ABSTRACT:
An improved power actuator with lost motion arrester for coupled use in accomplishing remote control, set, and set hold of rotary flow control valve adjustments wherein the lost motion arrester component is comprised of a circular rack and pinion timing gear assembly that functions to allow smooth mechanical operation during displacement of the power actuator to accomplish valve adjustment, but upon any valve adjustment set stop instantaneously provides in coupled combination with the power actuator assembly a positive mechanical lock and hold function in arresting the lost motion action by which operational adjustment and set of the power actuator mechanism is made.
