The effective way to improve the reliability of fuel metering system in an aero-engine is use a high-speed on/off valve (HSV) instead servo as pilot stage valve. However, dynamic performance easily affected by HSV, so novel two-stage with adjustable maximum opening (AMOHSV) proposed which stroke main regulated rod. Firstly, structure and working principle are presented. Then, entire mathematica...
