Definitions

  • the invention relates to a lighter operated with liquefied petroleum gas, in particular a pocket lighter, which comprises a closable valve connected to a burner head at the outlet of a valve bore, a fuel tank and an adjustable measurement device for the flame height arranged between the fuel tank and the valve bore, which has a fuel-permeable metering disc made of porous material Material is provided, which is pressed on its side facing the fuel tank by means of a component having a passage opening for the fuel in its edge region tightly against an annular, preferably circular surface which encloses a recess.
  • Another object of the invention is a method for producing a lighter of the type mentioned above and includes a computer or microcomputer-controlled measurement as an integral method step.
  • a lighter of the type mentioned is known from FR-A-2397599.
  • This known lighter is a further development of the lighter known from FR-A-2313638, the maximum throughput being limited upwards by providing elastically deformable components upstream of the porous metering membrane, which cover parts of the porous membrane and thus the flow through this membrane limit.
  • Flickering of the flames can also often be observed. This applies in particular to pocket lighters, which are often exposed to very different temperatures and are usually in completely undefined transport positions immediately before use.
  • Flame regulators are known, US-A-3766946, in which an elastic body against a porous body, e.g. B. sintered metal, can be pressed and deforms itself depending on the size of the contact pressure and creates a larger or smaller surface area on the porous body and thus changes the flow cross section in the porous body.
  • a porous body e.g. B. sintered metal
  • a porous membrane for the controlled limitation of the gas flow.
  • Such devices are disclosed in FR-A-2 313 638 (with flame regulator) and FR-A-2 313 639 (without flame regulator).
  • the porous membrane which is covered at least on the side facing away from the tank with a fiber layer, and is arranged gas-tightly clamped in the valve body by means of a pressure body consisting of poorly heat-conducting plastic material.
  • the device is based on the idea that, for a satisfactory function, the side of the membrane facing the liquid gas tank should be constantly filled with the liquid phase of the gas in an exempted area, and that this liquid gas flows through the pores of the membrane to the other Evaporate the side of the liquefied gas tank with the participation of the fiber layer.
  • a wetting chamber is provided on the side of the membrane facing the tank, to which liquid gas is continuously supplied from the liquid gas tank via an immersion tube.
  • An evaporation chamber is provided on the side of the membrane covered with the fiber layer, in which the evaporation takes place when the shut-off valve located above it is opened.
  • This disclosed device does not produce fully satisfactory results by adding together several factors influencing the amount of gas actually let through, such as the inevitable fluctuations in the porosity of the membrane material and the structural scattering of the fiber material, and by the deformation of the wetting chamber diameter as a result of the contact pressure when installing the device .
  • the dip tube can form vapor bubbles in the liquid column, which, for. B. caused by changing the position of a pocket lighter, do not rule out, which among other things, a flickering of the flame or a sudden diminution of the flame occurs.
  • a precision wick is therefore used in practice in the known lighters instead of the dip tube, the manufacturing costs being significantly increased by the high cost of the wick.
  • the generic FR-A-2397599 is, as mentioned, a further development of the aforementioned FR-A-2 313 638, but is only able to limit the maximum throughput but does not guarantee a constant gas passage.
  • the present invention has for its object to provide a device that enables better constancy of the gas passage.
  • the flame index should be less than 0.9 and the flash of the flame should be avoided, which increases safety and improves the economic use of the fuel.
  • the invention should also ensure a substantial reduction in the tendency of the flame to flicker, enable a significant reduction in manufacturing costs, and moreover the device according to the invention should be easier to assemble than the previously known solutions.
  • the recess with the metering disc forms a metering chamber which is connected to the burner head exclusively by means of the valve bore and the end face of the recess in whole or in part with a permanent connection between the metering chamber and valve bore maintaining structure, which has depressions and optionally elevations, to which, when the valve is open, the microscopic single-pore metering disc made of microporous film with increasing pressure difference, which is temperature-dependent, closes more and more pores, is applied.
  • the structure of the end face contains radially extending grooves with a wedge-shaped cross section, which subsequently have peaks on their side edges, wherein the depth of the grooves based on the surface level of the unstructured surface areas (anti-glare surfaces) is a multiple, preferably five to twelve times the height with which the projections tower above this surface level.
  • the metering disc is provided with a very large number of submicroscopic, closely adjacent, preferably non-contiguous pores of slit-shaped cross section, and preferably consists of a material which, when the device is used, has its temperature-proportional properties within a temperature range from minus 30 ° to plus 70 ° C maintains fuel permeability unchanged.
  • FIG. 1 shows a partial section through a lighter, which is equipped with a measuring device according to the invention.
