Abstract:
Embodiments include a self-centering control rod device having two independently operating springs, a bushing, and a control rod. The two springs utilize preload compression to maintain the control rod centered. One spring operates directly against the control rod while the other operates against the bushing. Each spring may have different spring strength or established preload in order to balance out the application force required to control a particular object. Spring compression force adjustments on one spring do not affect the center point or the spring compression force adjustment of the other spring.
