Abstract

PURPOSE:To absorb an allowance and stabilize the motion of each system by connecting pistons of fluid pressure control valves of two systems to a load detecting measure through a locking lever and restricting a slant angle of the locking lever in case of trouble of one system. CONSTITUTION:A body 1 is provided with valve P of two systems and a piston 5 of each system is connected to a load detecting member 11 through a lever 8, which is provided with a supporting point 9 in its center and supporting points 10 on its right and left to restrict a slant angle. Slanting of the lever 8 may bring about absorption of an allowance of each valve and conformity of braking property of two systems. Further, restriction on a slant angle of the lever 8 excludes mechanical enforcement from the control valve and results in its stabilized action.
