- a filter insert uses a filter element which is identical to those of previously known filters such as in the document DE 43 40 094, which describes a filter that includes a filter element consisting of a main filter and a pre-filter.
- a filter element is also known from the document DE 195 09 825.
- Such a known filter element has a pre-filter which covers the surface of the filter element exposed to the air inlet of the main filter.
- this filter element When this filter element is placed in the sump of a present-day air filter, it is pressed together by the lid in the sump by pressing the prefilter against a rib which surrounds the sump at its lower part. The compression happens automatically, because this compression is going in the same direction as closing the lid.
- the closing movement of a filter insert is not the same: the lid is fixedly connected to the trough, and when the drawer is closed, it presses the filter element against the upper edge, which would be the cover in a modern filter; therefore, the prefilter is not pressed against the rib so that the water deposited on and in the prefilter is not discharged.

- the pre-filter protrudes, front in the lower position in the insertion direction
- housing is limited in front in the lower position by a rib, which a
- Support edge forms to the lower front edge of the prefilter locally komp ⁇
- the life of the filter is also improved, because because the main part of the filter does not get wet, it remains effective longer, as the retained by this body dust particles do not accumulate as sludge in the main body.
- the housing includes a Wasserammeiraum in which coming from the pre-filter Water collects, which is provided with a water outlet water collection chamber separated from the inlet space.
- the partition wall separating the inlet space for the air to be filtered from the area where the water droplets flowing along the walls or the lower surface of the prefilter arrives forms a water collecting space different from the inlet space, so that the air circulation in the inlet space does not Accumulating the water disturbs what happens in a quiet environment, which makes the separation of the water even more efficient.
- the main filter is limited on two opposite sides by the pre-filter, so that the filter element can be used in any orientation in the frame.
- the filter element is inserted into a frame which comes into the drawer, and the main filter is bounded at its upper edge by a peripheral seal, which partially protrudes beyond the contour of the main filter to support itself on a circumferential shoulder, which corresponds to that of the frame, and in built-in Condition against a support surface, which the Heilausströmhunt

- Insert 2 is inserted with a filter element 3.
- a filter element 3 In built-in
- the front side of the insert 2 is in the housing. 1
- the housing 1 consists of a lower part, the tub 11, and ei ⁇
- the housing 1 defines an inlet chamber
- the inlet chamber 13 is provided with a
- the motor is connected.
- the tub 11 includes a partition wall 111 which houses the inlet chamber
- the tub 11 forms a water collection chamber 15th
- the partition wall 111 is continued in the upper part with a support edge for the filter element 3 by a rib 112.
- the lower end of the Wasserammeiraums 15 terminates in a fitting 16, which forms the outlet for the deposited in the filter element 3 water.
- the inclusion of the filter element 3 in the housing 1 opens in the upper part in an opening; it is surrounded on its two sides by a rail 113 for the slot 2; At the installation point of the filter element 3, the lid 12 has a supporting edge 121 to realize a tight separation in cooperation with the seal 33 of the filter element 3, which separates the inlet chamber 13 from the outlet chamber 14.
- the flow direction of the air through the filter element 3 is indicated by the arrow A. The entrained air laden with dust and moisture passes from below against the lower surface of the filter to escape after passing through the filter 3 above again.
- the drawer 2 In the installed state and with the orientation shown in Figure 1, the drawer 2 is inclined forwardly; the leading edge of the filter element 3 opposite to that located adjacent to the handle 23 of the drawer 2 is in the lowermost position and forms the lower edge 321 which bears against the rib 112 which locally compresses the prefilter 32 when Inset 2 is introduced to favor the deposition of surface water.
- the aim of the rib 112 and the partition wall 111 of the tub 11 is to form two separate volumes of space:
- the first volume of space is the inlet chamber 13, in which the air to be filtered circulates; the air flow pushes the water against the prefilter 12 so that the water drops flow to the lowest point of the filter element due to gravity (arrow E),
- the second volume of space is the Wasserammeiraum 15, which allows the water to emerge from the pre-filter 32 and to flow into this volume 15 without being disturbed by the incoming air flow.
- the drawer 2 In the closed position, the drawer 2 is completely inserted into the housing 1; the handle 23 of the drawer 2 is attached with its edge 231 to the edge 114 of the housing opening 1 so that it can not come loose during vibration.
- the housing 1 is made of thermoplastic material and formed to simplify the production and in particular the mold of several parts and assembled later.
