Abstract
A fueling nozzle having a rotatable locking ring adjacent its discharge end and adapted for mating with and being secured to a fuel receiving tank adapter at a common datum line has a receiving antenna associated with the nozzle and the fuel receiving tank has a transmitting antenna associated therewith. The fueling nozzle is activated by information transmitted as a continuous radio frequency signal from a continuously operating identity transmitter mounted on a vehicle desiring fueling. The identity transmitter is powered by the vehicle power source and requires no special activation by the user. The receiving antenna comprises a circumferential band completely encircling the nozzle and is insulated therefrom and secured thereabout. The receiving antenna is in such close proximity with the transmitting antenna as to interrupt transmission of the information and to cause cessation of a fueling operation upon withdrawal of the fueling nozzle from the fuel tank by more than a maximum functional distance.
