Abstract:
An internal combustion rotary engine includes a stationary, centrally located manifold having an intake and an exhaust port. Inner and outer rotor assemblies are provided which rotate in a common direction about the centrally located manifold. Each of the inner and outer rotor assemblies includes two pairs of diametrically opposed pistons, generally of octagonal shape which divide a rotating internal volume, defined by the outer rotor assembly, into four working chambers. Pistons of the inner rotor assembly slide along related walls of the outer rotor assembly and by this arrangement, the four working chambers communicate periodically with the intake and exhaust ports. Angular movement of the inner rotor assembly against the outer rotor assembly ensures that each working chamber is at minimum volume and at a maximum volume four times per revolution of a crankshaft of the engine. When diametrically opposed working chambers are at their maximum volume, the two other diametrically opposed working chambers are at their minimum volume. Movement of the rotor assemblies and transfer of forces generated during operation of the engine is accommodated by a force transmitting mechanism.
