摘要： The present invention relates to piston machines and, more particularly, to piston rings. The piston ring 1 has blind slots 2 and slots 5 which form channels. The blind slots 2 open on the outer surface 3 and on the face surface 4. The slots 5 are made from inside of the ring 1 and form channels which open on the face surfaces 4 and 6 and on the outer surface 3. The spaces between the adjacent slots 2 and 5 form flexible bridges.
