DRIVE DEVICE USING CHARGED AIR PRESSURE

摘要

In a drive device, two cylinders filled with air pressure are interconnected, and the pistons of the cylinders are pressed under the same pressure by compressed air supplied to the cylinders. The drive device has an external input device for applying an external input to the cylinders so that the pistons reciprocate alternately. The external input device causes the pistons to reciprocate alternately, and the reciprocation motion provides rotational force. The interconnected cylinders are multi-stage cylinders, pressurized air flow paths (22A, 22B) connected to each cylinder stage are formed in the multi-stage cylinders, and valves (17A, 17B) for opening and closing the flow paths are also provided in the cylinders.
