In many industrial processes the variation of pressure in hydraulic systems can directly affect products that are being manufactured. So it is important to know the fundamental characteristics of construction of hydraulic components so that they can contribute positively during the use of hydraulic machines. This study aimed to analyse the characteristics of the variation in supply pressure in a hydraulic system under different conditions of operation. In the initial phase was presented constructive operating characteristics of the major components analysed, these being the proportional directional valve, pressure relief valve direct operated (relief valve) and the accumulator. Subsequently, was determined the relation between the operation of the relief valve and the behavior of supply pressure. In the experiments, the proportional directional valve is subjected to different conditions of pressure difference and aperture alternating, and also the use of an accumulator in the circuit. The results show the relation between the operating conditions of the hydraulic circuit and the change in supply pressure.
