Definitions

  • the filler tube further includes a terminal rim at the outer edge to removably receive a closure cap.
  • the vapor seal member includes a peripheral lip which firmly engages said terminal rim of said filler tube.
  • a central resilient segment of the seal member defines an access opening adapted to slidably receive the discharge tube of the nozzle whereby to form an annular vapor tight seal with the latter and thus avoid passage of fuel vapors from the tank.
  • VAPOR SEAL FOR FUEL TANK FILLER TUBE BACKGROUND OF THE INVENTION During the fueling of a motor vehicle such as an automobile, boat, airplane or the like, a vaporizable fuel in liquid phase is normally introduced to the fuel tank in a pressurized stream.
  • the normal automotive vehicle will be utilized to illustrate the novel fuel system.
  • the automotive gas tank is carried at some point within the vehicle such that the filler spout inlet protrudes at a point where it is readily accessible to a fuel dispensing nozzle.
  • the latter is provided with means to sealably engage a filling nozzle during the tank filling operation.
  • insertion of said dispensing nozzle into the filler spout immediately forms a vapor tight annular seal to in effect define a substantially confined fuel systern.
  • FIG. 1 illustrates the invention, in partial cross section, in conjunction with a fuel dispensing nozzle prior to engagement of the nozzle with the tank filler spout.
  • FIG 2 is a segmentary view in partial cross section and on an enlarged scale showing a fuel tank filler spout.
  • FIG. 3 is an enlarged segmentary section showing a discharge tube in registry with an adapter during a fuel transfer operation.
  • FIG. 4 is an end view with part broken away, of FIG. 3.
  • a vehicle fuel tank 10 of the type contemplated includes a generally closed metallic receptacle. The latter is supported on the vehicle such that it can be readily filled, and communicated with the vehicles engine.
  • Said tank 10 thus includes an elongated filler spout or fuel conduit 1 I that is commu nicated at one end with the tank interior, and so formed to terminate at a point of the vehicle exterior where it may be removably engaged by a fuel dispensing nozzle 12.
  • fuel dispensing nozzle 12 includes in essence a means such as a flexible hose I3 communicating said nozzle with a pressurized source of a volatile fuel.
  • a control valve within the nozzle is manually operable to regulate the flow of fuel from the source thereof into an elongated, slightly curved discharge tube 14.
  • the control valve in the normal manner, is actuated through a manually adjusted lever 16 such that an operator can vary the volume of fuel flow, or fix said lever 16 to permit a steady, continuous flow.
  • venting means is communicated with tank 10 or with filler spout 11. Vapors are thereafter conducted to a closed receptacle, or preferably condensed into liquid form and passed to the pressurized fuel source to be recirculated into tank 10.
  • such vapor collecting means can be through nozzle 12 and associated condensing apparatus.
  • Filler spout I1 is normally cylindrical in general configuration, the remote end thereof being so sloped as to receive a fuel nozzle and to hold the latter in place during the fuel transfer operation.
  • filler spout 11 extends in a generally upward direction having an inlet 17 at the remote end which includes an inwardly turned rim or lip 18.
  • the latter embodies slots or the like on the facing edge, formed therein to accommodate corresponding locking tabs as will be herein noted.
  • a cap 19 comprises in essence a removable closure means adapted to be aligned with the upper end of said filler spout II. A partial rotation of the cap fastens the latter into place whereby to avoid leakage of either liquid or vapors from the tank. Said cap can also be provided with emergency vapor venting means such as an opening or valve whereby to avoid pressure build-up in tank 10.
  • cap 19 is rotatably disconnected from its fixed position and removed from the filler spout inlet 17. At this point of the operation, fuel vapors confined in the tank will be free to pass to the atmosphere. However, with introduction of the fuel nozzle discharge tube 14 into filler spout 11, entry of the liquid fuel to the latter will cause residual vapors to rise up along the filler spout and pass into the atmo sphere.
  • the terminal or remote end of filler spout 11 is provided with an adapter member 2].
  • Adapter member 21 includes in essence a relatively elongated central section 22, having an enlarged open ing 23 at one end, and a constricted opening 24 at the other or inner end. Said respective openings 23 and 24 are connected by a frusto conical or tapered portion 26 that defines a smoothly curved surface.
