Formed metal diaphragm with improved cycle life |
摘要 |
A formed metal diaphragm for use in fluid pressure regulators includes a dome-shaped central portion and a convoluted shaped flexible area. The convoluted shaped flexible area includes a series of radially spaced elliptically shaped impressions in the diaphragm surface. The major elliptic axis of each impression is aligned with a radius emanating from the center of the diaphragm. The minor ellipse axis of the impressions is located on a concentric axis outward from the center of the diaphragm.
