Abstract
A high-pressure fluid discharge device has an input port through which a high-pressure fluid is fed, a tank chamber which stores the high-pressure fluid, and a discharge port through which the high-pressure fluid is discharged. A diaphragm valve divides a pilot chamber and a valve chamber communicating with the tank chamber; the pilot chamber communicates with the valve chamber through a pilot passage; the valve chamber communicates with the discharge port through a discharge passage while the diaphragm valve is open; an opening-closing control valve is provided in open flow paths for opening the pilot chamber to the discharge passage; and the opening-closing control valve is opened and closed by the pressure of the fluid fed from the tank chamber.
