摘要
Diaphragm interface apparatus to improve a cycle life of a diaphragm are described. An example fluid regulator includes a fluid flow passageway between an inlet and an outlet, where a sensing chamber defines a portion of the fluid flow passageway. A diaphragm senses a pressure in the sensing chamber and a diaphragm interface adjacent the sensing chamber has a curved surface to contact a portion of the diaphragm that moves in response to pressure changes in the sensing chamber. The curved surface affects an amount of stress imparted to the portion of the diaphragm during operation of the fluid regulator.
