ABSTRACT:
In accordance with the teachings of the present invention, a hydraulic actuator is described which is operable to generate forces. The hydraulic actuator includes a pressure cylinder as well as a piston disposed within a pressure cylinder and being operable to divide the pressure cylinder into first and second portions. The hydraulic actuator also includes a piston rod mechanically communicating with the piston and being operable to impart movement to the piston. Finally, the hydraulic actuator includes variable restriction valves for controlling the pressure on both sides of the piston substantially independent of the velocity of the piston within the pressure cylinder.
