ABSTRACT:
An apparatus for connection between relatively movable parts. The apparatus includes a variable volume chamber having a first portion for connection with one of the parts and a second portion for connection with another of the parts. The chamber has fluid therein for resisting movement of the parts relative to each other. A valve controls the fluid flow from the chamber to a location at which the fluid does not resist relative movement of the parts. The valve includes a valve member movable from a first position to provide fluid communication between the chamber and the location. An electroviscous fluid control device resists movement of the valve member form the first position.
