Static Characteristics of the New Type Nozzle Flapper Amplifier for Double Nozzle Flapper Electro-hydraulic Servo Valve

摘要：

　　A new type nozzle flapper amplifier for double nozzle flapper electro-hydraulic servo valve is proposed in the paper.The electro-mechanical converter of new type nozzle flapper amplifier is designed by using the piezoelectric bimorph and beryllium-bronze materials.The structure and working principle of the new type nozzle flapper amplifier are introduced.Pressure characteristic and flowrate characteristic are analyzed by experimental method.The research results show that pressure characteristic has large amplification factor and output pressure; flowrate characteristic has large linear range and output flowrate.
