Definitions

  • the present invention relates generally to retaining a fuel pump nozzle in a filler neck of a fuel tank while the nozzle is being used to fill the tank with fuel.
  • the present invention relates to an apparatus for retaining a fuel pump nozzle in a filler neck of a fuel tank while the nozzle is being used to fill the tank with fuel.
  • Truck fuel tanks usually include a filler neck which extends outwardly from the body of the fuel tank so that the tank can be filled with an appropriate fuel such as diesel fuel by inserting the nozzle of a fuel-dispensing pump into the filler neck and then allowing fuel to flow into the tank from the nozzle.
  • an appropriate fuel such as diesel fuel
  • the filler neck usually has an external screw thread adjacent an opening thereof which is engagable with a complementary internal screw thread of the filler cap so that the filler cap can be screwed onto and off the filler neck. After the fuel tank has been filled with fuel, the filler cap is then screwed onto the filler neck to prevent dirt and other contaminants from unintentionally entering the fuel tank.
  • diesel fuel tanks of some trucks can have capacities in excess of 2000 litres and can take up to half an hour or more to fill when diesel fuel is pumped into them at standard pump flow rates.
  • Fuel-dispensing pumps of the type which are typically provided at fuel stations sometimes have an automatic filling and shut-off mechanism which enables them to automatically fill a fuel tank and to automatically shut-off once the tank is full.
  • Fuel pumps of this type usually require a person who operates the pump to insert the nozzle of the pump into the fuel tank and to then start the pump by pulling a lever which is hinged relative to the nozzle whilst holding on to a handle from which the nozzle extends. If the operator pulls the lever by a sufficient amount, the mechanism causes the pump to continue operating and to automatically fill the tank without requiring the operator to continue depressing the lever.
  • the nozzle is usually designed so that it is able to be retained inside most normal-sized filler necks without requiring any external assistance from the operator so that after the nozzle is inserted into the filler neck and the pump is put into the automatic fill mode, the operator does not have to continue holding the nozzle inside the filler neck whilst the fuel tank is being filled.
  • the automatic filling and shut-off mechanism when used in conjunction with the self-retention of the pump nozzle inside the filler neck can substantially reduce or even eliminate operator fatigue.
  • the fuel tank filler necks of some large capacity truck fuel tanks have such large internal diameters that standard fuel pump nozzles are unable to be retained inside them without external assistance and usually require a fuel pump operator to continuously hold on to the nozzle during the whole filling process regardless of whether or not the fuel pump has an automatic filling and shut-off mechanism.
  • FIG. 1 An example of a large diameter filler neck of a large capacity truck fuel tank is depicted in figure 1.
  • the illustrated filler neck is a short length of metal cylindrical tubing which has an internal diameter of 100 millimetres and which has an external screw thread adjacent one end which is engagable with a complementary screw thread of a filler cap.
  • the diameters of large diameter filler necks can range from 50 to 150 millimetres but typical diameters are between 75 to 100 millimetres.
  • an apparatus for retaining a fuel pump nozzle in a filler neck of a fuel tank comprising an adjustable flange adapted to be inserted into the filler neck, and to retain the nozzle in the filler neck.
  • the apparatus is able to obviate the need for a fuel pump operator to have to continuously hold on to the fuel pump nozzle to prevent the nozzle from falling out of the filler neck while filling the fuel tank with fuel.
  • the adjustable flange may be any suitable shape. In a particular preferred form, the adjustable flange is generally circular.
  • the adjustable flange preferably includes a plurality of clamping members, and a biasing mechanism for pressing the clamping members against the filler neck. It is particularly preferred that the adjustable flange includes two clamping members that are hinged to each other.
  • the clamping members are preferably plates. In a particular preferred form the clamping members are arcuate plates.
  • the biasing mechanism may be any suitable type of biasing mechanism.
  • the biasing mechanism includes a compressible coil spring, a bolt extending through two of the clamping members and the spring, and a nut screwed on to the bolt.
  • the biasing mechanism includes a torsion spring secured to two of the clamping members.
  • the adjustable flange also includes a locking mechanism for limiting relative movement of the clamping members.
  • the locking mechanism includes a bolt extending through two of the clamping members, and a nut screwed on to the bolt.
  • the apparatus also includes a pipe for receiving the fuel pump nozzle, wherein the pipe is secured to one of the clamping members.
  • the pipe preferably has an outer diameter of 20 to 60 mm, and a length of 10 to 100 mm.
  • the pipe may have any suitable wall thickness. It is preferred that the apparatus also includes a cover for preventing fuel from spilling out of the filler neck.

  • Apparatus 10 is for retaining a fuel pump nozzle in a filler neck of a fuel tank, and includes an adjustable flange 11 which is adapted to be inserted into the filler neck, and to retain the fuel pump nozzle in the filler neck.
