Within hydraulic systems, the energy transmission function is carried out via liquid matter transfer. This matter transfer, inextricably tied to energy transfer, provides the opportunities to perform two extra functions: heat transfer and lubrication. All this creates harsh constraints on the design, the integration and the operation of products relying on hydraulic power transmission. It is also important to limit fire hazards or the propagation of fire via the hydraulic fluid. This chapter first provides a summary of requirements and their corresponding solutions implemented to ensure the fluid is properly conditioned. The hydraulic system is equipped with observation (monitoring) and action (maintenance) means. Their goal is to ensure the fluid is in good condition, meaning present in sufficient quantity, clean, at an acceptable temperature and properly pressurized. The hydraulic fluid gives rise to the three basic energy phenomena: the resistive effect, the capacitive effect and the inertia effect.
