Claims (1)

[Scope of Claim for Utility Model Registration] (1) A suction air rotor having vanes is rotatably mounted in a hollow interior, and a suction air chamber and an intake hole for sucking a mixed gas of liquid fuel, air, etc. An intake air housing including a delivery passage for sending out a mixed gas; an expansion/exhaust rotor having vanes and an air supply recess rotatably mounted in the hollow interior; an intake passage for introducing an expansion/exhaust chamber and the mixed gas; an expansion/exhaust housing having an exhaust hole for combusted exhaust gas; and an expansion/exhaust housing fixedly installed between the intake air housing and the expansion/exhaust housing, the delivery passage of the intake air housing and the inlet passage of the expansion/exhaust housing. an airtight compression housing in which only an air supply passage communicating with the intake air is opened; a compression chamber including the delivery passage, an air supply passage, an intake passage, and an air supply recess; a main shaft that is pivotally supported by a housing and an expansion/exhaust housing and is fixed at a predetermined position so as to integrally rotate the intake air rotor and the expansion/exhaust rotor; and an ignition provided for the air supply recess of the compression chamber. an internal combustion engine comprising means, the intake air housing elastically mounting a set of two vanes so as to protrude outward along one diameter of the intake air rotor; The air supply chamber is formed by expanding the diameter of the range from the intake hole to the intake passage, and the rest has an inner diameter approximately equal to the diameter of the intake air rotor, and the expansion and exhaust housing is a set of two pieces. The vanes of the expansion/exhaust rotor are mounted so as to protrude outward along one diameter of the expansion/exhaust rotor, and the expansion/exhaust chamber is expanded in diameter from an expansion start point provided near the ignition means to the exhaust hole. Immediately after one vane of the intake air rotor reaches the maximum compression point, the air supply recess of the compression chamber is The vane of the expansion and exhaust rotor reaches the expansion start point at the same time as being isolated from the inlet passage, and the ignition means ignites the compressed mixed gas in the air supply recess. The basic structure of a rotary engine. (2) The air supply recess has a cross-sectional shape of an appropriate length along each circumferential surface on the two circumferential surfaces between the two vanes of the expansion/exhaust rotor, and the front end of each air supply recess is The basics of the rotary engine according to claim 1, wherein the rear end of the air supply recess remains in the exhaust hole when the engine approaches the entrance passage, and the exhaust gas remaining in the air supply recess is scavenged with the compressed mixed gas. structure. (3) The basic structure of a rotary engine according to claim 2, wherein the inlet passage has a scavenging notch near the exhaust hole. (4) The compression chamber includes the delivery passage, the air supply passage,
2. The basic structure of a rotary engine according to claim 1, wherein a suitable compression ratio is set by adjusting the total volume of the inlet passage and the air inlet recess.
