摘要

Pistu00e7o at various seu00c7u00d5es, for a motor combustu00e7o.The present invention relates to a piston (1) refrigerated, several sections to the combustion engine that on the lower side, out in relation to the bottom of the piston (30), in a position radially outside, has a cooling channel (10) in a format that is closed by the cover ring. The cooling channel (12) configured as a ring.The cover of the cooling channel (12) has a region (12) and a radial internal lingu00faeta (25) which penetrates into a recess (28) shaped in the lower section of the piston (6), thus avoiding the cover of the cooling channel (12) performs rotary movements on S to the piston (1) in the assembly and during operation.
