Abstract
PURPOSE: To relax and absorb the shock generated when input load increases by arranging a buffer means between the large diameter cylinder piston and the small diameter cylinder piston in a stepped master cylinder.
CONSTITUTION: The large diameter cylinder 12 and the small diameter cylinder 13 are formed inside the cylinder body 11 of the stepped master cylinder 10 toward the longitudinal direction. The large diameter piston 14 is fit in the large diameter cylinder so as to be able to slide. The left piston is formed for the oil replenishing chamber 11 and the right one for the low temperature chamber 15. Both chambers communicate through the communicating hole 18 and the primary cup 17. The small diameter piston 26 is fit in the small diameter cylinder and its right and left chambers communicate through the communicating hole 31 and the primary cup 32. The elastic body 36 is inserted between the pistons 14 and 26. This relaxes the shock of the force which is transmitted from the large piston to the small piston.
