ABSTRACT:
The shaft of a linear actuator driven by a force motor preferably electromagnetic or hydraulic has a bifurcated arm positioned with one of the bifurcations on each side of the shaft and with the opposite end of the arm securely affixed to a torsion bar. The torsion bar has both ends thereof rigidly secured to a frame member. The bifurcations on the arm end contact a hub which defines a pair of side walls that are threadably received upon the end of the shaft. As the shaft reciprocates, a force is generated by the torsion bar colinear with the shaft axis motion which is proportional to the displacement of the shaft.
