| description | PROBLEM TO BE SOLVED: To provide a differential pressure regulating valve with variable load function for a rolling stock that has simple structure and can be changed from a conventional differential pressure regulating valve without variable load function. SOLUTION: The differential pressure regulating valve for the rolling stock is equipped with a pair of valves (15, 17 and 16, 18) performing communication/ cutting off between two air springs 101, 102 arranged between a vehicle body and a bogie. When inner pressure difference between both air springs 101 and 102 becomes not less than a prescribed value, the pressure between both air springs 101 and 102 is made uniform by opening the valve in which valve elements 15, 16 are pressurized in a valve opening direction from a high-pressure side. Pistons 27, 28 installed in cylinder parts 23, 24 with the atmospheric chambers 29, 30 released to the atmosphere press the correspondingly arranged valve elements by the inner pressure received from one of the air spring sides into the valve opening direction through resilient members 19, 20.
