Definitions

  • an adjustment member which is disposed at the bottom of the gas tank.
  • the adjustment member is sealed against the ambient air by means of O-rings and, in turn, houses the filling valve. It is well known that, during the filling of the lighter with a liquefied gas, a strong local cooling takes place. This is due to the evaporation of the liquefied gas. Accordingly, the adjustment member, with its filling valve and the valve tube are rapidly cooled. This causes a shrinkage of the diameter of the valve tube as well as a shortening of the entire valve tube.
  • valve tube Since the valve tube is secured at both ends within the walls of the gas tank, large temperature differences are experienced at these places so that fine cracks may form at the portions of the tube secured to the tank walls. This, in turn, may cause escape of the liquefied gas which is at a pressure above atmospheric so that the lighter is no longer capable of operating.
  • the burner valve with its valve tube, is difficult to remove and replace.
  • the lighter needs to be repaired, it is usually necessary to replace the entire gas tank with both burner and filling valves.
  • an object of the present invention to provide a liquefied gas lighter having a combination burner and filling valve which obviates the drawbacks of the prior art lighters as discussed.
  • Another object of the present invention is to provide a liquefied gas lighter having a burner valve which combines the advantages of being capable of adjustment at the bottom of the gas tank with simplified assembly and repair of the valve mechanism.
  • a further object of the present invention is to provide a v lighter of the type referred to which avoids the possibility of the gas tank leaking due to the large temperature changes experienced when the lighter is filled with liquefied gas.
  • a liquefied gas lighter in accordance with the present invention includes a burner valve which is operatively connected to the free end of an interconnecting control member which forms the throttle device for the gas flowing to the burner.
  • This free end of the control member and the rotatable adjustment member are each inserted into a separate tube.
  • Each of the two tubes separately extend through the walls of the gas tank, each tube being sealed from the ambient air.
  • valve construction of the invention was not made obvious to the man skilled in the art. This is made evident by the fact that the prior art lighter construction previously described has been manufactured for a long period of time. The same construction has been used for the burner valves of a lighter without a filling valve disposed within the flame adjustment mechanism arranged in the tank bottom. Even in this case, a valve tube extending from one end of the tank to the other has been provided; that is, from the burner valve to the bottom of the tank where the adjustment mechanism is disposed.
  • the interconnecting control member is guided or mounted within the adjustment member on the one hand, and the valve body on the other hand.
  • the burner valve advantageously is provided with a tubelike extension which extends beyond the throttle device and partially past the control member. Accordingly, the interconnecting control member may be rotated within the tubelike extension to tension the fleece of the throttle device by means of a screw thread.
  • FIGURE is a sectional view, parts being broken away, of a gas tank of a liquefied gas lighter including a combination burner and filling valve according to the invention, capable of adjustment of the flame from the bottom of the gas tank.
  • the gas tank 1 includes an upper portion 11 and a bottom portion 12, the two portions being, for example, adhesively secured together.
  • the upper portion 11 is provided with a cylindrical opening 111 within which is secured a valve tube 2 having an outer flange.
  • the valve tube 2 maybe secured by a suitable adhesive or by a screw thread, as shown. In case the valve tube 2 is threaded, the tube is sealed by means of a seal 3 to the upper portion 11 of the tank.
  • a burner valve 4 is disposed in the tube 2.
  • the portion of the burner valve 4 within the tank is provided with a throttle device 5 which may consist of two fleece discs 51 and 52.
  • a throttle device 5 which may consist of two fleece discs 51 and 52.
  • the two discs 51 and 52 are disposed within a tubelike extension 41 of the valve 4. They bear against a support 42 of the valve and against an interconnecting control member 6 which may be tensioned within the tubelike extension by means of a screw thread 411 against the support 42.
  • the bottom portion 12 of the gas tank is similarly provided with a bore or cylindrical opening 121 within which is disposed a tube 7 having an outer flange.
  • the tube 7 is secured to the tank and sealed therewith. It receives an adjustment member 8 which houses the filling valve 9.
  • the adjustment member 8 is rotatably mounted and sealed to the wall of the tank.
  • the adjustment member 8 is secured against axial movement by a safety disc 10. It is provided with a tubelike extension 81 extending into the tank for receiving the interconnecting control member 6.
  • the filling valve 9 is tensioned against the interconnecting control member 6 by means of a spring 13.
  • Rotation of the adjustment member 8 for increasing or decreasing the height of the flame is transmitted by means of a pin 61 slidably disposed in two slits 82 of the tube 81 to the interconnecting control member 6.
  • a pin 61 slidably disposed in two slits 82 of the tube 81 to the interconnecting control member 6.
  • a particular advantage of the invention consists in that the adjustment mechanism at the bottom of the tank, as well as the burner valve at the top of the tank, may be separately replaced. This was not possible with prior art lighters because the entire valve combination had to be fastened to the tank as a single unit so as to obtain a gastight connection. Also, it is no longer necessary to provide an exact alignment of the apertures in the upper and lower portion of the tank for receiving the valve combination.
  • a liquefied gas lighter comprising:
  • a tank for the liquefied gas having an upper and a lower portion
