Abstract

The present engine includes a heating chamber to produce relatively high temperature, high pressure gases an intake chamber to provide relatively low temperature, low pressure gases which initially act as scavenging gases an exhaust chamber into which the spent hot gases are expelled by the scavenging gases a compressed cool gas chamber into which the compressed cool gases flow with partial expansion and at least one hot gas expansion outlet or duct into which the high pressure hot gases expand. In addition the present engine includes a compressor-expander rotor having a plurality of rotor chambers, with each of said rotor chambers having an inlet opening and a nozzle with an outlet opening. The compressor-expander rotor is disposed to rotate adjacent to said intake chamber and said heating chamber, to accept into said rotor chambers, cool gases from the former followed by hot gases from the latter. Termination of the flow of cool intake gases from each rotor chamber nozzle outlet initiates a shock wave at the rotor chamber nozzle outlet. A second, normally stronger, shock wave is initiated at the inlet of each rotor chamber as it is exposed to the hot gases flowing from the heating chamber. Each rotor chamber is designed so that before this second shock wave (which is set up by the hot gases entering a rotor chamber already filled with cool gas) reaches the end of its excursion toward the rotor chamber outlet, the shock wave encounters the constricted area, or nozzle, of the rotor chamber. As a result this second shock wave is reflected from the rotor chamber nozzle toward the inlet of the rotor chamber. As a result of this reflected shock wave, the final pressure of both the cool gases and the hot gases within the rotor chamber is very high and is substantially higher than the initial pressure of hot gases flowing from the heating chamber. The rotor housing is designed such that ideally as the reflected shock wave reaches the inlet of the rotor chamber, this inlet is sealed as a result of rotation of
