Abstract
A vacuum assist nozzle with a vapor recovery system is provided with an automatic vapor return shut-off mechanism to turn off or disable the nozzle's vapor recovery system when the nozzle is placed in the fill pipe of a vehicle having an on-board vapor recovery system. The nozzle includes a diaphragm valve placed in the nozzle's vapor flow path. The diaphragm nozzle control chamber is placed in communication with the vapor flow path. A vent tube, which forms the vapor flow path in the spout, includes a tip valve at the end thereof. The tip valve is magnetically operated, and is responsive to the presence of a magnetic field in the vehicle's fill neck, to enable or disable the vapor recovery system of the nozzle.
