ABSTRACT:
A rotary internal combustion engine including a housing dividing a substantially circular rotor chamber and a drive shaft extending through this chamber. A circular rotor is mounted in the chamber on the drive shaft and has a diameter less than the diameter of the chamber. The rotor and drive shaft are offset from the center axis of the chamber. Two pairs of vanes are slidingly mounted in the rotor with one vane of each pair being located diametrically opposite to the other vane of the pair. Rods fixedly connect the vanes of each pair together so that the predetermined distance between outer ends of the vanes of each pair remains constant and is the same for each pair. This predetermined distance is substantially equal to the distance from a point on the circumferential wall of the chamber which is closest to the circumference of the rotor and a second point on the wall diametrically opposite the first point. A portion of each of two circumferential wall sections is slightly removed to permit full rotation of the rotor.
