Abstract
A high-pressure fluid discharge device that can adapt to large flow rates while being small in size has a diaphragm valve body that cooperates with a valve seat provided to a body to switch between communication and blocking between a first flow path and a second flow path. A pilot chamber and a valve chamber joined to the first flow path are sectioned by the diaphragm valve body, and the diaphragm valve body is provided with a pilot passage allowing communication between the valve chamber and the pilot chamber. The diaphragm valve body is also provided with a pilot-type spool valve that switches between communication and blocking between the pilot chamber and an excretion port.
