Abstract
A rotary internal combustion engine has a housing with an elliptical inside surface surrounding an elliptical rotor forming with the housing combustion chambers. Valve and ignition assemblies connected to a source of air under pressure and injectors for introducing fuel into the air supply sequentially allows the air and fuel mixture to flow into the combustion chambers and ignite the air and fuel mixture therein. Vane and seal assemblies on the rotor and housing are controlled with cam and linkages to provide positive effective gas seals between the housing and rotor. A slack adjuster maintains lateral sealing relationships between the housing vane and seal assemblies and opposite side walls of the housing.
