The diaphragm (2) has an outer flange and an inner portion which is deflectable relative thereto, the inner portion having a lone, primary annular corrugation (12) connecting a center (4) of the inner portion to the outer flange and which, when viewed in cross section, has the general shape of one full cosine wave (12). A plurality of radially disposed waves (16) present ridges to the high pressure side of the diaphragm. Each of the radial waves is arithmetically added to the primary wave (12) so as to be integral therewith and has the general shape of one full cosine wave when viewed in cross section both along and normal to the length of the ridge. |
