A piston ring for the piston of an internal combustion engine, comprising, on a lower side of the piston ring, a circular, radially inner bezel, the width thereof reducing, on both sides of the ring stop, up to the side of the piston ring that is opposite the ring stop, in a symmetrical manner in relation to a radially situated axis and runs through the ring stop, and the bezel on the lower side of the piston ring is arranged away from the piston base. A good oil-scraping effect of the piston ring is obtained over the entire periphery of the inner wall of the cylinder.
