A device for reducing leakage between a rotor and a stator of a rotary engine at low running speeds is disclosed, the device comprising sealing elements at the end parts of the rotor teeth, adapted to come into frictional engagement with the internal surface of the stator at low speeds and to be disengaged in response to centrifugal forces, when the speed exceeds a predetermined value, the engine being then operated as a conventional engine of the gear type.
