    • A steel oil ring assembly having an upper rail, a lower rail and an annular space-expander embraced by the rails and having radially extending or axially extending corrugations. The spacer is split at one circumferential location to form abutting end portions which come into pressured contact with each other at a force point located on a plane passing through the centers of the corrugations that extends in an axial direction for radially extending corrugations and in a radial direction for axially extending corrugations. The free ends of the abutting end portions of the spacer form an opening having an angle of 10.degree..+-.9.degree. extending outwardly from the force point.
    • 一种钢油环组件,具有上轨道,下轨道和环形空间扩张器,其包围轨道并且具有径向延伸或轴向延伸的波纹。 间隔件在一个圆周位置处分开以形成邻接端部,该邻接端部在位于穿过波纹中心的平面上的力点处彼此加压接触,该平面沿轴向方向延伸以径向延伸波纹并且在径向 轴向延伸波纹的方向。 间隔件的邻接端部的自由端形成从力点向外延伸的角度为10度+/- 9度的开口。
