Abstract
The disclosure is of a rotary internal combustion engine constructed in three sections, a compressor section, a combustion section and an expander section. Each of the compressor and expander sections includes male and female rotors with complementary, single turn lobe and groove in which gas, e.g. first an air-fuel mixture and then the combusted mixture, traverse the section. In a lubrication system, a shaft rotates in a cylindrical lubrication gallery. Oil is carried along a helical groove around and along the shaft to small passageways that carry the oil to the rotors of the compressor and expander sections.
