🔍 Key Concepts

• Mechanical-hydraulic governor operation – what happens to flyweights, speeder spring, and pilot valve when engine speed changes • Relationship between load decrease → engine speed change → flyweight movement • How movement of the floating lever is linked to the pilot valve plunger and power piston oil pressure in the illustration

💭 Think About

• When the engine load is suddenly reduced, does the engine tend to speed up or slow down? How does that affect the flyweights compared to the speeder spring force? • Look at the pivot points: if the top of the floating lever is pushed one way by the actuating linkage, which way must the right-hand end of the floating lever move? • Trace the motion from flyweights to speeder rod to floating lever to pilot valve: which component must move first, and what direction of motion of the pilot valve changes oil flow to the power piston?

✅ Before You Answer

• Identify which parts in the illustration move when engine speed increases with no change to the speeder spring setting • Verify which direction of motion of the pilot valve plunger causes oil to drain from under the power piston versus admit oil to it • Confirm how a decrease in fuel rack position (less fuel) would be produced: does that require increasing or decreasing oil pressure under the power piston?
