Abstract
The invention relates to a cooling channel covering for a piston of an internal combustion engine in the form of a spring metal sheet which is measured in such a manner that wear and tear in the region of the surface is prevented, in such a manner that a peripheral gap is produced between the radial, external front side of the spring metal sheet and the radial, external limit of the step-shaped recess.
