  • Patent number: 4090720
    Abstract: An expander spring for supporting an oil scraper ring in a groove of a piston is constituted by a sheet metal ring having an axis and forming an annular channel of generally U-shaped cross section. The channel has two side walls, forming, respectively, a radially inner and a radially outer, axially oriented side of the expander spring. The channel further has a base interconnecting the side walls and an open side opposite the base. A plurality of circumferentially distributed slots are provided in the side walls for increasing the resiliency of the expander spring in the circumferential direction, and a plurality of axially projecting support feet are carried by the free end of the radially inner side of the expander spring for supporting at least one oil scraper ring.

  • Patent number: 4084826
    Abstract: A shaft seal ring has a resilient sealing lip provided with a contact face oriented at an inclined angle with respect to the seal ring axis. The contact face includes a sealing edge for circumferentially engaging the surface of a shaft on which the shaft seal ring is mounted. The contact face has a plurality of circumferentially disposed ribs oriented at alternatingly opposite inclination with respect to the sealing edge. Any adjoining, oppositely inclined two ribs meeting in a point of intersection on the sealing edge form first rib pairs. A second rib pair is provided in the area bounded by the one and the other rib of each first rib pair; the one and the other rib forming each second rib pair terminates on, and is oppositely inclined with respect to, the one and the other rib of the associated first rib pair.
