Abstract

PURPOSE: To provide an air driving apparatus, wherein a power cylinder and a pilot cylinder are communicated with each other, and the power cylinder and the pilot cylinder are coacted to open or close an air valve, so that the power piston is caused to reciprocate and therefore power is effectively obtained.
CONSTITUTION: When compressed air is fed to a feeding port 8, a switch piston 2a is pushed and therefore an air valve 18 is forced against a disc 12. Consequently the compressed air is introduced through a groove 17, a chamber 13 and ports 19, 21 into a cylinder 1 to retract a power piston 2 against the force of a spring 4. At the same time, the compressed air flows through a groove 25 into a pilot cylinder 29, and when an forward end of a pilot piston 23 has passed a signal air inlet 34, a signal piston 2b can be pushed up from its back. When the air valve 18 is spaced from the disc 12, the feeding of the compressed air will be prevented, the air within the cylinder 1 will be discharged from a discharge port 22, and the piston will be moved forward by the action of the spring 4.
