Gas distribution device. I [Prior Art] 10 Background of the Invention The tubular element that holds the gas distribution device in the wall of the gas reservoir is known to be constructed using a fitting that includes a threaded ring that is turned into the well and has a threaded upper portion As described in Figure 1 of document WO-A-01 / 18425. The advantage of this form of fitting is that it can be used in particular for an air reservoir made of amorphous 15 polymer. Among the mentioned non-crystalline polymers, they may be composed of SAN (styrene-acryl) and ABS (acryl-butadiene-styrene) and used as gas cylinders for gas lighters. It has several advantages. They are generally not expensive, easy to handle, and certain amorphous polymers such as SAN are transparent. It has the advantage of being able to see the height of the liquid-phase fuel remaining in the reservoir 20 cylinder. However, these amorphous polymers are quite brittle in the surrounding environment because their elongation at the elastic limit is small, typically less than 5%. Unlike press-fitting, using a threaded ring to assemble the tubular element does not actually create tensile stress on the wall of the well, and therefore avoids microcracks and allows gas to escape. 5 Η However, the threaded ring and the threaded part of the well require a relatively complicated mold, so the demolding operation is prolonged. In addition, 扃, .7 ^ When performing the combination of the lighter during the production process of Muyimu Automation, the operation of rotating the ring into the well is quite difficult and lengthy. These disadvantages mean that the manufacturing cost of mass production will increase significantly. Contents of the invention; 3 Summary of the invention The objective of the present invention is to reduce these disadvantages by specifically proposing a simplified installation of the tubular element in the well, while providing a good seal, reducing volume, completely safe to use and manufacturing the same One of the materials of the gas reservoir, such as an amorphous polymer, remains compatible. To this end, according to the present invention, the lighter is characterized in that the tubular element includes at least one crimping element that is elastic in the radial direction. When the tubular element is combined with the gas cylinder, the crimping element cooperates firmly with a fastener. In the well. With this device, the tubular element and the well can have a relatively smooth wall and be easier to shape, and the crimping element can be manufactured more simply than a thread. It is also relatively simple and fast to assemble the distribution device and the gas reservoir, because what is needed is to connect the tubular element to the well until the crimping element engages the fastener. In addition, the elasticity of the crimping element allows the crimping element to slide against the wall of the well without applying an excessive load and thus causing microcracking. In a preferred embodiment of the present invention, the method must also be one of the following or the other: 200404142 An annular seal, on the one hand, is disposed radially of one of the wall and the tubular element pointing radially outward. Between the outer edges and, on the other hand, between the wall pointing radially inward and one of the radial inner edges of the well to enhance the seal; 5 the tubular element has a first wheelbase along which The longitudinal axis measurement is between the radial outer edge and the contact point of the crimping element and the fastener, and the well has a second wheelbase between the radial inner edge and the crimping element and the Between the contact points of the fastener, the selection of the first and second distances is to apply a pre-pressure to the annular seal to ensure that the wall completely sealed in the well will not cause a significant tensile stress of 10; Around the mouth of the well on the inner wall of the gas storage cylinder; the crimping element includes an adjustment piece extending from the lower end of the tubular element in a longitudinal direction to a tip pointing longitudinally toward the upper end of the tubular element, and the adjusting piece is in the diameter Direction is elastic; 15 the tubular element in the package Contains a metal inner tube with a microporous film at its lower end to ensure a generally stable gas flow rate; the upper end of the tubular element includes a radial inner edge to define an opening, and an air outlet shaft of a valve passes through the opening. Moving along the axis of the tubular element, a pressure spring device causes the latter to remain closed between the radial inner edge and the valve; the gas cylinder is composed of a material selected from SAN and ABS; the tubular element is composed of a half Crystalline polymer composition. The drawings briefly explain the other features and advantages of the present invention in the following description by giving a non-limiting example 7 200404142. Refer to the attached drawing, where: Figure 1 is a vertical section of a lighter head The figure includes a gas distribution device according to a first embodiment of the present invention; FIG. 2 is a simplified diagram of a second embodiment of the gas distribution device according to FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the previous figures, the same reference symbols have been retained to indicate the same or similar elements. 