Patent ID: 7707987

Claim:
An internal combustion rotary engine comprising: a stator including an inner surface defining a distorted oval-shaped cavity including an intake zone, a compression zone, an expansion zone and an exhaust zone; a rotor rotatable within the cavity, and including an outer surface, and a plurality of combustion cavities and a plurality of slots located along a periphery of the rotor; and a plurality of radially protruding and movable vanes disposed within the slots and extending to and engaging the inner surface of the stator, so as to form a plurality of rotatable chambers within which a mixture of fuel is compressed for ignition in the plurality of rotor combustion cavities; a vapor chamber overlying a portion the oval-shaped cavity and including a fluid for absorbing heat from the ignition of the fuel mixture in the rotor combustion cavities and returning heat to the combustion cavities as they rotate through the expansion zone; and an active cooling system for protecting the rotary engine from excess heat, the cooling system comprising the stator, the plurality of vanes and a cooling/heat transfer system located within the rotor.
