🔍 Key Concepts

• simple hydraulic governor construction and flow path • purpose of speed droop and how oil pressure is controlled • difference between an actuating element (that moves the engine fuel rack) and an oil storage/accumulator element

💭 Think About

• Trace the path of oil from the pump: where is it stored under pressure before it is used to move something? • Which component is designed specifically to keep oil pressurized and ready, rather than to do the main work of moving the fuel control directly? • Ask yourself which part acts more like a "ready reservoir" of pressurized oil versus a working cylinder that spends the oil energy immediately.

✅ Before You Answer

• Identify which option is the working actuator that actually moves under oil pressure to change fuel or speed. • Identify which option is most like an accumulator or storage device for pressurized oil, not just a drain or low-pressure area. • Confirm which components in a hydraulic governor are normally at low pressure versus stored high pressure before actuation.
