An internal combustion engine having a fixed casing or housing defining a cavity of circular cross section, and cam mechanism within the cavity near the center thereof. A rotor rotates in the annular space between the casing and the cam, and carries flaps which are moved by the cam mechanism as the rotor rotates, to form, in conjunction with the end walls and cross members of the rotor and the interior surface of the casing, combustion chambers of varying size. At one point in the cycle of rotation, the flaps of one chamber move to a position forming a rather large intake chamber, which receives a combustible mixture. Then, as rotation continues, the flaps are moved to make this chamber smaller to compress the combustible mixture; then the mixture is ignited, producing pressure within the chamber, which exerts force in a direction to cause the rotor to rotate relative to a fixed part of the cam mechanism; then the cam mechanism moves the flaps to decrease the size of the chamber to assist in exhausting the products of combustion; and finally as rotation continues to an inlet port, additional movement of the flaps allows entry of a fresh supply of the combustible mixture. Several embodiments are illustrated and described.
