The gas is discharged through the first connection port 16, the hole 43a, the exhaust arc-shaped opening 33a, the exhaust flow path 28, and the exhaust port 15. If the piston 56 is at the starting end 58, it will not move, but if it is at another position, it will move towards the starting end 58 and the driven valve device 26 will rotate clockwise as shown. ..

In such a case, the driven member 22 always rotates by an angle substantially the same as the rotation angle of the main valve device 40. Therefore,
It is extremely easy to stop the piston 56 at an arbitrary position. Further, the operating speed of the piston 56 can be adjusted to a desired speed by appropriately adjusting the rotation speed of the driving valve device 40.

A control device for a pneumatic operating device, which comprises:
