流体制御装置。 In the fluid control device described above, the spool valve and the actuator are connected through a pair of main passages, and an operated check valve is provided in one of the main passages, and the operated check valve is opened by the pressure action of the other main passage. The spool valve has a communication passage that communicates one main passage with the other main passage, and this communication passage includes a back pressure valve that maintains a constant pressure in the communication passage, and a back pressure valve that maintains a constant pressure in the communication passage. A fluid control device comprising a check valve that allows flow only from one main passage to the other main passage.
