🔍 Key Concepts

• Follow-up (restoring) action in a turbine governor prevents hunting by feeding the motion of the steam valve back to the governor mechanism. • In this SE-0009 illustration, the restoring linkage connects the steam-operating (servo) mechanism back to the governor head so the pilot valve is re-centered after movement. • Only the part that is mechanically tied BOTH to the governor and to the nozzle valve operating gear can provide true follow-up.

💭 Think About

• Look at how the movement of the steam operating valves on the right-hand side is sent back toward the governor on the left. Which labeled part is clearly part of that feedback path? • Ask yourself: if the turbine speed changes and the governor moves the pilot valve, which part then moves in response to the servo piston/operating valves and pushes the governor mechanism back toward neutral? • Compare the labels near the words "restoring linkage" and the connection to the nozzle valve operating piston. Which of the answer letters is associated with that component?

✅ Before You Answer

• Verify which labeled part is physically connected to BOTH the governor mechanism and the nozzle-valve operating mechanism — that is the feedback or restoring element. • Confirm that the part you choose does NOT directly sense speed (not the flyweights or speed-setting device) and does NOT directly open steam to the turbine (not the main steam valves), but instead transmits motion back to the governor. • Double-check the lettering around the restoring linkage drawn at the top/right of the figure and follow where that same linkage meets the governor head to match it with one of the answer choices.
