Engine Control Variable Stator Valve Actuator
Overview
The engine control variable stator vane actuator is a linear actuator, with an integral two-stage, four-way electrohydraulic servo valve for control and position sensing for engine control feedback. Inputs to the engine control variable stator vane actuator are torque motor direct current, position feedback excitation voltage and regulated fuel pressure. The engine control variable stator vane actuator outputs are in the form of piston stroke and position feedback voltages.
