Abstract
A piston ring for a reciprocating compressor is disclosed, including a one-part annular sealing ring with an arcuate outer surface and having a gap between butt ends of the sealing ring. A joint seal seals the gap symmetrical, having two limbs that extend at both sides in the peripheral direction over an angular range of 20° to 180° and having a radially outwardly directed, arcuate limb outer face. The joint seal includes a contact part that extends at both sides in the peripheral direction and projects beyond the limbs in the axial direction. The sealing ring and the joint seal are adapted to each other such that, when assembled, the joint seal rests laterally against the sealing ring via a stop and runs along the gap and covers same in the peripheral direction.
