Abstract:
In a snap acting thermostatic disc assembly including a thermostatic disc element with opposite first and second face surfaces with a weld slug placed on a portion of said first face surface of said thermostatic disc element which is welded to the disc element causing a heat affected zone of the thermostatic disc element, the thermostatic disc assembly in turn being attachable to a support for mounting in a device, the thermostatic disc element having a first concave curved configuration relative to a selected direction and a second reversed convex curved configuration relative to the selected direction in dependence upon the temperature of the thermostatic member, a method of increasing the cycle life of the thermostatic element comprising the step of engaging the second face surface of the disc element with a fulcrum member at a location spaced from the heat affected zone so that upon reversal of the curvature of the disc element, the disc element will bend about the fulcrum member at a location removed from the heat affected zone.
