What is one key role of an accumulator in a hydraulic system?

In a hydraulic system, an accumulator plays a crucial role by storing hydraulic energy in the form of pressurized fluid. This stored energy can be released when needed to assist in operating hydraulic components, such as actuators or pumps, thereby helping to maintain pressure and flow in the system. The accumulator allows the system to handle varying loads efficiently and can provide a supplemental pressure source during peak demands.

Additionally, by storing energy, the accumulator can help smooth out pulsations in the hydraulic system and serve as a buffer during sudden changes in demand. This capability enhances the overall efficiency and responsiveness of the hydraulic system, making it a vital component in various applications, from industrial machinery to automotive systems.
