Definitions

  • This invention relates to gas lighters and more particular- ly to a device for limiting the gas flow in a discharge val- ve of gas lighters without flame adjustment and a method of calibrating such a device.
  • the gas lighters are or not provided with a flame height adjusting means to be operated by the user, they are generally provided with at least a filter limiting the flame height to a lower value than the maximum height permissible for security purposes.
  • This filter is formed of a porous material such as fibers or foam and means are provided to adjust in the mounting operation the compression of such a filter according to the maximum desirable flow.
  • the flame height is, however, predetermined according to a standard gas pressure at a standard reference temperature.
  • This invention intends to obviate the above mentioned disadvantages of the prior art gas lighters, without flame adjustment, by providing a lighter of this type in which the flame height is kept nearly fixed with changes in the temperature and consequently in the gas pressure in the tank, by means of an automatic compensation for the delivered gas flow, and which is at the same time of a low manufacturing cost.
  • a device for limiting the gas flow in a discharge valve for gas lighters without flame adjustment and for automatically compensating for gas pressure differences in dependence of the temperature of the type comprising a porous filter compressed to a predetermined extent, characterized in that the filter is compressed between two elements of different material having different linear thermal expansion coefficients, anchored to each other at one end and free to expand indepen- I dently of each other, due to temperature changes, at the ! other end.
  • the compression on the filter also changes with changes in the temperature and causes the gas flow which flows through the filter to change correspondingly and, as a result, tends to prevent changes in the flame height.
  • the linear length of the expansion elements is determined in dependence of their expansion coefficients with respect to the change of the porosity characteristics of the filter at different compression values in such a manner as to obtain a desired and nearly invariable value of the flame height whatever the ambient temperature may be.
  • the invention comprises also a method of calibrating the above mentioned gas flow limitation device, characterized in that the calibrating compression of the filter is carried out by means of an axial deformation of the jacket or by other mechanical pressure means until the gas flow is reduced to the predetermined value which is such as to limit the maximum flame height to the desired value.
  • the deformation of the jacket or the action of the mechanical pressure means is carried out at a standard reference temperature and the calibration value of the compression of the filter is controlled during the compression by means of a suitable apparatus which measures the flow of a fluid flowing through the filter.
  • the measuring apparatus can suitably consist of a compressed air flowmeter or any other means adapted to determine the calibration in dependence of a predetermined flame height, which flowmeter is associated to the control of the deformation equipment of the jacket so as to cause a stop in the deformation at the time the flow calibration reaches the predetermined value.
  • the porous filter 1 for regulating the gas flow is contained in a variable volume chamber 2 suitably formed by a central cylindrical body 3 made of a material having a high linear expansion coefficient and covered outside by a jacket 4 made of a material having a low linear expansion coefficient.
  • a nozzle 6 and a washer 7 are interposed which are anyway without influence on the operation of the compensating device.
  • the jacket 4 is firmly anchored to the central cylindrical body 3 by means of a mechanical hooking 8 so as to cause an effective volumetric change of the chamber 2 at any minimum mutual dimensional change in the elements 3 and 4 with changes in the temperature.
  • the calibrating compression of the filter 1 is carried out by means of an axial deformation of the edges 9 and 10 of the jacket 4 at a standard reference temperature.
  • a porous dipping element 11 supplies gas in a liquid phase to the filter 1 by conveying it by capillarity from the tank 12.
  • the complete device is mounted and calibrated outside the lighter and can be mounted in the tank housing 15 f.e. by forcing it in a seat 14 by means of a suitable mechanical interference so as to prevent the flow of the gas outside the jacket 4.
  • This flow can be prevented also by means of a gasket 16 or by interposing a deformable and re.siliant material of a different type.
  • the limitation of the fixed flame height is determined by the compression of the filter 1 carried out originally by an axial deformation of the edges 9 and 10 of the jacket 4 at a standard reference temperature, by simultaneously measuring the flow of a fluid through the filter. This deformation operation of the edges 9 and 10 is stopped when the fluid flow reaches the desired value.
  • a suitable length sizing of the cylindrical body 3 and the jacket 4 determines a suitable higher compression of the filter 1 with increasing temperature and its suitable decompression with decreasing temperature; since the gas pressure increases and decreases respectively, the output flow is kept nearly constant and the flame height undergoes practically no appreciable changes.
  • Fig. 2 there is shown an alternative embodiment of the device according to the invention in which, however, the compression of the filter 1 is carried out originally by screwing the nozzle 6 in the jacket 4 by means of the thread 17 suitably locked permanently against unscrewing after c a - libration.
