Pressure regulator for gas lighter

A pressure regulator for a gas lighter containing a reservoir of a gasifiable liquid fuel, said pressure regulator comprising a porous membrane of constant natural porosity and good wettability for hydrocarbons constituting a filter for controlling the maximum flame height of said lighter, means defining on one side of said filter a wetting chamber communicating with said reservoir, means defining on the other side of said filter an evaporation chamber communicating with a burner outlet, said filter having porosity characteristics determined at the time of its manufacture to establish a maximum height for said flame, at least one fiber layer disposed along a side of said membrane, said membrane being composed of a material selected from the group which consists of polyethylene and polypropylene.
