An automatic truck tank fill system includes a conduit in fluid communication with a fluid supply source. An electrically controlled valve is in fluid communication with the conduit. A fill spout is in fluid communication with the conduit, the fill spout including an outer chamber. A controller is in electrical communication with the valve. A first signal opens the valve from a closed position permitting fluid flow through the conduit, and a second signal causes the valve to close, preventing fluid to flow through the conduit. A tubing is in fluid communication with the fill spout. A pressure transducer is in fluid communication with the tubing, and the controller is in electrical communication with the pressure transducer. When a pressure in the tube reaches or exceeds an activation pressure (P1), the controller sends a signal to close the valve in the conduit.

Disclosed is a system and method for delivering fuel to a plurality of vehicles. The system comprises a fuel source, a pump operable to draw fuel from the fuel source and a distribution manifold having a plurality of outlets. The system further comprises a plurality of fuel lines extending from the distribution manifold and a plurality of valve assemblies, each located in a tank of one of the plurality of vehicles each of the valve assembly being operable to independently shut off flow of fuel therethrough when the tank is filled to a predetermined level. The method comprises pumping the fuel supply from the fuel source to the distribution manifold, connecting a plurality of fuel lines to the distribution manifold and a valve assembly in each of a plurality of trucks in connection with one of the fuel lines.

An attitude sensing arrangement for triggering a shutoff mechanism on a fuel dispensing nozzle comprising a rolling element placed inside a non-cylindrical chamber that is sealed with a plug such that the rolling element may move freely inside the chamber. A vacuum sensing path passes from a sensing port in the nozzle spout, through a vacuum sensing tube, into the non-cylindrical chamber, and into a venturi-generated vacuum chamber. The attitude sensing arrangement is configured such that the rolling element blocks a shutoff port in the non-cylindrical chamber when the nozzle is raised past a certain shutoff angle. When the vacuum sensing path is blocked by the rolling element in this manner, the shutoff mechanism closes the main fuel valve.

A refuelling coupling having a shut off valve for a refuelling system has an annular member equipped with a connector for a pressure refuelling nozzle. A main sleeve extends down from the annular member within the skirt. The sleeve has an annular valve seat and a circular cylindrical distal end section. The seat has a conical face facing obliquely inwards and downwards. Below the valve seat, a plurality of peripherally arranged openings are provided in the end section. An end cap is screwed on across the very end of the lower portion, closing it with ports in the end cap. It also has an inner sleeve extending back up centrally to the level of the valve seat. The end cap is open inwards of the inner sleeve.

A fuel dispensing nozzle, incorporating a uniquely shaped gasket for the poppet valve, generally of truncated shape, enhances the flow of fuel through the nozzle when actuated. A handle lever for the nozzle, which is designed having an elongated and enlarged end, includes elongated slots, that are pivotally pinned through both the latch plate, and the handle link, in order to reduce the space between the interconnection between the front of the latch plate to the bottom of the automatic shutoff stem, such that by lessening the distance between these components, thereby reducing the fulcrum point for the calculation of the force necessary to open the nozzle by raising its handle lever, and reduces the force necessary to achieve nozzle opening and actuation, to less than 5 lbs pressure during usage and application.
