Abstract
A discal diaphragm body with a plurality of radially stress-relieving full-wave annular corrugations and a plurality of circumferentially stress-relieving full-wave radial spokes. The spokes follow and conform to the annular corrugations and are integrated with them to provide dual stress-relief and enhanced sensitivity for a pressure-responsive diaphragm.
Claims14
In a fluid pressure-responsive diaphragm, the combination of a discal body, a plurality of annular corrugations in said body in a radial periodic wave-form configuration to relieve radial tensile stress therein, and a plurality of radially-extending spokes in said body in a circumferential periodic wave-form configuration conforming to and integrated with the peaks and valleys of said annular corrugations to relieve circumferential tensile stress therein, each of said wave-forms modifying the other.