  • FIG. 2 shows a view of the metering space from below, on a larger scale, with the clamping disk and the metering disk removed, the FIG Section along the line III-III in Fig. 2 on a larger scale
  • Fig. 4 shows a longitudinal section of part A of Fig. 1 on a larger scale.
  • 5, 6 and 7 represent longitudinal sections through different embodiments of the dimensioning device according to the invention
  • FIG. 1 shows a testing and flanging device.
  • Fig. 1 that part of a lighter is shown in cross section, which receives the measuring device according to the invention to achieve a constant flame height.
  • a valve body 2 is pressed gas-tight into the upper wall of the liquid gas tank 1 and receives a displaceable burner tube 3 in a bore on the side facing away from the liquid gas tank.
  • the burner tube 3 has at its upper end a burner head 4, under which an operating lever 5 engages.
  • the burner tube 3 is penetrated through an axial gas outlet bore 8 opening into the burner nozzle 6 up to a transverse hole 7.
  • an elastic sealing disc 9 is arranged, which cooperates with a valve seat 10 of the valve body 2.
  • a spring presses the burner tube 3 down against the valve seat 10 and thus closes the valve bore 11.
  • a blind hole-like recess 12 is expediently machined, in which a metering disc 14 is pressed by a clamping disc 15 against a preferably flat annular surface 13 of the recess 12 is that the metering disc 14 is compressed to about half its thickness and thereby the clamping surface is gas-tight.
  • the clamping disk 15 and the metering disk are fixed in this state by flanging the edge 2a of the valve body 2.
  • the clamping disc 15 has, at least in the clamping region, a surface which geometrically matches the annular surface 13 and which ensures gas-tight clamping of the edge of the metering disc, and is connected to the liquid gas tank 1 via a gas passage opening 17.
  • the recess 12 in the valve body 2 is provided with a recess 16, the end face 2 'of the annular surface 13 of the recess 12 a distance of z. B. 0.1 mm.
  • the side of the metering disk 14 facing away from the liquid gas tank 1 forms with the recess 16 a metering space, the depth of which is two to eight times, preferably three to four times the thickness of the metering disk 14.
  • the cross section of the metering chamber 16 perpendicular to the axis of the metering disk 14 determines the size, position and shape of the area of the metering disk 14 which can be acted upon by the fuel. In general, this area will be a circular area. But it can also have a different shape. In the latter case, the diameter of an equally large circular area is referred to as the hydraulic diameter of the area deviating from the circular shape.
  • the gas passage opening 17 in the clamping disc 15 must be smaller than the hydraulic diameter of the metering chamber 16.
  • the thickness of the clamping disc 15 is smaller than the hydraulic diameter of the metering chamber 16, preferably less than a third of the hydraulic diameter.
  • the clamping disk from a metallic material, preferably from what is known as automatic brass - an alloy of 58% Cu, 2% Pb, rest Zn - since the metering disk 14 is reliably clamped due to the high pressure rigidity of such materials.
  • the valve body 2 is preferably also made of the same material, so that the thermal expansion of the parts surrounding the membrane remains the same when exposed to different temperatures.
  • the metering disc 14 consists of a microporous plastic film, the transport of liquid gas in the liquid and / or gaseous phase through the disc taking place essentially perpendicular to the surface.
  • a microporous, uniaxially stretched polypropylene film with a thickness between 15 and 40 micrometers, preferably between 22 and 27 micrometers, and with slit-shaped pores with a cross section of approximately 0.04 by 0.4 micrometers, which are formed in the extrusion direction during the stretching, are suitable.
  • a gas vapor pressure of 1 to 6 bar the amount of fuel flowing through is essentially linear to the pressure.
  • the valve body 2 is structured in FIGS. 4 and 5 on the end face 2 ', which forms the base of the metering space 16, with the exception of a peripheral region 23.
  • the structure 22 can have any relative elevations and depressions.
  • the structure can advantageously consist of radial grooves 21. 2, a four-armed slot star is shown as an exemplary embodiment. However, it is within the scope of the invention to choose any number of arms. For example, five, six or eight arms can be provided.
  • These grooves 21 are preferably embossed in a single stamping process, u. by means of an embossing tool, which has a plurality of wedge-shaped cross-sections, corresponding to the number of cups, arranged in a radial manner. As shown in FIG.
  • the depth 1 of the grooves 21 can be 0.09 mm, the opening a width k of 0.14 mm and the root m 0.03 mm.
  • the raised edge regions 22, which adjoin the edges of the grooves 21, are somewhat rough, since the structure of brass (with about 2% lead for good machinability) breaks open somewhat when it is dipped away, i. H. the grain structure is disturbed.
  • the resulting height n is approximately 0.01 mm.
