🔍 Key Concepts

• Variable displacement pump operation in an electro-hydraulic steering gear • Relationship between helm (command) position and rudder actual position • How a feedback / follow-up system controls pump stroke in steering gear

💭 Think About

• Think about what actually makes the pump change from zero stroke to pumping oil: is it a valve being opened, pressure relief lifting, or a control signal from the steering gear follow-up system? • In normal operation, does the pump keep stroking any time the wheel is not exactly amidships, or only when the rudder has to move to correct a difference between ordered and actual rudder angle? • Which option best describes a control condition (an error or difference to be corrected) rather than just a physical position or a safety/relief event?

✅ Before You Answer

• Identify which choice describes a difference between commanded and actual rudder angle (this is what a follow-up system reacts to). • Eliminate any options that are related mainly to safety devices (like relief valves) rather than normal control. • Verify which option reflects a condition where the system must move the rudder rather than simply hold it in position.
