Abstract
This invention relates to an internal-combustion engine of generally spherical configuration having a generally spherical rotor mounted on a rotor shaft in a generally spherical shell. Combustion chambers are formed in appropriate recesses in the rotor and the inside of the spherical shell. The recesses are bounded by fixed partitions and movable pistons between the fixed partitions so that a series of combustion chambers are formed one on each side of each piston. The pistons are each connected to a central hub at the center of the rotor, and the hub is rotatable to a limited extent in a direction perpendicular to the rotor shaft. The pistons are therefore able to sweep through limited angular motion and during each motion increase the volume of one series of combustion chambers and decrease the volume of the other series of combustion chambers. A mechanical activating mechanism is provided so that the central hub is caused to rotate in a reciprocating manner through various angular positions that are predetermined in relation to the angular position of the rotor; in this manner the piston sweeping motion is precisely linked to the angular position of the rotor. Appropriate ports and ignition components are provided so that fuel and air can enter the various combustion chambers in proper sequence, be compressed, burned and exhausted also in proper sequence.
