An apparatus for controlling epicyclic motion of a rotor in a rotary engine is disclosed. The apparatus comprises: an internal gear secured to said rotor; an eccentric mounted within the rotor and adapted to rotate therein, the drive shaft extending through the eccentric and being permitted to rotate within the eccentric; an external gear secured to the drive shaft and adapted to mesh with the internal gear; and means for synchronizing the rotational movement of the rotor to permit the rotor to rotate within the engine chamber, the speed ratio of the angular velocity of the eccentric to the angular velocity of the rotor being equal to the number of symmetrically spaced-apart lobes. Due to the controlled motion of the rotor within the chamber, the rotor tips may be provided with slidable vanes which contact the circumferential wall of the chamber due to centrifugal forces acting on the slidable vanes. The apparatus may be adapted for use in rotary internal combustion engines, hydraulic pumps, compressors and the like where there may be any number of lobes on the rotor.
