Definitions

  • the invention relates to a fluid dispensing nozzle which is connectable to a fluid reservoir for filling a tank with fluid, which fluid dispensing nozzle is provided with a through-flow channel for the fluid which debouches into a spout and with a trigger for operating at least one valve in the through-flow channel for opening and/or closing the through-flow channel, which fluid dispensing nozzle takes a modular form and comprises at least one basic module onto which at least. one further module to be chosen from a set of at least two further modules can be releasably mounted such that, subject to the chosen further module, the fluid dispensing nozzle can be made suitable for use with different types of fluid.
  • the fluid dispensing nozzle according to the invention has the advantage that it can be made suitable for different types of fluid, such as leaded or unleaded petrol, diesel, petrol mixed with alcohol, alcohol and so on, by releasable mounting of at least one further module on the basic module.
  • the basic module of the fluid dispensing nozzle according to the invention is herein the same for all types of fluid. This means a considerable simplification in the process of manufacturing fluid dispensing nozzles. Furthermore, maintenance of the different dispensing nozzles is thereby also simpler. This in turn has a favourable effect on the cost of the fluid dispensing nozzle.
  • the basic module is provided with at least a part of a vapour return channel for recovering fluid vapour and the set of further modules comprises a closing module for closing the vapour return channel and a passage module adapted for co-action with the vapour return channel for recovering the fluid vapour.
  • the closing module is particularly applicable when the fluid dispensing nozzle is to be adapted to diesel. Diesel evaporates considerably less than petrol or alcohol during filling.
  • the arranging of a passage module instead of a closing module affects the characteristic properties of the fluid dispensing nozzle to only a slight degree.
  • the fluid dispensing nozzle is a fuel nozzle
  • this is a significant advantage because the filling system of which the nozzle forms part together with a fuel pump no longer has to undergo a certification procedure by the weights and measures inspection when a closing module has been replaced by a passage module.
  • certification of a filling system by the weights and measures inspection is a costly and time-consuming affair, so that simplification thereof results in a considerable cost-saving.
  • the set of further modules comprises two or more spout modules of mutually differing diameters which can each be mounted releasably on the basic module.
  • the basic module is provided with the spout and the set of further modules comprises an adapter module, for instance in the form of an adapter sleeve, which has a larger diameter than the diameter of the spout, which adapter module can be mounted releasably over at least a part of the spout.
  • an adapter module for instance in the form of an adapter sleeve, which has a larger diameter than the diameter of the spout, which adapter module can be mounted releasably over at least a part of the spout.
  • a narrower spout diameter is for instance required for unleaded petrol than for leaded petrol, petrol with lead substitute or diesel.
  • the latter alternative, preferred embodiment moreover has the advantage that the changing of the spout diameter by means of the adapter module can be performed without this having consequences for the characteristic of the fluid dispensing nozzle.
  • the invention also relates to a module, such as a basic module, a closing module, a passage module, a spout module or an adapter module, evidently intended for use in a fluid dispensing nozzle according to the invention.

  • Received in main valve 11 is an auxiliary valve 12 which opens an auxiliary through-flow opening for the fuel.
  • Auxiliary valve 12 is coupled to rod 16 which runs through the main valve and is movable therein.
  • Rod 16 is coupled for movement to trigger 13.
  • Rod 16 is provided with a stop 17 against which rest first biasing means 14 and second biasing means 15.
  • Biasing means 14 and 15 are spring means.
  • First biasing means 14 engage on the other side thereof on the seat 18 of main valve 11.
  • Second biasing means 15 engage on the other side thereof on the main valve 11 itself.
  • the operation of the nozzle is as follows.
  • the user By exerting a relatively small force on handle 13 the user opens auxiliary valve 12 through movement of rod 16.
  • This opened situation of the auxiliary valve is shown in figure 3.
  • first and second biasing means 14 and 15 are biased.
  • the quantity of fuel which flows through the auxiliary through-flow opening preferably lies in the range of 10 to 50% of the maximum fuel flow through the nozzle.
  • the dimensions of the auxiliary through-flow opening and the main through-flow opening are more preferably such that approximately 25% of the maximum fuel flows through the auxiliary through- flow opening.
