Description
The present invention relates to a device for limiting the gas flowrate in a liquefied-gas lighter.
0~ the various devices proposed to limit the yas flowrate in a liquefied-gas lighter, a perforated hollow cylinder is known, inside which an assembly, composed of a compression part and a wick surrounding this compression part, is crimped. .
Such a device i5 suficient to prevent the lighter frcm flaring up dangerously. However, due to the wick geometry in particular, it does not enable a flowrate of approximatel~
400 mm3 per second in the gaseous phase, corresponcling to a flowrate of a~out 1.~ mm3 in the liquid phase r to be limited to ~ precise value.
This is why a device wherein the wick is replacea by a compressible per~eable pellet, whose cross section corresponds substanti.ally to the cross section of the hollow perforatea cylinder, has also been proposed.
In this way it is possible to o~tain more precise compres-sion of the pellelt ~han in the case of the wick ancl hence a better controlled gas flowrate.
This compression is obtained either by crimping, as in the case of the wick, or by anchoring an intermediake. part due to the presence thereon of teeth engaging the innex wall of the hollow cylinder, or by orce fitting.
This device can be used in an adjustable-flame lighter to limit the flame height7 but it is insufficiently precise to be usable in liyhters with no flame-height adjustment. In such .,,~ .q~.
3~¢~
lighters, the Elame, which cannot be adjusted, must have stable characteristics, height in particular, from the time it is assembled.
In the case of crimping, this is done in the same direc-tion as the compression of the permeable pellet. For crimping to be effective, it is necessary for the crimps or their equivalents to have a certain elasticity. As a result, when the tool releases the crimps they spring back because of their elas~icity and this movement modifies the compression of the permeable pellet and hence the gas flowrate.
It would obviously be possible to go beyond the proper position so that the crimps would return to this position when they sprang back. However, the unavoidable tolerances, particularly with regard to the elastic characteristics of these crimps, would not permit an identical degree of recoil to be obtained with each lighter.
The other methods which consist of anchoring the inter-mediate part within the inner wall of the hollow cylinder or of force-fitting it, have the same disadvantage, namely the intermediate part moves back when the inserting tool is removed.
The purpose of the present invention is to overcome these disadvantages by proposing a device to limit the gas flowrate in a liquefied-gas lighter such that it can be set very precisely and that this setting can become permanent.
The present invention provides a device for limiting the gas flow in a liquefied gas lighter, the device including a compres-sible permeable mass compressed by compressive forces between first and second parts fixed with respect to each other, and means immo-bilizing the first and second parts relative to each other, in 28 which the immobili~ing means act in a direction perpendicular to

Thus, it becomes possible to adjust the compression of the permeable mass very precisely with no risk of subsequent maladjustment and, under these circumstances, a device according to the invention can be used both for an adjustable-flame lighter and for a lighter with a nonadjustable flame.

~S9'76 Figure 12 is an axial section of a flame-control device equipped wi h a device accordins to the invention.
I~ F~gures 1 and 2, the two compressin~ parts are composed of a hollow cylinder 3 and a compressing part propex, 1. Com-pressîng part 1, which is cylindrical and has six lengthwise grooves 4, is welded inside cylinder 3.
A.~ass of permea~lP compressible material 2 is com.pressed to à desired value between compressing part 1 and bottom S of cylinder 3, perforated at 6.
The following method can be used to manufactuxe such a device~
--i.n stage one, a m~tal compressing part 1 is coated with hard, low-melting-point solder except at the ends and in grooves 4, which ~ust .remain uncoated;
... .
- i.n st;age two, permeable mass 2 and compressing part 1 are inserted into cylinder 3;
- ln stage three, the a~sembly is placed in a flow-measuring system, ~or example for nitrogen, passing thr~ugh permeable mass 2, ana a devi~e known- of itsel ensures ~hat compressing part 1 is thrust against bottom 5 of cylinder 3 until the c~mpression of permeable mass 2 produces the desired rate of flow;
- in stage four, when each part is immobile, heat is appli`ed - so that the hard solder melts, thus joining compressing par~ 1 to cylinder 3: any known means of producing local heating can be usea, such as a laser or electron bombardment.
Once cool/ the device is ready to be used in a l~ghter as will be shown hereinbelow in the discussion of Figure 11.
Figures 3 and 4 show an alternative embodiment wherein a compressing part 11, with a star-shaped cross section, is ~ 5 5~
immobilized inside a hollow cylinder 13, ensuring compression of a permeabIe mass 12 against bottom 15~ perforated at 16, of cylinder 13.
