Abstract
A rotary device particularly useful as a rotary engine comprises a cylinder having two (or more) pairs of axially displaceable pistons, the pistons of each pair being movable towards and away from each other to define an expansible and contractable chamber therebetween. Each chamber includes fuel intake openings, exhaust openings, and spark plugs. The inner surface of the cylinder, and the outer surface of the pistons, include cooperable cam and follower means such that the displacement of the two pistons in each pair towards and away from each other also imparts a rotary motion to the pistons, the side walls of the pistons being formed with gear teeth coupling the pistons to a rotary output shaft.
