ABSTRACT:
A linear actuator and method whereby linear movement of a drive rod is achieved in a step-wise fashion using a pair of clamping members in conjunction with extension members. The body of the linear actuator is configured as a pair of housings, each with a clamping member and slidably receiving the extension member. Each clamping member is each actuated by a magnetostrictive rod. A third magnetostrictive rod slidably passes through both housings and ends in abutment with each clamping member. The clamping members selectively affix the respective housing to the drive rod while the extension member pushes one clamping member relative to the other clamping member. A spring resiliently urges the two housings together and thereby cooperates with the two clamping members and the extension member in moving the linear actuator along the length of the drive rod.
