<p>The invention relates to transport tubing switches consisting of a stator which is provided with at least six tubular connections and a rotor comprising at least three connecting cavities having different curvatures, such that one connection can be selectively connected to at least five different connections, and to the constituent elements of such switches. The invention also relates to a transport tubing switching method which enables selective switching between a tubular connection and at least five different connections and, in particular, multi-way and reversible switching, through the movement of a rotor comprising several connecting cavities in relation to a stator comprising several connections, said connecting cavities of the rotor having curvatures of 60< DEG >, 120< DEG > and 180< DEG > (straight cavity), of 45< DEG >, 135< DEG > and 180< DEG >, of 45< DEG >, 90< DEG >, 135< DEG > and 180< DEG >, or of 60< DEG >, 90< DEG >, 120< DEG > and 180< DEG >, and the tubular connections being mutually disposed at 45< DEG >, 60< DEG >, or at 60< DEG >and 90 DEG .</p> |
