PURPOSE:To speedily restore a proper pressure in a brake pipe by installing an automatic control mechanism by which a proper amount of high-pressure air is directly introduced into the brake pipe according to the decompression state on the brake pipe side, when a brake valve is set at operation position. CONSTITUTION:When a brake valve 4 is set to a control position, the decompression state in a brake pipe 5 is detected by a sensor 13, and the detection signal is sent into a microcomputer 13. The microcomputer 13 sets the high pressure air introducing pattern on the basis of the detection signals. When the brake valve 4 is set at operation position, the microcomputer 13 is linked and immediately opens a solenoid valve 11. Therefore, the high-pressure air in a high-pressure side air tank 2 is directly introduced into the brake pipe 5. After the lapse of the time set according to the high-pressure air introducing pattern set as described in the above, the solenoid valve 11 is closed, and the pressure in the brake pipe 5 is speedily set at a proper pressure. |
