Sealing structure and method of mounting piston ring structural body for use in the sealing stucture |
摘要 |
The present invention provides a sealing structure employing a piston ring structural body of a type wherein an outer ring continuously formed of a resinous material is pressed radially outwards by a metal coil expander via a metal inner ring provided with an abutment. The piston ring structural body has a construction wherein the outer ring continuously formed of polyimide is pressed radially outwards by the coil expander via the steel inner ring provided with the abutment. A sliding face of the outer ring, which slides on a cylinder wall, is divided by a groove into upper and lower sliding faces, whose respective upper edge portions are provided with chamfers.
