In this version, as is generally the case with the use of pipe parts The disadvantage of sheet metal is that the thin ones are stitched into one another Sheet metal parts light; being able to ground out of round and then not allow themselves to be twisted against each other very much. There is also the There is a risk that the cables will adhere firmly to one another due to the formation of rust.

The task of the invention is to put the intake pipe under To avoid the disadvantages listed above in such a way that sit simple parts, a mutually reliable at any time Sehwenkbarlceit the body parts is guaranteed.

According to the invention, the object is achieved in that the pipe elbow and earpiece are constructed as plastic parts and the pipe elbow is preceded by a metal pipe that is permanently connected to it, preferably encapsulated with it, in the direction of flow.

With the use of plastic parts there is no risk that the hair pieces by being slightly rounded or by rust formation can no longer be rotated against each other as required. The disadvantageous property of many plastics, not very to be heat-resistant is due to the with it inextricably connected metal pipe bent forward. The one made of plastic Existing pipe elbow is now also in the winter position a sufficiently large distance from the hot exhaust, so that even after operation of the internal combustion engine at a standstill, if that The intake pipe is no longer cooled by the air flowing through it, ■ no inadmissibly high heating can occur.

In the following, the invention is based on one shown in the drawing

provided exemplary embodiment explained in more detail. In the drawing demonstrate:

Figure 1 shows an air filter attached to an internal combustion engine with an intake pipe according to the invention,

Figure 2 d # 35 Ässs ^ lwitfiltex- of Figure 1 in side view,

FIG. 5 shows a detail of the intake pipe in an enlarged illustration.

An internal combustion engine has an intake line 2 with a carburetor and an exhaust line 4. An air filter is attached to the carburetor, the intake pipe 6 of which is drawn from the horizontal brine production shown in dash-dotted lines, in which the intake opening is more in the cold air area »in the vertical winter position with suction opening very in. The exhaust line can be swiveled · The suction pipe 6 consists of a Sohratuck 7 rigidly attached to the air filter 5 and a Hobxkxüssser S * that can be swiveled ^{around the 1 Eohr axis}

Drill bit? and SohrkrüEaner 8 are made of plastic and pivotally connected to each other in some way. To the 2-ear elbow 8 lsi; a metal tube permanently connected to iJma 9 upstream ;. As can be seen from Figure 3, this is Metal pipe 9 is encapsulated in the goTrrlrrggaer 8, d.
