Abstract

PURPOSE:To make a brake unloosable for a desired car alone, by controlling only a pressure liquid being fed to the brake of the desired car in time of braking the whole train of cars. CONSTITUTION:A solenoid valve 11 is connected to the space between a control air receiver 5 and a brake pipe 2, while the solenoid valve 11 is controlled by a control circuit 12. That is to say, when pressure in the brake pile 2 is reduced to some extent and a braking command is issued to a control valve 4, the control circuit 12 is set in motion and the solenoid valve 11 is opened upon excitation whereby the brake pipe 2 and the control air receiver 5 are interconnected with each other. With this constitution, the pressure in the brake pile 2 comes equal to that of the control air receiver 5, causing the control valve 4 to be situated in a nonoperating position by force. Therefore, pressure air in a brake cylinder 8 is discharged to the open air so that a brake 1 is unloosed.
