This paper is a study to apply EPPR valve for the electronic control of variable displacement hydraulic piston pump. In order to adjust the displacement of the pump, a regulator capable of controlling the swash plate angle is required. I apply the EPPR valve which is a valve that controls the output pressure by proportional current. It can be applied to control the swash plate angle with the advantage of excellent response, competitive price and electronic control. So this study deals with the development of analytical model and analysis of characteristics of EPPR valve by using SimulationX.
