Abstract
A gas turbine engine includes a bearing compartment with a bottom disposed opposite a top. An outlet is formed in the bottom of the bearing compartment. A seal is positioned between the bottom of the bearing compartment and the top of the bearing compartment. A scavenge line is connected to the outlet. The scavenge line forms a fluid trap that extends in a first direction from the outlet and the bottom of the bearing compartment and then extends in a second direction to a position disposed vertically between the bottom of the bearing compartment and the seal.
