ABSTRACT:
A rotary piston internal combustion engine of trochoidal type of construction with a piston slidably journalled and controlled via a synchronous transmission gear drive unit. An eccentric bearing of the piston is sealed-off on both sides of the remaining machine chambers or spaces with sealing rings located around the eccentric shaft. Circulation of the lubricating oil and cooling oil that is under pressure being delimited as to this bearing and the cooling hollow chambers of the piston with such lubricating oil and cooling oil being kept away from the working chambers and also eliminating any oil inner seals otherwise required therewith.
