oil scraper

study on coil-spring-loaded single oil scraper ring for diesel engine

柴油机单刮油边螺旋撑簧油环的研究

First assemble the three-piece oil scraper ring.

首先装配三件式刮油环。

label and tolerance value of radical offset degree for oil scraper side of oil control ring

油环刮油边径向偏移度的标注及公差值

Although the contacting pressure of the single oil scraper ring remains unchanged, the laminated property on cylinder liner is improved and the tangential force can be reduced by 40% to 50%, and decreases the friction resistance.

新设计的单刮油边螺旋撑簧油环在接触比压保持不变的前提下，明显地改善了对气缸壁的贴合性，且油环切向弹力下降40%~50%，从而降低了摩擦阻力。
