Abstract (en)
[origin: WO2005103473A1] The invention relates to a cooling channel covering for a piston (8) of an internal combustion engine in the form of a spring steel sheet (1) which is measured in such a manner that wear and tear in the region of the surface (9) is prevented, in such a manner that a peripheral gap (12) is produced between the radial, external front side of the spring steel sheet (1) and the radial, external limit of the step-shaped recess (19).
