ABSTRACT:
A discharge spout tip for a fuel-dispensing nozzle wherein the outlet end of the tip has a cross-sectional area approximately equal to that of the discharge spout inwardly of the tip and wherein the tip has a downwardly sloping, upper surface for deflecting fuel flowing through the outlet end of the tip in a generally downward direction at an effective angle of deflection from the center line of the discharge spout so that the fuel flow is directed away from the upper surface of the fill pipe in order to prevent the formation of a liquid barrier in the fill pipe. By reducing or eliminating the liquid barrier in the fill pipe, the likelihood of occurrence of a spitback or spill is reduced. The fuel-deflecting surface of the tip may be formed by positioning a wedge-shaped projection on the upper surface of the tip, and alternately, the upper surface of the tip itself may slope downwardly from a point on said discharge spout to form a fuel-deflecting surface.
