PCT No. PCT/AT82/00004 Sec. 371 Date Nov. 19, 1982 Sec. 102(e) Date Nov. 19, 1982 PCT Filed Mar. 18, 1982 PCT Pub. No. WO82/03262 PCT Pub. Date Sep. 30, 1982.Liquid gas-operated lighter, particularly pocket lighter, comprising a closable valve at the opening of a valve bore which valve is in communication with a burner tip, a fuel tank and a non-adjustable control device for the flame height arranged between tank and valve bore. The control device is provided with a fuel-permeable proportioning disk of porous material which, on its side facing the fuel tank, is tightly pressed in its border region against a surface which is ring-shaped, preferably circular ring-shaped, by means of a structural component having a passage for the fuel. The annular surface (13) surrounds a recess (12a), which has an end face; the end face, together with the recess and the proportioning disk (14), forms a proportioning chamber which is in communication with the burner tip (4) exclusively through the valve bore (11). The end face (2') of the recess is provided totally or partially with a structure having recessed portions and possibly projections which maintain a constant connection between the proportioning chamber and the valve bore. When the valve is open, the proportioning disk of microporous film having microscopically small individual pores rests against the end face so as to close more and more pores as the pressure difference increases in dependence upon the temperature.
