    摘要： The invention relates to a piston (1) of an internal combustion engine, made of a lower part (2) and an upper part (3), having a piston base (17), which is exposed to at least one combustion jet, and a cooling channel (9), in which a separating element with at least one opening (16) is positioned. At least one pressure chamber (12) is provided below the at least one opening (16), said pressure chamber being filled with pressurized oil, and the opening (16) is designed such that the oil is continuously injected into the cooling channel (9). The separating element is designed as a cooling oil ring (20, 50, 80), and the cooling oil ring (20, 50, 80) has a height (H
    1 ) which equals at least half of the total height (H
    2 ) of the cooling channel (9).

    摘要： The invention relates to a method for producing a cooling duct piston (1) for an internal combustion engine, said cooling duct piston (1) having a cooling duct (3) in its piston head (2), wherein the piston head (2) is adjoined by a piston bottom part (4) having piston bosses (5), pin bores (6) and piston skirts (7), wherein first of all a piston blank (1') having a circumferential collar (9) that protrudes radially in the region of the piston head (2) and having an abutment region (11) for the collar (9) in the transition region (10) between the piston head (2) and the piston bottom part (4) is produced, wherein the collar (9) is subsequently reshaped such that the outer radial circumferential edge (12) thereof comes virtually or completely into abutment with the abutment region (11). Provision is made according to the invention for at least a region of the piston blank (1') to be plastically deformed shortly before or after abutment, such that the collar (9) and the abutment region (11) are connected together so as to be detachable to a limited extent or non-detachable, with the result that a completely closed cooling duct (3) is formed. Furthermore, the invention relates to a cooling duct piston (1).
