Abstract
A one-piece piston for an internal combustion engine, having a ring-shaped cooling channel arranged in the outer region of the piston head, is proposed, which is closed off by a ring-shaped cooling channel cover structured towards the side of the pin bosses as a support element. This cooling channel cover comprises at least two arc-shaped cover elements the outer edge of which supports the pin-boss-side face of the ring wall.
