Plastic filling nozzle for use at filling stations

Claim 1

An electrically conductive nozzle assembly for delivery of a liquid from a source to a liquid receiver having an inlet, said nozzle assembly comprising: (1) a rigid plastic nozzle including a nozzle inlet adapted for connection to a source of liquid, said source having electrical path means communicating with an electrical ground; a nozzle outlet; a nozzle housing coupling said nozzle inlet and said nozzle outlet; control means for controlling liquid flow from said nozzle inlet through said nozzle housing to said nozzle outlet; and a proper insertion safety valve for preventing discharge of liquid through said control valve unless the nozzle is properly inserted into the liquid receiving inlet; and (2) means for conducting an electrical charge comprising an annular conductor disposed on said nozzle and adapted to make electrical connection with the electrical path means of said liquid source; electrical conductive means disposed on said nozzle outlet to make contact with said liquid receiver inlet, said electrical conductive means being a lever pivoting on said nozzle and operatively connected to said safety valve for opening said safety valve when the nozzle outlet is introduced into the liquid receiver inlet; and electrical connective means for coupling said electrical conductive means with said annular conductor.
