ABSTRACT:
A rotary internal combustion engine comprising two intermeshing rotors provided with radially extending lobes and intervening grooves, the lobes of at least one of the rotors being provided with radially extending channels for supply and return of cooling liquid from and to, respectively, axially extending central channels of the rotor, said return channels being interposed between said supply channels and a heated surface portion of the lobes. The temperature difference between the cooling liquid portions in the radially extending channels being utilized for circulating the liquid under the action of the centrifugal forces arising during rotation of the rotors.