  • Central section 22 is designed to slidably receive the inserted nozzle discharge tube 14 which is guided along the tapered portion 26 toward the smaller or sealing segment at opening 24.
  • the walls of said section 24 are sufficiently resilient to maintain a close fit and to define an annular seal about the said discharge tube periphery. The connection thereby defines a barrier to passage of vapors from fuel tank 10.
  • the entire central member 22 is formed of a material sufficiently resilient to freely pass the nozzle, and to form a vapor tight seal therewith.
  • Said material is necessarily not only durable, but resistant to deteri ration when contacted with the volatile fuel, or with other liquids that might be added to or introduced to fuel tank 10.
  • One form of such material includes a thermal plastic such as Neoprene, Nitrile, Viton, Buna N or the like which, under a wide range of atmospheric temperatures, will maintain their resilient characteristics to form the necessary annular seal as discharge tube 14 is repeatedly registered therewith.
  • the walls thereof can be provided adapter, or more, and preferably a plurality of stiffener strips 27.
  • the latter can be moulded directly into the walls of the central member extending from the inlet end 23, to the smaller discharge opening 24.
  • Said stiffeners can also be formed along the exterior surface of member 21 whereby to achieve the necessary strengthening of the unit.
  • said adapter is provided with a ring 28 which is fastened along a lateral engaging surface to a corresponding wall of central section 22.
  • Said ring 28 includes an upstanding annular rim 29, so formed about its periphery to engage the corresponding engaging lip 18 of filler spout 11 in a forced or tight fit.
  • An extended portion of said ring 28 further includes a peripheral segment 31, which is presently shown inwardly formed, but could be formed to define a circular seat 32 to receive and lock the cap 19.
  • Said receiving seat 32 includes peripherally spaced openings or slots 33, which are so shaped and spaced apart with respect to each other, to receive corresponding locking tabs 34 depending from cap 19.
  • nozzle 12 is urged into adapter 21 such that a substantial length of tube 14 is within spout ll.
  • Adapter 21 will as shown be deformed primarily at constricted opening 24. However, the weight of the nozzle will cause the latter to drop, whereby the outer end of tube 14 will engage the inner wall of spout
  • the upper end of tapered section 22 is provided with one or more, and preferably a series of valves 37.
  • the latter include a movable element that is displaceable when subjected to excessive pressure in the tank. Therefore in the event that fuel vapors are not removed from tank 10 at a sufiiciently rapid rate, venting through valves 37 will avoid an undesirable pressure build-up within the tank.
  • Tank 10 thus can be relatively full of liquid with but a small residual volume of vapor remaining within the filler spout 11.
  • filler spout 11 will be momentarily exposed to the atmosphere resulting in a minor amount of fuel vaporization and passage of said vapors to the atmosphere.
  • vapor passage will be terminated upon the replacement of nozzle cap 19 in its desired position in engagement with adapter 21.
  • a volatile fuel is transferred from a storage means therefor to a vehicle tank by way of a dispensing nozzle removably communicated with said vehicle tank, the latter having a filler spout adapted to receive a discharge tube of said dispensing nozzle, the improvement therein for establishing a disconnectable vapor tight seal while said dispensing nozzle and filler spout are in engagement comprising:
  • an elongated resilient wall adapter having an inlet at one end thereof, and being fixedly retained by a circular neck connected to said filler spout to prevent axial movement therebetween, said adapter having a sealing portion disposed within said filler spout thereby defining an expandable longitudinal passage, the latter being outwardly expandable to form a vapor tight annular seal about said nozzle discharge tube while being spaced from the inner wall of said filler spout thereby defining an annular opening extending the length of said sealing portion when said discharge tube is removably registered in said longitudinal passage, and said adapter being laterally displaceable along said sealing portion into said annular opening to allow a limited degree of pivotal movement of said dispensing nozzle of circular neck when said nozzle discharge tube is so registered within said filler spout,
  • said adapter expandable longitudinal passage includes; an inlet opening having a substantially larger diameter than said elongated sealing portion of said adapter.
  • said expandable longitudinal passage includes longitudinally aligned; stiffener means formed therein to maintain the shape of said longitudinal passage.
  • said adapter includes; a tapered segment having an enlarged inlet end, forming said expandable longitudinal passage.
  • valve means in said resilient wall adapter being displaceable in response to internal pressure to an open position whereby to vent excessive pressure accumulation within said fuel tank.
