PURPOSE: To achieve the electro-pneumatic braking operation in a similar manner to that of 26-E1 type brake valve by providing an electric switch to be operated by the pilot pressure from a brake valve device. CONSTITUTION: A brake valve means to be operated to generate one discrete pressure condition in a first passage when a brake valve device 36 is loosened, and to generate the other discrete pressure condition when the brake valve device 36 is held, is provided. In addition, first pressure switching means 63, 64 which are responded to the other pressure condition of the first passage and operates an electro-pneumatic means so that the discharge of the fluid under pressure from a brake cylinder device 52 is cut off. |
