摘要： A lubrication system (70) for a gas turbine engine (20) may include a pump (86) for moving a lubricant through a conduit from a lubricant tank (82) to an engine component (80). Further, a scheduling valve (94) positioned in the conduit (90) between the lubricant tank (82) and the engine component (80) may vary a flow of the lubricant (74) to the engine component (78) based on a condition.
