Abstract: A bearing assembly includes a bearing, an outer race located radially outward of the bearing and supporting the bearing, a bearing housing located radially outward of the outer race and supporting the bearing and the outer race, and a bearing lubricant drain including a multi-directional passage formed in one or both of the outer race or the bearing housing, the lubricant drain arranged to cause a lubricant to flow from a first location to a second location. The second location is radially outward and axially offset from the first location. A gas turbine engine includes a shaft configured to rotate about a centerline axis of the gas turbine engine and the bearing assembly configured to facilitate the rotation of the shaft.

Abstract: An apparatus for filling an oil tank may include one or more valves that may be arranged and/or sized in such a way as to assist in venting the oil tank during a fill operation and assure that the tank may be filled within a reasonable time.

Abstract: A dry rolling element bearing assembly for rotatably mounting a flight vehicle engine shaft to a housing. Rolling elements (such as ball bearings) are positioned between inner and outer races. Stop devices axial position the inner and outer races. A mounting device positions the inner race radially outward from the shaft so as to create a first annular air space between them. The mount has a flexible portion and has a support ring portion which contacts the outer surface of the inner race with a radial interference fit. A similar mounting device positions the outer race radially inward from the housing. Air directing devices direct cooling air impingingly against bearing surfaces.
