Abstract
A fuel dispensing nozzle has a vent tube extending through a spout of the nozzle and automatic shut off device in communication with, and responsive to, the passage of air through the vent tube. The vent tube terminates in an air port at the tip of the spout. A tip, forming a valve, is placed at the end of the vent tube. The valve has a magnetic responsive valve member and a seat formed at the junction of tip and the vent tube. The vacuum created by the nozzle seats the magnetic valve member against the seat to close the tube to activate the automatic shut off device. A vehicle which can accept the fuel being dispensed is equipped with a magnet in the neck of the fill pipe of the tank which will attract the magnetic valve member to hold the vent tube open, so that the automatic shut off device will not be activated by a closed valve member and fuel can be dispensed to the vehicle.
