Abstract
A force limiter to be interposed between an actuator and a device to be moved by the actuator to limit the force applied by the actuator. The force limited has a body having a chamber and open at at least one end. There is a piston slidable within the body. A piston rod extends from the piston through, and slidable within, the open end of the body. Resilient members such as Belleville washers are positioned in the chamber between the piston and an end of the chamber away from the piston. The resilient members are calibrated to provide the necessary force limit and are able to apply that force limit in both directions of movement of the actuator. The force limiter can be attached to the actuator.
