A fluid dispensing nozzle including a nozzle body having a fluid path and a suction path therein. The nozzle has a valve positioned in the fluid path and configured to selectively prevent or allow a flow of fluid through the fluid path, and a manually operable actuator operatively connectable to the valve. The nozzle also includes a suction generator configured to apply a suction force in the suction path at a suction location. The suction path includes an expansion chamber located upstream of the suction location with respect to a direction of flow in the suction path. A bottom surface of the expansion chamber and a bottom surface of a portion of the suction path positioned immediately upstream of the expansion chamber are generally aligned.

A fuel filler device that includes a flow conduction device arranged in a filler line and configured such that during a filling, an outlet pipe of a pump nozzle is guided and supported therein, and an attachment connected to the flow conduction device. The attachment includes a first attachment end, a second attachment end, and a constriction extending between the first attachment end and the second attachment end such that the attachment tapers from the first attachment end to the second attachment end via the constriction. At least one first gap is formed between the first attachment end and the flow conduction device so that during a filling sequence, fuel vapour introduced into the fuel filler device may flow through the at least one first gap into the filler line in a direction of a fuel tank connected to the filler line.

Systems are provided for refueling a fuel tank of a motor vehicle via a funnel including an insert. In one example, a system may include a funnel including an insert coupled to an inner circumference of the funnel, the insert including a plurality of projections positioned on an inner perimeter of the insert. The plurality of projections may include a first projection spanning a first axial length, a second projection spanning a second axial length, and a third projection spanning a third axial length.

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 at least part of the suction path when fluid to be dispensed flows through the fluid path. The nozzle further includes a shut-off device including a suction chamber fluidly coupled to the suction path and configured such that when the suction path is blocked during fluid dispensing the shut-off device moves to a closed configuration to prevent the nozzle from dispensing fluid through the fluid path. The suction path includes a terminal portion in fluid communication with the suction chamber, and the terminal portion has a cross sectional area of at least about 0.015 square inches.

A device for fueling motor vehicles with a fluid used as a fuel and composed of liquefied gas, in particular liquefied natural gas, includes: at least one storage container; a cooling device; at least one conveying device for feeding the fluid from the at least one storage container to at least one fueling device for motor vehicles; and at least one line for supplying the fluid to the fueling device. The at least one line includes a media-conveying central pipeline as a medium pipe and at least one additional media-conveying pipeline that is arranged concentrically with respect to the central pipeline and defines an annular space together with the media-conveying central pipeline. The media-conveying central pipeline and the at least one annular space supply and return the fluid or a gas flow. The at least one additional media-conveying pipeline is surrounded by a jacket pipe.
