摘要： The present invention provides a sealing structure employing a piston ring structural body (10) of a type wherein an outer ring (20) continuously formed of a resinous material is pressed radially outwards by a metal coil expander (40) via a metal inner ring (30) provided with an abutment. The piston ring structural body (10) has a construction wherein the outer ring (20) continuously formed of polyimide is pressed radially outwards by the coil expander (40) via the steel inner ring (30) provided with the abutment. A sliding face (24, 25) of the outer ring, which slides on a cylinder wall (200), is divided by a groove into upper and lower sliding faces, whose respective upper edge portions are provided with chamfers (26, 27).

摘要： The present invention aims at reducing the amount of oil consumption in a piston (1) using a piston ring (200) continuously formed of resin without being provided with an abutment. A stepped portion(31) is formed on a third land (30), which is located below a second ring having a construction wherein an outer ring (210) continuously formed of polyimide without being provided with an abutment is pressed against a cylinder wall (2) by a coil expander (230) via an inner ring (220) continuously formed of PTFE without being provided with an abutment. Oil spill ports (32) are provided so as to allow communication between the stepped portion and an inner wall of the piston.

摘要： The present invention provides a piston ring structural body (10) composed of an outer ring (20) continuously formed of a resinous material, an inner ring (30) continuously formed of a resinous material and a ring tensile force applying member (40) for pressing the outer ring radially outwards via the inner ring. The piston ring structural body (10) has a construction wherein the outer ring (20) continuously formed of polyimide is pressed outwards in the radial direction of the piston by a coil expander (40) via the inner ring (30) continuously formed of PTFE. A sliding face (24, 25) of the outer ring, which slides on a cylinder wall (200), is divided into upper and lower sliding faces, whose respective upper edge portions are provided with chamfers (26, 27). A contact portion of the inner ring that contacts the coil expander is provided with an upper inclined face (33) extending inwards and upwards and a lower inclined face (34) extending inwards and downwards. The angles of inclination of the upper and lower inclined faces range from 30° to 60°.
