The piston comprises a piston body which extends along the central axis. The piston body includes an upper portion and a lower crown crown. And an upper crown portion includes an upper combustion wall, and a top of at least one annular rib with a free end for hanging on the upper side combustion wall. The lower crown portion including an internal passage that includes a lower layer of the at least one rib extending in at least one of the annular free end fixed to the upper ribs and the upper radially extending with respect to at least one of the lower rib. The upper crown portion including the free end to the upper pole hanging in the upper combustion wall along the central axis. The lower crown part having a lower pillar extending upwardly from the free end along the center axis of the inner passage layer. With this, the upper pole and the lower pole forms a labyrinth passage.
