    摘要: A piston ring has an annular base body 2, which is preferably open at a joint, with a U-shaped cross section, the open side of which faces inwards in the radial direction. A ring spring 4 is provided which runs in a meandering manner in the axial direction, and which pretensions the base body 2 outwards in the radial direction. In one section of the ring spring 4, which is located inside the base body, meandering loops 5 bear alternately against the shanks 3 of the U-shaped cross section. In one section of the ring spring 4, which protrudes out of the base body 2, meandering loops 6 bear alternately against the radially inwardly facing edges of the shanks 3 of the U-shaped cross section.

    摘要: A sliding element, in particular a piston ring has an outer circumferential running surface of the piston ring, has no nitriding layer, preferable no surface hardening the running surface has as an outermost layer, which differs from the intermediate layer, a DLC layer or a metal-based nitride layer, preferable a metal nitride layer, preferably a CrN layer. Provided between the substrate of the sliding element and the DLC layer there is at least one metal-containing intermediate layer, preferably a metal layer, particularly preferable a chromium layer, and at least one further surface of the sliding element, preferably the piston ring flanks, is surface-hardened, preferably has a nitriding layer.

    摘要: An oil scraper piston ring, includes a base body that has a running face region provided with running lands, an inner circumferential surface, upper and lower flanks, and oil drainage boreholes/slots extending between the running lands up to the inner circumferential surface. Manufacturing steps to produce the oil scraper piston rings are performed in a plurality of oil scraper piston ring blanks mounted on the same round mandrel.

    摘要: A piston ring having an outer running face, two flanks and an inner circumferential face is provided, the running face of which has profiling with a groove. The groove is arranged between two running face sections in relation to the cross section of the piston ring. The two running face sections are spaced apart from each other and substantially convexly curved and each have an apex. The groove has a periodically varying depth and a periodically varying width, and the number of periods of the course of the depth and the number of periods of the course of the width are equal.
