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 systems having multiple
manifolds. The bypass valve is used to turn the motive flow and/or manifold drain
functions on and off as a function of engine speed at start and shutdown.
