Title:
DRIVE DEVICE USING CHARGED AIR PRESSURE
Document Type and Number:
WIPO Patent Application WO/2008/026758
Kind Code:
A1
Abstract:
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.
