摘要： PROBLEM TO BE SOLVED: To detect the leak of flow control valves in a short time by controlling the flow control valves into the full closed state and judging it leak when the detection value of a flow sensor arranged in the upstream side of a flow than the flow control valves is larger than the prescribed leak detection reference value. SOLUTION: A first fuel control valve 4, a second fuel control valve 5, and a ball valve 9 are controlled into the full closed states by a leak judgment controller 14. The leak judgment device 14 obtains the detection value of a flow sensor 13 to judge whether the flow value is larger than a prescribed detection reference value. When the detection flow value is larger than the leak detection reference value, it is so judged that either the first fuel control valve 4 or the second fuel control valve 5 is leaked. This constitution can eliminate such a restriction as not judging the leak except for the timing after elapsing a prescribed time so as to detect the leak in a short time.
