The invention permits the realisation of a rotary combustion engine with a complete four-phase cycle in one revolution, and with a very simple mechanical structure. The system has four annular cylindrical chambers, the volume of which is variable according to rotation of the rotor. The four chambers are obtained by the full integration of a compressor and a motor, both rotary and with vanes: one divisory wall separates the motor section from the compressor one. Each of these two sections is further divided in two chambers with volume variable, by means of a statoric switchable vane (normally closed) and a rotoric fixed vane. Each chamber is assigned always to the same phase; the four phases are simultaneously in evolution in the system; a settled volume of fluid evolves along the phases, passing from one chamber to the successive one: at the end of each revolution, one settled volume completes its cycle. If the volume of the expansion chamber in the motor is equal to the volume of the intake chamber of the compressor, the system generates cycles of Otto type; if it is larger, the generated cycles are of Lenoir type, and the power utilization in the system is better. It is possible to realize more complete cycles in one revolution.
