the height of a vehicle body 1 with respect to a carriage 2, includes an operation body (operation piston 20) that is displaced depending on relative displacement of the vehicle body 1 with respect to the carriage 2, a valve body 30 that is axially moved by displacement of the operation body to switch between the supply and discharge of compressed air to and from an air spring 3, and an actuator 90 for axially driving the valve body 30.
【課題】鉄道車両の高さ調整装置において、車体の高さを一定の高さに保つシステムと、車体の高さを任意に変更可能なシステムと、の両方を簡便な構造で実現すること。【解決手段】台車2に対する車体1の高さを調整する鉄道車両の高さ調整装置100であって、台車2に対する車体1の相対変位に応じて変位する作動体(作動ピストン20)と、作動体の変位によって軸方向に移動して空気ばね3に対する圧縮空気の供給と排出を切換えるバルブ体30と、バルブ体30を軸方向に駆動するアクチュエータ90と、を備える。【選択図】図2
