Patent ID: 8079829

Claim:
In a fuel delivery assembly having a storage tank for the fuel, a superstructure mounted upon the storage tank, a leak detector for receiving fuel to be dispensed from a chamber in the superstructure, the improvement comprising: a) an in-line motor and pump assembly for pumping fuel from the storage tank to the chamber, said in-line motor and pump assembly including a brushless direct current motor; b) a pipe and an internal conduit defining a first annular passageway for conveying the fuel from said in-line motor and pump assembly to the chamber; c) said in-line motor and pump assembly including a common shaft and upper and lower journal bearings for supporting the rotor of said motor and an impeller of said pump; d) an inlet section upstream of said impeller, said lower journal bearing and a thrust bearing for supporting a lower end of said shaft and at least one passageway for conveying fuel into said inlet section via said lower journal bearing and said thrust bearing to lubricate and cool said lower journal bearing and said thrust bearing; e) a throat unit defining a throat adapted in configuration to said impeller for conveying the fuel in response to rotation of said impeller; f) a motor mount assembly for mounting the stator of said motor; g) a housing in combination with said motor mount assembly for defining a second annular passageway to receive fuel from said throat and convey the fuel adjacent said stator to draw heat from said stator to cool said motor and through said lower journal bearings for purposes of lubrication and cooling; and h) a tube holder attached to said motor mount assembly for channeling flow of fuel from said second annular passageway to said first annular passageway.
