ABSTRACT:
Leakage of compressed air into the lubrication system of a gas turbine engine is prevented by a seal construction including a housing (44), a hollow shaft (40) extending through the housing (44) and adapted to receive lubricant on its interior (58), and a bearing (48) journalling the shaft for rotation within the housing. The bearing (48) includes an inner race (60) provided with a sealing surface (72). A seal holder (74) is carried by the housing (44) and receives an annular seal (82). Passages (94), (96) through the hollow shaft (40) align with passages (98), (102) in the inner race (60) to one side of the sealing surface (72) to direct lubricant from the interior (58) of the hollow shaft (40) to the bearing (48).
