Abstract
A compression ring for an internal-combustion engine includes an outer circumferential surface and a lower circumferential surface which define a lower outer circumferential corner, a radially extending first butt end face having a circumferentially projecting rib, and a radially extending second butt end face opposing the first butt end face and having a circumferentially extending notch for receiving the rib. The lower outer circumferential corner portion has a cut-away portion extending along the entire circumference thereof except at portions contiguous to the first and second butt end faces.
