Abstract

A region (3) of the tube (1) is held to the tube to flex within limits so as to be moved to and fro to modify the passage section of the tube. The flexible region forms part of a side sector of a cylindrical casing which extends axially from the tube entry over a prescribed length of the tube. The region (3) is clamped to the tube by a flexible cuff (4,5) which in turn folds up into a collar in the tube part, affording the minimum passage.

Der flexible Teilbereich kann dabei auf einfache Weise einen seitlichen Ausschnitt eines Zylindermantels dar­ stellen, der sich von der Eintrittsöffnung des Ansaugroh­ res in einer vorgegebenen Länge im Verlauf des Ansaugroh­ res axial erstreckt. Bevorzugt ist der Teilbereich über eine flexible Manschette an das Ansaugrohr angebunden, die in dem Zustand in dem der Teilbereich an das Ansaug­ rohr zur Herstellung des kleinstmöglichen Durchtritts­ querschnitts angedrückt ist, zu einem Wulst faltbar sein kann. Hierzu kann auf einfache Weise die Breite der axia­ len Manschette an die erforderliche Querschnittsverände­ rung angepasst werden.The flexible section can be done easily a lateral section of a cylinder jacket  from the inlet opening of the intake pipe res in a predetermined length in the course of the intake pipe res extends axially. The partial area is preferably above a flexible sleeve connected to the intake pipe, which in the state in which the partial area to the intake Pipe for the smallest possible passage is pressed cross-section, to be foldable into a bead can. The width of the axia len cuff to the required cross-sectional changes be adjusted.

Beschreibung des AusführungsbeispielsDescription of the embodiment

In Fig. 1 ist eine Ansaugvorrichtung mit einem Ansaug­ rohr 1 für einen hier nicht dargestellten Verbrennungsmo­ tor gezeigt, durch die ein Luftstrom gemäß Pfeil 2 ange­ saugt wird. Das Ansaugrohr 1 weist einen Teilbereich 3 als Ausschnitt des Zylindermantels des Ansaugrohres 1 auf, der über flexible Manschetten 4 und 5 am Ansaugrohr gehalten ist. Die Veränderung der Querschnittsöffnung des Ansaugrohres 1 kann hier dadurch erreicht werden, dass der Teilbereich 3 unter Zusammendrücken der Manschette 4 zur Achse des Ansaugrohres 1 in Richtung A hingedrückt wird.In Fig. 1, an intake device with an intake pipe 1 for a combustion engine, not shown here, is shown through which an air flow according to arrow 2 is sucked. The intake pipe 1 has a section 3 as a cutout of the cylinder jacket of the intake pipe 1 , which is held on the intake pipe via flexible sleeves 4 and 5 . The change in the cross-sectional opening of the intake pipe 1 can be achieved here in that the partial area 3 is pressed toward the axis of the intake pipe 1 in direction A while compressing the sleeve 4 .

Aus Fig. 2 ist die Lage der Manschette 4 bei einem rela­ tiv großen Querschnitt des Ansaugrohres 1 zu entnehmen. Aus Fig. 3 kann man die Faltung der Manschette 4 bei ei­ nem verkleinerten Querschnitt erkennen, die entsteht, wenn der Teilbereich 3 nahezu vollständig an die anderen Bereiche des Ansaugrohres herangedrückt ist.From Fig. 2, the position of the sleeve 4 with a rela tively large cross section of the intake pipe 1 can be seen. From Fig. 3 you can see the folding of the sleeve 4 with egg nem reduced cross-section, which occurs when the portion 3 is almost completely pressed against the other areas of the intake pipe.
