Definitions

  • the invention relates to a lighter operated with liquefied petroleum gas, in particular a pocket lighter, which comprises a burner head, a fuel tank and an adjustable measuring device for the flame height which is arranged in between and which is provided with a fuel-permeable metering disc made of microporous film, which on its side facing the fuel tank by means of a a passage opening for the fuel-containing clamping disk is tightly clamped in its edge region and with its side facing the burner head bears against a component having a gas-permeable layer.
  • pocket lighters especially those without an adjustable flame regulator, it is due to production variations that a major problem is to keep the flame height constant, in particular to achieve a uniform flame detection.
  • the amount of gas flowing out and thus the flame height changes with the temperature.
  • a temperature change of approximately 10 ° C will result in a change in flame height of approximately 10 mm, for example using isobutane gas at a flame height of 25 mm will consume approximately 1 milligram of fuel per second .
  • the usual gas lighters are largely equipped with porous bodies as throttling elements for the fuel. These throttle elements are also used to regulate the flame height. To the extent that it is a body made of fibers, the fuel flow can be reduced by appropriate compression of the body are regulated, each. the more the body is pressed together, the lower the flow rate. If the throttle bodies are made of solid, porous materials, such as sintered material, the flow rate is regulated by covering the surface of the sections of the body which are exposed to fuel by elastically deformable elements. However, it is also known to guide the fuel through a narrow bore of a rubber-elastic element to the burner head and to regulate the flow rate by radially deforming the rubber body by means of axial pressure, with the small flow bore being constricted.
  • the compression is set in the manufacture of the lighters so that the flame has a permissible height. It is up to the user to set a different flame height.
  • the invention is based on the knowledge contradicting the prevailing doctrine that a calm flame with a limited height can be achieved even with a longer burning time if fuel in gaseous form is present on the upstream side of the membrane.
  • the practical implementation is difficult because the uncontrolled position of the lighter always brings liquid fuel to the membrane and wets it between its use. Care must therefore be taken to ensure that when the lighter is raised into its position of use, the liquid fuel quickly runs away from the membrane into the container and only an unavoidable amount of liquid fuel remains in the area of the membrane.
  • the basic idea of the invention is therefore to design the size and shape of the components of the dimensioning device facing the interior of the fuel tank in such a way that as little liquid fuel as possible is retained by surface forces.
  • this has a clamping disk which presses the dosing disk, which is also made of microporous film, tightly together in its edge area, so that only the area kept free from the pressing is available for the passage of the fuel.
  • a measuring device meets the conditions for achieving the object of the invention when, according to the invention, the clamping disk forms the end of the lower end of the measuring device, and this end in the upright use position of the lighter is always at a distance above the liquid phase of the liquid gas and the space between the Measuring device and the liquid level is free of components.
  • the design of the measuring device according to the invention results in a very uniform burning flame and, moreover, the lighters leaving the manufacturing facility show little variation in the flame height. Since the lighters have no regulating device for adjusting the flame height, it is of particular importance that the flame height resulting from the manufacture of the lighters is as uniform as possible and corresponds to the normal flame height of 25 mm at 298 K.
  • Surfaces and spaces of the components of the dimensioning device and their housing facing the fuel container have a size and a volume at which the amount of liquid fuel adhering to these components when the lighter is pivoted into the normal, upright position of use as a result of surface forces, is less than the amount of fuel consumed by the normal flame within three seconds, preferably in less than one second.
  • the surfaces, especially the clamping disc can be provided with a coating that repels the liquid fuel.
  • Fig. 1 shows a partial section through a lighter according to the invention, which is equipped with an unadjustable measuring device for keeping the flame height constant. In order to increase clarity, all those parts which are unnecessary for the explanation of the invention are not shown.
  • a valve body 2 is pressed in a gas-tight manner into the upper wall of a liquid gas container 1 and receives a displaceable detector tube 3 in a bore on the side facing away from the container.
  • the burner tube 3 has at its upper end a burner head 4, under which an operating lever 5 engages. From the outlet 6, a bore 8 passing through the burner tube 3 leads to a transverse bore 7.
