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.
Claims6
The combination with an airplane having a wing with multiple turbo-jet engines and each having an associated main oil tank mounted thereon, of a supplemental oil system to replenish oil in each main oil tank, said system comprising:
- a reserve tank of oil located internally of said airplane;
- a pipeline connecting said reserve tank to each said main tank;
- a container having a measured capacity less than that of said reserve tank located in said pipeline;
- valving in said pipeline operable to permit the flow of oil from said reserve tank to said container and a distribution valve to control the flow of oil from said container to a selected one of said main tanks;
- and
- a force pump to assure the flow of oil from said reserve tank to said container and to each said main tank when free to do so upon the operation of said valving.
