Abstract
An engine comprises a compression portion and a combustion portion. The compression portion comprises twin-screw rotors, male engaged with female. The combustion portion comprises twin-screw rotors, male engaged with female. The male compression rotor and the male combustion rotor share a same longitudinal axis, and the female compression rotor and the female combustion rotor share a same longitudinal axis. A combustion plate is disposed between the compression portion and the combustion portion, and prevents flow of gas from the compression portion to the combustion portion, except through a small orifice centrally located on the combustion plate. A valve is affixed to the male rotors adjacent to the combustion plate, covering the lobes of the male rotors and extending beyond the lobes of the male rotors. The valve controls the flow of gas from the compression portion to the combustion portion.
