To provide a vibrationless structure under an operation condition in a compression engine.

The shape of the compression engine inside is changed from a conventional structure (the inside of the compression engine in an engine and an air compressor). The inside (capacity) of the compression engine is formed in a true sphere (a ball shaped inner surface) structure. A rotary disk type piston, a rotary compression internal moving cylinder wall, and a rotary cylinder type compression internal sealed shaft rotate in a compound manner to enable an internal compression action the same as a conventional means. Thus structure includes suction and exhaust cycles and can operate without vibration.
