ABSTRACT:
The rotary-piston engine of U.S. Pat. No. 3,736,080 has two sets of pistons rotatable about a common axis in a casing. One set is attached to the output shaft of the engine for continuous rotation with the same while a motion-transmitting train connects the two sets in such a manner that the pistons of the other set are rotated at cyclically varying speed to expand and contract combustion chambers circumferentially bounded by respective pistons of the two sets. The motion-transmitting train includes crankshafts excentrically mounted on the output shaft and driven by planet gears meshing with an internal ring gear on the engine casing, and connecting rods linking each crank with the second set of pistons. According to this invention, the engine includes a central gear coaxial with the ring gear, meshing with the planet gears, and driving a second output shaft coaxially rotatable in the first-mentioned shaft.
