ABSTRACT:
A fuel burning lighter having an adjustable flame height comprising burner means, a supply of liquified gaseous fuel, valve means positioned between the fuel supply and the burner means, and a film having a plurality of micropores oriented substantially perpendicular to its surface. The film is positioned between the valve means and the fuel supply in such a manner so that all fuel flowing to the burner means must pass through the micropores. The lighter also includes means for conducting fuel passing through the film through the valve means to the burner means, and control means to selectively increase or decrease the passage of fuel through the film to the burner means so as to provide a flame of desired height.