  • the slot star can also be embossed by means of an embossing tool which has at least one cutting edge, the embossing tool being rotated about its longitudinal axis at a defined angle between the individual embossing processes until the desired number of arms is formed.
  • the task of the diameter of the metering chamber 16 is to clear a defined cross section of the metering billets for the gas passage.
  • the depth of the metering chamber 16 is so matched to the flexibility of the elastically deformable metering disk 14 that the desired amount of gas is let through.
  • the depth of the metering space can be matched to the unstructured surface area 23 such that if the gas pressure in the tank increases due to the temperature rise and the membrane contacts the area 23, a proportion of the pores that increases proportionally with increasing pressure is blocked, which is further reinforced by the thermal expansion of the membrane material.
  • the flame height increases to a lesser extent than the increase in gas pressure would otherwise have caused.
  • the flame index can thus be kept below 0.9.
  • a depth of the metering chamber 16 of 0.08 to 0.12 mm is advantageous, with a diameter of 1.8 to 1.9 mm of the metering chamber and a star diameter of 1.3 mm .
  • the above information relates to a quality of "Celgard R 2500 " whose porosity gives a measured value of 7.5 Gurley seconds, according to ASTM test method D-726, model B.
  • the metering disc 14 Due to its small thickness, the metering disc 14 is flexible, so that it dodges in the direction of the valve bore 11 due to the flow pressure and thereby lies against the end face 2 '. At higher temperatures and increasing pressure, due to their thermal expansion coefficient, an increasingly larger part of the metering disc 14 also lies on the non-structured area 23 of the end face 2 'without the material's yield strength being exceeded, as a result of which a portion of the pores is blocked , which is larger than a proportional portion, while the grooves 21 and the structure 22 allow the gas to flow into the valve bore 11.
  • a device according to the invention for a lighter burner results when using a "Celgard R 2500 " membrane with a Gurley measured value of 7.5, installed in a valve body with an outer diameter of 3.5 mm, a clamping disk with an outer diameter of 3 mm and a metering space with a diameter of 1.8 mm, a depth of 0.1 mm and a six-armed star with a diameter of 1.3 mm, at 25 ° C ambient temperature a flame height of 25 mm (normal flame), with about 1 milligrams of fuel per second
  • a change in the metering chamber diameter causes a proportional change in the flame height, which means that if the membrane material corresponds exactly to the desired value, a different flame height can be achieved or a corresponding one can be achieved after a deviation in the Gurley value of the membrane material batch to be used Dosing chamber diameter can be determined to achieve a desired flame height.
  • the device according to the invention for the liquid and the gaseous phase of the gas tank filling does not have a very large difference in weight of the amount of fuel passed.
  • the lighters according to the invention without an immersion tube or wick therefore permit oblique handling (for example for the purpose of lighting a tobacco pipe), the flame only becoming insignificantly larger despite the liquid tank contents coming into contact with the gas passage opening 17.
  • a calm and uniform burning of the flame in the normal upright operating position is further achieved by an arrangement of the measuring device, which means that the metering disc 14 is in direct contact with the excludes liquid phase of the container filling.
  • the lighter is lit from an undefined, for example lying, transport position into an upright position, the liquid fuel flows down to a residual amount retained by surface forces from the space in front of the metering disc 14 into the container 1, so that the metering disc 14 is separated from the liquid level 24 of the fuel.
  • the thickness of the clamping disc 15 is not greater than the hydraulic diameter of the metering space 16, the volume of the upstream space is small. Since the low surface tension and viscosity of the liquid phase of the fuel mean that the flow resistance during the outflow is low, the residual amount of fuel that may be retained, based on the cross section of the metering disc available for gas passage, is so small that it can be e.g. B. runs off, evaporated or burned in about 1 second. If a spontaneous, bubble-forming boiling of liquid fuel occurs at all on the side of the metering disk 14 facing the container 1, the amount available for this is evaporated after a short time. The gas passage through the metering disc 14 therefore takes place, apart from a very short start-up time, exclusively from the gaseous phase of the fuel, as a result of which a calm and evenly burning flame is achieved.
  • the effect can easily be enhanced by various measures.
  • the most complete possible drainage of the liquid phase when the burner is erected is favored if the surface of the clamping disk 15 is not equipped to be wettable. This can be done, for example, by coating with fluorinated hydrocarbon compounds, for example polytetrafluoroethylene.
  • the clamping disk 15 is not wettable, it is advantageous to make the diameter of the gas passage opening 17 so small in relation to the hydraulic diameter of the metering chamber 16 that capillary forces promote the outflow of the fuel from the metering chamber 16 and only small residual amounts of the liquid phase can remain .
