Abstract

PURPOSE: To miniaturize and simplify a valve structure, by constituting a servo- piston such that a valve of an accumulator is closed and opened by means of a convex cum located on a member moving in an axial direction.
CONSTITUTION: A check valve 84 seats on an opening end of passage 27 as a result of a forward movement of an input shaft 13. Then, an arm part 61 of a No.1 member 58 is hooked in a shoulder portion 70 of the input shaft 13 which is then going to advance further in such a condition as brings a front end of a No.2 member 60 in contact with a rear end of a servo-piston 8. Thus the No.1 member 58 advances toward the No.2 member 60 and slides between cam surfaces 63 and 66 to be guided into a hole 57. The No.2 member 60 deforms a claw 68, moving in a radius direction against a spring 52. As a result of a valve element 51 parting from a present position thereupon, a high pressure fluid in an accumulated pressure chamber 44 is fed to a pressure chamber 10 through passages 45 and 47, serving as a servo-pressure to move forward the servo-piston 8.
