PROBLEM TO BE SOLVED: To provide an accumulator vessel 1 for accumulating a fuel in a high pressure state, capable of reducing pressure pulsation without increasing a volume of an accumulator.SOLUTION: An accumulator vessel 1 includes a first accumulator 2 for accumulating a fuel supplied to a combustion chamber of an internal combustion engine in a high pressure state, and a second accumulator 3 made of a material having elasticity lower than that of the first accumulator, and communicated with the first accumulator 2 to accumulate the fuel in a high pressure state. Thus the second accumulator 3 can be applied as a region of high damper effect, so that pressure pulsation can be reduced without increasing a volume of the accumulator as a whole. |
