A system for automatically transferring the fuel from one or more engine fuel manifolds directly to the engine fuel tank(s) during engine shutdown using an ejector pump has been presented. A checkvalve, which may be integrated with the ejector pump, is also used. A metering valve initiates fuel flow shutoff and is used in the draining of the fuel manifolds, thereby eliminating the need for an additional solenoid dedicated mainly to the shutoff function. The shutoff and pressurizing valve provides flow division between manifolds and manifold drain for sys...


What is claimed is: 1. A system for transferring fuel from at least one engine fuel manifold of a gas turbine engine to a fuel tank comprising: a fuel metering and shutoff valve configured to provide high pressure fuel to the at least one engine fuel manifold; a bypass valve in fluid communication with the fuel metering and shutoff valve; an ejector having an inlet port for receiving fuel from the bypass valve during engine operation, an outlet port in fluid communication with one of the fuel tank and a fuel tank ejector, and a suction port, the ejector...
