Patent 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.
