<p>A rotary piston engine comprising two segregated body chambers of compression (10) and expansion (20), and one separable combustion chamber (31), carrying out air suction and compression, combustion resultant expansion and exhaust, and fuel injection and constant-volume combustion process without any valve respectively: the compression (10) and the expansion chamber (20) both are arranged parallel adjacent to each other, each are formed by two partially overlapped body-bores provided respectively with cylindrical hubs at respective centers thereof, each have a pair of screwed rotors (11, 12, 21, 22) rotatably mounted on said respective hubs, and both communicate to each other by the combustion chamber and gas passageway means; it is characteristic in configuration that the closed space made by rotor projecting portions are progressively changed in geometry as rotors rotate, and that exhaust gases make no explosion noises.</p> |
