ABSTRACT:
A fluid pressure-responsive diaphragm comprising a discal body and a holding ring. The holding ring is fastened to the discal body and has an outwardly turned lip formed at the inner edge of the holding ring. The holding ring has a different thickness than the thickness of the discal body. Both the discal body and the holding ring are made of metallic substances. The discal body has a plurality of annular corrugations in a radial periodic waveform configuration and a plurality of radially extending spokes in a circumferential periodic waveform conforming to and integrated with the peaks and valleys of the annular corrugations. The holding ring is fastened to and aligned with the periphery of the discal body and the outwardly turned lip is adjacent to the outermost annular corrugation. A compressible seal is juxtaposed within the area defined by the outwardly turned lip and a surface of the holding ring.
