Abstract

PURPOSE: To elliminate the unbalance of two liquid pressure chamber and to improve the safety, by means of setting larger the mounting load of the first spring than the second spring.
CONSTITUTION: Pistons 15,16 are slidably inserted into a cylinder hole with step 12. An expanding diameter head part 31 of a rod 30 which is screwed with the second piston 16 inserts in a concaved place 33 of the first piston 15, and a pin 34 of the first piston 15 is allowed to be penetrated in a long hole 32 of the expanding diameter head part 31. The first spring 38 is arranged between left end part of a retainer 37 free inserting on the outer circumference of the rod 30 and the second piston 16, and the second spring 40 is arranged between the second piston 16 and the closed end of the cylinder hole 12. The liquid pressure of the same pressure is allowed to be supplied to a brake system by means of allowing the pressure of liquid pressure chambers 18,19 to be raised at the same time.
