Abstract:
Disclosed is a monoblock or cooling channel piston and a method for producing a monoblock piston for use in an internal combustion engine. A piston blank includes a circumferential collar protruding radially in the region of the piston crown is first produced and the collar is then shaped. A contact region on a top region of the piston skirts and the collar is shaped such that the outer circumferential edge thereof points at a distance to the contact region and forms a defined gap. The gap is then sealed by a closure element in order to form a closed cooling channel.

Claim (Index 1):
A method for producing a cooling duct piston for an internal combustion engine, which cooling duct piston has a cooling duct in its piston crown, the piston crown being adjoined by a piston lower part with piston bosses, pin bores and piston skirts, a piston blank having a circumferential collar which projects radially in the region of the piston crown first of all being produced, and the collar subsequently being reshaped, characterized in that a bearing region is provided on an upper region of the piston skirts, and the collar is reshaped in such a way that the outer circumferential edge points toward the bearing region at a spacing defining a gap, the gap subsequently being closed by way of a closure element, in order to form a closed cooling duct.
