  • the four venting holes 10 are normally open, when the ratchet rotor rotates along the circumference, the four ratchets respectively compress the exhaust gas after the above-mentioned four small chambers are detonated along the vent hole, when The four ratchets of the working exhaust ratchet rotor are respectively close to the corresponding group impellers on the working exhaust gear ratchets corresponding thereto, and the exhaust gas is completely discharged, and the exhaust stroke is completed.
  • the ratchet rotor drives the continuous output power of the center output shaft, that is, the center output shaft completes 16 strokes of intake, compression, explosion, and exhaust per 360° rotation.
  • the rotor output of these four ratchet sets is four times that of a single ratcheted rotary engine. It far exceeds the output power of an equivalent reciprocating engine. According to the advantage that the rotary engine can output high power, it can be used on large ships, high-power internal combustion engines or on military tanks and armored transport vehicles. Multiple single-cylinder four ratchets can be combined in series on the same central output shaft. Rotor-type rotary engine, if it is connected in series at different angles of 360°, its output power is the same as that of the existing multi-type engine.

Abstract

Un moteur rotatif de type à roue à cliquet selon l'invention comprend des corps de cylindres de moteur constitués d'au moins un ensemble de corps de cylindres constitués d'un corps de cylindre de compresseur d'entrée d'air (5) et d'un corps de cylindre de travail de sortie d'air (3). Un cylindre de compresseur d'entrée d'air circulaire (501) s'adapte de manière mobile à un rotor de roue à cliquet de compresseur d'entrée d'air (502) ayant au moins un cliquet. Au moins un contre-cylindre de compresseur circulaire (503) est communicant autour du cylindre de compresseur d'entrée d'air circulaire (501). Une roue à cliquet de bloc compresseur d'entrée d'air (504) est assemblée dans le contre-cylindre de compresseur circulaire (503). Le contre-cylindre de compresseur circulaire (503) est communicant avec le cylindre de compresseur d'entrée d'air circulaire (501) par le biais de la roue à cliquet du bloc compresseur d'entrée d'air (504). Un cylindre de travail de sortie d'air circulaire (301) s'adapte de manière mobile à un rotor de roue à cliquet de travail de sortie d'air (302) ayant au moins un cliquet. Au moins un contre-cylindre circulaire (303) est communicant autour du cylindre de travail de sortie d'air circulaire (301), le contre-cylindre circulaire (303) est communicant avec le cylindre de travail de sortie d'air circulaire (301) par le biais d'une roue à cliquet de bloc de travail de sortie d'air (304). Le rotor de roue à cliquet de compresseur d'entrée d'air (502) et le rotor de roue à cliquet de travail de sortie d'air (302) sont reliés par un arbre principal (1) respectivement. Le cylindre de compresseur d'entrée d'air circulaire (501) est communicant avec le contre-cylindre circulaire (303) par le biais d'un mécanisme de distribution de gaz (41).
