<p>An improved fuel dispensing nozzle (10) of significantly reduced size and weight has a single diaphragm (94) that provides the vapor regulating function as well as providing the excess pressure and excess vacuum shut-off functions. Improved shut-off function is obtained by ensuring that chamber pressure is the same as that at the spout tip (32) disposed in the vehicle fuel tank fill pipe. The improved fuel dispensing nozzle (10) design also reduces the amount of accidental fuel spillage which may occur when refueling is concluded.</p> |