  • the space of the gas passage opening 17 is not filled with liquid gas at all, since if the valve, as usual, was still closed when the lighter was in the upright position, no liquid gas would get into the opening, even with any pocket position that followed.
  • the clamping disc 15 has a wettable surface
  • the effect according to the invention can be enhanced if the opening 17 is designed geometrically in such a way that capillary effects are avoided.
  • the stabilization of the flame after ignition also takes place particularly quickly if the valve body 2 projects into the liquid gas tank in such a way that the size of the projection corresponds approximately to the depth of the depression 12, so that the metering disc 14 is approximately in the plane of the liquid gas tank cover 20 of the liquid gas tank 1 lies.
  • the saturation vapor pressure of the liquid gas depends on the use of e.g. B. Iso-butane not from the level of the liquid gas tank 1. Since the present invention extracts the gas from the gaseous phase of the tank filling, its effect is completely independent of the filling level of the liquid gas tank 1.
  • FIGS. 5 to 7 each of which represents a cross section through the lower part of the valve body 2 in the region of the depression 12. All reference numbers are chosen in accordance with FIG. 1 and FIG. 2.
  • the metering chamber 16 is formed by a recess in the recess 12, in the embodiment according to FIGS. 5 and 6 it is laterally delimited by a spacer ring 18 which, like the metering disk 14, is clamped gas-tight by the clamping disk 15 is.
  • the spacer ring 18 consists of a plastic material of high rigidity, compressive strength, heat resistance and preferably low thermal conductivity. Components made of polyimide, for example a type manufactured by Du Pont under the brand name “Kapton R ”, are particularly suitable for this. This material has the particular advantage that it has approximately the same thermal expansion as brass, so that when the valve body 2 and the clamping disk 15 are made of automatic brass, no thermal stresses interfere with the function of the device according to the invention.
  • the spacer ring 18 can simply be punched out of commercially available foils, which enables very cheap production and allows the diameter of the metering space to be changed comfortably.
  • the plastic material of the spacer ring 18 also promotes the sealing of the clamping surface and reduces the risk of unintentional squeezing of the metering disc 14 at the edge of the metering space 16 during assembly.
  • FIGS. 6 and 7 correspond essentially to those according to FIG. 5, but an intermediate layer 18 '(FIG. 6) is arranged between the metering disc 14 and the bottom of the recess 12, the distance between the two position 18 'formed bottom of the metering chamber 16 has the structure.
  • the intermediate system 18 ' is preferably made of the same plastic material as the spacer ring 18 and is structured on its side facing the metering disc.
  • the recess 16 is formed in a body 18 ′′, which at the same time has the function of the spacer ring 18 from FIG. 5 and the intermediate layer 18 ′ from FIG. 6.
  • the manufacturing costs of the device according to the invention are significantly reduced by the fact that no voluminous components are used which cause high material costs.
  • the costs for the mechanical processing of the components are also low, since no large quantities of material have to be removed or no machining with high requirements is to be carried out in places that are difficult to access, for example in deep blind holes.
  • the small dimensions of the components also prevent the occurrence of larger thermal expansions or thermal stresses, which impair the thermal stability of the flame height. This effect can be further improved by selecting a suitable material, which ensures the same thermal expansion coefficient for all rigid components.
  • the arrangement of thermally insulating components, such as the spacer ring 18, ensures a further improvement in the thermal stability.
  • measures for controlling flow scattering are considerably more complex, and unsuitable parts cannot be separated from usable parts by the processing and assembly that took place before they were determined to be unusable.
  • Another advantage of the device according to the invention relates to the change in the originally set flame characteristic as a result of aging, which often occurs even without use.
  • the uniaxially stretched polypropylene film is deformable in the undrawn direction, which could inadvertently affect the flow rate. It is therefore advisable to make the diameter of the valve bore 11 very small (for example 0.35 to 0.5 mm) so that the metering disc cannot be pressed in by the gas pressure.
  • a preferred embodiment of the device according to the invention uses neither a dip tube nor a wick for transporting the liquid gas to the membrane, but rather ensures a space filled with gas vapor between the liquid gas level and the underside of the valve body, the pressure body used for clamping the metering disk preferably being used as Thin clamping disc is designed to keep the volume of the gas passage opening adjoining the metering disc on the tank side small, so that the residual liquid gas retained by the surface forces runs off immediately when the lighter is brought from an undefined, for example lying transport position to ignite into an upright position.
  • the amount of liquid gas must be limited to about 80% of the volume of the fuel tank, the ambient temperature during the filling process is about 20 ° to 25 ° C. This limitation is necessary for safety reasons, since the liquid fuel in later storage or when using the lighters at much higher temperatures, such as. B. 60 ° C, could cause an explosive bursting of the container.
