<p>PURPOSE:To provide a piston which has a good efficiency to compress two rounds by rotating one round in a single cylinder, a simple structure, and a light weight. CONSTITUTION:A double-side piston in which a compression surface of a piston 1 used normaly for general purpose is installed revesrely to one side and the other side is formed, an oval hole is opened at the center, a rotary shaft 3 and a cam 2 installed to the shaft 3 are rotated in the hole so as to move the piston laterally, and an air or a mixture gas in both cylinders are compressed alternatively, so as to form a system to operate the double-side piston.</p> |
