PROBLEM TO BE SOLVED: To provide a fluid control valve which can be constituted compact in size by using the small number of parts for automatically discharging the pressure fluid of an output chamber at a secondary side when a pressure fluid of an introduction chamber at a primary side is relieved.SOLUTION: A fluid control valve (2) comprises: a main body part (4) in which an introduction chamber (41) into which fluid is introduced from a pressure fluid source and an output chamber (42) which is connected to the introduction chamber (41) via a passage (40) are formed; a valve member (5) which can open and close the passage (40), and in which a communication part (50) for making the introduction chamber (41) and the output chamber (42) communicate with each other is formed; and an elastic member (6) which is arranged at the communication part (50), brings the communication part (50) into a closed state by its own elastic force, is deformed by a rise of the pressure of the output chamber (42) higher than that of the introduction chamber (41), and brings the communication part (50) into an open state from the closed state.SELECTED DRAWING: Figure 1 |
