Patent ID: 8689763

Claim:
Rotary engine comprising a circular stator, a circular rotor rotating about the stator; the rotor and the stator are separated by a circular cylinder and at least one element with two flanges, wherein: said rotor comprises two compression pistons attached to the inner surface of the rotor; these two pistons are located at the two extremities of a first diameter of the rotor and kept substantially in contact with the outer surface of the stator and said stator comprises a recess at each extremity of a diameter; each recess forms a compression chamber with said compression piston positioned at the end of the recess in the direction of rotation of the rotor and one of the flanges of said element with two flanges, referred to as the cylinder head flange; the motive force is applied to said compression piston when the pressure of the gases inside said compression chamber is suddenly increased to a predefined value.
