Hydraulic systems are designed to transfer forces in a controlled way by means of fluids. They are used not only in automotive engineering, but also in the drive, control and regulation technology of mechanical engineering, aviation and aerospace, shipbuilding, earthmoving and road construction, and agriculture. The following overview describes not only the basic principles of hydraulic systems, but also the functions and operation of components and auxiliary systems. By using hydraulic diagrams with the most commonly used components and calculations, control engineering is explained in an accessible way.
