Fig. 1 einen aus einem federnden Blechstreifen geformten Strömungsgleichrichter in perspektivischer An­ sicht, Fig. 1 view a formed from a resilient sheet metal strip flow rectifier in perspective An,

Fig. 2 den Strömungsgleichrichter als Einsatzkörper im Luftansaugrohr, Fig. 2 shows the flow rectifier as an insert body in the air intake pipe,

Fig. 3 den eingebauten Strömungsgleichrichter im Quer­ schnitt, Figure 3 cut. The built-in flow straightener in the cross,

Fig. 4 den eingebauten Strömungsgleichrichter zwischen dem Luftansaugrohr und dem Eintrittsrohr für die Verdichterturbine. Fig. 4 shows the built-in flow straightener between the air intake pipe and the inlet pipe for the compressor turbine.

Ein Strömungsgleichrichter 1 im Luftansaugrohr 2 einer druck­ beaufschlagten Brennkraftmaschine besteht aus einem mehrfach gebogenen federnden Blechstreifen, der wechselweise konvexe und konkave Bögen 3, 4 aufweist und zu einem mehrblättrigen Kleeblatt, z. B. gemäß Fig. 1 zu einem vierblättrigen Kleeblatt geformt ist. Das eine freie Ende 1a des Blechstreifens liegt auf dem konvexen Bogen 3a auf, von dem aus das andere freie Ende 1b des Blechstreifens bis etwa zum gegenüberliegenden konvexen Bogen 3b in leicht geschwungener konkaver Form reicht.A flow straightener 1 in the air intake pipe 2 of a pressurized internal combustion engine consists of a multi-curved resilient sheet metal strip, which alternately has convex and concave arches 3 , 4 and to a multi-leaf clover, z. B. is formed according to FIG. 1 to a four-leaf clover. One free end 1 a of the sheet metal strip lies on the convex arc 3 a, from which the other free end 1 b of the sheet metal strip extends approximately to the opposite convex arc 3 b in a slightly curved concave shape.

Durch die besondere Ausgestaltung dieses mehrfach gebogenen Blechstreifens ergeben sich im eingebauten Zustand die zur Gleichrichtung der Luftströmung dienenden Führungskanäle, von denen die außenliegenden mit 5, 6, 7 und 8 und die innenliegenden mit 9, 10 bezeichnet sind. Die Kanäle 9, 10 sind durch das freie Ende 1b des Blechstreifens gebildet, das als Trennwand wirkend den durch die Bögen gebildeten Innenraum aufteilt.Due to the special design of this multi-curved sheet metal strip, the guide channels used for rectifying the air flow result in the installed state, of which the outer ones are designated by 5, 6, 7 and 8 and the inner ones by 9, 10 . The channels 9 , 10 are formed by the free end 1 b of the sheet metal strip which, acting as a partition, divides the interior space formed by the arches.

Das Luftansaugrohr 2 ist gemäß Fig. 2 zur axialen Lagefixierung des Strömungsgleichrichters 1 mit einer Ausdrehung versehen, deren Durchmesser DI kleiner ist als der Durchmesser DII des Strömungsgleichrichters 1 in entspannter Form. Es kann aber auch bereits eine ringförmige Aussparung 11 im Luftansaugrohr 2 eingegossen sein. Bei der Montage wird der Strömungsgleich­ richter 2 unter Vorspannung in das Luftansaugrohr 1 gesteckt und rastet dort in die Aussparung 11 ein.The air intake pipe 2 is provided according to FIG. 2 for the axial position fixing of the flow straightener 1 with a recess whose diameter D I is smaller than the diameter D II of the flow straightener 1 in a relaxed form. However, an annular recess 11 can already be cast in the air intake pipe 2 . During assembly, the flow straightener 2 is inserted under prestress into the air intake pipe 1 and engages there in the recess 11 .

Um neben einer axialen Lagefixierung auch eine Fixierung des Strömungsgleichrichters 2 in Drehrichtung zu erhalten, sind anstelle einer ringförmigen Aussparung im Luftansaugrohr 1 in Umfangsrichtung gleichmäßig verteilte und den konvexen Bögen 3 des Blechstreifens angepaßte Taschen 12 vorgesehen, in die der Strömungsgleichrichter 1 bei der Montage axial- und drehfest eingeschnappt ist (Fig. 3).In order to obtain a fixation of the flow straightener 2 in the direction of rotation in addition to an axial position fixation, instead of an annular recess in the air intake pipe 1, pockets 12 are evenly distributed in the circumferential direction and adapted to the convex arches 3 of the sheet metal strip, into which the flow straightener 1 axially and snapped into place ( Fig. 3).

In Fig. 4 ist ein Luftansaugrohr 2 gezeigt, dessen Innendurch­ messer größer ist als derjenige des Eintrittsrohres 13 für die Verdichterturbine 14 des Abgasturboladers. Der Strömungs­ gleichrichter 1 befindet sich bei dieser Ausführung im wesent­ lichen im Luftansaugrohr 2. Das aus dem Luftansaugrohr 2 her­ ausragende freie Ende des Strömungsgleichrichters 1 liegt am Eintrittsrohr 13 an und ist somit in Richtung zur Verdichter­ turbine 14 fixiert. Luftansaugrohr 2 und Eintrittsrohr 13 sind durch einen Schlauch 15 mit Schlauchschellen 16 miteinander verspannt.In Fig. 4, an air intake pipe 2 is shown, whose inside diameter is larger than that of the inlet pipe 13 for the compressor turbine 14 of the exhaust gas turbocharger. The flow rectifier 1 is in this embodiment in wesent union in the air intake pipe 2nd The free end of the flow straightener 1 protruding from the air intake pipe 2 bears against the inlet pipe 13 and is thus fixed in the direction of the compressor turbine 14 . Air intake pipe 2 and inlet pipe 13 are clamped together by a hose 15 with hose clamps 16 .

Der federnde Blechstreifen kann auch die Gestalt eines Sterns oder einer Spirale oder eine ähnlich geometrische Form aufwei­ sen, die den Luftraum teilt. Diese Formen sind ebenfalls kostengünstig zu fertigen und zu montieren.The resilient metal strip can also have the shape of a star or a spiral or a similar geometric shape that divides the airspace. These shapes are also inexpensive to manufacture and assemble.

Der Strömungsgleichrichter 1 kann auch bereits in das Luftan­ saugrohr 2 mit eingegossen werden.The flow straightener 1 can also be cast into the air intake pipe 2 .
