The invention relates to a compression piston ring, comprising a running surface, an inner peripheral surface, and upper and lower flank surfaces extending therebetween, wherein a slight taper < 30' having an axial height of 10-30%, with respect to the total running-surface height (H), is formed on the running-surface side in the region of the lower flank surface, which slight taper transitions into a taper that extends in the direction of the upper flank surface and that has a magnitude between 90 and 200', and wherein a thin wear-resistant layer having a thickness between 0.1 and < 20 [miu], in particular 4-6 [miu], is deposited on the entire running surface. 压缩活塞环，具有工作面、内周面以及在其间延伸的上侧表面和下侧表面，其中，在下侧表面的区域中在工作面侧加工有微角分<30'，所述微角分的轴向高度为关于所述整个工作面高度(H)的10％至30％，所述微角分过渡为朝向上侧表面的方向延伸的、为在90至200'之间的角分，并且其中，在整个工作面上沉积有薄的耐磨的层，所述耐磨的层的厚度在0.1至<20μm、尤其是4至6μm之间。
