Claims

[Scope of utility model registration request]

(1) A combustion chamber with an approximately elliptical cross-section having a narrowed portion, a rotor disposed within the combustion chamber so as to be rotatable around an axis passing through the combustion chamber, and a rotor rotating freely in the radial direction from the outer peripheral surface of the rotor. At least two pairs of vanes are arranged inside the rotor in front and behind each other, a running cam that controls the protrusion and retraction of the vanes as the rotor rotates, and a track cam arranged on one side of the narrow part of the combustion chamber opposite to the narrow part of the combustion chamber. The pair of vanes includes an ignition plug, and an inlet and an outlet provided on the wall of a part of the combustion chamber opposite to the ignition plug, one after the other with respect to the rotational direction of the rotor. The rotor is arranged to have the same angular spacing with respect to the axis, and the rotor has a circumferential surface between the two vanes forming the pair when the portion between each pair of vanes is in a rotational position facing the spark plug. is arranged so as to be spaced apart from the inner surface of the combustion chamber near the spark plug, and the shape of the travel cam is such that the vane is controlled to protrude and retract so that the outer edge of the vane in the radial direction is in airtight contact with the circumferential surface of the combustion chamber. A rotary engine characterized by:

(2) ``Outer cover where the travel cam closes both axial ends of the combustion chamber''
The rotary engine according to claim 1, wherein a cam follower formed on the inner surface of the member and protruding in the axial direction from the base end of each vane engages with the track cam.

(3) The rotary engine according to claim 1, wherein the entire outer circumferential surface of the rotor is separated from the circumferential surface of the combustion chamber.

(4) The rotary engine according to claim 1, wherein a recess is formed in the outer peripheral surface of the rotor between the pair of vanes.
