Abstract
Abstract An internal combustion rotary engine including a main stator casing in which a main rotor of circular cross-section is rotatably mounted, the casing and rotor combining to form two combustion chambers and two intake chambers. Three or four vanes are mounted in the main rotor so as to maintain sliding contact with the main casing. Two compressors are arranged on opposite sides of the main casing, each compressor having a compressor rotor and compression chamber. Short passages extend between each compression chamber and each intake chamber and passage means are provided for communicating each compression chamber with a combustion chamber at predetermined intervals. In operation, a quantity of fuel and air is drawn into each intake chamber by the passage of a vane therethrough and is then driven into a compression chamber by the subsequent passage of the following vane. Preferably as the mixture is driven into the compression chamber, the mixture is precompressed to a certain extent. The mixture then undergoes final compression in the compression chamber after which it is released into the adjacent combustion chamber where the mixture is ignited.
