Rotatable pipe coupling structure

摘要: The specification describes a rotatable multiple pipe coupling structure employing labyrinth seal between each stationary and its respective pipe. Because of no protruding parts from inner pipes into the channels, there will be minimized turbulence in fluids to transferred through structure. There is also described having corresponding are rotatably sealed with seal. structures according this invention may further provided driving shaft longitudinally centrally extending therethrough. applicable for revolving floor such as tower restaurants, changing surface area vehicle tires while motion, moving cranes, remote handling materials radio-active materials, gun turrets, helicopters, heavy mining machinery, wherever required transfer at least one fluid element element.
