Abstract (en)

[origin: DE102005061075A1] The piston (1) has an annular section on a radial outer surface close to the bottom of the piston, a shaft following the annular section in the direction away from the bottom, two opposing bolt hubs (7) with hub bores (8) held by the shaft, an annular cooling channel (9) for cooling the annular section connected to the piston's interior via an oil supply channel and an oil outlet channel and at least one hub cooling channel (13). Hub cooling channels arranged in the bolt hub regions close to the bottom of the piston are each connected to the cooling channel. An independent claim is also included for a method of manufacturing an inventive device.
