A hydraulic system, from a general perspective, is an arrangement of interconnected components that uses a liquid under pressure to provide energy transmission and control. It has an extremely broad range of applications covering basically all elds of production, manufacturing and service. Consequently, the energy transmission and control requirements are very diverse and thus the structure of each hydraulic system has its specicities.
