An internal combustion engine has a rotor and a vane extending slidably through the rotor in a transverse direction for rotation therewith. The vane has opposite ends extendable beyond the rotor. A stator has a hollow, cylindrical interior. The rotor is rotatably received within the interior. The stator has opposite side walls with circumferentially extending depressions therein. The depressions are shaped to slidably receive the ends of the vane in sealing contact. The depressions of the opposite walls are staggered, causing transverse reciprocation of the vane as the rotor is rotated.
