  • Metal face seal assembly and machine using same
    Patent number: 7887061
    Abstract: A metal face seal assembly for sealing between machine components includes a first subassembly and a second subassembly rotatable relative to the first subassembly. Compressible seals positioned between inner and outer seal members of the subassemblies provide a non-axial sealing load, whereas at least one metallic biaser provides an axial face load to bias inner seal members of each subassembly together at a rotatable interface.
    Type: Grant
    Filed: September 14, 2007
    Date of Patent: February 15, 2011
    Assignee: Caterpillar Inc
