よシブレーキ制御される。The brake cylinder control valve 2 is attached to the air brake pipe BP, and operates the brake cylinder BC to apply the brake when the pressure in the air brake pipe BP falls below a specified value. The vacuum brake control valve 3 is controlled by the air pressure of the air brake 'fBP, and controls the air pressure of the vacuum brake pipe VBP. The brake application valve 4 is attached to the air brake pipe BP, and 1! ! When the magnetic valve 5 is demagnetized, the air in the air brake pipe BP is discharged to the atmosphere. Air brake pipe B
P and vacuum brake pipe VBP are each connected to another vehicle by a boss 67. Then, the following vehicle is brake-controlled by the pressure of the air brake pipe BP or the vacuum brake -fVBP.

には空気ブレーキが働かないという状態が発生する。According to this brake system, if the air brake pipe BP of another vehicle is damaged or if the conductor's valve (not shown) or the like is operated, the pressure in the air brake pipe BP of the locomotive decreases, so the brake cylinder is controlled. Valve 2 operates and can move the brake cylinder BC, but if the vacuum brake pipe VBP of another vehicle is damaged or the conductor valve (not shown) is operated, the air brake pipe BP of the locomotive may be damaged. Since the pressure does not change, the brake cylinder control valve 2 does not operate, and therefore the brake cylinder Bc also does not operate, resulting in a situation in which the air brake does not work on the locomotive.

レーキシリンダが動きブレーキが働く。By connecting the solenoid valve of the brake application valve in series with the pressure switch installed on the vacuum brake pipe, it is possible to demagnetize the solenoid valve when the pressure of the vacuum brake pipe falls below the specified value. Due to this movement K of the solenoid valve, the brake application valve can discharge the air in the air brake pipe to the atmosphere. Then, the brake cylinder control valve operates, the brake cylinder moves, and the brake is applied.
