Abstract

A rotary engine has a rotor that has rockers pivoting in chambers. As each rocker pivots, it rotates an outer crankshaft. Each outer crankshaft has a spur gear that engages a stationary ring gear. Spur gear rotation causes the gears and the outer crankshafts to revolve around the ring gear. This cause the rotor to rotate. As the rotor rotates, successive chambers are positioned at the intake, compression, ignition, and exhaust positions. Igniting the fuel in the ignition position pushes the rocker inward to rotate the outer crankshaft associated with that rocker to cause the rotor to rotate.

11. The rotary engine of claim 2 wherein each rocker has a surface facing the inner surface of the housing, the surface having a central section and a squish section at least partially around the central section and having a surface raised from the central section.

12. The rotary engine of claim 2 wherein each rocker has a groove extending at least partially around the rocker and a sealing member seated in the groove.

25. The rotary engine of claim 6 further comprising a spark plug through the housing for creating a spark in the housing for igniting an air/fuel mixture containing the air-fuel mixture is positioned such that the spark can ignite the air-fuel mixture, the rocker in the chamber moving toward the housing to compress an air-fuel mixture before the spark plug ignites the air-fuel mixture in the chamber containing the air-fuel mixture.

9. The rotary engine of claim 6 further comprising a spark plug through the housing for creating a spark in the housing for igniting an air-fuel mixture when the chamber containing the air-fuel mixture is positioned such that the spark can ignite the air-fuel mixture.
