发明名称 Methods and apparatus for mechanically adjusting a null offset in a torque motor of a servovalve
摘要 A servovalve assembly includes a motor having a flapper shaft. A flapper couples to a first end of the flapper shaft such that the flapper shaft orients the flapper between a first nozzle and a second nozzle of the servovalve assembly. An adjustment assembly adjusts a position of the flapper relative to the nozzles of the servovalve. The adjustment assembly enables a servovalve manufacturer to set the flapper of the servovalve at a null position without disassembling the servovalve. Rather, the manufacturer is capable of simply installing the adjustment assembly and deforming an arm portion of the adjustment assembly for proper null position calibration.
