Abstract (en)
[origin: WO2012083929A2] The invention relates to a piston (10, 110, 210) for an internal combustion engine, comprising a first piston component (11) and a second piston component (12), wherein the first piston component (11) and the second piston component (12) form a circumferential cooling channel (23), which is open toward the second piston component and which is closed by means of a circumferential closing element. According to the invention, the closing element (25, 125, 225) is connected to a first piston component (11) and extends radially in the direction of the second piston component (12), the second piston component (12) has a circumferential contact flange (26, 126, 226) that extends radially in the direction of the first piston component (11), and the closing element (25, 125, 225) rests on the contact flange (26, 126, 226) or the closing element (325) is supported on an end face (331) of the contact flange (326) at a circumferential bottom edge (329) of the closing element.
