Abstract

A high pressure diaphragm for use with an electroexpansive material utilizes a generally planar central member, a generally outer flange-engaging member, and an annular ring member, which can have a frusto-conical shape, having its outer edge flexibly connected to the inner edge of the flange-engaging member and with its inner edge flexibly connected to the outer edge of the central member. The flexible connection includes a bridge member having a thickness less than the thickness of the annular ring member and maybe fabricated integrally with said annular ring member and with the central and flange-engaging members. In one embodiment the high pressure diaphgram is pre-loaded so that during movement no portion of the flexible connectors are in tension.
