摘要：
The piston for an internal combustion engine, consisting of a piston head (1) and a body (2) of monobloc or two-piece construction, the head bearing upon the body (2) via at least two circular bearing surfaces (4, 5), the body (2) having a bearing part (6) receiving an articulation part (10) rigidly attached to the end of a connecting rod (3) and said bearing part (6) having on its piston head side a wall (7) forming a bearing whose bearing surface (8) is continuous, is structurally lighter in that the portion of its body (2) connecting the wall (7) to the bearing surfaces (4, 5) is formed of at least two thin, truncated conical partitions (11, 12) whose center lines (13, 14, 15, 16) are rectilinear, each of said partitions bearing upon a separate one of the circular bearing surfaces (4, 5).