The points of the star formed by the cross section of com-pressing part 11 are such that, when ~he skirt of cylinder 13 grips compressing part 11, they leave a lengthwise groove 14 between two adjacent points.
Such a device can ~e made by a method su~stantially analogous to that described ~ propos of Figures 1 and 2~ forming compressing part 11, inserting permeable mass 12 and compressing part 11 inside cylinder 13, compressing mass 12 until the desired flow~ate is obtained, and forcing cy~inder skirt 13 over cornpressing part 11, th~s t~ght grip -~eing ach~eved by an external means, electro-forming,- for ex~mple.
Figures 5, 6, ~, a~d 8 illustrate a version ~herein ~om-pressing parts ~l and 23 are made integral by elastic radial deformation.
Compressin~ part 21, which has a gas-flow groo~e 24, is sliyhtl~
greater in diameter than the inside diameter of cylinder 23. ~he sk;rt of cylinder 23 is made of a material su~ficiently elastic to deform slightly when compressing part 21 passes through when the latter is installed, and to relax thereafter or even prac-tically resumë its original geometry.
When compressing part 21 is in place, it compresses permeable mass ~2 to the desired degree against the bottom 25 of cylinder 23, which bottom is provided with a central gas-flo~ orifice 26.
' . ~ 6 S~:376 Because of the elasticity of the skirt of cylinder 23, compressin~ part 21 does no~ recoil when the tool which inserts this part into cylinder 23 has ceased to act.
Hence, in such an embodiment, no supplemen~ary operat.ion is necessary to ensure integration of compressing part 21 and cylinder ~3.
Figures 9 and 10 show an alternative means of joining the compressin~ parts by elastic radial deformationO
The dev.ice illustrated has a ~R 36 proviaed with a ~entral 37 which positions a washer 32 made of compressible permea~le material.
This assembly is held inside a bore 35 of a lighter ~ody 33, of which only a small part is shown~ by a longitudinally rigid rad~ally elastic compress~ng part 31 due to the presence of three inkernal members 34 which tend to force part 31 ~gain5t the ~ail of bore 35.
Figure.ll'sho~s an example of how the device accoxding to the invention is used in a li~hter without an adjustable flame.
This device has a compressing part 41 integral.with a ho}low metal cylinder 43, these two parts compressing a permeable c~m~
pressi~le mass 42 to a desired degree. It is placed in a well .
47 in body 48 of a lighter and abuts an internal shouldex 49 o~
~his well.
A burner 40 provided with a flap valve is disposed above cylinder 43 in a manner known of it5elf. By means of an elastic .
5~
device not shown in the figure and not part of the invention, burner 40 rests on bottom 45 of cylinder 43 in such a way as to block orifice 46 by means of the burner flap valve.
In a traditional fashion, the lighter also has a device, not shown in the figure and not part of the invention, enabling burner 40 to be raised and the lighter gas to be freed for use.
The path of the gas is as follows: passage through grooves 44 of compressing part 41, passage through permeable compressible mass 42, passage through orifice 46 in the bottom 45 of cylinder 43, and exit via the central duct in burner 40.
It is obvious that the flowrate of the gas so released will be a function of the degree of compression of mass 42 of the permeable compressible material.
Figure 12 gives an example of how the device according to the invention is used in a device for adjusting lighter-flame height.
This embodiment has a hollow cylinder 53, a first compressing part 51 provided with grooves 54 and equipped with two pins 57 and 58, a second compressing part 61 equipped with a central passage, and two permeable masses 52 and 62.
Assembly inside cylinder 53 proceeds as follows: when the permeable mass is disposed on pin 57 and permeable mass 62 on pin 58, compressing part 51 is made integral with cylinder 53, by one of the means described above, for example, and compressing part 61, which slides inside cylinder 53, xests on permeable mass 62, pin 58 passing inside a central passage 60 in compressing part 61.
cb/~ b A ~ ~ 8 7~
Under these circumstances, operation is as follows: the gas from the lighter (not shown) passes thxough passage 60 of com~
pressing part 61, passes through permeable mass 62 in the direction of the center, and exits through orifice 56.
Since compressing part 51 and cylinder 53 are immobile with respect to each other, it is obvious that the maximum flowrate of the entire device will be defined by the compression of permea~le mass 52.
However, it is possible to achieve a s:Lower rate of flow than this maximum flowrate by compressing permeable mass 62 with the aid of compressing part 61 by means of a classical device known of itseif and outside the scope o the invention.
In such a case, the device accoxding to the invention ~s used only to limit the maximum flame height of the lighter.
It is understood that, without departing from the scope of the ~nvention, ~he s~ructural or operational details can be modif~ed for the purpose of obtaining the same result.
