Define 'hydraulic circuit.'

A hydraulic circuit is fundamentally a path through which hydraulic fluid flows to transmit power and perform work. This definition encompasses the essential components of hydraulic systems, including pumps, actuators, and control valves, which all work together to generate force or movement through the hydraulic fluid. The circuit's design allows the fluid to navigate through various paths, enabling linear or rotary motion, depending on the application. This efficient transfer of energy through the hydraulic fluid is key to various industrial applications, such as lifting, clamping, or driving machinery. By providing this path, the hydraulic circuit is crucial to the functionality of hydraulic systems, allowing them to operate effectively in different environments.
