| description | The invention relates to a piston ring of a reciprocating piston internal combustion engine, comprising a ring body with an open abutment, a radially outer running surface side, a radially inner circumferential side, two axially opposite flank sides, an at least partial coating (B) on the running surface side, and a circumferential recess (A) in the lower region of the running surface, said recess ending outside of the abutment region (C). The running surface side has a spherical profile with a pivot point which is arranged at a height h2 of 55-80% of the axial height h of the piston ring. |
