  • Piston ring and piston ring/piston combination with improved wear properties
    Patent number: 11578799
    Abstract: A piston ring with improved wear properties has a running surface, an upper ring flank, a lower ring flank, and an inner surface. The piston ring has a radius R, and wherein in a radial section, a running surface contour includes an upper region, a central region, and a lower region. The upper region of the running surface contour has a curvature radius Ro, which lies between the ring radius R and infinity. The central region of the running surface contour has a curvature radius Rm, which lies between the ring radius R and infinity. The lower region has a curvature radius Ru, which is smaller than the ring radius R.