  • a sealing disk 9 is arranged, which cooperates with a valve seat 10 of the valve body 2.
  • the actuating lever 5 presses the detector tube 3 down against the valve seat 10 under the influence of a spring (not shown) and thus closes a valve bore 11.
  • a blind hole-like depression 12 is provided in the valve body 2, on the end wall of which a nonwoven layer 13 is applied, which forms the component having the gas-permeable layer.
  • a metering disk 14 is arranged below the nonwoven fabric layer 13 and is pressed against the nonwoven fabric layer by a clamping disk 15, as a result of which the clamping surface is largely gas-tight.
  • a cavity 16 is arranged in the clamping disk 15 and is connected to the container 1 via an opening 17.
  • the recess 12, the nonwoven fabric pushes 13, the metering disc 14, the clamping disc 15 and the cavity 16 form the dimensioning device according to the invention.
  • the metering disc 14 consists of a microporous plastic film which is permeable to the liquid and the gaseous phase of the liquid gas in the direction of the surface normal.
  • a microporous uniaxially stretched polypropylene film with a thickness between 10 and 100 ⁇ m, preferably between 15 and 30 ⁇ m, and slot-shaped pores oriented in the direction of stretching is particularly suitable for this.
  • Such a product is among others currently from Celanese Corp., USA, under the brand name.
  • the coefficient of thermal expansion of the metering disc 14 is preferably close to or equal to that of the clamping disc 15.
  • the fiber fleece layer 13 has a thickness of 20 to 200 ⁇ m, preferably 20 to 50 ⁇ c. Textile laminates made from non-woven polypropylene fibers, which are produced either by the “meltair-blow” process or the “spinbond” process, are particularly suitable for this purpose. In particular, the "melt-air-blow” process delivers very uniform laminates.
  • a particular advantage of the nonwoven layer 13 is that mechanical instabilities of the metering disc 14, such as periodic flutter, are alleviated.
  • the metering disc 14 and the nonwoven fabric layer 13 are clamped in the recess 12 such that the clamping surface forms a gas-tight seal.
  • the clamping disc 15 is fixed by crimping the edge of the recess 12. It is advantageous to produce the valve body 2 from a metallic material, preferably from automatic brass, since the high pressure resistance of such materials enables a reliably tight closure.
  • the cavity 16 is incorporated in the clamping disk 15 on its side facing the metering disk 14. However, it can also be formed in a different way and also lie on the side of the metering disc 14 facing away from the container 1.
  • the cross section of the cavity 16 perpendicular to the axis of the metering disc 14 determines the size, position and shape of the surface of the metering disc 14 which can be exposed to the fuel. In general, this surface 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 thickness of the clamping disc 15 is less than the hydraulic diameter, preferably less than half the hydraulic diameter,
  • the purpose of the cavity 16 is to keep a defined cross section of the metering disc 14 free for gas to pass through.
  • the area of the metering disc 14 which can be acted upon by the fuel is matched to its gas permeability in such a way that a desired amount of gas is let through in the direction of the burner head.
  • the depth of the cavity must be at least so large that, due to the clamping force exerted by the clamping disc 15 on the metering disc 14 and the nonwoven layer 13, the gas permeability of the nonwoven layer 13 parallel to the contact surface is not impaired.
  • the metering disc 14 Due to its small thickness, the metering disc 14 is extremely flexible, so that it can escape into an open space even at a low pressure, such as that which the nonwoven layer 13 can transmit without any noteworthy compression or as prevails as the saturation vapor pressure in the container 1. Due to the clamping force exerted by the clamping disc 15, the nonwoven fabric layer 13 is compressed in the region of the clamping surface and the metering disc 14 is pressed into it, so that the clamping region becomes gas-impermeable. In the region of the cavity 16, the nonwoven layer 13 remains undensified.
  • the cavity 16 is on the side of the metering disc 14 facing or facing away from the container, since in any case it is possible to escape into the cavity 16 without any appreciable compression of the nonwoven layer 13.
