Abstract
The invention relates to a gas flowrate adjustment and limitation device for a liquefied-gas lighter of the type having at least one compressible element traversed by the gas, and means of compressing this element to a greater or lesser degree depending on the desired flowrate. This device is characterized by having a permeable disk 12, the periphery of which is in contact with a coaxial permeable crown 7, by the gas passage in disk 12 and crown 7 being substantially radial, and by essentially the total surface area of each of the outer surfaces of said disk 12 and said crown 7 being in contact with some element of the device or lighter.
