Abstract
PURPOSE: To secure the liquid pressure at a touble in one system by stopping the pressure reducing control action in the other system while the liquid pressure is controlled and balanced in two systems of an X piping at each pressure reducing valve in a cylinder body.
CONSTITUTION: A liquid pressure is transmitted to right and left front wheel brakes 14 and 15 from two oil pressure chambers 13 of a master cylinder through 20, 21 and 22 while it is done to right and left rear wheel brakes 16 and 17 through pathes 20, 21, 23, 24, 25, 26 and 27. When the liquid pressure reaches a fixed level, a proportional decompression is performed by a sleeve piston 8 and a valve 6. When a trouble occurs in the system B, a piston 2 and a valve 6b move to the right to enlarge a clearance between a valve 6a and a piston 8a thereby stopping the proportional decompression in the system A. The same is done in case of a trouble in the system A. After the proportional decompression starts at the pathes 24 and 25 being cut, a difference in the oil pressure between pathes 26a and 26b move the piston 2 to the low pressure side together with the pistons 8a and b thereby equalizing the oil pressure.