0 The gas lighter i described in the figure Β1 contains a gas tank 2 purpose. 疋 It is used for fuels in which the pressure-containing part is in the liquid phase, such as trimethylmethane, for example. As shown in the implementation of the lighter, the gas cylinder 2 is composed of a slot 3 with a U-shaped cross section s which has a bottom not visible in the first figure, and an annular side wall extending up to an upper end 4. The upper end 4 is closed by an upper wall 5. In the example described, it is an additional component, which is read-fixed to the slot 3 by the peak example. One of the gas storage tanks 2 is composed of at least a rigid non-crystalline polymer. For example, the word ‘is selected from ABS (acrylic-butadiene-styrene) and styrene (propylene

These materials may be grafted in a known manner, and fused. And especially the advantage of these rigid amorphous polymers is that they are not expensive and easy to handle, besides, they have some, such as SAN, which are transparent 8 200404142 'and this advantage allows the user to check the liquid phase in the tank Fuel retention. The upper wall 5 of the gas reservoir has a well. It extends in the vertical axis and has the shape of a rotating cylinder. Yes-gas distribution device H) is installed in this well 6, which is activated by the operation device u, which is located on the -head 12 of the lighter, the head is placed on the top of the gas cylinder 2, and the head 12 also constitutes -wind Difficulty 13 and-the device support of the ignition device 14. The plutonium ignition device, as far as it is known, may include, for example, one of the spark wheels 15 and one of the round cups 18 disposed in the head 12 and a borrow: a plutonium yellow 17 bearing against the fire. Flower wheel of ocher 16. An additional cup is formed in the wall 5 above the gas cylinder for receiving the cup of the head. However, of course, other forms of ignition can be used, such as a piezoelectric device, for example. As described in the embodiment, the head 12 is supported on the wall 5 above the gas cylinder by the head bolt 20 of the head, and the pillar and the complementary pillar 21 are combined with each other to shape the wall 5 above the gas cylinder. The distribution device 10 includes a tubular element 22 disposed in the well 6. The tubular member 22 may include an inner tube made of metal, and the tubular member 22 is preferably composed of a semi-crystalline polymer such as POM (polyacetal) or nylon-6,6. The 20th-grade semi-crystalline polymer has great strength and therefore the tube 23 can be press-fitted with respect to the tube-like member 22 to achieve sealing and fixing. Arranged in a lower portion 24 of one of the tubes 23 is a microporous film 25, which ensures a stable gas flow rate. The film may consist of a uniaxially stretched polypropylene film and have elongated holes, as described in US Pat. No. 4,496,309, 9 200404142. The film 25 is placed against one of the inner shoulders 23a of the tube 23, which defines an orifice 26 by a rigid mount 27 to allow the gas to pass through. The ring 27 itself is maintained at the lower portion by clamping the lower portion of the official tube 23. According to the present invention, the tubular element 22 includes two crimping elements (28, 29) 5, which are designed to cooperate with a fastener, and when the tubular element is assembled to the wall 5 above the gas reservoir 2, it is firmly fixed in the well. The two crimping elements (28, 29) are radially elastic in relation to one of the longitudinal directions 2, which allows them to deform inwardly to limit the amount of load applied to the ventilator wall. The tubular element 22 and the upper wall 5 of the gas cylinder 2 do not have any threads, and 10 can be obtained at a high production rate by using molding. Beyond that, assembly is particularly easy because all that is required is to engage the tubular element 22 to the well until the crimping element (28, 29) engages the fastener (30). It should be emphasized that both the well 6 and the tubular element 22 have smooth walls, which contact each other for a considerable length, which makes it possible to obtain a reliable seal between the gas cylinder 2 and the 1S gas distribution device 10 may. However, if a gas reservoir is composed of SAN or ABS, the diameter of the tubular element 22 must not exceed the diameter of the well 6; otherwise, the wall of the well may be slightly cracked. To make this combination possible with a pre-filled gas cylinder, the well 6 contains a diaphragm which is broken when the tubular element 22 is embedded in the well. 20 To enhance sealing, an annular seal 31 is placed between the wall pointing radially outward and a radial outer edge 32 of the tubular element 22 on the one hand, and on the other hand, Between the wall and a radially inner edge 33 of the well 6. The official element has a first wheelbase Hl, measured along its longitudinal axis 2 between

