Abstract: The assembly includes a plurality of linear actuator modules or units capable of being readily interconnected in various transversely extending orientations relative to each other. The units are so constructed as to effect internal conduction of electrical and fluid energy sequentially between each other and to an energy consumer affixed to the terminal one of them. Each unit includes a pair of elongate and reciprocatorially moveable support members having energy conducting passageways extending therethrough and alignable with desired ones of a plurality of energy receiving openings provided within the frame of the next unit.
