Abstract (en)
Provided is an ejection device that can achieve lowered ejection sound. An ejection device (2) includes a high-pressure circuit (29, 60, 160) and a low-pressure circuit (50, 70, 170) for supplying compressed air to air nozzles (22) through which the compressed air is ejected to a track switch unit (10), a first solenoid valve (24A), a second solenoid valve (24B), a third solenoid valve (53) and a fourth solenoid valve (54) provided in the high- or low-pressure circuit (29, 50, 60, 70, 160, 170) for controlling the pressure of the compressed air supplied to the air nozzles (22), and an ejection control device (20).
