ABSTRACT:
A flow rate limiting device (40) for a fuel dispensing nozzle (10) having an inlet (12) through which fuel is supplied to said nozzle (10) from a supply hose (14) and an outlet (20) from which fuel is discharged, as into a tank of a vehicle. The device (40) includes a flow restrictor (42) which is mounted in the fuel dispensing nozzle in its internal flow passage (16) the flow restricter (42) is automatically operated to reduce the flow rate, when the flow rate of fuel through said nozzle (10) reaches a preselected threshold rate such as the rate established by governmental regulations. After the flow rate of the fuel in the internal flow passage (16) is reduced below the preselected threshold rate, the flow restriction is attentuated such that the flow in the passage (16) can increase and approach the threshold rate.
