Definitions

  • the present invention relates to an improved gas lighter of the flame and spark type.
  • gas lighters for domestic use are available which are capable of producing the spark required to ignite town gas, methane, liquid gas and the like, as well as gas lighters which are capable of producing a flame, for example for the ignition of chimneys, barbecues, and the like.
  • Such gas lighters essentially consist of a handle which includes the piezoelectric mechanism for the production of the spark and the fuel tank, as well as systems for the delivery and the orientation of the spark and of the flame towards the outer environment.
  • the handle of such devices is hollow and accommodates in its interior a tank and a gas delivery system.
  • the delivery valve is provided with a knurled wheel mechanism which allows to perform the manual control of said valve and therefore also of the flame which forms on the tip of the delivery pipe.
  • the aim proposed by the invention is indeed to overcome the limitations and the disadvantages of conventional solutions by providing a gas lighter wherein the formation of the flame is not affected by the abovementioned technical environmental factors.
  • a particular object of the invention is to provide a gas lighter wherein it is possible to provide a tank having such a structure as to allow the differentiation of the production of gas lighters without thereby having to intervene with particular modifications on said tank.
  • Still another object of the present invention is to provide a gas lighter which is extremely simple from a structural point of view and which furthermore is considerably advantageous from a functional point of view.
  • an improved gas lighter of the flame and spark type characterized in that it comprises elastically deformable means, arranged upstream with respect to the delivery value of the tank in the direction of the flow of fuel, said means being adapted to define at least one section with variable opening size for the delivery of said fuel.
  • the gas lighter generally indicated by the reference numeral 1, comprises a tank wherefrom there extends a deliver pipe 2.
  • the tank is made of two partially hollow parts 3 and 4 which are mutually joined so as to define an inner tank for the fuel, indicated by 5, and a conduit 6, arranged laterally with respect to the tank 5, for the delivery of the gas.
  • the loading of the liquid fuel into the tank 5 is performed through a valve 7; a through hole 8 provides a connection of liquid between said tank 5 and the conduit 6.
  • the conduit 6 is furthermore provided, on its side facing the fuel discharge section, with a widened vaporization chamber 9 wherein the change of state of the fuel from liquid to gas occurs.
  • the discharge section of the chamber 9 is provided with a delivery valve 10, adjustable by means of the knurled knob 11, which valve 10 is provided with a nozzle 12 for the outflow of the gas towards the pipe 2.
  • valve 10 The complete opening and closure of the valve 10 can be controlled by a cam 13-bracket 14 assembly, which in turn is controlled by means of a manual operating button 15.
  • the reference numeral 16 generally indicates the piezoelectric mechanism for the production of the spark, the electrodes whereof reach the free end of the pipe in which the flame is also produced.
  • the degree of compression of the small disk 17, which determines the variation of the size of the opening for the passage of the combustible gas, is controlled by a stem composed of two parts, 18 and 19, respectively accommodated in the liquid fuel delivery conduit 6 and in the vaporization chamber 9.
  • the stem 18/19 is arranged in the body of the gas lighter device so as to be able to perform a translatory motion within the path of the fuel; said translatory motion, on one hand, can be controlled by means of a threaded pin coupling 20 and, on the other hand, causes the greater or smaller compression of the small disc of spongy material 17.
  • the relative dimensions of the diameter of the stem 18/19 with respect to that of said path 6 and 9 are such as to leave, around said stem, an interspace which is sufficient to allow the passage of the fuel from the tank 5 towards the disc 17.
  • the end of the stem part 18 directed towards the threaded-pin adjustment mechanism 20 is provided with an o-ring 21 adapted to provide a seal for the fuel circulating in the conduit 6.
  • Another important aspect of the invention furthermore resides in the fact that the particular scruciture adopted in the tank design allows, in a way, to standardize gas lighter production processes, thus allowing to reduce the production costs in general, as well as that of the finished product.
  • the materials employed, as well as the dimensions and the contingent shapes may be any according to the requirements.
