Abstract: The present invention therefore aims at providing a nozzle that reduces the amount of residual fuel left on a spout after fueling by encouraging the residual fuel to drip into the container to be filled. A fuel dispensing nozzle is comprised of a nozzle body, a fuel regulating valve, and a spout for directing the fuel supply from the regulating valve to and in the container to be filled. After a fueling cycle, fuel clings to both the inside and outside spout surfaces and can be considered a falling film. Wherein existing nozzle spouts have discontinuous spout end faces that impede the flow of falling films into the container to be filled, the improved nozzle and endface according to the present invention encourage the falling films to create drops that fall into a container to be filled.

Abstract: The present invention is directed to fuel dispensing nozzles and more particularity to a spout of a fuel dispensing nozzle that reduces the amount of harmful emissions created during a fueling cycle. The spout of the nozzle has an inside surface that is in direct contact with a flow of fuel. After the flow of fuel is stopped, the residual amount of fuel adhered to the inside spout surface is encouraged to collect and drip from at least one fuel collection channel. The at least one fuel channel results in less fuel dripping on the ground and less residual fuel, both of which harmfully evaporate into the air.

Abstract: A fuel dispensing nozzle having a valve for controlling the flow of fuel to a spout attached to the nozzle. The nozzle spout includes three or more spaced apart protrusions that extend from an outer surface of the spout. If the outer spout surface is made from a non-electrically conductive material, the plurality of protrusions may be made from a electrically conductive material, and thus, provide electrical grounding to the nozzle. If the outer spout surface is made from a material having less than ideal wear properties, the plurality of protrusions may be used to provide wear protection to the outer surface.

Abstract: A low liquid retention fuel nozzle that is mainly comprised of a nozzle body and a spout attached to the nozzle body. A fuel supply travels down the nozzle body and through the spout and into a container. Typically, after the flow of fuel is stopped within a nozzle, fuel drips from the spout and resides on its surfaces. Nozzle spouts are typically made from aluminum which is easily wet-out by fuels which facilitates the creation of drips and residual fuel. The present invention is directed towards a spout with one or more surfaces that have a low surface energy. The low surface energy promotes drops to form. The resulting drops are likely to fall into the container to be filled prior to the user removing the spout from the container. The result is less contaminating fuel drops on the ground and less environmentally polluting fuel vapors reaching the atmosphere.
