Abstract:
1. A metal face seal assembly for sealing between components in a machine comprising: a first subassembly including an inner seal member having a sealing face and an outer seal member positioned about and spaced radially outer from said inner seal member; and a second subassembly rotatable relative to said first subassembly and also including an inner seal member having a sealing face and an outer seal member positioned about and spaced radially outer from the respective inner seal member; said metal face seal assembly having a longitudinal axis, and said subassemblies each having a non-metallic compressible seal directly contacting the corresponding inner and outer seal members, and generating a sealing load in a non-axial direction to fluidly seal between the corresponding inner and outer seal members; and said subassemblies each metal further including a metallic biaser separate from said compressible seals and directly contacting the corresponding inner and outer seal members, each of the metallic biasers being compressed between the corresponding inner and outer seal members, and generating a face load in an axial direction to bias the sealing faces of said inner seal members together at a rotatable interface.
