Abstract

Electro-hydraulic proportional valve is the core control valve in many hydraulic systems used in agricultural and engineering machinery. To address the problem related to the large throttling losses and poor stability typically associated with these valves, here, the beneficial effects of a triangular groove structure on the related hydraulic response are studied. A mathematical model of the pressure compensation system based on the power-bond graph method is introduced, and the AMESim software is used to simulate its response. The results show that the triangular groove structure increases the jet angle and effectively compensates for the hydrodynamic force. The steady-state differential pressure at the valve port of the new pressure compensation structure was 0.65 MPa. Furthermore, experimental results show that the pressure difference at the main valve port is 0.73 MPa, and that the response time is less than 0.2 s. It is concluded that the new compensation structure has good pressure compensation response characteristics.
