VALVING SYSTEM FOR SUPPLYING FUEL TO TANKS AND TRANSFERRING FUEL BETWEEN TANKS

A flow control system to admit fuel to an aircraft fuel tank and to provide for fuel transfer between that tank and another tank. The system includes a pilot valve which is sensitive to fuel level at an upper elevation of the tank, and a flow valve disposed at a lower elevation of the tank. A fuel c...

Beschreibung
Zusammenfassung:	A flow control system to admit fuel to an aircraft fuel tank and to provide for fuel transfer between that tank and another tank. The system includes a pilot valve which is sensitive to fuel level at an upper elevation of the tank, and a flow valve disposed at a lower elevation of the tank. A fuel conduit connects the flow valve to a source of supply and to other tanks to which fuel is to be transferred, and a pilot line interconnects the pilot valve and the flow valve. The flow valve is a differential pressure type valve, and a flow signal for selecting its flow condition is supplied by the pilot valve. Means is provided to change the condition of the pilot valve for shutoff and for checkout purposes. The flow valve may also include shutoff means responsive to an empty tank and to negative g-forces.
