Abstract:
1. A rotary engine comprising at least: a casing having an inlet port for admitting combustion air, a combustion chamber, and an exhaust port for expelling the burnt air/fuel mixture; an ignition plug mounted in said casing; a first rotor-piston rotatably fitted in said casing; a second rotor-piston rotatably fitted in said casing, the first rotor-piston and the second rotor-piston having a common axis of rotation; a first power shaft rotatably mounted on said casing, the first power shaft is disposed at one end of the two rotor-pistons, a rotation axis of the first power shaft is inclined to the common rotation axis; a second power shaft rotatably mounted on said casing, the second power shaft is disposed at the other end of the two rotor-pistons, a rotation axis of the second power shaft is inclined to the common rotation axis, the rotation axis of the first power shaft, the rotation axis of the second power shaft and the common axis of rotation are coplanar, the inclination of the rotation axis of the first power shaft relative to the common rotation axis is equal to the inclination of the rotation axis of the second power shaft relative to the common rotation axis; a fork of the first power shaft is connected by a cross to the first rotor-piston, a second fork of the first power shaft is connected by a cross to the second rotor-piston, centers of both crosses are on the point where the common rotation axis and the rotation axis of the first power shaft intersect; a fork of the second power shaft is connected by a cross to the first rotor-piston, a second fork of the second power shaft is connected by a cross to the second rotor-piston, centers of both crosses are on the point where the common rotation axis and the rotation axis of the second power shaft intersect; wherein the angle of rotation of the first power shaft about the rotation axis and the angle of rotation of the second power shaft about the rotation axis remain equal by the crosses that connect the first and second power shafts with the first and second rotor-pistons to reduce inertia vibrations of the rotary engine, loads on bearings of the rotor-pistons, and load carried by each of the crosses connected to the first rotor piston and the second rotor-piston to the fork of the first power shaft; and by each of the crosses connected to the first rotor piston and the second rotor-piston to the fork of the second power shaft.
