ABSTRACT:
A mechanical device forms part of a limiter assembly associated with reversible electric actuators. Typically, such an actuator is for controlling pipeline valves. The limiter assembly comprises a mechanism by which one or more limiters can be held in the engaged position even after the trigger has been deactivated. The undesirable phenomenon of hunting or pumping (the effect of the actuator motor cutting in and out repeatedly) is prevented by a simple flexible ribbon with teeth positioned in such a way as to engage corresponding sprockets that are capable of rotation on their respective shafts in only one direction.
