What is the role of a pressurized reservoir in a hydraulic system?

The role of a pressurized reservoir in a hydraulic system is to provide a flow of fluid to hydraulic pumps. This is crucial because the reservoir acts as a source of hydraulic fluid, ensuring that the pumps have a consistent supply required to generate hydraulic pressure. The pressurization of the reservoir helps maintain fluid flow and prevents cavitation, which can occur if the hydraulic pump does not receive enough fluid. By maintaining pressure, the reservoir supports the reliable operation of the hydraulic system, allowing for efficient transfer of power to various components like actuators and valves, thereby enabling the effective functioning of the entire hydraulic system.
