ABSTRACT:
A ring seal having a continuous circumferentially extending and radially facing outside diameter seal dam positioned adjacent the upstream, axially facing, high pressure side of the ring seal. The seal dam is aerodynamically connected to a downstream axially facing, low pressure side of the ring seal by axial vents. A plurality of radially extending upstream face vents on the high pressure side of the ring seal are aerodynamically connected to a corresponding axially facing upstream transverse sealing dam. A plurality of radially extending, downstream face vents on the low pressure side of the ring seal are aerodynamically connected to a corresponding axially facing, downstream transverse sealing dam. The upstream and downstream face vents serve to reduce an axial force exerted against the ring seal and the outside diameter vents which are aerodynamically coupled to the outside diameter seal dams serve to increase a radial force which pushes the ring seal against a stationary outer seat causing the ring seal to maintain a desired fixed position.
