摘要： A compression piston ring includes a ring gap defined by facing first and second end faces; a ring back situated diametrically opposite the ring gap; first and fourth quadrants extending from opposite sides of the ring gap and second and third quadrants extending from opposite sides of the ring back to the respective first and fourth quadrants. The first end face is situated in the first quadrant and the second end face is situated in the fourth quadrant. The wall thickness of the compression piston ring is reduced exclusively in the first and fourth quadrants.

摘要： An oil scraper piston ring includes an inner circumferential surface; an outer circumferential surface adapted to contact and slide along an inner wall of an engine cylinder; a radial wall thickness defined by a radial distance between the inner and outer circumferential surfaces; and a plurality of circumferentially distributed recesses each extending radially from the inner circumferential surface toward the outer circumferential surface to reduce the radial wall thickness. Each recess has a first recess region open at the inner circumferential surface and extending radially toward the outer circumferential surface and a second recess region merging into the first recess region. The two recess regions have different shapes, and the area of the second recess region is larger than the area of the first recess region.
