N2 - Nowadays, more and more attention has been paid to the flapper deflection servo valve for its long service life and lasting antifouling. As a core part of flapper deflection servo valve, deflector pilot stage's performance has a serious impact on the capability of the entire servo valve. Aiming to improve the performance of deflector pilot stage and observing the cavitation variation of flow field, this paper establishes a suitable numerical simulation model of the deflector pilot stage by software STAR-CCM+. New performance parameter whose name is pressure-sensitive coefficient number is proposed to reflect the character of pressure variation in deflector pilot stage. By changing the configuration of inlet nozzle, the cavitation variation and pressure-sensitive coefficient number are analyzed to get a higher performance. At last the best size is obtained which include the height, width and the position of symmetrical characteristic.
