Radial Air Engine
Radial Pneumatic Engine that runs on pressure, vacuum or both. In this simplified design each piston is a logic gate or valve (depending on you point of view) controlling the other piston it is coupled with. Powered with a unique continuous flow bellow system. Made with Scroll Saw Band Saw and Drill press.
My Air Engines all use my Piston-Valve design.
