Abstract: A rotary internal combustion engine has a cylindrical rotor eccentrically mounted within a circular cavity in the stator, the rotor being formed with a central axial fuel mixture inlet passageway and with a plurality of radial cavities in which are slidably mounted piston vanes, the crowns of which protrude from the rotor and are biased into closely spaced relation with the periphery of the block cavity to form therewith sealed compression-combustion chambers in the crescent-shaped spaces between the rotor and periphery of the block cavity. Sealing elements closely spaced from the block cavity periphery bisect the piston vane crowns in planes coincident with the rotor axis and each piston vane is formed with a pair of intake valves disposed respectively fore and aft of the sealing elements and sequentially operable to pass fuel mixture from the central inlet passageway into the combustion chambers defined within the crescent-shaped spaces by a pair of adjacent pistons and thereby materially increase the volumetric efficiency of the engine as compared with engines of the prior art having only a single inlet valve per combustion chamber. In one embodiment, wiper bars engageable with the block cavity surface are resiliently mounted in the piston crown so as to maintain a tight seal against the periphery of the block cavity while yieldably spacing the piston crown rings therefrom.
