グ。 In a piston ring that is fitted into a ring groove of a piston of a reciprocating gas compressor, the piston ring is formed into a self-expanding type piston ring that is biased so that the gap at the abutment part thereof widens. A backup member is fixed to the inner peripheral surface of one end of the abutment, and the backup member is formed in a length that can cover the abutment and its vicinity to prevent gas leakage from the abutment. Piston rings for reciprocating gas compressors.
