FIELD: sealing above-piston space; piston compressors and piston pumps. SUBSTANCE: piston sealing member is made in form of split ring 1 which is manufactured from light alloy. Wear-resistant coat 2 is anti-friction; it is applied by microarc oxidizing of ring surface. Ratio of height of ring 1 to diameter of piston does not exceed 0.01. EFFECT: enhanced reliability of cylinder-and-piston group members. 3 dwg
