<p><P>PROBLEM TO BE SOLVED: To provide a high pressure accumulator which protects a diaphragm against an abnormal deformation in the diaphragm. <P>SOLUTION: Support parts 107 and 108 having contact surfaces opposing near a central part of the diaphragm 106 are provided in a high pressure vessel 101. The support parts are concentric circle rings. The support parts may have a plurality of holes. The support parts have curvature surfaces 107a and 108a with which the diaphragms uniformly touch the surface when the diaphragms deforms. The support parts may be incorporated with or separated from the vessel 101. A seal part is provided at an outer peripheral cylindrical surface 109a of a plate 109 set in the position opposite to the vessel 101 with the diaphragm 106 between. <P>COPYRIGHT: (C)2003,JPO</p> |
