Beschreibung
Zusammenfassung:	A fluid control valve is made compact by changing the shape of a communication passage within the fluid control valve. The fluid control valve includes a valve casing, an electric valve disposed in the valve casing, and a relief valve disposed in the valve casing. The valve casing includes: a main passage that has a first valve port sealed by the electric valve; a bypass passage for bypassing the first valve port; a first valve chamber in fluid communication with the downstream side of the first valve port and housing the electric valve; and a second valve chamber in fluid communication with the upstream side of the first valve port and housing the relief valve. The bypass passage includes a communication passage configured to allow the first valve chamber and the second valve chamber to fluidly communicate with each other. The communication passage opens to a first side surface of the first valve chamber and/or into a side surface of the second valve chamber.
