Abstract

Improved piston for internal combustión engines, light alloy (1) comprising an upper part (2), a skirt (4) pair of piston pin supports (6) that are formed by two widened parts of the skirt (4) ) extending from the upper part (2), characterized in that none of the enlarged parts has a decompression groove (9) that extends substantially in a plane perpendicular to the common axis of the supports (6) along the extension of the inner surface (7) of the skirt (4) from which the flared portions protrude, and in that each of the decompression grooves (9) extends from this part (10) of the outer surface of the respective support ( 6) that is s away from the upper part (2) to a plane substantially coincident with the plane perpendicular to the axis of the piston (1) containing the axis of the supports.
