  • Helical compression spring for an oil scraper ring of a piston in an internal combustion engine and method for coating a helical compression spring
    Patent number: 9004465
    Abstract: A helical compression spring, preferably of steel, in particular CrSi steel or CrNi steel, comprises a coating which has at least one a-C: H: Me coating or a plurality of layers of CrN (16) and a-C: H: Me coatings (14) alternately. In a method for coating a helical compression spring, preferably of steel, a plurality of layers of CrN and a-C: H: Me coatings are applied alternately.

  • Piston ring
    Patent number: 8235393
    Abstract: A piston ring having a base body, which comprises a running surface provided with at least one chamber, an upper and a lower flank surface, and an inner circumferential surface, wherein the running surface is provided with at least one PVD layer such that the same is adjusted to the contour of the running surface without completely filling the chamber, wherein the respective edge region is provided with a layer thickness, b that is reduced compared to the layer thickness, a of the chamber as a function of the configuration of the chamber.

  • Piston ring
    Patent number: 4973066
    Abstract: A piston-and-ring assembly includes a piston having a circumferential groove which has an upper side wall and an opposite lower side wall; and a piston ring received in the groove and having opposite radial faces extending obliquely with respect to the side walls. The piston ring engages, with an axial bias, the upper and lower side walls with an annular marginal surface portion forming part of each radial face of the piston ring and extending substantially parallel to the side wall with which it is in engagement.

  • Non-circular piston rings
    Patent number: 4957212
    Abstract: A piston ring whose contour deviates from the circular shape, and in particular an elliptical or oval piston ring, which, when seen in the circumferential direction, has regions that, in the installed state as well as in the operating mode, exert less radial contact pressure than the remaining surface regions in order to reduce wear of and leakage by the ring.
