ABSTRACT:
A rotor provided in a cylindrical rotor holding bore in a housing is supported rotatably in the holding bore via a shaft member extending coaxially with the rotor holding bore, and the rotor has one projecting portion, a gently inclined curved pressurization surface and a steeply inclined curved pressure reception surface. The rotor housing is provided therein with first and second swinging vane mechanisms positioned substantially on both sides of the shaft member, and a suction chamber, a compression chamber, a combustion chamber and an exhaust chamber, the capacities of which vary in accordance with the rotation of the rotor, are formed via these projecting portions of the rotor and first and second swinging vane mechanisms. An auxiliary combustion chamber is opened and closed by and with a first swinging vane, and a suction port is opened and closed by a second swinging vane, whereby a compressed gaseous mixture in the compression chamber is introduced into the auxiliary combustion chamber via a rotary valve in a shaft type portion of the first swinging vane and ignited therein, the auxiliary combustion chamber being then opened to inject a combustion gas into the combustion chamber.
