A suspension system for an electromagnetic linear actuator armature includes plural suspension discs adjustably secured to the armature of the linear actuator. The discs include tortuous-path spring arms between inner and outer rims. The rims are stacked between annular spacers and retained by two annular clamps.

Force motor, multiple, parallel element linear suspension

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.

Linear actuator suspension system

A coupling device for interconnecting a drive shaft and a driven shaft which is maintained under fluid pressure to provide a tensile preload and which is specifically adapted for utilization with hydromechanical or electrohydraulic servovalves.
