置。One-way air is supplied to both ends of a compression piston whose pressure-receiving parts have different effective areas, and by using the pressure difference based on the difference in effective area, one-way air is applied to the small pressure-receiving part by the primary pressure acting on the large pressure-receiving part. is compressed and raised to secondary pressure, and this is
The compression stroke, which is stored in the next pressure storage chamber, and the return stroke, which returns to the original position by exhausting the first air supplied to the large pressure receiving section, are repeated and continued, and the operation is performed by sending and discharging the first air. In the booster, which controls switching between the compression stroke and the return stroke using a switching valve, the first valve stem, which can be adjusted from the outside, and the second valve stem, which moves according to the magnitude of the secondary pressure in the storage chamber, work together. 2 by opening and closing the exhaust passage of the switching valve or the exhaust passage of the compression piston, and arbitrarily adjusting the position at which both the valve stems cooperate to open and close the exhaust passage.
A secondary pressure setting device for a booster, characterized by setting a secondary pressure.
