<p>PURPOSE: A directional fluid line is provided to minimize flow loss because a front lateral side has an inclination angle lower than the inclination angle of rear lateral sides. CONSTITUTION: A directional fluid line comprises an inner contour(2) with wave peaks(4) and wave troughs(5) and an outer contour. Each wave peak has a front lateral side(6) and rear lateral sides(7). The front lateral side has an inclination angle lower than the inclination angle of the rear lateral sides. The outer contour is parallelly extended from the inner contour.</p> |
