PURPOSE:To make it possible to control the flow quantity of the vaporized fuel and re-inject a fuel for use in a market sold gas lighter by changing the opening area of a porous substance. CONSTITUTION:As the porous substance 11, a substance which is formed by a sintered metal or ceramics, and has a density causing a pressure loss for reducing the flow quantity of a compressed fluid. The density of the porous substance is set in accordance with the heat generation quantity required for each portable type catalyst burner. The control valve 15 is formed by rubber having a shape of a sphere R, for example. When the clearance X between the porous substance 11 and the valve device 13 is narrowed by the movement of the thermal responding element 41, the opening area of the porous substance 11 reduces. Accordingly, it is possible to arbitrarily change the control characteristic by the selection of the density of the porous substance 11 and the shape of the control valve 15. |
