Abstract: A seal for reducing leakage about a rotating shaft having an axis includes a rotating component configured to be positioned radially outward from and surround the rotating shaft, and including a rotating cylinder defining an annular oil chamber for receiving oil. The seal also includes a static component including a sealing plate configured to extend into the annular oil chamber such that the oil fills a gap between the sealing plate and the rotating cylinder to reduce air leakage between the rotating component and the static component in response to rotation of the rotating component.
