A closure element is provided to close the cooling channel in a direction away from the piston bowl. At least one guiding element is arranged in the cooling channel. The at least one guiding element provides a lug facing in a direction of an inner cooling channel wall and disposed at least partially circumferentially. The lug of the at least one guiding element is structured and arranged to direct cooling oil present in the cooling channel towards an upper region of the inner cooling channel wall relative to the closure element to facilitate cooling the upper region.
