This course is intended for third-year undergraduate students in mechanical engineering. It covers the curriculum for the module on Hydraulic and Pneumatic Systems. The first chapter provides a review of hydraulic fluids, their properties, flow regimes, and both singular and regular pressure losses. Knowledge of these concepts, with a sufficient theoretical background, is essential in understanding the physical phenomena that govern the study of these systems. The second chapter provides general technology on the different types of pumps and compressors, hydraulic motors, as well as their principles of operation, including some technical formulations. The third chapter discusses the various types of pneumatic cylinders, providing examples of their areas of application, and includes demonstrations for calculating and sizing the cylinder, as well as determining the forces acting on the cylinder rod. It concludes with the development of a control diagram for operating pneumatic cylinders using distributors, controls, and accessories. The fourth chapter defines hydraulic piping, the types of pipes, and devices for regulation, limiting, and reducing flow and pressure. The sixth chapter places particular emphasis on practical examples for controlling a pneumatic motor, a hydraulic motor with two rotational directions, and adjusting the speed of a cylinder rod. It ultimately presents a complete configuration for designing a hydraulic circuit.
