ABSTRACT:
A hinge valved rotary engine has separate compression and expansion chambers with respective smooth surfaced compression and expansion rotors mounted therein on a common engine shaft. The chambers are connected by a combustor unit which receives compressed air from the compression chamber, mixes fuel with the air, and ignites the mixture for communication to the expansion rotor to turn the shaft. Air is compressed by cooperation of a hinged compression valve which sealingly engages the compression rotor. A combustion valve is forced into sealing engagement with the expansion rotor by the pressure of the combustion gases such that the pressurized combustion gases force lobes of the expansion rotor to rotate. A tangentially vaned compressed air control valve in the combustion unit controls the timing of the release of the compressed air into the combustor unit. Tangentially vaned expansion rotor lobe seals are urged into contact with the peripheral surface of the expansion chamber by springs, by centrifugal force, and by exposure to the pressure of combustion gases in the expansion chamber.
