Abstract
Several versions of a flex joint (10, 100, 200) are provided which provides for relative flexible movement between a first member and a second member about a pivot point. The pivotal motion is provided by the use of elastomeric assemblies which are placed in elastomeric shear as one member pivots relative to the other. With each of the flex joints, at least two concentric and separate passages are formed through the flex joint for carrying fluids and the like through the flex joint. The passages remain separate and essentially unchanging in cross-section throughout the entire range of pivotal motion of the flex joint.
