 What is an open loop in an excavator? (Is an excavator an open loop or closed loop system?)

An open loop hydraulic system in an excavator refers to a system where the hydraulic fluid flows through the system only once and is then discharged. In an excavator, the open loop system uses a variable displacement pump, which allows the operator to control the flow of hydraulic fluid in response to the required power. On the other hand, a closed loop system recirculates the hydraulic fluid, resulting in increased energy efficiency and better control. Generally, most excavators operate on an open loop hydraulic system.
