Abstract
A piston for an internal combustion engine may include a piston head and a piston skirt. The piston head may include a circumferential ring part. In a region of the ring part, the piston head may include a circumferential cooling channel and a circumferential ring support. The ring support may define a wall section of the cooling channel and thereby be directly in contact with the cooling channel. The cooling channel may have a cross-section that may define a contraction disposed in a central area.
