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)

Providing a rapid, limited flow during startup comes from storing hydraulic energy and releasing a quick pulse when demand rises. An accumulator does just that: it stores oil under pressure with a pre-charged gas or spring on the other side, so when startup begins it can instantly deliver a short burst of oil to the downstream line. This quick surge helps move the actuator or valve sooner, reducing overall startup time, while the pump continues to build up steady pressure. The other components don’t supply this stored-energy burst: a pressure relief valve shuttles excess pressure to the tank and doesn’t provide flow to the load; a check valve only prevents backflow; a piston pump delivers flow but does not act as a short-term storage source for a rapid startup.
