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°.
摘要翻译：本发明提供一种活塞环结构体（10），其由连续由树脂材料形成的外圈（20），由树脂材料连续形成的内圈（30）和环张力施加构件（40）构成，用于通过内圈径向向外挤压外圈。活塞环结构体（10）具有这样的结构，其中连续由聚酰亚胺形成的外环（20）通过线圈膨胀器（40）经由内部连续形成的PTFE（30）由PTFE挤压而向活塞的径向向外挤压。外环的滑动面（24,25）在气缸壁（200）上滑动，被分成上下滑动面，其各自的上边缘部分设有倒角（26,27）。所述内圈与所述线圈膨胀机接触的接触部分设置有向内和向上延伸的上倾斜面（33）和向内和向下延伸的下倾斜面（34）。上下倾斜面的倾角范围为30°〜60°。

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).
