  • Transfer jet pump prime reservoir with integrated anti-siphon valve feature
    Patent number: 7216633
    Abstract: A movable fuel valve lies within a housing at an end of a housing fuel passage. A fuel tube has a nozzle end inserted within a first end of the housing fuel passage while the movable valve element is situated at a second end of the housing fuel passage and controls fuel flow from the second end of the housing fuel passage. The nozzle end remains surrounded in fuel when the valve element is closed and sealed against the second end of the housing fuel passage. When the fuel pressure within the housing fuel passage is greater than a fuel pressure on the other side of the valve, the fuel flows from the housing fuel passage, through the part of the housing surrounding the valve, and into the reservoir. The movable valve element prevents fuel from flowing from the main-side of a fuel tank to the sub side of the tank.
