部に形成された溝に、該溝底部に圧縮工程の圧力
流体を導入する圧力流体導入路を溝の圧力室側の
側壁に形成して、溝底部に導入される圧力流体に
より上記ピストンリングを拡径させるように構成
したことを特徴とするピストンリングの溝構造。 In a groove formed on the outer periphery of the piston to fit a piston ring, a pressure fluid introduction path for introducing pressure fluid for the compression process into the groove bottom is formed on the side wall of the groove on the pressure chamber side, and the pressure fluid is introduced into the groove bottom. A groove structure for a piston ring, characterized in that the piston ring is configured to expand in diameter by a pressurized fluid.