  • Adjustable flange 11 includes a pair of clamping members that are in the form of arcuate metal plates 12, 13. Each plate 12, 13 has a plurality of teeth 14 formed along an outer edge 15 of the plate 12, 13. Each plate 12, 13 also has an inner edge 16.
  • Plate 12 has a recess 17 which is adjacent to and spaced from an end of the plate 12, and which extends into the plate 12 from the inner edge 16 thereof.
  • Plate 13 has a recess 18 which is adjacent to and spaced from an end of the plate 13 and which extends into the plate 13 from the outer edge 15 thereof.
  • An end portion 19 of plate 12 is bent at right angles with respect to the rest of the plate 12, and an end portion 20 of plate 13 is bent at right angles with respect to the rest of the plate 13.
  • the recess 17 of plate 12 extends into the end portion 19 thereof, and the recess 18 of plate 13 extends into the end portion 20 thereof.
  • End portion 20 is generally L-shaped, however end portion 19 is generally T- shaped owing to the presence of a projection 21 which extends upwardly from the rest of the end portion 19.
  • a plurality of teeth 22 are also formed along an outer edge of the end portion 19.
  • the outer edge of the end portion 19 is an extension of the outer edge 15 of the plate 12.
  • Plate 12 also has an end portion 23 which is laterally offset from the plane of an adjacent portion of the plate 12 by the thickness of plate 13.
  • An end portion 24 of the plate 13 overlaps and rests on the end portion 23 of the plate 12.
  • An Allen or hex key bolt 25 extends through aligned apertures in the end portions 23, 24 and is secured relative to plates 12 and 13 by a nut (not shown) such that the plates 12, 13 are hinged to each other and are able to pivot relative to each other about the bolt 25.
  • End portion 19 extends through the recess 18 in plate 13, and end portion 20 extends through the recess 17 in plate 12 such that the ends of the plates 12, 13 which include end portions 19, 20 are interlocked.
  • Pivoting plates 12 and 13 relative to each other causes the end portions 19 and 20 to move towards or away from each other whilst remaining in the confines of the recesses 17, 18. End portions 19 and 20 contact each other when the plates 12 and 13 are pivoted away from each other as far as possible and thereby limit the amount by which the plates 12 and 13 can pivot away from each other.
  • the adjustable flange 11 also has a biasing mechanism 30.
  • Biasing mechanism 30 includes a hexagonal bolt 31 whose threaded shaft extends through a compressible coil spring 32, a first washer 33, aligned apertures in the end portions 19 and 20, a second washer 34, and a hexagonal nut 35 screwed on to the shaft of the bolt 31.
  • Spring 32 biases the plates 12, 13 to pivot away from each other when they are forced to pivot towards each other.
  • Adjustable flange 11 also includes a locking mechanism 40.
  • Locking mechanism 40 includes a hexagonal bolt 41 whose threaded shaft extends through a first washer 42, aligned apertures in the end portions 19, 20 which are different to the apertures which the shaft of bolt 31 extends through, and a second washer 43.
  • a hexagonal nut 44 is screwed on to the shaft of the bolt 41. The amount by which the plates 12 and 13 are able to be pivoted towards each other can be adjusted by suitably adjusting the position of the nut 44 along the
  • the apparatus 10 is an insert which is adapted to receive a fuel pump nozzle and to be inserted and retained inside a full tank filler neck such that when the nozzle is inserted into the neck and received by the insert, the nozzle is removably retained inside the neck by the insert so that fuel is able to flow from the nozzle and into the fuel tank from which the filler neck extends.
  • a nozzle-receiving aperture 50 of the apparatus 10 is defined by the inner edges 16 of the plates 12, 13, and is able to receive a fuel pump nozzle.
  • the size of the aperture 50 can be varied by pivoting the plates 12, 13 relative to each other. In particular, pivoting the plates 12, 13 towards each other reduces the size of the aperture 50, and pivoting the plates 12, 13 away from each other increases the size of the aperture 50.
  • the apparatus 10 is generally ring-shaped and has a generally circular perimeter which is defined by the outer edges 15 of the plates 12, 13.
  • the length of the perimeter of the apparatus 10 and therefore the diameter of the apparatus 10 can be varied by pivoting the plates 12, 13 relative to each other.
  • Figure 3 depicts a fuel filler neck 60 which has the apparatus 10 inserted therein.
  • Neck 60 is identical to the fuel filler neck depicted in figure 1.
  • Apparatus 10 is inserted into the neck 60 by firstly adjusting the position of the nut 44 along the shaft of bolt 41 so that the plates 12, 13 can be pivoted towards each other by a sufficient amount such that the outer diameter of the apparatus 10 can be reduced sufficiently to enable the apparatus 10 to be inserted into the neck 60.
