ブースタ装置。A booster piston 12 is fitted into a booster housing 10 having an inlet port 20 and a drain port 22 to form a piston chamber 13, a valve 15 is fitted into a shaft hole 14 of the booster piston 12, and a spring 17 is used to close the booster piston 12. The valve 15 is held in a non-operating position, and a fourth port 29 is bored in the valve 15 to disconnect the drain port 22 and the piston chamber 13. The first to cut through
・A third port) 24, 27 and a small diameter portion 30 are formed, and the positional relationship of each port is such that when the valve 15 is in the booster non-operating position, the inlet port 20 and the piston chamber 13 are shut off, and the train port 22 and the piston are closed. A hydraulic booster device characterized in that the inlet port 20 and the piston chamber 13 are communicated with each other, and the drain port 22 and the piston chamber 13 are communicated with each other when the booster is in the booster operating position.
