Rotary internal combustion engine or pump (10) including a main body (11) having a void (15) with a peripheral wall (32, 34), a major rotor (14) having a first rotation axis (16), at least one outer peripheral wall (13) portion radially spaced from the axis and defining a bight (17) within the major rotor (14); one or more satellite rotors (12) disposed within the or each bight (17) for rotation about a second axis of rotation (18) which is coaxial with the central axis of the bight; one or more control chambers (80) being defined at any time during a work cycle by any combination of two or more of a wall of the or each satellite rotor (12), the peripheral wall of the void (15) and the peripheral wall of the major rotor (14). The engine also has a plurality of ports (30, 28) for permitting the flow of fluid to and from the control chamber (80).
