Which component is explicitly mentioned as contributing to faster cylinder motion when used with the pump?

• A. Accumulator
• B. Filter
• C. Cooler
• D. Valve

Answer: (A)

In hydraulic systems, cylinder speed is driven by how much fluid can be pushed into the cylinder per unit time. An accumulator is designed to store pressurized fluid and then release a burst of that fluid when needed. That burst provides extra flow to the cylinder, allowing a faster extension or retraction than the pump alone would deliver at that moment. It’s especially useful to overcome pump lag or demand spikes, giving the actuator a quick push without waiting for the pump to ramp up.

The other components don’t supply this rapid energy boost. A filter cleans contaminants but doesn’t increase flow. A cooler lowers temperature and helps maintain performance but doesn’t boost motion speed. A valve can regulate or redirect flow, but it doesn’t inherently provide additional energy to drive faster movement unless paired with a separate surge source. So the accumulator is the device explicitly enabling faster cylinder motion when used with the pump.
