Abstract
An oil replenishment system provides a remote reserve oil tank and the plumbing necessary to fill the main oil tank or tanks of engines, especially aircraft engines during flight. This system includes apparatus to determine the quantity of oil pumped to any one engine so that a quantity gauge is not required on the engine. A selector valve located on the reserve tank which may be remotely controlled directs replenishment oil to the selected engine tank. The system is designed to be powered from the existing on board hydraulic power system.