  • the main valve then opens automatically counter to the direction of flow.
  • This opened situation of the main valve is shown in figure 4.
  • auxiliary valve 12 By squeezing handle 13 still further inward, auxiliary valve 12 can be moved from its now closed position to its open position. This situation is shown in figure 5.
  • the fuel flow rate is now maximal.
  • Figure 6 shows a graph in which line 19 schematically represents the force F which must be exerted by a user on the trigger plotted against the stroke S of rod 16.
  • Figure 7 shows a graph in which line 20 schematically represents the fuel flow V plotted against the stroke of valve rod 16.
  • the transition point in both graphs is caused by springing open of the main valve. It can be seen clearly that the force to be exerted remains within certain limits over the whole range of the stroke. At both a low fuel flow and at a high fuel flow the user can suffice with a relatively low actuating force.
  • the convenience of operation of the nozzle according to the invention is thereby improved considerably relative to that of the known nozzle.
  • the nozzle according to the invention is adapted to suck up evaporated fuel during filling.
  • Vapour return channel 8 can be closed using a ball-like closure body 30.
  • Ball 30 is arranged in a claw 33 which is placed shiftably in the line of vapour return channel 8.
  • Trigger 13 is coupled on one side thereof to lever 31 which in turn is coupled rotatably to claw member 33 via rotation point 34.
  • Lever 31 consists of two arms 31A and 3IB which are mutually connected at connecting point 35.
  • Point 35 can function as a rotation point depending on the position of detection means in the form of membrane 32 and of spacer elements in the form of rollers or rods 36.
  • Point 35 is placed displaceably in the line of rod 16. It is noted that lever arms 31A and 3IB are shown in figure 1 but in figures 2-5 and 12 they are only shown schematically with broken lines.
  • vapour suction system The operation of the vapour suction system according to the invention is as follows.
  • the nozzle 10 is ready for use and all movable parts are situated in the rest position.
  • Ball 30 closes vapour return channel 8.
  • Membrane 32 is also situated in the rest position. This is also the case for rollers 36.
  • Rotation point 35 has no fixed position, so that when trigger 13 is squeezed lever 31 can rotate freely on rotation point 34. No shifting of claw member 33 herein takes place and ball 30 remains in the shown position, so that vapour return channel 8 remains closed.
  • Closure of the vapour return channel is moreover position-dependent. When the nozzle is hung in the holder of the pump, ball 30 will close the vapour return channel.
  • FIG 8 shows a detailed side cross-sectional view of the end valve of the nozzle according to the invention.
  • Figure 9 shows the end valve of figure 8 in top cross-sectional view.
  • End valve 21 takes a form such that, in co-action with the inner wall of spout 5 and seat 22 of the end valve, it forms part of a venturi . Underpressure is created by the venturi subject to the quantity of outflowing fuel. The venturi co-acts with the switch-off mechanism, this being elucidated hereinbelow.
  • the shape of end valve 21 is substantially conical. This shape tapers approximately conically from the middle of the end valve to the outer ends thereof. End valve 21 is arranged movably on shaft 23. Spring means 24 are arranged in end valve 21.
  • baffle element 26 is situated at the rear which, in the closed situation of end valve 21, closes the opening 29 of the delivery end of spout 5.
  • Body 26 reduces turbulence in the fuel flow as much as possible and, due to the shape thereof, supports opening of the end valve under the influence of the fluid flow.
  • P- J Hi I 0 is PJ P- Pi P- O P- H rt 0 ⁇ 0
  • Hose connecting module 38 provides a rotary coupling between nozzle 1 and hose 42 which prevents twisting of the hose. Twisting of the hose is undesirable because it results in loops in the hose when the nozzle hangs in the holder on the pump. In addition, lateral forces occur on a twisted hose during filling, which is inconvenient.
  • the dimensions of nut 41 can of course be adapted to any type of hose. It will be apparent that in addition to the illustrated and described embodiment of a nozzle for fuel, many more other embodiments of the fluid dispensing nozzle can be realized according to the invention which fall within the scope of the appended claims .
