ABSTRACT:
A composite piston for use in the cylinder of a diesel engine has coaxial first and second sections and a piston pin which articulately connects the sections to each other and to the piston pin bushing of the connecting rod. The first section has a round head and two piston pin bosses which are connected to the head by a hollow frustoconical portion of the first section. The bosses are reinforced by two walls each of which is integral with each boss. The walls are mirror symmetrical to each other with reference to a plane which includes the axes of the piston pin and of the composite piston. The inner sides of the walls are cooled by sprays or streams of a liquid coolant which flows through apertures provided in the walls close to the frustoconical connecting portion and serving to permit the coolant to thereupon flow along the outer sides of the respective walls. The reinforcing walls prevent the bosses from creeping away from each other in the axial direction of the piston pin or to be tilted relative to the pin and to thereby exert excessive presssure against those portions of the pin which are adjacent the outermost portions of the openings in the bosses.