  • a surface corresponding to the cross section of the cavity 16 is reliably released for the gas passage, as long as only the nonwoven layer 13 or another layer corresponding to its effect is arranged at least in the region of the cavity 16 and lies on the side of the metering disc 14 facing away from the container 1.
  • the metering disc 14 and the gas-permeable nonwoven layer 13 are preferably in or directly below the level of the container ceiling 20.
  • the clamping disc 15 can have a diameter of 3 mm and the cavity 16 can have a diameter of 1.8 mm and a depth of 0.12 mm in order to produce a flame height of 25 mm (standard flame) at an ambient temperature of 298 K , which consumes approximately 1 milligram of fuel per second.
  • the flame height can be directly influenced by changing the cavity cross section.
  • a calm and uniform burning of the flame in the normal upright operating position is achieved according to the invention by an arrangement of the dimensioning device which reduces or excludes as far as possible a direct contact of the metering disc 14 with the liquid phase of the container filling. If 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 acted upon by the gaseous fuel and separated from the liquid level 21 of the fuel.
  • the thickness of the clamping disc 15 is not greater than the hydraulic diameter of the cavity 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 is possibly retained, based on the cross section of the metering disc available for gas passage, is so small that it can be eg in about 1 second, runs off, evaporates or is burned. If there is any spontaneous, bubble-forming on the side of the metering disc 14 facing the container 1 When the liquid fuel boils, the amount available for it evaporates 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 uniformly burning flame is achieved.
  • the effect according to the invention can easily be enhanced by various measures.
  • the most complete possible outflow of the liquid phase when the burner is raised is favored if the surface of the clamping disc 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 opening 17 so small that capillary forces promote the outflow of the fuel from the cavity 16. If the clamping disk 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 lies approximately in the plane of the liquid gas tank cover 20 of the liquid gas tank 1 .
  • FIGS. 2-8 each represent a cross section through the measuring device. All reference numbers are chosen in accordance with FIG. 1.
  • Fig. 2 shows an embodiment in which the cavity 16 is formed by a recess on the end face of the recess 12.
  • the cavity 16 can therefore be manufactured in one operation with the production of the recess 12 in the valve body 2, which is possible with high accuracy.
  • the design of the clamping disk 15 shown results in a symmetrical deformation of the metering disk 14 and the nonwoven fabric 13.
  • the cabbage chamber 16 is arranged on the side of the metering disc 14 facing away from the container 1, but is limited on the circumference by a spacer ring 18 which, like the metering disc 14 and the nonwoven layer 13, by Clamping disc 15 is clamped gas-tight.
  • the spacer ring 18 consists of a plastic material of high rigidity, pressure resistance, heat resistance and 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 approximately the same thermal expansion as brass, so that no thermal stresses interfere with the function of the device according to the invention when the valve body 2 is made from automatic brass.
  • the spacer ring 18 can simply be punched out of commercially available foils, which enables very cheap production.
  • the plastic material of the spacer ring 18 also promotes the seal in the clamping surface.
  • the opening 17 is small in relation to the hydraulic diameter, which avoids the retention of large amounts of liquid fuel when the lighter is raised.
  • the embodiment according to FIG. 4 essentially corresponds to that according to FIG. 2, but an intermediate ring 19 is arranged between the metering disc 14 and the clamping disc 15, which is made of a plastic material of the type advantageously used for the spacer ring 18, FIG. 3 becomes. This on the one hand favors the sealing on the clamping surface, but on the other hand damages to the metering disc 14 are avoided during assembly if, for example, a measuring tube is placed to check the gas flow rate.
  • FIG. 5 shows an embodiment in which a nonwoven layer 13 is arranged only in the region of the cavity 16 located in the valve body 2.
  • an intermediate ring 19 is arranged between the clamping disc 15 and the metering disc 14, as in FIG. 4.
  • the arrangement of the fiber fleece layer 13 exclusively in the region of the cavity 16 does not have any functional disadvantages, but allows material savings and particularly simple assembly.
