Abstract: Modularized components assembled dispensing nozzle, including operating components in the category of a poppet valve assembly, an automatic shutoff device, a hand operating lever for providing a turn on or shutoff of the dispensing of fluid through the nozzle, and a connected spout that delivers fluid to the fill pipe and fuel tank for a vehicle or fluid accepting container. Each of the identified components having been redesigned for assembly in modularized form, such as a modular cartridge for the poppet valve, a modular cartridge for the automatic shutoff device, a modularized operating hand lever, and a spout and its gland and retaining nut that provide for high speed interconnection with the nozzle body, during assembly, or servicing. Each of these modularized components can be installed, during assembly of the manufactured nozzle, or can be replaced, out in the field, by a service person, as a modularized component or cartridge assembly.

Abstract: A carbon canister with a valve activated by the weight of nearly saturated or saturated carbon communicates with piping from an underground tank. The invention includes carbon within a casing inside a canister, a weight actuated valve, and piping in communication with the atmosphere. When an ORVR vehicle refuels, the pressure lowers in the tank that draws air into the canister. After refueling, the tank remains subject to conditions that generate hydrocarbon vapors. Those vapors then return to the canister and adhere to the surface of the carbon. The carbon, heavier with hydrocarbons, lowers the canister and closes the weight actuated valve. Closing the valve returns pressure control to an external pressure vacuum relief valve. The next refueling draws in atmospheric air to purge the hydrocarbons in the canister and thus lighten it. A secondary purge valve also removes hydrocarbons from the canister. Once the carbon lightens, the inlet valve opens and the vapors return to the canister for adsorption.

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.
