<p>PROBLEM TO BE SOLVED: To detect the reduction of a gas amount in combustible fluid for a gas-fired gas generator in which gas is fired by putting a current-heated ignition filament in direct contact with combustible fluid in a storage container with one combustion chamber or a plurality of combustion chambers communicated with one another. SOLUTION: Into a filament 10 for ignition means 11 to ignite combustible mixed fluid G stored in a storage container 1 in the first chamber 4, a preset current flows from a gas pressure monitoring circuit, 16 to measure the change of the electric resistance of the filament resulting from the pressure dependance of heat dissipation at this time. A gas generator with high reliability in a simple structure is thus obtained, in which the pressure drop of the combustible mixed fluid G can be detected.</p> |
