Abstract
An automatic shut-off duel dispensing nozzle with a flow rate limiting mechanism. The nozzle includes a valve which controls the flow of fuel through a passage leading from the nozzle inlet to the nozzle outlet which is normally connected to a spout. This valve is responsive to a manually operable lever and to a vacuum operated release mechanism which automatically shuts the flow of fuel through the nozzle off when the level of fuel in a tank reaches a preselected level or when the flow of fuel through the nozzle reaches a preselected threshold rate of flow.
