Device for feeding an expanded gaseous fuel to a burner nozzle for instance of a lighter and lighter such as a cigarette lighter provided with such a device

A feeding device for supplying expanded fuel gas to a burner nozzle for instance of a lighter, comprising a sealed or fluid-tight casing divided by a resilient sealing element into a pair of chambers the first one of which communicates with said burner nozzle whereas the second one contains liquified gas under pressure, a valve member formed with a cylindrical bearing area portion inserted in sealing relationship through a cylindrical aperture formed in said sealing element and axially displaceable within said casing, a compressible porous member forming a pressure reducing means which is mounted in said second chamber onto said valve member and is connected through a passageway duct to said first chamber, wherein the improvement consists in that that end portion of said valve member which is located within said second chamber comprises a cup-shaped head in which is disposed said porous member which in a first axial position of said valve member within said casing is separated from said liquified gas under pressure by said head pressed in sealing engaging relationship against said resilient element and which in a second axial position of said valve member in which said head is spaced away from said sealing element, is fed with liquified gas under pressure and supplies said burner nozzle with expanded gas through the medium of said passageway duct and said first chamber.
