ABSTRACT:
A multipart piston for an internal combustion engine has a top piston part and a bottom piston part. The top piston part is provided with an externally threaded head at the end facing the bottom piston part while the bottom piston part is equipped with a support plate at the end facing the top piston part. The support plate encompasses a plate member and an internally threaded element into which the threaded head is screwed. The plate member is joined to the bottom piston part via a connection zone in such a way that the bottom end of the threaded element lies below the bottom end of the connection zone relative to the longitudinal axis of the piston.
