ABSTRACT:
A triangular piston is journalled rotating in a planetary manner upon an eccentric of an eccentric shaft journalled in a housing of a rotary piston internal combustion engine of trochoidal type of construction with a fluid cooled system in the housing with a multi-arcuate casing runway surfacing of which the side walls have the eccentric shaft passing therethrough. An eccentric bearing is cooled directly by a cooling medium conveyed via a bypass of the cooling system of the housing branched off from the cooling system and the cooling medium is conveyed via hollow spaces in the eccentric shaft into a location at the eccentric journalling the triangular piston. The cooling medium is supplied and carried away via lines opening into an annular groove extending around the eccentric in a location below and radially inwardly of the eccentric bearing. A supply line is provided in the eccentric shaft for supply of cooling medium to the annular groove and this supply is continuously in connection and in communication with at least one radial bore to the annular groove in a region of the eccentricity maximum of the eccentric and in a region of the eccentricity minimum of the eccentric there is arranged at least one bore leading back from the annular groove, which latter groove opens into an axial return flow line in the eccentric shaft and that furthermore the feed and return lines are connected to the bypass of the cooling system of the housing.
