  • Patent number: 4947905
    Abstract: An automatic shut-off fuel dispensing nozzle (10) with a flow rate limiting mechanism (90). The nozzle (10) includes a valve (24) which controls the flow of fuel through a passage (16) leading from the nozzle inlet (12) to the nozzle outlet (20) which is normally connected to a spout. This valve (24) is responsive to a manually operable lever and to a vacuum operated release mechanism (26) 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.
