Abstract: A proportioner apparatus is capable of proportioning and admixing at least two liquids at relatively low pressures. The proportioner apparatus has a pressurizable reservoir for each liquid and a mix reservoir. A fluid communication conduit provides fluid communication between the interior of the mix reservoir and the interior of the liquid reservoirs. The liquid reservoirs are pressurized with a pressurizing gas to cause flow from the liquid reservoirs into the mix reservoir. A discharge conduit of the mix reservoir discharges admixture therefrom. When flow ceases in the discharge conduit the flow into the mix reservoir is also stopped as by shutoff valves in the fluid communication conduit. The proportioner apparatus can also include a pump operably associated with the discharge conduit to enhance admixture flow to a pressurizable tank that holds the admixture for further downstream processing. The pressure downstream of the pump is usually higher than the pressure upstream of the pump.

A pair of wing tanks integrated to the high wing of the Canard aircraft, to the rear of the strake tanks, feed along with individual horizontal fuel lines from the strake tanks to a central fuel collector tank interposed between the main high wing sections with low pressure drop flapper check valves at the ends of the individual horizontal lines internally of the collector tank for preventing fuel from leaving the collector tank. The primary gravity feed system defined thereby isolates each tank from the other, thereby preventing large fuel excursions during extreme flight maneuvers.

Abstract: An in-tank, fuel pump assembly for fuel-injected engines is provided which includes a reservoir having a supply port for supplying fuel to the engine and a return port for receiving fuel returning from the engine. Within the reservoir are (1) an electrically-operated, high pressure pump, (2) a jet pump located at the bottom of the reservoir for entraining fuel into the reservoir, (3) a valve associated with the return port, and (4) a valve associated with the supply port. The output of the high pressure pump is routed to the jet pump and to the two valves whereby when the high pressure pump is not operating, both valves are closed, and when the high pressure pump is operating, both valves are open and the jet pump entrains fuel into the reservoir. The jet pump is sized to entrain more fuel into the reservoir than leaves the reservoir through the supply port thus producing a net flow of fuel from the bottom to the top of the reservoir.
