🔍 Key Concepts

• Study how pressure oil, compensating oil, and sump oil move through the governor in the MO-0096 diagram. • Focus on the labeled parts near letters A, B, C, and D and read the small labels such as speed droop lever spring, compensating needle valve, and spring-loaded accumulators. • Recall the basic purpose of a hydraulic governor: to control engine speed and prevent hunting or overspeed as load changes.

💭 Think About

• For each choice, ask yourself: does that description match the function of the specific component that the arrow and label are pointing to in the illustration? • Compare the words in the answer choices (like speed droop, compensating, and accumulators) to the exact components in the diagram—do they operate on oil flow, spring force, or mechanical position? • Think about which part of the governor would logically prevent racing or hunting versus which part would store or release high-pressure oil or adjust for steady‑state speed droop.

✅ Before You Answer

• Verify which component in the drawing actually controls speed droop and how it acts on the speeder spring or terminal shaft. • Verify which component in the drawing is tied to the compensating piston and needle valve and how that relates to changing load and transient speed control. • Verify in the illustration what the spring-loaded accumulators are connected to (pressure line, return to sump, or control port) and whether they are shown as simply storing oil or actively releasing it to the sump.
