Abstract

A piston for a reciprocating piston internal combustion engine, in which the piston top (11) is secured to the wrist pin (14) by way of two support bearings (18) independent of the piston skirt (12). The piston ring carrier (16) connected with the piston top (11) is additionally connected with the two support bearings by way of a ring-shaped support element (19). A piston with a piston top (11) results which is capable of resisting high combustion space pressures.
