Abstract
An improved fuel dispenser actuator includes a flap in a nozzle support such that the nozzle engages the flap when the nozzle is put into the dispenser housing and not in use. The resulting movement of the flap moves a magnet on the flap out of proximity to a reed switch, thereby opening a circuit and disabling the dispensing of fuel.
Claims15
A fuel dispenser of the type provided with a hose connecting a dispenser housing and a nozzle comprising:
- a. a metering apparatus for metering fuel through the hose,
- b. a power supply for supplying power to the metering apparatus,
- c. a nozzle supporting said housing for supporting the nozzle when not in use, said nozzle support provided with a flap positioned to have a first orientation when said nozzle is removed from said nozzle support and a second orientation when said nozzle is supported by said nozzle support because of dislodgement of said flap from said first orientation to said second orientation by said nozzle's placement in said nozzle support,
- d. a magnetically actuable switch on said nozzle support operatively associated with said power supply and said metering apparatus, and
- e. a magnet mounted on said flap to cause said switch to have a first state when said flap is in said first orientation and to cause said switch to have a second state when said flap is in said second orientation, whereby when said switch is in said first state, said metering apparatus is operatively associated with said power supply to permit the dispensing of fuel through said hose and when said switch is in said second state, said power supply is isolated from said metering apparatus to prevent the dispensing of fuel through said hose.
