Abstract
A piston ring for an internal combustion engine may include an annular base body and a protective coating arranged on an outer circumference of the base body. The base body may include a first joint flank, a second joint flank, an interruption along the circumferential direction, an axial end face, and an edge formed between the first joint flank and the end face. The interruption may form a joint bounded along a circumferential direction of the base body via the first joint flank and the second joint flank. The axial end face may include a radially outer surface section extending perpendicularly to a central longitudinal axis of the base body and merging radially inwards into a radially inner surface section extending at an obtuse angle to the central longitudinal axis. The edge may include a chamfer.
