    Abstract: There is set forth herein an actuator having a housing and a piston assembly. The piston assembly can have a piston and a piston rod extending from the piston. In one embodiment, the housing can receive the piston and a portion of the piston rod. The piston assembly can define a piston assembly interior and a fluid reservoir can be located within the piston assembly interior. A chamber region within the interior of the housing can be separated by the piston assembly to define a piston side chamber and rod side chamber. The piston assembly can be moveable so that respective volumes of each of the piston side chamber and the rod side chamber are variable. For operation of the actuator by movement of the piston assembly within the interior of the housing, fluid can be moved between the reservoir and the chamber region.
