    Abstract: Liquid-cooled rotary piston internal combustion engine with a housing consisting of at least one annular shell with interior guideway and two parallel end pieces, and bounding an interior space. The shell and end pieces containing cavities for circulation of two cooling circuits completely separate from each other. One of the circuits cools the region of the housing in the hot arc of the shell, where the ignition, expansion and exhaust strokes take place in the interior space. A liquid-cooled piston revolves in the housing. The cooling circuit of the piston and the shell cooling circuit traversing the region of the hot arc are connected in series.
