Abstract
The objective of the present invention is to provide a diaphragm damper with which the amount of volume change due to the resonance frequency and pressure can be set freely and the performance of the diaphragm damper can be optimized, without changing the attachment structure for a conventional metal diaphragm and without obstructing the space where fuel flows in a fuel chamber. To this end, this diaphragm damper, wherein a high-pressure gas is enclosed in a high-pressure chamber formed by two disk-shaped metal diaphragms the outer circumferential portions of which have been joined together, is constructed such that rubber-like elastic members are arranged within the high-pressure chamber.