The selection of the first and second distances is to apply a pre-pressure to the annular seal to ensure that the wall completely sealed in the well does not cause significant tensile stress; advantageously, the first and second distances The selection of (H1, H2) is to apply a pre-pressure to the annular seal 31. The pressure needs to be high enough to ensure complete sealing, however, it will not be too high. The reason for this is that if the seal is pressed too much, there is a risk, and tensile stresses are generated, causing microcracks in the wall of the well. It is emphasized that, unlike the assembly of the conventional technique using a threaded ring, it can be tightened to a greater or lesser degree, reducing the configuration of the present invention, allowing the pressure exerted on the seal to be accurately established. The crimping element (28, 29) is preferably disposed on a lower portion 22a of the tubular element. With this arrangement, they cannot be accessed and the combination of the tubular element and the upper wall of the gas cylinder cannot be disassembled, so This promotes the King of Lighter's actually 'using the skill of the art § 1-users with bad intentions can turn the threaded ring' on, causing fuel to leak out. In the described embodiment, the fastener 30 is formed by surrounding the well 6 in the inner face 5a of the upper wall 5 of the gas cylinder. Each crimping element (28, 29) includes an adjusting piece 35 extending from the lower end of the tubular element 22 in the longitudinal direction B to a central end that points radially outwards and has a-pointing longitudinally toward the upper end of the tubular element 22 Lateral surface 37. The adjusting piece 35 has radial elasticity. When the tubular element is roped in the material, the 200404142 tip 36 is allowed to lean inward, and when the combined position is reached, it returns to its position, so that the lateral surface 37 of the tip 36 The support leans against the fastener 30. A free space is provided between the inner surface of the adjusting piece 35 and the tube 23 so that the tip 36 can lean inward. 5 As shown more clearly in Figure 2, the tubular element includes two crimping elements (28, 29) ′ The lateral surface of the adjusting piece 35 constitutes two completely opposite arcs. However, it is of course possible to increase or decrease the number of such crimping elements to a single crimping element. As can be seen in Fig. 1, the distribution device 10 also includes a valve 40, which 10 includes a gas outlet shaft 41 opening close to the ignition device 14. The shaft 41 is movable along the second axis of the tubular member and has a shutter 42 made of a piezoelectric material at the lower portion thereof, which is designed to close the gas passage opening 26. A slit 43 formed in the shaft near the sowing gate 42 provides communication within the tube 23. The operating device 11 includes a fork 45 that is rocked 15 according to a wheel shaft firmly on the head 12, a first end 46 of the fork 45 and a lower shoulder 47 and an upper shoulder formed on the upper end of the shaft 41 exposed from the tube 23. 48 cooperation. When the user presses the second end 49 of the fork 45, the shaft 41 is raised and the valve 40 is opened. To keep the valve 40 closed in the rest position, a pressure spring 50 is placed between the lower side of the second end 49 of the fork and the bottom 51 of the well formed on the wall 5 20 of the gas reservoir. According to the description in Fig. 2 an alternative form of the distribution device 10, the upper end 52 comprises a radially inner circular edge 53 which defines an opening 54 passing through the air shaft. A pressure spring 55 is placed between the rounded edge and the lower shoulder 0 to keep the valve closed. As before, what is needed to open the valve is to shake the 12 200404142 the fork (not described in the second figure) to cause the first end of the fork to press against the upper shoulder 48 of the shaft 41 and lift the shaft to squeeze the Spring ring 55. It is emphasized that the spring 50 which is placed under the second end 49 of the fork is no longer needed. In this embodiment, the distribution device 10 forms a complete combination, including 5 a device for adjusting the gas flow rate, the device consisting of the microporous film 25 and a valve 40 for controlling the flow rate. The valve has the advantage of closing naturally, so when the tubular element 22 is assembled in the well 6, gas leaks are escaped via the microporous membrane before breaking through a diaphragm sitting in the well and before the valve has been assembled. In addition to reducing the gas loss, this device makes it possible to simplify the 10 device to supplement gas on the production line.
