The invention discloses a piston ring, in particular to a joint type magnetic piston ring. The joint type magnetic piston ring comprises a magnetic joint, which is characterized in that the magnetic joint comprises three sections of 120-degree arc, the radii of the three arcs are the same, and the magnetism at the contacted positions of the three arcs is the same. The invention has the beneficialeffects that the bonding property of a magnet and a cylinder sleeve is good and is more uniform than that of an elastic single opening ring, therefore the cylinder sleeve is not easy to form an ellipse; after the wear of the ring and the cylinder sleeve, overlapped parts can automatically extend to fill wearing capacity, and no opening wakening air leakage exists, thereby improving the tightness,ensuring uneasy aging of lubricating oil, prolonging the service life of machine parts and improving the efficiency of heat engines.
