Which component would you use to provide a rapid, limited flow of oil to a downstream system to reduce startup time?

• A. Accumulator
• B. Pressure relief valve
• C. Check valve
• D. Piston pump

Answer: (A)

Energy storage for rapid hydraulic response during startup. An accumulator stores hydraulic energy and holds fluid at system pressure, ready to release a measured amount instantly when downstream demand appears. That quick pulse of oil fills lines and actuators right away, reducing the delay as the main pump ramps up and thus cutting startup time. The other options serve different roles: a pressure relief valve protects against overpressure, not to supply flow; a check valve prevents backflow; a piston pump provides continuous flow but does not deliver a pre-charged, short-duration pulse on demand.
