Chapter 7 Basic Hydraulie Circuits Introduction Any hydraulic system is constituted by several basic hydraulic circuits.A hydraulic basic circuit is a group of components. Let's classify:the functions in hydraulic system by: pressure control circuits:control entire or partial operating pressure; speed control circuits:control and regulate motion speed of actuator elements; Directional control circuits:control and shift motion direction of actuator; Multi-actuator control circuits:control and shift operating cycle between several actuators.
