ABSTRACT:
The machine is an engine or pump with a box shaped piston positioned between two stationary sidewalls. Opposite inward ends and inwardly facing moving sidewalls of the piston act with the two stationary case sidewalls and a block-shaped central head to define a pair of working chambers. The piston moves as restrained by a crankshaft to extract or add energy to the working chambers. Force is transferred between the piston and the crankshaft by means of a slide block on the crankshaft and the inner surface of a pair of parallel walls connected to the box shaped piston. Through the use of suitable cams and valves, four-cycle, two-cylinder equivalent engines and two-cycle, one-cylinder equivalent engines can be produced per piston. The planar walls of the machine maximize displacement while reducing mechanical stress and allowing use of heat resistant coating material, such as ceramics for thermal protection so that radiantly cooling rather than separate fluid or gaseous cooling systems can be used.
