<p>Apparatus and method for integrating an actuator into turbo-machinery and operating the actuator based on process fluid associated with the turbo-machinery. The integrated actuator mechanism includes an actuator casing; a balance drum, with labyrinth seals, and recovery spring, configured to apply force to the balance drum, in the actuator casing; an actuation bar connected to the balance drum and configured to move linearly in the direction of the balance drum; and a connection mechanism connecting a diverted portion of turbo-machinery process fluid to the actuator casing for applying force, in an opposite direction of the spring force, to the balance drum. The labyrinth seals allow the diverted turbo-machinery process fluid to bleed through and return to the turbo-machinery.</p> |
