Definitions

  • the fuel flow path in Fig. 1 is indicated by outline arrows and dashed line 32. It will be seen that fuel flows from the central hose passage, defined by tube 30, though the nozzle body 24 and then though the spout assembly 22 for discharge from the distal end of the spout 22.
  • the spout 22 is compositely formed and comprises a spout assembly that includes an outer tube 34 and an inner tube 36.
  • the inner tube 36 defines the fuel flow path through the spout assembly.
  • the inner and outer tubes combine to define a flow path longitudinally through the spout assembly. This flow path is generally annular, although the inner tube 36 is not necessarily concentric of the outer tube 34 at all points along its length.
  • the next operation in the lathe procedures is turning a groove 62 in its inner end portion.
  • the groove 62 referenced as a breakaway fracture groove, provides a predetermined failure mode in the event a vehicle is driven away from a fuel dispenser with the spout still inserted in the fill pipe of its fuel tank.
  • the provision of a breakaway groove is a well known expedient.
  • the present invention departs from prior teachings in that the groove is formed during the setup for lathe procedures and prior to bending the spout to angle the distal end portion relative to the inner portion thereof, as will next be described in connection with the present spout tube 34.
  • nozzle components with which the spout assembly cooperate will next be described, with reference to Figs. 5 and 6.
  • a scuff guard 85 of relatively soft, vinyl plastic Prior to such description it will be pointed out that the major portions of the nozzle body 24 and vapor cap 41 are enclosed within a scuff guard 85 of relatively soft, vinyl plastic.
  • the scuff guard embodies known teachings.
  • the described construction uniquely minimizes flow losses at the connection of the three fluid passages (fuel, vapor and venting air) in the spout to the corresponding passages in the adapter. Further, in so connecting such passages, a compact space envelope is maintained, all to the end of providing a nozzle that can be used by a service station customer with the same convenience as found in a conventional nozzle that does not have a vapor recovery capability.
  • Figs. 15-17 illustrate a spout assembly 22' that is also shown in the above-referenced application, Ser. No. 986,521.
  • the spout assembly 22' is, likewise, adapted to be mounted on a nozzle body (not shown) to provide a fuel dispensing nozzle having a vapor recovery capability.
  • the spout assembly 22' comprises an outer tube 34' and an inner tube 36'.
  • the inner tube 36' defines the spout portion of a fuel passage 32' and combines with the outer tube 34' to define an annular, vapor return passage 40'.
  • Holes 38', in the tube 34', adjacent its distal end, provide an entrance to the vapor return passage 40'.
  • Figs. 23-26 illustrate an alternate approach to strengthen the outer end portion of the outer spout tube.
  • This spout construction identified by referenced character 222', may be the same as the spout construction 222, just described except for the outer end tube portion 234B.
  • the tube portion 234B' is preferably formed from an extruded aluminum tube, which has longitudinal strengthening ribs 241.
  • the ribs 241 permit the economical use of extruded aluminum tubing, with a minimum of machining, to form the tube portion 234B'.
