Abstract

See full text

A seal assembly for a bearing assembly in a gas turbine engine includes a first annular runner disposed around a shaft rotatable about an axis defining an axial direction. The first annular runner is rotatable with the shaft about the axis. A seal element is spaced apart from the first annular runner and cooperating therewith to provide a gap seal. An annular lip axially extends from the gap seal to an open end. The lip is disposed at least partially around the seal runner. A second annular runner is disposed coaxially with and spaced radially apart from the lip. The second annular runner extends axially opposite to the lip so as to provide a tortuous path leading to the open end of the lip. A restrictor extends between the lip and the second annular runner to impede the passage oil through the tortuous path to the open end of the lip.
