Abstract
A vehicle body tilting device for railway vehicle is arranged to control the tilt of a vehicle body by exchanging compressed air between a pair of left and right air springs. This device includes: a control valve for tilt operation, connected between the air springs; a pump for tilt operation, connected between the air springs through the control valve; and a control device for controlling both the control valve and the pump. The control valve forms a circulation flow path for allowing compressed air, delivered by the pump, to circulate therethrough. Before controlling the tilt of the vehicle body, the control device drives in advance the pump to circulate the compressed air through the circulation flow path to provide a delivery standby state, changes over at predetermined timing the position of the control valve, and delivers the compressed air from one of the air springs to the other.
