Which combination is associated with faster cylinder actuation in the given scenario?

• A. Regulating valve closed alone
• B. Reservoir removed
• C. Filter replaced
• D. Accumulator used with the pump

Answer: (D)

Faster cylinder actuation comes from delivering hydraulic fluid to the cylinder more quickly when the stroke begins. An accumulator stores pressurized fluid and can release a rapid burst into the system, providing a surge of flow that the pump alone may not supply instantly. This short, high-flow impulse overcomes inertia and quickly ramps the cylinder to operating speed, so using an accumulator with the pump directly enables faster actuation. The other scenarios don’t provide that immediate flow boost: closing the regulating valve alone throttles flow and slows movement; removing the reservoir starves the system of fluid and can stall or crash performance; replacing a filter might improve flow if a clog was limiting it, but it doesn’t inherently deliver the large, rapid surge an accumulator can provide.
