Abstract
A rotary engine includes a housing having a cylindrical internal surface on which seals are supported to prevent the flow of gases from spaces between two rotating pistons on separate but concentrically-arranged shafts. Three sets of gearing control relative rotation of the pistons which move toward and away from each other to compress gases between the pistons. A drive shaft is connected by the first gear set to a first of the concentrically-arranged shafts. The drive shaft is also connected by a second gear set to the other of the concentrically-arranged shafts. The third gear set, comprised of non-circular gears, connects the drive shaft to an output shaft.
