    Abstract: A control valve in an intermittent air-generating device has a five-port valve, the inlet port of which is connected to a fluid supply source and the outlet port is connected to an air-spraying device. As a result of pilot air being supplied to a pilot input port, a valve element moves, and as a result of the inlet port and the outlet port being put in an ON state in which the two are in communication with each other, compressed air is sprayed from the air-spraying device. Meanwhile, as a result of the pilot air being discharged from the pilot input port by way of a discharge port, the valve element moves in the opposite direction and the inlet port and the outlet port are put in an OFF state in which the state of communication between the two is blocked. The ON state and OFF state alternate intermittently.

    Abstract: A compressed fluid discharge control device is provided with a diaphragm valve. When an opening/closing operation member is operated, a pilot chamber opening/closing valve opens to open a pilot chamber. As a result, pressure within a valve chamber becomes higher than that in the pilot chamber and the diaphragm valve separates from a valve seat. Then, compressed fluid previously accumulated in a holding chamber flows into a discharge passage through the valve chamber and is discharged from the discharge opening of the discharge passage.

    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.

    Abstract: A switching valve is constructed such that a rotor is rotatably provided inside a body and a cover member is provided with respect to the body so as to face a table part of the rotor. A gap having a prescribed interval is provided between an upper surface of the table part and the cover member, and a valve body biased toward the cover member side is provided to the table part. When rotating, the rotor does not slide on the bottom surface of the cover member, and leakage of a liquid from an inlet port is prevented due to the valve body seated on and closing an outlet port that is not the outlet port which is provided to the cover member so as to cause the liquid to be outputted therethrough.
