Abstract: A rotary internal combustion engine with the rotor having separate power and compressor sections in side-by-side relation secured to the same shaft so that they rotate together and are separated by a separating plate. These sections have, at their outer periphery, members that move laterally into engagement with the wall of the stator within which the rotor rotates. The separating plate rotates with the rotor sections and has an opening through which a compressed gas charge is conveyed from the compressor section into the power section.

Abstract: A rotary internal combustion engine wherein the compression and the power functions are produced by a single rotor with the compression function being achieved by means of vanes that move longitudinally of the axis of rotation of the rotor and cooperate with complimentary recesses and with the power function being achieved by means of members that move laterally of said axis of rotation and cooperate with the periphery of the stator.
