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 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.
Abstract translation: 用于风扇驱动齿轮系统的润滑系统包括润滑剂供应和用于从润滑剂供应内抽出润滑剂的收集管道。 收集管道包括第一开口和用于抽出润滑剂并向泵供应润滑剂的第二开口。 在正常操作期间，润滑剂可以通过第一和第二开口被拉出。 在负G运行条件期间，第二开口处的配件阻塞第二开口，以防止空气被吸入润滑剂系统并传递到泵。
