Abstract

A compressed fluid discharge control device is provided with a diaphragm valve. When an opening/closing operation member is operated, a pilot chamber opening/closing valve opens to open a pilot chamber. As a result, pressure within a valve chamber becomes higher than that in the pilot chamber and the diaphragm valve separates from a valve seat. Then, compressed fluid previously accumulated in a holding chamber flows into a discharge passage through the valve chamber and is discharged from the discharge opening of the discharge passage.
