Abstract: FIG. 2 suggests an engine idea in which two interlocked rotors stop and turn in alternate fashion. If this suggestion is restructured as follows it would lead into the useful embodiments of this patent and more: The blades of a Front rotor are interlocked with the blades of a Back rotor. With the help of a Front motor and a Back motor, a computer is able to drive said Front rotor and said Back rotor. The computer controls the sealed chambers between the blades of the Front rotor and the blades of the Back rotor to bring about the strokes similar to the strokes of the conventional internal combustion engines. Said structure therefore yields to the formation of three embodiments: a Rotary Internal Combustion Engine (RICE), a Rotary Internal Combustion Generator, and a Rotary Compressor/Liquid Pump (RC/LP).

Abstract: In a conventional internal combustion engine the cylinder wall constrains the connecting rod to a straight up and down motion. The wall of a valve-guide also constrains the valve movement to a straight up and down motion. In ACOFE, two staggered bellows constrain the connecting rod to a semi-straight up and down motion, and therefore eliminate the need for the cylinder. Two other smaller bellows constrain a valve to a semi-straight up and down motion, and therefore eliminate the need for the valve-guide.
