Abstract:
Methods and apparatus for adjusting a spring load in an actuator are described. An example actuator includes a housing and a plate. Further, the example actuator includes one or more springs disposed in the housing to apply a force to the plate. Additionally, the example actuator includes a spring load adjuster having a collar extending through and movably engaged to the plate to enable an adjustment of the position of the collar relative to the plate to change a load provided by the one or more springs.
