- FIG. 1 is a perspective view of a filter arrangement 1
- Section or the first segment 2 of the filter assembly 1 corresponds in
- a pipe and can be made of plastic or plastic
- tubular segment 2 is essentially a plastic tube 4A
- the cutouts are similar to those with a non-woven
- Filter material 4B are filled.
- first segment 2 connects a second segment 3, which has a
- the joint area is essentially formed from radial folds 18 and b forms in the manner of a Faltenge steering a bending-shaped part of the segment. 3
- outside air A flows, for example, through the filter material in the partial areas 4B of the first segment into the interior I of the filter arrangement 1 and flows out of the second segment 3 as purified, ie clean air RE out. There, for example, it can be tapped for the combustion of a fuel in an internal combustion engine.
- the segments 2, 3 di enen thus as a tubular base members, which can be added together to a total of a filter assembly 1 together.
- the flexible joint piece is made of plastic, for example, but may also be made of a filter material to achieve a filtering effect.
- the filter arrangement 1 is formed by way of example from six tubular segments 8, 9, 10, 2, 20 and 13.
- the tubular segments 8, 9, 10, 2, 20 and 13 form, for example, a part of a combustion air intake pipe for an engine, which is represented by the reference numeral 14.
- a straight segment 13 is connected to the air supply pipe 15 of the engine 14.
- a funnel-shaped fluid flow bundling device 7 is provided, which channels the raw air RO and allows it to flow into the first tubular section 8 or the first segment 8.
- a hose-shaped or hull-shaped filter element 16 is provided, which filters out particles that filter out of the raw air RO.
- the flow direction is shown by way of example in FIG. 2 in a first deployment variant of the filter arrangement 1 with the arrows n L1.
- the second segment 9 has a fold-joint-like section 17 and a straight section 21. It is therefore possible to achieve a curve or bend of the entire filter arrangement 1.
- the filter element 16 may be arranged in the axial direction in the interior of the components 2, 9, 10. This is flowed through according to the arrows L1. The filter element closes shortly before the component 12.
- component 10 is an impermeable plastic tube.
- the component 10 is a part of the overall filter element that extends inside an outwardly closed plastic tube. The flow is in this case from inside to outside towards plastic raw rwandung and from there into the section 2.
- the transverse folds 18 are provided at the connection areas and bent in the manner of a wrinkle joint.
- a straight intermediate section has longitudinal folds, whereby the filter surface of the segment 10 is enlarged.
- a fourth, straight tubular portion 2 for example made of a plastic material which is airtight, is provided.
- the air-tight portion 2 is coupled to a portion 1 2, which has a 20 Luftmassenmes water.
- the micromechanically executed air mass meter 20 measures the air mass conducted through the cylinder or the pipe 12.
- hot air mass flow meters are conceivable in which the air flow removes heat from a sensor element. The larger the corresponding air mass flow, the more energy must be used to keep the temperature of the corresponding sensor element constant. A corresponding heating current is proportional to the air mass flow and can be detected.
- the segment 9 has two tubular straight e region 21 A, 21 B, and a folded portion 17, which forms a hinge portion, so that in the manner of a fold joint flexibility entry. Further, a coupling means, for example, in the manner of a flange is provided at one end to e ine enable fluid- or airtight connection with another segment section.
- FIG. 4 shows a similar segment 9, which has a middle region 17, which is executed in the manner of a fold joint, and two coupling sections 22, which have convex protuberances 30, which serve as connecting means with corresponding concave indentations in further Tube segments serve, or are provided for centering the filter element in the housing tube.
- FIG. 5 shows a wide res embodiment for corresponding pipe segments, which are executed, for example, completely from a filter nonwoven material.
- FIG. 5A a longitudinal section along an axis of symmetry S is shown, wherein filter nonwoven material is folded in a zigzag shape and is glued in a tubular shape about an axis of symmetry S, for example with one another. This results in longitudinal folds 19, which are also stabilized in the figure 5A tabs or wraps 23, 24 of a nonwoven filter material.
- FIG. 5B shows a perspective view of the tubular section 10 or a corresponding opening section.
- FIG. 5B shows an insight into the interior I of the corresponding pipe segment 10.
- a corre sponding closure 6 can be formed from fluid-tight or air-tight or other fluid-permeable materials.
- FIG. 6 shows perspective views of further embodiments of pipe segments or tubular sections for a filter arrangement.
- a rohrf örmiges smooth segment 4B of filter nonwoven material is shown in Figure 6, which is inserted into a means of suitable transverse folds 28 flexibe l executed segment 25 and fixed, for example. This fixation can be done by gluing or other suitable measures.
- the tubular segment 25 is not only bendable, but also compressible and stretchable in length. This can be seen, for example, in FIG. 6B, which shows an opening of the tubular section 25 with its transverse folds 28.

- the tubular sections 2, 3, 27, 9 form an essential part of a combustion air intake pipe for the engine 14.
- the filter arrangement has the advantage that it can be assembled in a modular manner from various tubular segments, and that the available installation space is particularly efficient, in particular in an engine compartment can be used.
- the filtering surface of the tube or tube thus formed that is to say the surface portion of the tube wall which is made with a filtering material such as filter material, results from the required volume flow, the required dust capacity of the filter and the degree of separation.
- the degree of separation for particles to be filtered also depends on the filter medium used, for example felted plastic fiber fleece.
- connections between the respective tubular sections which can be used as base components can not be implemented detachably or can be separated in order to exchange individual tubular sections.
