圧器の制御バルブ。(1) Supply air that acts in opposite directions to both ends of the compression piston, which has a difference in effective area in the pressure-receiving part, and acts on a small pressure-receiving part with a small effective area by the pressure difference based on the difference in effective pressure-receiving area at both ends. In the booster, the above pressure booster repeats and continues a compression stroke in which the air is compressed to raise the pressure to secondary pressure, and a return stroke in which the piston is returned to its original position by releasing the primary pressure acting on a large pressure receiving part with a large effective area. It is equipped with a timing valve that is operated by the compression piston near the top and bottom dead center of the compression piston, and a switching valve that switches between supply and exhaust of air acting on the large pressure receiving part of the compression piston, and the switching valve is A control valve for a booster, characterized in that operating air is controlled by a timing valve.
