AIRCRAFT FUEL TRANSFER PUMP WITH AUXILIARY FUEL LINE SCAVENGE PUMP |
摘要 |
<p>An improved fuel transfer pump is provided for relatively high flow transfer of fuel from one aircraft to another during an inflight refueling procedure, wherein the fuel transfer pump includes a jet-type scavenge pump for evacuating residual fuel from a fuel line or manifold. The scavenge pump comprises a venturi element connected along a recirculation conduit through which a small fuel flow is diverted from the high pressure discharge side of the fuel transfer pump for return to the fuel tank. The recirculation fuel flow induces a vacuum in a suction throat of the venturi element, and this vacuum is coupled by a suction line to evacuate residual fuel from the fuel line or manifold to the fuel tank. A flow baffle is mounted along the recirculation conduit downstream from the venturi element to ensure flooding and priming of the scavenge pump.</p> |
