Abstract
Official abstract text for this publication.
An assembly for holding a fluid includes an auxiliary reservoir inside a main reservoir. The auxiliary reservoir includes an auxiliary reservoir shell with a fill passage at or near its bottom. The auxiliary reservoir shell also has a vent passage at or near its top. The fill passage and the vent passage fluidically connect the auxiliary reservoir to the main reservoir. A fluid inlet is located inside the main reservoir and outside of the auxiliary reservoir. A fluid outlet located inside the auxiliary reservoir between the fill passage and the vent passage.
First claim
Opening claim text (preview).
What is claimed is: 1. A method for circulating a lubricant in a gas turbine engine, the method comprising: pumping the lubricant from a first reservoir to a first engine component through a first supply passage with a first supply pump; scavenging the lubricant moved by the first supply pump from the first engine component to an inlet of the first reservoir; pumping the lubricant from a second reservoir disposed within the first reservoir to a second engine component through…
