Abstract
A lubrication system for use with a gas turbine engine includes a first reservoir for containing a lubricant. The first reservoir includes a first discharge passage through which the lubricant is flowable in a first direction. A second reservoir contains the lubricant. The second reservoir includes a second discharge passage through which the lubricant is flowable in a second direction. The first direction is generally opposite to the second direction. A first pump pumps the lubricant from the first reservoir. A second pump pumps the lubricant from the second reservoir. A manifold distributes the lubricant to a component. The lubricant from the first pump and the second pump flows into the manifold and exits the manifold through a manifold discharge.

A lubrication system for use with a gas turbine engine comprising:
- a first reservoir for containing a lubricant, wherein the first reservoir includes a first discharge passage through which the lubricant is flowable in a first direction;
- a second reservoir for containing the lubricant, wherein the second reservoir includes a second discharge passage through which the lubricant is flowable in a second direction, wherein the first direction is generally opposite to the second direction;
- a first pump that pumps the lubricant from the first reservoir;
- a second pump that pumps the lubricant from the second reservoir;
- and
- a manifold to distribute a constant and uninterrupted supply of the lubricant to a bearing, wherein the lubricant from the first pump and the second pump flows into the manifold to combine into a common flow, and the common flow exits the manifold through a common manifold discharge.
