    Abstract: A pump assembly includes a first stage including a first inlet in communication with a first cavity, and a first pumping means disposed within the first cavity. A second stage includes a second inlet in communication with a second cavity, an outlet in communication with both the first and the second cavity, and a second pumping means disposed within the second cavity. A transfer plate is disposed between the first stage and the second stage. The transfer plate includes a transfer window. The entire transfer window is disposed horizontally above the first pumping means and the second pumping means.

    Abstract: A bi-directional auxiliary lubrication system which allows lubricant to be supplied to moving engine components after a loss of lubricant pressure from a main lubricant tank is disclosed. In a gas turbine engine, the lubrication system may siphon compressed air from a compressor to draw lubricant from a reserve lubricant tank and deliver that lubricant to the engine components. The same conduits used by the lubrication during normal operations are utilized in an opposite direction to provide the flow of lubricant from the reserve lubricant tank during such auxiliary or low-lubricant-pressure operations.

    Abstract: A lubrication system for a fan drive gear system includes a lubricant supply and a collection conduit for drawing lubricant from within the lubricant supply. The collection conduit includes a first opening and a second opening for withdrawing lubricant and supplying lubricant to a pump. During normal operation lubricant may be drawn through both first and second openings. During negative G operating conditions a fitting at the second opening blocks the second opening to prevent air from being drawn into the lubricant system and communicated to the pump.
