🔍 Key Concepts

• Primary functions of a hydraulic reservoir in shipboard systems • How hydraulic systems deal with heat, air, and contamination in the oil • Difference between components that store fluid vs. those that control pressure or absorb shocks

💭 Think About

• Think about what happens to hydraulic oil as it is pumped around the system – what needs to be done to that oil before it is reused? • Which component in a hydraulic system is actually responsible for controlling pressure and dealing with shock loads? Is that normally the job of the reservoir? • Which option best fits a large tank open (usually) to atmosphere, rather than a sealed, pressurized device?

✅ Before You Answer

• Eliminate any options that describe pressure control or shock absorption, and ask yourself which specific devices normally do those jobs (e.g., accumulators, relief valves). • Ask: is the reservoir usually pressurized, or is it mainly a storage and conditioning tank open to return flow? • Check which choice matches the idea of conditioning the fluid (removing air, cooling, settling contaminants) rather than mechanically supporting equipment.
