Abstract: An ORVR valve assembly operative of relatively few movable components includes a valve body, having conduits to provide for routine passage of vapors therethrough through operations of a vacuum assist system. This is when a non-ORVR vehicle is being replenished with fuel. But, when a vehicle equipped with ORVR vapor recovery is being fueled, vacuum is generated above a piston supported diaphragm, attracts the diaphragm upwardly, plugs off the vapor passage conduits, and allows the ORVR system of the automobile to exclusively treat the generated vapors at the location of the vehicle and its fuel tank. Simultaneously, air is vented into the valve body, below its diaphragm, and into the vapor return line of the vacuum assist system, to prevent it from being subject to excessive vacuuming.

Abstract: A breakaway coupling including a pair of sleeves, one sleeve fitting within the other, each sleeve provided with a connector body, and a hose connector secured with one of the connector bodies. The first sleeve holds a metal annulus, while the second sleeve secures a ring separator, counterbored, to secure a series of round magnets therein, so that when the sleeves and their connector bodies are brought together, they are secured by the magnets into connection. When excessive force is encountered, the breakaway will separate, to prevent further discharge of fuel from the nozzle. A swivel connector secures with one of the connector bodies.

Abstract: A breakaway coupling including a pair of sleeves, one sleeve fitting within the other, each sleeve having a hose connector secured therethrough, the first sleeve holding a metal annulus, the second sleeve securing a continuous magnetic annulus, so when the sleeves are brought together the magnetic annulus secures onto the metal annulus to hold the coupler in its connected position. The continuous metallic annulus includes a metal base, a spacer that holds a series of standard round magnets equally spaced around the approximate perimeter of the spacer and its base.

Abstract: A breakaway coupling including a pair of sleeves, one sleeve fitting within the other, each sleeve provided with a connector body, and a hose connector secured partially with one of the connector bodies. The first sleeve holds a metal annulus, while the second sleeve secures a ring separator, generally counterbored, to secure a series of round magnets, so that when the sleeves and their connector bodies are brought together, they are secured by the magnets into connection, but that when an excessive force is encountered, the breakaway will separate, and prevent further discharge of fuel from the nozzle or its fuel line hose. Connecting with one of the connector bodies is a swivel connector, which can furnish a degree of pivot to the swivel, and its connected nozzle, or the hose, during usage. The swivel connector includes male and female portions, which provide for a degree of pivot, while the male portion further includes a swivel nut, which adds further turnability to the entire unit, during installation.

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.

Abstract: An underground fuel tank releases vapors depending upon air pressure. A vapor pressure management system has a canister for a vapor recovery system that connects with piping from an underground tank and has carbon therein along with appurtenant pipes and valves. When an ORVR vehicle refuels, the pressure lowers in an underground tank that draws air through the valves into the canister. After refueling an ORVR vehicle, environmental conditions generate hydrocarbon vapors. Barometric pressure drops and evaporated fuel during long refueling lulls produce hydrocarbon vapors at an increased pressure. Those hydrocarbon rich vapors then return to the canister of the system where the carbon binds the hydrocarbons while releasing air to the atmosphere. The refueling of the next ORVR vehicle draws in atmospheric air to purge the hydrocarbons retained in the canister of the system.
