  • Fuel system having a valve upstream of a jet pump
    Patent number: 11434931
    Abstract: A fuel system includes a fuel reservoir configured to be located within the fuel tank such that the fuel reservoir defines a fuel reservoir volume which is a subset of a fuel tank volume; a fuel pump configured to pump fuel from within the fuel reservoir volume to the fuel consuming device through a fuel supply line; a jet pump configured to 1) receive excess fuel, through a fuel return line, which had been supplied to the fuel consuming device through the fuel supply line and 2) aspirate fuel into the fuel reservoir volume from the fuel tank volume; and a valve which allows fuel flow in both directions between the fuel return line and the jet pump when a differential pressure across the valve is greater than or equal to a predetermined threshold.
