  • Patent number: 12071940
    Abstract: Various embodiments of the present disclosure are directed to packing rings. In one example embodiment, a packing ring is disclosed including first and second axial ring ends, at least three ring segments, and at least three relief openings. The at least three relief openings each have a first relief opening end opening into the radially inside inner circumferential surface of the ring segment. The first relief opening ends of two relief openings arranged adjacent to one another in the circumferential direction are spaced apart from one another at a relief opening circumferential distance. The first relief opening ends are closer in the axial direction to the first axial ring end than to the second axial ring end and are spaced apart at a relief opening axial distance from the first axial ring end, which is 4% to 20% of the axial ring width of the ring segment.
