Abstract: A fluid control valve includes a supply-air passage allowing a first port and a second port to communicate with each other, an exhaust-air passage allowing the second port and a third port to communicate with each other, a first check valve provided to the supply-air passage, a second check valve provided to the exhaust-air passage, a valve element that opens and closes a passage from the second port to the third port, and a valve hole in which the valve element is housed. The exhaust-air passage is provided between the valve hole and the valve element. The valve element has a first pressure-receiving surface that causes a fluid pressure at the first port to act, and a second pressure-receiving surface that causes a fluid pressure at the second port to act.

Abstract: A flow control valve adjusts an opening degree of a second channel by moving a needle valve in a first axis direction in accordance with a rotating operation amount of a knob provided at the first body, and includes a scale body, and a scale reading part that indicates the scale mark corresponding to the rotating operation amount of the knob, and a clutch mechanism that changes the scale mark of the scale body when the knob is rotated. The clutch mechanism includes an engaging portion, an engaged portion, and a clutch drive mechanism, and the scale reading part and the scale body rotate integrally when the engaging portion and the engaged portion are engaged. The clutch drive mechanism releases engagement between the engaging portion and the engaged portion when the knob is rotated and, after the scale mark is changed, re-engages the engaging portion with the engaged portion.

Abstract: Inside a valve housing equipped with a first flow path and a second flow path that connect in parallel with a first port and a second port, there are provided a needle valve body that opens/closes a throttle hole in the first flow path, a check valve that opens/closes the second flow path, and a piston that performs an open/close control of the needle valve body through the interaction of the pressure of a fluid introduced into a pressure chamber and the spring force of a compression spring. The needle valve body is formed at the tip of a rod coupled to the piston. Inside the rod and the needle valve body there is formed a conduction hole connecting the throttle hole and the pressure chamber.
