ABSTRACT:
An improved characterizing linkage assembly of the type utilized to proportion the flow of fluids in response to motor controls, such as in the control of fuel and air mixtures in industrial combustion systems. The linkage system comprises a cam assembly having an adjustable curvilinear cam band, which is rotatable by a drive shaft. A biased follower rod, bearingly supported for reciprocal movement, is urged against the cam band. Movement of the follower rod pivots a linkage actuator arm which is bearingly supported on the drive shaft. Rotation of the drive shaft in response to a change in a selected process parameter imparts movement to the cam band, the follower rod and thus the linkage actuator arm being the proportional travel.
