Abstract:
1. A fuel supply apparatus for supplying a low boiling point fuel which is in gaseous phase at a room temperature under atmospheric pressure, comprising a fuel storage unit storing the low boiling point fuel; a fuel feeding unit feeding the low boiling point fuel from said fuel storage unit; a fuel piping passing the low boiling point fuel fed from said fuel storage unit; a fuel leakage preventing unit preventing leakage of the low boiling point fuel in said fuel storage unit or said fuel piping; a fuel leakage detecting unit detecting leakage of the low boiling point fuel in said fuel storage unit or said fuel piping; a fuel state detecting unit detecting state if the low boiling point fuel in said fuel storage unit or said fuel piping; and a fuel state control unit controlling state of the low boiling point fuel in said fuel storage unit or said fuel piping, wherein said fuel storage unit is provided with said fuel leakage preventing unit, said fuel leakage presenting unit is constructed with containing expandable elastomer, and the low boiling point fuel is stored within said elastomer, said fuel feeding unit containing at least a pump fed fuel to said fuel piping from said fuel storage unit and a magnetic valve for controlling an amount of fuel passing said fuel piping and a discharge pressure of said pump or a opening degree of said magnetic valve is controlled depending upon the result of detection by said fuel state detecting unit and said fuel leakage detecting unit.
