Abstract
A diaphragm assembly for servo motors has been provided wherein a pair of backing elements have opposed portions acting on opposite sides of a diaphragm assembly and are held in fixed relationship to each other through the means of a sonic weld located at a point remote from the diaphragm to provide a leak-proof diaphragm assembly which lends itself to ready modification to accept valves or diaphragms to change the operating characteristics for different applications.
