Abstract
The invention relates to a sealing ring for sealing a piston rod of a piston compressor. The sealing ring comprises three segments, wherein the segments have portions extending in the circumferential direction of the sealing ring, which form an overlapping joint. The overlapping joint brings about an excellent sealing effect in the axial direction.
