Abstract
A rotary engine having an annular cylinder with more than one piston drivable in rotation therein, the pistons being fixed respectively to concentric hollow shafts that are thereby independently rotated thereby around their concentric axis. Crank members, at least one per piston, are mounted in ball races that are eccentrically fixed to the respective concentric shafts, the crank members extending diametrically across their respective concentric shafts. An eccentric drive shaft displaced radially from the axis of the concentric shafts mounted for rotation in and extending through said concentric shafts, the eccentric shaft defining diametric holes for slidably engaging the crank members without loss of rotational motion while allowing the crank members to move simultaneously toward the away respectively from the eccentric shaft axis at constantly varying speeds and directions to thereby rotate the eccentric shaft. Both eccentric and concentric shafts are mountable in ball races fixed in a motor housing and the ends of concentric shafts for support of all shafts at their respective ends. As many as four pistons can be mounted in each cylinder respectively fixed to a concentric shaft…
