In this arrangement, the presence of the accumulator with the pump primarily affects which aspect of the cylinder's operation?

• A. Oil temperature
• B. Flow rate of hydraulic oil to the cylinder
• C. Filter cleanliness
• D. Cylinder size

Answer: (B)

An accumulator stores energy as pressurized fluid, so its main effect is on how much oil can reach the cylinder and how quickly it gets there. When the cylinder needs a rapid move, the accumulator can release its stored fluid, boosting the instantaneous flow rate to the cylinder and improving speed and responsiveness. It also helps smooth pressure and reduce pump cycling, but the key impact on the cylinder’s operation is the flow delivered to it. Oil temperature isn’t directly driven by the accumulator’s presence; it’s more about overall power dissipation and cooling. Filter cleanliness and cylinder size aren’t directly changed by adding an accumulator—the former depends on filtration, and the latter is a fixed design attribute.
