ABSTRACT:
A rotary internal combustion engine comprising a cylindrical housing with end walls, a rotating cylinder block therein having seals mounted on the outer arcuate surface of the rotating cylindrical block as well as the end surfaces thereof to provide a tight seal with the inner walls of the housing. A plurality of radially extending cylinders are provided in the rotating block, each including a piston. Connecting rods are eccentrically mounted on a single throw or single connecting pin of a crank shaft. The cylinders are offset about one-half inch axially of the crank shaft so that they reciprocate in substantially the same plane. Different sun gear arrangements are provided to enable rotation of the rotating block either in the same direction or in an opposite direction relative to the crank shaft to obtain different ratios and different numbers of power strokes per revolution of the cylindrical bloc. Either two pistons 180.degree. apart or three pistons 120.degree. apart are provided. In one modification, the rotating block merely oscillates relative to two radially extending, stationary partitions 180.degree. apart within the housing which, together with a crank assembly, converts oscillations to rotation of an output shaft.
