What is the function of a hydraulic reservoir?

The function of a hydraulic reservoir primarily revolves around its role in storing hydraulic fluid and supplying it to the hydraulic system as needed. In hydraulic systems, the reservoir acts as a dedicated storage tank where hydraulic fluid is kept until it is required for operation. This storage capability is crucial because it not only maintains a sufficient volume of fluid for the system to operate efficiently but also allows for the thermal expansion and contraction of the fluid as temperature changes occur during operation.

Additionally, the reservoir provides a place where air can separate from the fluid and allows any contaminants to settle at the bottom, but these functions are secondary to its primary role of storage. Ensuring that a proper amount of hydraulic fluid is available in the system is essential for maintaining consistent pressure, preventing cavitation, and allowing the system to recover from fluid loss due to leaks or other factors. Therefore, the primary and most essential function of a hydraulic reservoir is to store fluid and supply it to the hydraulic system when required.
