发明名称 Gas turbine engine bearing compartment seal
摘要 A seal for coaxial inner and outer spools rotatable about an axis is provided which includes a flange having a catch surface. The flange is attached to the outer spool, and is disposed between the inner and outer spools such that the catch surface is in close proximity to the inner spool. The catch surface, which includes a seal end and a discharge end, is canted from the axis between the seal end and the discharge end. Liquid disposed between the inner spool and the catch surface is forced against the catch surface by centrifugal force when the spools rotate at a sufficient speed. The liquid is subsequently driven axially along the canted catch surface in the from the seal end to the discharge end, toward the bearing compartment.
