  • Dripless means for a fuel dispensing nozzle
    Patent number: 7748419
    Abstract: A dripless means for a fuel dispensing nozzle begins with a nozzle for dispensing fuel into automobile tanks. Regulations limit drainage of the spout to within ten seconds, met by the present invention that prevents fuel drops from exiting the spout. First, the spout retains fuel drops behind a dam made of a series of fins upon the interior of the spout. Second, the present invention has a bushing with a weir that works in combination with the damming. Third, the nozzle has a vent tube within the spout where a plug constricts its diameter to limit the fuel drawn into the vent tube. With proper use, the present invention retains fuel drops in the spout to meet the regulations.
