These actuators are electro-hydraulic devices which combine all the basic elements of a hydraulic system into one integral unit, consisting of: an electric motor driving a hydraulic pump, piping, working cylinder and piston. 

The function of the actuator is to convert electrical energy, hydraulically, into a mechanical force, producing a smooth straight line thrust, throughout the piston stroke.
