摘要： PROBLEM TO BE SOLVED: To provide a control valve assembly for omitting a normal service part for a standard AB type cargo vehicle brake control valve, to utilize an emergency part only for controlling a backup pneumatic brake to an electropneumatic brake system. SOLUTION: In refilling a brake tube succeeding emergency brake actuation, a control chamber, for a restraining valve 42 into which brake cylinder pressure is supplied via high-pressure spool valve, is ventilated to the atmosphere, or brake cylinder pressure in a reverse damping passage 72 is separated from a brake tube, to ventilate a void 74 for a check valve to the atmosphere by using a plug 70 instead of a quick action emergency relaxing sheck valve. A means for discharging the brake cylinder pressure via the passage 72 can be realized, by displacing a reverse damp and spool valve to a relaxing position by an emergency piston during refilling the brake valve succeeding the emergency brake action.

摘要： PROBLEM TO BE SOLVED: To continuously keep the high speed for a long time by providing a solenoid valve control device to apply the excitation voltage lower than the rated voltage required to keep the driving condition after the excitation voltage over the rated voltage required to drive a solenoid valve device corresponding to a wheel to detect the sliding condition is applied for the prescribed period. SOLUTION: A speed and deceleration operating part 612 operates the speed and the deceleration of each shaft to detect the shaft of a wheel in a sliding condition based on the output from four speed operating parts 611 to receive the input of each speed signal of first, second, third and fourth shafts of a rolling stock, and the brake release command is outputted to the shaft. A solenoid valve control part 615 to receive the command applies the low holding voltage required for keeping the driving condition during the time zone while applying the periodically strong excitation force by the pulse-shaped voltage to corresponding releasing solenoid valve RV and holding solenoid valve HV. As a result, even a solenoid valve device of large capacity can be driven at high speed, and the excitation voltage is dropped after driving, and excitation can be continued for a long time.

摘要： 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.

摘要： PROBLEM TO BE SOLVED: To provide an air pressure controlling device capable of controlling an air pressure in a brake cylinder in response to a brake command pressure with high accuracy and conducting stable control by restraining fluctuation in the air pressure even when supplying and exhausting air to and from the brake cylinder at high speed. SOLUTION: This air pressure controlling device 11 is provided with a pressure sensor 13 for detecting air pressure in the brake cylinder as a controlled object, and a control part 15 for controlling a three-position electromagnetic valve 12 with the usage of an air pressure command value and the pressure detected by the pressure sensor 13. The control part 15 detects from the detected pressure by the pressure sensor 13 that the three-position electromagnetic valve 12 exists in a slow supply region at a slow supply position between a supply position and an overlap position or a slow exhaust region at a slow exhaust position between the supply position and the overlap position. When it is detected that the detected pressure rises or declines by a predetermined value, the three-position electromagnetic valve 12 is forcibly placed in the overlap position for a predetermined time from detection to keep the pressure in the brake cylinder statically.
