🔍 Key Concepts

• Hydraulic accumulator purpose in marine hydraulic systems • Difference between an accumulator and a reservoir • Typical overpressure protection devices in hydraulic systems (e.g., relief valves)

💭 Think About

• Ask yourself: What is the primary job of an accumulator—energy storage, fluid storage, or pressure control? • Which component normally serves as the main fluid tank in a hydraulic system, and is that the same as an accumulator? • Does safe design ever rely on only one device for overpressure relief?

✅ Before You Answer

• Identify which option best matches the idea of storing energy in the form of pressurized fluid. • Eliminate any answers that describe the normal job of a hydraulic reservoir rather than an accumulator. • Verify that overpressure protection is usually provided by relief valves, not solely by an accumulator.
