ABSTRACT:
A multiple path fluid circuit comprising a fluid reservoir and a fluid pump having an inlet in fluid communication with the fluid reservoir. The fluid pump may have an outlet in fluid communication with an inlet of a fluid cooling circuit. The fluid cooling circuit may then have an outlet in fluid communication with the fluid reservoir. The outlet of the fluid pump may also be in fluid communication with an inlet of a lubrication circuit, which may be in fluid communication with a delivery system capable of supplying a fluid to a moving component or to a component in contact with the moving component. A gas turbine engine comprising a multiple path fluid circuit is also disclosed as well as a method of utilizing a multiple path fluid circuit.
