A method and apparatus for an electro-hydraulic actuator (1) having mechanical feedback provide closed loop control with a high degree of accuracy. The electro-hydraulic actuator (1) includes a current versus load generator (10), a single-stage servomechanism (20, 21, 22, 23), and a device (24, 25, 40, 41) for providing a mechanical feedback force for offsetting an input force (Fsol) of the current versus load generator (10).
1. An electro-hydraulic actuator comprising:a single stage servomechanism; a current versus load generator, said current versus load generator being capable of energizing said single stage servomechanism with an input force, said input force controlling said single stage servomechanism to regulate a regulated servo pressure controlled by said electro-hydraulic actuator, wherein said load generator includes a solenoid creating said input force; a control orifice; a flapper valve pivotably connected to said load generator and operatively engaged with said ...
