Patent attributes
A fuel dispensing nozzle has a body with a spout, which together define a passageway for flow of fuel from a hose connected to a fuel dispenser, through the spout, and into a vehicle fuel tank fill pipe. A boot surrounding the spout defines an outer rim that engages a surface surrounding the fill pipe. A valve within the nozzle body starts and stops flow of fuel through the passageway. An anti-spitting lockout assembly resists opening of the valve, but a linkage mechanism triggers release of the lockout assembly when the boot rim engages the surface surrounding the fill pipe, signaling insertion of the spout into the fill pipe, to permit actuation of valve. In a preferred implementation, the anti-spitting lockout assembly resists opening of the valve to permit flow of fuel through the passageway to the spout until the boot rim engages the surface surrounding the fill pipe, signaling insertion of the spout, thereby to prevent spitting of liquid fuel from the spout due to premature release of liquid fuel held under residual pressure in the hose. A fuel dispenser assembly including this fuel dispensing nozzle is also described.
