Rotary engine

A rotary engine, comprising an engine body having a cylindrical chamber, the cylindrical chamber including end walls,

• an oval rotor comprising a main body, said main body having a pair of opposed side walls and an outer peripheral surface, and a pair of opposed shaft members extending outwardly from a respective side wall, said shaft members being axially aligned relative to each other and extending through a respective end wall of the cylindrical chamber to allow the oval rotor to exhibit rotary motion about a central axis,
• a plurality of moveable vane members extending between the peripheral surface of the rotor and an internal wall of the cylindrical chamber to define a plurality of separate combustion chambers, the vane members being supported by a housing which forms the cylindrical chamber, characterized in that the rotor has an exhaust pathway extending through only one of said shaft members and through the main body of the rotor and to an exhaust port in the peripheral surface of the rotor to allow exhaust to pass from the exhaust port to the exterior of the cylindrical chamber, and an inlet pathway extending through one of said end walls of the cylindrical chamber and spaced from the pair of opposed shaft members, the inlet pathway extending through the main body of the rotor to an inlet port in the peripheral surface of the rotor to allow inlet fluid to pass from the exterior of the cylindrical chamber to the inlet port, the exhaust and inlet flow pathways being separate from each other.
