Methods and systems are provided for refueling a vehicle configured with an onboard refueling vapor recovery (ORVR) system, such that a loading of a fuel vapor canister configured to capture and store fuel vapors, is reduced. In one example, during the refueling, a rate at which fuel vapors are routed to the fuel vapor canister is adjusted responsive to an indication that the vehicle is refueling at a gas station equipped with offboard fuel vapor recovery infrastructure. In this way, loading of the fuel vapor canister may be reduced which may prevent undesired bleedthrough emissions resulting from a canister loaded with fuel vapors, particularly in examples where the vehicle is a hybrid vehicle and where engine runtime is limited, thus limiting potential opportunities for purging of the fuel vapor canister.

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 invention solves some of the problems of the prior art by providing a method, system and apparatus for readily refilling the reservoir of a smoking-substitute device with liquid from a dispenser. The method, system and apparatus of the present invention prevents liquid from being dispensed until the dispenser is securely and sealably engaged to the smoking-substitute device, provides independent liquid and gas pathways between the dispenser and reservoir, and substantially alleviates the problems of spillage and/or leakage when dispensing liquid from the dispenser into the reservoir of the smoking-substitute device.

A fluid dispensing nozzle including a nozzle body having a fluid path and a suction path therein. The nozzle includes a suction generator configured to generate a suction force in the suction path when fluid to be dispensed flows through the fluid path. The nozzle further includes a shut-off device having a suction chamber fluidly coupled to the suction path. The shut-off device is configured such that when the suction path is blocked during fluid dispensing the shut-off device prevents the nozzle from dispensing fluid through the fluid path. The suction chamber includes a lip extending around a perimeter thereof. An opening is formed in or extends through the lip, the opening providing fluid communication between the suction chamber and the suction path to enable liquid to flow from the suction chamber to the suction path.

The present disclosure relates to a dispensing gun with increased safety. The dispensing gun comprises an expansion chamber into which liquid trapped inside the dispensing gun can escape in case of expansion of said liquid, thereby avoiding an increase of pressure inside the dispensing gun resulting from such an expansion which could damage internal components, such as the outlet valve arrangement.

A nozzle for dispensing fluid including a nozzle body having a spout and fluid path through which fluid to be dispensed is flowable. The nozzle includes an actuator configured to detect when the spout is sufficiently inserted into a fluid receptacle, and a shut-off device configured to selectively terminate or prevent fluid dispensing operations through the fluid path. The nozzle further includes an interlock operatively coupling the actuator to the shut-off device. The interlock includes a slider that is operatively coupled to the actuator and a pivotable arm that is operatively coupled to the shut-off device, and the slider is slidable along the arm.
