Definitions

  • the present invention relates to a gun for dispensing liquids and more particularly fuels in a capacity that does not have an external filler neck. More specifically, the invention applies to the distribution of fuel in petrol stations and relates to a fuel dispensing device for vehicles equipped with tanks having no external filling troughs that is to say for other vehicles than cars, buses and trucks.
  • fuel will be used to cover all families of fuels such as gasoline, unleaded gasoline, diesel, biofuels alone or in mixture necessary for the refueling of a motor vehicle.
  • motorcycle will be used to cover all motor vehicles whose fuel tank does not have an external filler such as two-wheel vehicles, motorcycles, mopeds, scooters, mini-motorcycles, motorcycles for child, three-wheeled motorcycle, four-wheeled motorcycle type quad or kart.
  • capacity will be used to cover all containers, drums, jerry cans, tanks capable of containing a liquid, preferably a fuel.
  • dispensing guns for motor vehicles are connected by a flexible pipe to a distribution terminal consisting mainly of a volumetric counting machine and a positive displacement pump connected to buried tanks.
  • the dispensing guns consist of a gripping handle and a filling pipe subsequently called spout.
  • the fuel distribution is obtained by opening a shutter valve actuated by manual control of a trigger located in the pistol grip.
  • the spout contains a small diameter overflow pipe which, as soon as it fills with fuel, causes the trigger to lock.
  • the French standard NF ISO 9159 and the international standard ISO 9159: 1988 regulate the dimensions and flow rates of pistols for the distribution of leaded petrol and diesel while the NF ISO 9158 standard and the international ISO standard. 9158: 1988 regulate guns for the distribution of unleaded gasoline.
  • the flow of the gun must be less than 50 Liters per minute
  • the length of the spout, defined as the clearance between the free end of the fuel flow and the body of the gun, must be 165 mm at minimum and the bending angle ⁇ u bec of 21 degrees ⁇ 1.5 degrees.
  • the present invention aims to solve the problems encountered and discussed above.
  • the present invention therefore proposes a device for the distribution of liquid, capable of safely filling capacities directly open to the atmosphere, that is to say the opening of which is not extended by an external filler neck.
  • the invention therefore relates to a gun for dispensing liquid, preferably a fuel, comprising a liquid inlet connected to a supply hose, a handle and a pouring spout, said spout comprising two portions, a connected portion to the body of the gun and a portion having a free end, these two portions having a bending angle ranging from 22.5 to 90 degrees, said portion having a free end of fuel flow having a length ranging from 40 to 60 mm, in particular between 45 to 55 mm.
  • the bending angle can range from 22.5 to 40 degrees, in particular 25 to 35 degrees, or even equal to about 25 degrees.
  • the gun may have a length (L) of at most 155 mm, preferably between 120 and 150 mm, more preferably between 130 and 140 mm.
  • This length (L) can be defined as the clearance between the free end of the fuel flow and the body of the gun, in particular the distance between the plane passing through the plane of the orifice of the free end and the parallel plane passing through the center of the junction between the gun body and the spout.
  • the bending angle ⁇ of said spout may be arranged at distances L 2 from the handle, more specifically from the gun body and L 1 from the free end of the fuel flow of said spout such that the ratio L 2 / L 1 varies from 0.5 to 2, preferably 1 to 2, more preferably 1.5 to 2.
  • the distribution of the liquid is obtained by manual control of a trigger located in the pistol grip for dispensing liquid
  • the invention further relates to the use of said gun for dispensing liquid for filling capacity without having an external filler neck.
  • the invention relates to the use of said gun for refueling a vehicle whose tank does not have an external filler neck.
  • said gun can be used for dispensing liquid whose pump flow rate is between 30 and 35 liters per minute, preferably between 30 and 33 liters per minute.
  • the spray gun for the liquid distribution 1 consists essentially of a liquid inlet 3, a gripping handle 4 and a spout 6 made of any type of conductive material (x) ( s) resistant to hydrocarbons such as metals.
  • the length L of the spout extending from the free end of the fuel flow to the body 2 of the gun must be at most 155 mm and the bending angle ⁇ between 22.5 and 90 degrees.
  • the length of the spout L is between 120 and 150 mm. More preferably, the length of the spout L is between 130 and 140 mm.
  • the bending angle ( ⁇ ) formed by the portions A and B is preferably between 22.5 and 40 degrees. More preferably, the bending angle ( ⁇ ) is between 25 and 35 degrees, preferably the bending angle ( ⁇ ) is about 25 degrees.
  • the pouring spout may be equipped with at least one projection forming a stop called spigot or stopper 7.
  • the spout 6 is equipped with a single stop abutment 7.
  • Said abutment (s) 7 is (are) positioned (s) on the portion B of the spout extending from the handle, specifically the body 2 of the gun to initiating the re-entrant angle or obturating curvature of the spout, preferably until the initiation of the obtuse angle of curvature of the spout.
  • the spout 6 may be equipped with a device for recovering these vapors. Indeed, it appears that the reduction of the dimensions of the spout and the stabilization thereof on the edge of the tank via a stopper improves the efficiency of devices usually used to suck the vapors.
  • the joining portion between portions A and B, in which the vapor recovery device may be located, may also constitute, in itself, a stopper.
  • the free end of the spout 6 may be equipped with a protective cap.
  • the protective cap may be a protective ring that encloses a portion of the free end of the portion A of the spout 6.
  • Said protective cap is made of any type of electrically conductive synthetic material capable of resist corrosive chemicals and especially fuels.
  • the positioning of said protective tip on the spout can be performed by a snap fit, gluing, screwing or any other suitable method.
  • the positioning of the protective tip is made by clipping on the free end of the grooved spout for this purpose.
  • the flow of liquid fluid upstream of the spout 6 can be decreased.
  • Prototype tests show that the length of the spout influences the flow setting. This is because reducing the length of the nozzle has the effect of limiting fuel turbulence in the tank.
  • a length L of at most 155 mm from the spout preferably from 120 to 150 mm, more preferably from 130 to 140, corresponds to an optimum pump flow of 30 to 35 liters per minute, preferably 30 to 35 at 33 liters per minute.
  • the reduction of the dimensions of the spout 6 combined with the optimization of the flow has a positive effect on the storage of fuel in the spout after interruption of the flow rate by limiting it strongly.
  • the spout no longer drops unexpectedly.
  • the constitution of dispensing guns is simplified because it is not necessarily necessary to equip the guns with anti-drip device. This improvement, however, does not prevent equipping the spout with an anti-drip device.
  • Said device may be produced in accordance with the devices described in the patent FR2731690 TOTAL RAFFINAGE DISTRIBUTION or in the patent FR2714900 of ELF ANTAR France and NORMAND INDUSTRIAL EQUIPMENT.
  • the dispensing gun according to the invention is particularly suitable for tanks of road vehicles having no filler neck and preferably having a low capacity, in particular less than 25 liters. However, it can be used to fill capacities equipped with filler neck and any capacity. Similarly, the dispensing gun according to the invention is particularly suitable for dispensing fuel but can equally well distribute other types of liquids alone or in a mixture such as oils or alcohols.
  • Table 1 shows the general and preferred dimensions of the spout 6 of the dispensing gun 1.
  • TABLE 1 Spout dimensions
  • Preferred dimensions The 120 to 150 mm 130 mm to 140 mm AT L1 40 to 60 mm 45 to 55 mm D1 21.3 mm max.
