Diaphragm stopper construction for a high-pressure accumulator

摘要

A diaphragm stopper construction for a high-pressure accumulator is provided which prevents excessive concentrations of stress in a diaphragm. The curve of the contact surface of a stopper includes a first curve for the perimeter portion of a diaphragm 86 which is determined on the basis of a first equation expressing deflection when a disk secured around its circumference is subjected to a uniformly distributed load; and a second curve for the central portion which is determined on the basis of a second equation expressing large deflection when a disk secured around its circumference is subjected to a uniformly distributed load.
