Abstract:
A carbon seal for the bearing compartment for a gas turbine engine has radially extending passages in the rotating seal plate so arranged as to pump oil by centrifugal force from the space between the seal plate and the shaft into the bearing compartment surrounding the seal. With this seal plate no detrimental oil accumulation is permitted in this space.
