🔍 Key Concepts

• Electro-hydraulic steering systems components and their functions • How pressure spikes and shocks are controlled in hydraulic systems • Typical purpose of relief valves vs. accumulators vs. springs vs. gears

💭 Think About

• Which component in a hydraulic system is specifically designed to limit excess pressure to protect piping and machinery? • Think about what happens when the rudder hits a hard stop or heavy seas slam the rudder—what device responds instantly to a sudden rise in pressure? • Among the choices, which parts are mainly for motion/position control and which are mainly for pressure protection?

✅ Before You Answer

• Identify which choice is primarily used for pressure limitation or protection in hydraulic systems. • Eliminate any options that mainly deal with mechanical alignment, gearing, or centering rather than pressure control. • Confirm from your steering gear knowledge which component reacts when hydraulic pressure exceeds a set safe limit.
