High-pressure fluid discharge device

A pressurized fluid discharge device comprising an inlet port to which a pressurized fluid is supplied, a tank chamber configured to store the pressurized fluid, and a discharge port configured to discharge the pressurized fluid, wherein:

• the pressurized fluid discharge device further comprises a diaphragm valve configured to separate a pilot chamber and a valve chamber communicating with the tank chamber;
• the pilot chamber communicates with the valve chamber through a pilot passage provided inside the diaphragm valve;
• when the diaphragm valve opens, the valve chamber communicates with the discharge port through a discharge passage;
• the pressurized fluid discharge device further comprises an opening and closing control valve provided in a release flow path and configured to open the pilot chamber to the discharge passage in a state where the diaphragm valve is closed;
• and
• the opening and closing control valve is operated to open and close by a pressure of fluid that is supplied from the tank chamber through an operating air flow path without passing through the valve chamber.
