The relay valve to the brake cylinder, in addition..., the emergency brake system has an automatic 5-week automatic valve that adapts to the load, and expands the valley corresponding to the total weight of the vehicle auxiliary including the H-space P-reset This output is supplied to the above-mentioned Jiangzhong, k-valve (for example, refer to Japanese Patent Publication No. 2000-2777). In the above-described conventional brake control wear, ^ ^ ^, the use of the relay valve and the emergency load-adjusting automatic adjustment valve as the different structural parts are divided into four (4) configurations, so the piping connection between them becomes In addition, since there are solenoid valves and control panels, etc., the number of parts for disasters is also large. Therefore, there is naturally a difficulty in that a large installation space is required. Further, as shown in FIG. 2 of Patent Document 1, in the case of the waterproof cover, when the control panel is disposed in the open space on the upper side of the magnetostatic valve, the upper control panel is easily received by the solenoid valve. The effect of heat dissipation is such an adverse situation.
