This paper deals with the theoretical-experimental study of a hydraulic system used in the mobile equipment area, more specifically in tractors. The main components of the system are a variable displacement axial piston pump with pressure and flow compensation, two directional control valves with pressure compensation and linear and rotary actuators. Two main results are presented: Firstly, the energy efficiency with the system operating with both individual loadings and with loadings applied simultaneously is discussed. Secondly, the evaluation of the level of interference of one actuation circuit on another is analyzed. These results allow the identification of the best operational conditions that can be obtained for real mobile equipment.
