ABSTRACT:
A device for slowing down the movement of the armature within a solenoid comprising a resilient container having a predetermined internal volume, and a dilatant material filling the container which material has as one of its properties at ambient temperatures, a non-resilient deformation when subjected to slow steady state stress, and a highly resilient resistance to deformation when subjected to rapid shock-like stress, whereby the container is connected to the solenoid in a manner affording its compression as the armature moves within the solenoid.
