    The unreasonable design of pressure differential valve may lead to unstable oil supply of aero-engine lubrication system. In order to find the optimization method of pressure differential valve structure, taking the oil supply subsystem of lubrication system as the research object, to study the effect of different pressure differential valve structure parameters on the oil supply pressure characteristics of aero-engine lubrication system by using a combination of numerical simulation and experimental verification. The results show that: (1) The reduction of spool damping hole diameter can improve the stability of oil supply pressure, but the dynamic performance becomes worse, and there is a large pressure peak; (2) Increase the diameter of the overflow hole can optimize the dynamic characteristics and stability of the oil supply pressure at the same time, to achieve stable oil supply; (3) Reduce the spring stiffness can weaken the oil supply pressure fluctuations and improve the stability of oil supply, but the pressure overshoot and rise time increase, resulting in poor dynamic performance.
