A channel forming member is attached to a filler neck on a nozzle insertion side where a fueling nozzle is to be inserted. The channel forming member includes a barrier section that forms an insertion flow path section for the fueling nozzle in the fuel flow path on the nozzle insertion side, while forming an annular channel surrounding the insertion flow path section so as to separate the channel from the insertion flow path section. The channel forming member further includes the following provided to the barrier section: an atmosphere communication hole for making the channel communicate with the atmosphere; a flow path communication hole for making the channel communicate with an insertion end flow path section downstream from the insertion flow path section; and a valve mechanism that prevents passage of the atmosphere through the channel in a fueling period. This contributes to reduction in introduction of the atmosphere into the fuel flow path through the channel in a fueling period.

A custom blending hose for manifold mixing of various fuels for a fuel dispensing system, including a pair of fuel dispensing hoses, generally concentrically or coaxially arranged, for passing at least a pair of fuels into a manifold assembly, for blending and intermixing of said fuels, for further delivery through a dispensing hose assembly, to a nozzle, for refueling of a vehicle. The manifold includes a housing, incorporating internally a series of apertures, through which the fuels are passed, and blended, for delivery as a uniform fuel to a vehicle during dispensing. A vapor return line may locate through the manifold.

The present disclosure is directed to various embodiments of threaded container valves and gravity nozzles. The gravity nozzle includes a threaded container valve and a delivery tube. The threaded container valve includes a valve section having a first inlet and a second inlet, and an engagement section coupled to the valve section. The delivery tube includes a fluid tube and a vapor tube. The fluid tube has a first end, configured to engage with the first inlet of the valve section. The vapor tube has a first end, configured to engage with the second inlet of the valve section. The fluid tube and the vapor tube each have a second end, configured to engage with a delivery inlet.

A nozzle adapter assembly is provided for adapting use of nozzles on liquid dispensing pumps with test and measurement equipment such as liquid provers, test measures and liquid proving systems. The adapter can be used with automatic shut-off nozzles through which the liquid may normally be dispensed.

A liquid loading assembly for filling a ship-hold or tank with a volatile liquid, includes an oil supply conduit, fluidly connected to the tank, the outlet end of said conduit extending vertically within a dropline. The dropline extends from a lower dropline end positioned below the outlet end of the oil supply conduit to an upper dropline end positioned above the outlet end of the oil supply conduit, the lower dropline end being at least partially closed by a valve. The valve is arranged to open gradually up to a maximum aperture in response to one of i) increased pressure on the valve and ii) a level of liquid above the valve.

Disclosed is a method and apparatus for the dispensing of liquids (e.g., fuel) where the apparatus and method include an improved nozzle that reduces residual liquid retained in the nozzle when dispensing is stopped.

Environmental friendly automotive fluid dispensing systems and are provided. One disclosed system provides for the controlled dispensing of an automotive fluid selected from multiple automotive fluids. A quantity of fluid to be dispensed can be designated and the system can dispense the designated quantity of the selected fluid. A pump assembly is used to transfer automotive fluid from a selected container to a dispensing gun in a controlled fashion. The product dispensing gun can include a check valve for preventing fluid from exiting the dispensing gun when no fluid is being transferred to the dispensing gun by the pump assembly.

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. Thus, vapor recovery or treatment can be achieved through the use of the ORVR valve assembly of this invention, regardless whether the automobile being refueled is an ORVR equipped vehicle, or one that is not equipped with vapor recovery.

Fuel hoses are provided herein to deliver a blend of fuels. For example, a fuel hose is provided that includes an upper hose portion with a first channel for delivering a first fuel and a second channel for delivering a second fuel. A lower hose portion with a third channel extending therethrough couples to a nozzle. The lower hose can couple to the upper hose portion at a joint that receives the first and second fuels. The first and second fuels can mix at the joint to form a blended fuel that is delivered through the lower hose portion to the nozzle.

A fuel tank system, comprising: a fuel tank configured to store a liquid fuel and a pressurized gaseous fuel capable of partially dissolving in the liquid fuel; a refueling conduit coupled to the fuel tank via a tank access valve; a first high pressure refueling port coupled to the refueling conduit; a low pressure refueling port coupled to the refueling conduit via a check valve. In this way, pressurized gaseous fuel or a pre-pressurized mix of fuels may be added to the fuel tank without active control any time the fuel pressure in the fuel tank is below a maximum allowable pressure, and liquid fuel may be added to the fuel tank with active control whenever the fuel pressure and liquid fuel level in the fuel tank are below threshold levels.
