Abstract
A pressure regulator for a gas lighter which comprises, in a well of the lighter body, a porous membrane of constant natural porosity separating two chambers from one another to set the maximum flame height. A downstream chamber is connected to the burner outlet and serves for evaporation while upstream of the filter the wetting chamber communicates with the reservoir containing the fuel.
