  • Patent number: 7287542
    Abstract: A vapor vent/tipping valve has a diaphragm with a bleed therethrough responsive to the differential pressure of bleed flow to control vapor venting to the canister and vapor recirculation to the filler tube. A dip tube causes rising fuel in the tank to close the dip tube and prevent vapor flow to the diaphragm bleed thereby starving the recirculation line and allowing nozzle discharge to create a vacuum in the filler and effect nozzle shutoff. Alternatively, float operated shutoff valves may be employed in the dip tube and vapor vent chamber inlet, the shutoff valves may include inertial members for closing the float valves to afford tipping/rollover protection.