  • FIG. 6 shows an embodiment in which the cavity 16 is located in the clamping disc 15 and merges seamlessly into the opening 17.
  • This design aims to avoid capillary effects with a wettable surface of the clamping disc 15.
  • the opening 17 has a relatively large diameter, which favors the outflow of the liquid phase with a wettable surface of the clamping disc 15, since a capillary effect is avoided.
  • the opening 17 can also be widened in a funnel shape towards the container 1.
  • FIG. 7 shows an embodiment which essentially corresponds to that in FIG. 1, but has an intermediate layer 19 ′ on the burner head side of the nonwoven fabric layer 13, which is made of a plastic material which in the embodiment of the invention according to FIG. 3 for the spacer ring 18 is used advantageously.
  • the manufacturing costs of the lighter according to the invention are significantly reduced by the fact that no voluminous components are necessary that cause high material costs.
  • the costs for the mechanical processing of the components are also low, since no large amounts of material have to be removed and no processing with high requirements in places that are difficult to access, for example in deep blind holes. Since the required small parts are all arranged in very shallow recesses, their installation can also be done easily and with relatively simple devices.
  • the small dimensions of the components also prevent the occurrence of larger thermal expansions or thermal stresses which e.g. Reduce the necessary clamping forces irreversibly through longer storage or transport at a higher temperature.
  • the usually occurring dimensional deviations which can cause considerable differences in flame height within a production series, can be significantly reduced in a rational manner with the device according to the invention.
  • the simplicity of the required components enables high quality consistency.
  • the arrangement of all small parts in easily accessible shallow recesses also considerably reduces the likelihood of assembly errors.
  • it also enables the gas permeability of the metering disk 14 to be checked in a simple manner and to compensate for the scatterings of the gas passage quantities that have been determined. This can be done in the following way, for example. After the fiber fleece layer 13 and the metering disc 14 have been inserted into the recess 12, a measuring tube with a precisely determined inner diameter, which is preferably larger than the hydraulic diameter, is pressed tightly.
  • the gas flow rate is measured and compared with a specified setpoint.
  • either the metering disk 14 can be blown out and replaced by a new one, or the diameter of the cavity 16 is adapted accordingly. This can be done, for example, by selecting and installing a suitable variant from the magazine components with graduated diameters of the cavity, such as clamping disks 15 or spacer rings 18.
  • a suitable variant from the magazine components with graduated diameters of the cavity, such as clamping disks 15 or spacer rings 18.
  • Such a control and selection device can be easily installed in a conventional automated production line. In the known embodiment, measures to control and compensate for flow scattering are considerably more complex or cannot be carried out at all.
  • 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.
  • a microporous, uniaxially stretched polypropylene film preferably made of "Celgard 2500"
  • material for the metering disc 14 in particular in combination with a nonwoven layer 13, of non-woven polypropylene fibers gives the inventive device a very high resistance to aging in terms of constancy the flame characteristic with itself.
  • the uniaxially stretched polypropylene film is deformable in the undrawn direction, which could inadvertently affect the flow rate. It is therefore advantageous to open the valve bore 11 to be very small, for example 0.1 to 0.4 mm, so that the metering disc and the fleece layer cannot be pressed in by the gas pressure, and to limit the depth of the cavity 1 if it is arranged on the burner head side of the metering disc, in order to prevent irreversible Avoid deformation of the metering disc under the influence of the gas pressure acting on it.
  • any component can be used which has a gas-permeable layer along the contact surface with the metering disc 14. This is also created, for example, by the valve body 2 on the end face 2 'of the blind hole-like depression 12 at least in the region of the cavity 16 in a suitable manner, e.g. is roughened by sandblasting.
  • the filling quantity of the liquid gas When producing lighters, e.g. pocket lighters that cannot be refilled, the filling quantity of the liquid gas must be limited to approximately 80% of the volume of the fuel tank, the ambient temperature during the filling process being approximately 20 ° to 25 ° C. This limitation is necessary for safety reasons, since the liquid fuel when stored later or when the lighters are used at much higher temperatures, e.g. 60oC, could cause the container to explode.
