In rotary piston engines invented by H.Walker of New Zealand, rotation not only gives rise to compression-expansion cycle necessary for combustion but also external pumping action forces air past rotor to cool it, and then into carburetor, so that induction gases are forced into combustion chamber under pressure; thin cylinder unit that has elliptical rotor is illustrated; other design features are described.
