Directional fluid line

#The present application claims priority under 35 U.S.C. §119 of German Patent Application No. 10 2011 015 388.8, filed on Mar. 29, 2011, the disclosure of which is expressly incorporated by reference herein in its entirety.

#1. Field of the Invention

#The invention relates to a fluid line with an inner contour that has wave peaks and wave troughs. The wave peaks in each case have a front flank and a rear flank.

#The present invention is further described in the detailed description which follows, in reference to the noted plurality of drawings by way of non-limiting examples of exemplary embodiments of the present invention, in which like reference numerals represent similar parts throughout the several views of the drawings, and wherein:

#The FIGURE illustrates a cross section through a fluid line according to embodiments of the invention.

#The particulars shown herein are by way of example and for purposes of illustrative discussion of the embodiments of the present invention only and are presented in the cause of providing what is believed to be the most useful and readily understood description of the principles and conceptual aspects of the present invention. In this regard, no attempt is made to show structural details of the present invention in more detail than is necessary for the fundamental understanding of the present invention, the description taken with the drawings making apparent to those skilled in the art how the several forms of the present invention may be embodied or formed in practice.

#The FIGURE shows a fluid line 1, which is embodied or formed as a corrugated pipe. Fluid line 1 has an inner contour 2, which is optimized in terms of flow with respect to a predetermined flow through direction, symbolized by arrow 3.

#Inner contour 2 has wave peaks 4 and wave troughs 5. A front flank 6 and a rear flank 7 are assigned to or associated with each wave peak 4. An inclination angle of front flank 6 is smaller than an inclination angle of rear flank 7. The inclination angle for flanks 6 and 7 corresponds to an angle between flow through direction 3 and a surface on respective flank 6, 7. Since fluid line 1 is generally embodied or formed in a rotationally symmetrical manner, a rotation (and longitudinal) axis 8 runs parallel to flow direction 3. The inclination angle can thus also be measured between rotation axis 8 and a respective one of front flank 6 or rear flank 7.
