ABSTRACT:
A liquid-dispensing nozzle has a system for blowing air for a period of time through the nozzle's spout after the liquid valve closes. The flow of air purges and expels most of the liquid adhering to the interior surface of the spout, preventing this residual liquid from contaminating either the ground on which it may fall when the spout is withdrawn from a filler pipe or the air through evaporation. The invention applies particularly well to dispensing of liquid fuels such as gasoline.
