    摘要: The invention pertains to an automatic shut-off refueling nozzle (10) particularly suitable for use with military vehicles employing a nozzle having a liquid level sensor (20,22) operating a flow valve (12), the nozzle includes a lug plate (60) attachable to the inlet (74) of the tank receptacle being filled wherein once attached to the tank inlet (74) the presence of an operator is not required during refueling. A diverger (26) on the nozzle spout (14) improves flow characteristics within the tank inlet (74) to prevent immature release of the nozzle flow valve (12) and the nozzle prevents contamination during refueling and prevents spillage of volatile fuels even though unattended. An embodiment of the invention utilizes a secondary control valve (138) preventing fluid flow until the nozzle has been fully connected to the tank inlet.
