Cmove inward and the pilot valve (piece 10
DC
AI Explanation
The correct answer is C) move inward and the pilot valve (piece 10). When the load is removed, the speed of the engine increases. In an isochronous hydraulic governor, this increased speed causes the balance piston (piece 22) to move inward, which in turn moves the pilot valve (piece 10) inward. This action adjusts the fuel supply to the engine, reducing the speed and maintaining a constant RPM. The other options are incorrect because the balance piston does not move outward (A), and the correct answer is specifically about the pilot valve moving inward (C), not just the general movement of components (B and D).
