摘要： A piston ring includes a piston ring body and a surface coating film formed on at least one of upper and lower surfaces of the piston ring body. The surface coating film comprises a heat-resistant resin and a metal powder contained in the heat-resistant resin, and a phosphate coating film is formed, as base coating film of the surface coating film, on a surface on which the surface coating film of the piston ring body is formed.

摘要： A three-piece oil ring and a combination of the three-piece oil ring and a piston, those capable of realizing improved sealing property and reduction in lubrication oil consumption with avoiding generation of sticking even at low tension and thin width of the ring. The three-piece oil ring includes a spacer expander 10 and two side rails. The spacer expander has a radially inner end portion provided with seating tabs 13 protruding in an axial direction and having radially outer inclined surfaces for urging inner peripheral surfaces of the first and second side rails. The spacer expander has a radially outer end portion provided with side rail support portions 14 projecting in the axial direction for supporting axial end faces of the first and second side rails. A seating tab angle of the outer inclined surface relative to an axis is in a range of 10 to 20 degrees, and a ratio of 2X/Y is in a range of from 0.04 to 0.15 where 2X is a total projecting length of the side rail support portions in the axial direction, and Y is a distance between distal end faces of the seating tabs in the axial direction.
摘要翻译： 三片式油环和三片式油环和活塞的组合，能够实现改善的密封性能和减少润滑油消耗，同时即使在低张力和薄的环形宽度下也避免产生粘附。 三件式油环包括间隔件膨胀器10和两个侧轨。 隔离物扩张器具有径向内端部，其设置有沿轴向突出的座接片13，并且具有用于推动第一和第二侧轨的内周表面的径向外倾斜表面。 隔离物扩张器具有径向外端部，该径向外端部设置有沿轴向突出的侧轨道支撑部分14，用于支撑第一和第二侧轨道的轴向端面。 外倾斜面相对于轴的座位角度在10〜20度的范围内，2X / Y的比例在0.04〜0.15的范围内，其中2X是侧轨的总突出长度 支撑部分在轴向方向上，Y是座位翼片在轴向方向上的远端面之间的距离。

摘要： A piston ring includes a piston ring body and a surface coating film formed on at least one of upper and lower surfaces of the piston ring body. The surface coating film has a most outside surface layer including a heat-resistant resin and a metal powder contained in the heat-resistant resin and a base bottom layer formed nearest the piston ring body and including a heat-resistant resin. The base bottom layer may also include a metal powder.
