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.
