In hydraulic systems, accumulators primarily function as cushions against pressure surges.

• A. Dampers against noise
• B. Storage of hydraulic fluid
• C. Cushion against pressure surges
• D. Temperature regulation

Answer: (C)

Accumulators act as a hydraulic spring, storing energy as compressed gas and hydraulic fluid so they can respond quickly to changes in demand. Their main job is to cushion pressure surges and dampen shocks when pumps start or valves close, smoothing out pressure fluctuations and protecting components from spikes. By releasing fluid or absorbing energy as needed, they help keep system pressure stable between pump cycles and during abrupt changes in flow. They aren’t primarily used for noise damping, bulk fluid storage, or temperature control, which is why cushioning against pressure surges is the best description of their primary function.
