Fuel dispensing spout
First Claim
1. An integrally extruded fuel dispensing spout assembly having a forward end and a rearward end comprising:
- a longitudinally extending inner member defining a passageway for carrying fuel from said rearward end to said forward end;
a longitudinally extending outer member disposed about said inner member and defining a space therebetween;
a plurality of longitudinally extending ribs defining a plurality of channels in said space;
said plurality of channels including at least one continuous longitudinal channel being used in detecting when fuel dispensation has reached a desired level, and at least a second continuous longitudinal channel being adapted for recovering fuel vapor at said forward end and carrying said recovered fuel vapor to a fuel storage compartment;
said outer member including at least one opening formed therein proximate said forward end and in communication with said at least one channel;
said outer member including at least a second opening formed therein proximate said forward and rearward of said at least one opening and in communication with said at least a second channel; and
said at least a second opening not being in communication with said at least one channel and said at least one opening not being in communication with said at least a second channel.

Abstract
A fuel dispensing spout for use in a fuel dispensing nozzle is provided. The fuel dispensing spout includes an inner cylindrical member and a concentric outer cylindrical member. The inner and outer cylindrical members are joined by a series of ribs which divide the space between the inner and outer members into a plurality of longitudinally and continually extending subchannels. Some of the subchannels are utilized for vapor recovery during operation of the spout, while one of the subchannels is utilized in detecting pressure increases in captured air contained therein as fuel dispensation takes place. The inside passageway defined by the inner cylindrical member is used for carrying fuel that is to be dispensed.
