    Abstract: A seal assembly for a bearing compartment includes a coupler with a lip, seal plate, nut, and air seal land. The seal plate is disposed on and around the coupler and is in contact with the lip. The nut is disposed within the bearing compartment and adjoining the seal plate. The nut includes first, second, and third major portions and first and second intermediate portions. Each of the first, second, and third major portions is in the shape of an annular band. The second major portion is disposed axially between the first and third major portions. The third major portion includes a knife edge seal extending radially outward. The first and second intermediate portions include frustums and extend between the first and second major portions and second and third major portions, respectively. The air seal land is sealingly engaged with the third major portion of the nut.

    IPC: F16H57/04

    Abstract: An assembly is provided for a gas turbine engine. This assemble includes a stationary structure configured with a first side, a second side and a bore that extends through the stationary structure between the first side and the second side. The assembly also includes a fluid transfer tube extending within the bore and forming a plenum between a sidewall of the fluid transfer tube and the stationary structure. The fluid transfer tube is configured with a first end at the first side, a second end at the second side, a flowpath and an aperture. The flowpath is at least partially formed by the sidewall and extends through the fluid transfer tube between the first end and the second end. The aperture fluidly couples the flowpath with the plenum.
