摘要： PURPOSE: To improve the travel stability of a car body in preventing a cylinder on one side from extending at the same time by opening a bypass circuit via a pilot check valve at the other side by means of high pressure in this main circuit whenever a cylinder on the other is extending. CONSTITUTION: With the body 1 of a train traveling on a curved line, for example, at the time of extending a cylinder 7a on one side, a servo solenoid valve 11a on one side is selected, and operating oil from a pump 10 is fed to the one side cylinder 7a via a main circuit 12a. Then a cylinder 7b on the other is contracted by another servo solenoid valve 11b, keeping another main circuit 12b in low pressure. Therefore a pilot check valve 15a on one side is kept closed intact as its pilot pressure is not raised, so the one side cylinder 7a extends, tilting the car body 1. At this time, a pilot check valve 15b on the other is opened by dint of high pressure in the one side main circuit 12a, through which the operating oil is set free to a tank 10 from a bypass circuit 14b.
