Rotary heat engine

An enclosed chamber internal combustion engine comprises:

• Two opposing rotary discs having at least one half-cylindrical chamber located around its perimeter;
• At least one piston located in each said half cylindrical chamber.
• Approximately half of each said piston is attach permanently to one said rotary disc and the other half of said piston is formed to fit inside the opposing said rotary disc.
• The section of the said piston which is not permenately fixed to the said rotary disc slides in the said half cylindrical chamber of the opposing said rotary disc.
• Sealing means provided in areas of said rotary disc for preventing said piston and said half-cylindrical chamber from fluid leakage.
• Each said rotary disc is formed with a mechanism, which allows said rotary disc to rotate in only one direction.
• Centered in said rotary disc is a passage, which allows an output shaft to rotate.
• An exterior casing formed to fit the exterior of said rotary discs:
• Said exterior casting is formed with a concentric passage, which allows said output shaft to rotate.
• Said exterior casting is formed with at least one intake port and at least one exhaust port.
• If necessary said exterior casing is formed with at least one spark plug.
• Said output shaft and said rotary disc is formed with mechanisms which allow said rotary disc to engage
• Said output shaft in only one direction.
