The invention relates to a piston (10, 110, 210, 310, 410) for an internal combustion engine, comprising a piston head (11) with at least one piston crown (12) which is exposed to at least one jet of combustion gases, and a piston shaft (17), the piston head (11) and the piston shaft (12) being configured as interconnected individual components including a peripheral outer cooling channel (27). The invention is characterized in that an annular partition wall (35, 135, 235, 335, 435) is provided in the cooling channel (27) in parallel to the piston crown (12) and has one or more nozzle-type openings (37, 45, 137, 237, 337, 437) that are arranged in such a manner that their respective outlet jet is directed against the underside (12a) of the piston crown (12). |
