"Hydraulic and Pneumatic Technical Manual" This manual consists of six articles. The first article introduces the flow theory and basic formulas of fluid mechanics in hydraulic and pneumatic systems. The second part introduces classical and modern control theory as well as measurement of fluid parameters and mechanical quantities, monitoring and failure analysis of hydraulic systems. The third and fourth chapters respectively introduce the working medium and power source of hydraulic and pneumatic systems; the structure and working principle of main hydraulic and pneumatic components and accessories; hydraulic and pneumatic
