  • What Is a Hydraulic System?

    Transporting liquid through a set of interconnected discrete components, a hydraulic circuit is a system that can control where fluid flows (such as thermodynamic systems), as well as control fluid pressure (such as hydraulic amplifiers). The system of a hydraulic circuit works similar to electric circuit theory, using linear and discrete elements.