- Figure 2 shows the drawer 2 with the filter element 3, provided with its frame 4, wherein the filter element 3 is not yet completely in the slot 2.
- the drawer 2 is provided with two sides 21 so as to slide on the rails 113 of the housing 1 and with a rear handle 23.
- the front end of the drawer 2, which forms the lower end in the installed state, is open.
- the filter element 3 is housed in a frame 4, which encloses the circumference below the peripheral seal 33, which limits the top of the filter element 3.
- the two longitudinal sides 21 of the insert 2 have an L-shaped portion, the short length of the insert 2 serves as a support on the rails 113 of the housing 1.
- the front of the insert 2 has no side; the rear side is provided with a side 22 to which the handle 23 for pulling out or installation of the insert 2 is attached, as well as a peripheral seal and the edge serving as a fastening means of the insert 2 to the housing 1.
- the filter element 3 is inserted into the slot 2 by means of its frame 4; the frame 4 of the filter element 3 is only laterally through the Side 21 of the drawer 2 and allows a translational movement between the frame 4 and the drawer 2, for example from the position shown in Figure 2 to the position shown in Figure 1 for the installation of the filter 3 in the housing.
- the frame 4 is formed of four side parts 41, 42, the upper part of which forms a peripheral shoulder 43 ( Figure 1) to support the edge of the filter element 3 by means of the shoulder of the seal 33.
- the three sides 41 of the frame are provided in the lower part with the short L-piece 411 to support the filter element 3 on the periphery.
- the front side 42 of the frame which coincides with the lower part of the frame when installed, is unsupported without a short L-piece to leave the lower edge 321 of the prefilter 32 coming in contact with the rib 112 of the partition 111 ( Figure 2A).
- the filter element 3, shown without its frame 4, of a main filter 31 and a pre-filter 32 is formed.
- the lower surface 311 of the main filter 31 is covered by the pre-filter 32, which serves to retain coarse dust particles or water and to prevent the water in the air or the water polluting the moist air. to condense when entering the pre-filter, so that the water neither the interior of the pre-filter 32 and especially not the main filter 31 clogged.
- the pre-filter 32 consists of a fabric layer which covers the entire lower surface 311 of the main filter 31, that is, the entire surface through which air flows.
- the pre-filter 32 also covers the side 312 of the main filter 31, which is in the lowest position when the insert 2 is installed.
- the two opposite sides 312, 313 of the prefilter 32 are also still covered with the lower surface 311, so that the filter element 3 can be placed in the frame 4 and the drawer 2 with an orientation in both the one and the other direction, knowing that its rectangular shape does not allow it to be in the drawer 2 with a different orientation than in the direction D place.
- This orientation corresponds to the direction parallel to the plan of Figure 1 (the arrow D represents the longitudinal direction in Figures 1 to 3).
- the upper part 314 of the main filter 31 is surrounded by the clearly triangular circumferential seal 33, which is preferably made of polyurethane foam, and which protrudes at its base 331 beyond the contour of the main filter 31 to which it is attached then on the By supporting this, the peripheral seal 33 is compressed when the filter element 3 and the insert 2 are installed in the housing 1 ( Figure 1).
- the seal 33 is not compressed, but it is in Figure 1.
- This compression of the seal 33 is done by the insert 2: the filter element 3 is installed in the housing 1, wherein it may be partially through the drawer 2 is held in a position relative to the drawer 2, as shown in Figure 2; then pushes the drawer 2 between the rails 113 and the filter element 3 already in its position shown in Figure 1.
- the insert 2 has the function of a wedge, which raises the frame 4 to apply it to the peripheral seal 33 and partially press against the support edge 121 of the lid 12, wherein the tightness in relation to the cover 12 of the housing 1 is realized.
- This lifting of the frame 4 has no effect on either the main filter 31 or the pre-filter 32. In the latter case, only the lower edge is pressed against the rib 112 by the insertion of the insert 2.
- FIG. 4A shows the existing of its two parts housing, the tub 11 and the cover 12, which are assembled with not shown connecting means. In this figure you can see the rail 113 of the tub and the opening 114 through which the insert is inserted. All other elements have already been described above.
- Figure 4B shows a schematic view of the insert 2 with the filter 3, wherein the frame 4 is shown, which surrounds the filter 3 and supports it by means of the seal 33. This sectional view also shows the leading edge 321 of the prefilter 32.
