Abstract
Official abstract text for this publication.
A diaphragm accumulator provided with a flexible diaphragm inside an accumulator housing has a stress relaxing member having a contact surface which the diaphragm deformed by a pressure fluctuation inside the accumulator housing contacts and regulating the deformed attitude of the diaphragm by the contact surface on the inner surface. When the diaphragm is deformed by the pressure fluctuation inside the accumulator housing, the stress relaxing member regulates the deformed attitude of the diaphragm to reduce a stress generated in the diaphragm.
First claim
Opening claim text (preview).
The invention claimed is: 1. An accumulator comprising: an accumulator housing; an annular diaphragm holder fixed to an interior surface of the accumulator housing; a flexible diaphragm provided inside the accumulator housing in such a manner as to divide an inside of the accumulator housing, and end of the flexible diaphragm being sandwiched between the annular diaphragm holder and the interior surface of the accumulator housing; and a resin or rubber stress relaxing member provided inside the accumulator housing and regulating a deformed attitude of the diaphragm deformed by a pressure fluctuation inside the accumulator housing by contact of the diaphragm with the stress relaxing member, the stress relaxing member including a first portion that extends along the annular diaphragm holder and a second portion that extends along the interior surface of the accumulator housing, and a contact surface of the stress relaxing member that is configured to contact the diaphragm and that connects the first portion to the second portion is convexly formed such that the contact surface protrudes in a direction toward an interior of the accumulator housing. 2. The accumulator according to claim 1 , wherein an inner diameter dimension of the convexly formed contact surface gradually reduces as a distance between convexly formed contact surface and the diaphragm increases in an axial direction away from the diaphragm.
