<p>An internal combustion rotary engine (10) includes a stationary, centrally located manifold (220) having an intake and an exhaust port (222, 224). Inner and outer rotor assemblies (14, 16) are provided which rotate in a common direction about the centrally located manifold and include two pairs of diametrically opposed pistons (84, 100), generally of octagonal shape which divide a rotating internal volume, defined by the outer rotor assembly (14), into four working chambers which communicate periodically with the intake and exhaust ports. Pistons of the inner rotor assembly (16) slide along related walls of the outer rotor assembly. Movement of the rotor assemblies and transfer of forces generated during operation of the engine is accommodated by a force transmitting mechanism (18) which includes a crankshaft (21), a main crank member (50), connecting links (58, 60), and timing gear structure (24, 26, 36, 48). An important feature of the invention is the provision of an internally located water pump or impeller (122) driven by the crankshaft. The pistons are liquid-cooled along with housings of the inner and outer rotor assemblies.</p> |
