ABSTRACT:
A high-pressure accumulator is provided which protects a diaphragm from abnormal displacement. A high-pressure vessel 101 is provided with support portions 107, 108 having contact portions facing the vicinity of the central portion of a diaphragm 106. The support portions are annular and have the same center as that of the high-pressure chamber. The support portions may also have a plurality of holes. The support portions have curved surfaces 107a, 108a which make contact with the diaphragm uniformly when the diaphragm is displaced. In addition, the support portions may be either integrated with or separated from a case 101. A seal portion is disposed on the cylindrical outer wall 109a of a plate 109 disposed in a position on the opposite side of the diaphragm 106 from the case 101.
