Definitions
- the invention relates to a support tube according to the preamble of claim 1 and a filter element according to the preamble of claim 8.
- Support tubes or filter elements of this type are known, for example from German Offenlegungsschrift 37 23 807.
- the object is achieved in that the support tube consists in particular of plastic and can be assembled from two essentially identical sub-elements, each sub-element having at least one inlet and outlet opening and having at least one radial and / or axial sealing area and at least one with the other sub-element communicating connection area.
- the provision of sealing surfaces on the partial elements made of plastic and their standardization reduce the number of necessary elements, so that cheaper products are therefore created.
- An advantageous development of the invention provides that the radial sealing area is essentially cylindrical. This cylindrical design ensures that, for example, a uniform fit is possible by consistently continuing the support tube geometry, for example the filter element on the support tube.
- the radial sealing area is conical. This has the advantage that due to the conical design when mounting the support tube in, for example the filter cartridge made of paper, a centering and a forced contact in the sealing area takes place.
- connection areas of the two sub-elements are designed as a snap connection. It proves to be particularly advantageous that no further assembly effort is required to connect these sub-elements.
- connection areas of the two sub-elements are designed as a snap-in connection.
- the creation of a secure connection of the two elements is particularly favorable here, so that the existence of the entire element is ensured.
- connection areas of the two sub-elements are designed as a bayonet connection. Similar to the snap connection, no additional assembly effort is necessary with this bayonet connection.
- the bayonet connection guarantees a controlled opening of the entire connection of both sub-elements in the event of disassembly.
- the two sub-elements are identical, so that they can be manufactured in a single tool, which leads to cost advantages. Furthermore, the object is achieved in that a support tube described in the introduction is used in a filter element.
- the use of support tube elements which are simple and inexpensive to produce and which suitably originate from a single tool and which, after installation in the filter element, also simultaneously perform a sealing function in the areas provided for this purpose is particularly favorable.
- Figure 1 shows a complete filter element in section
- Figure 2 a shows a detail of a bayonet-turn-snap connection
- FIG. 2 b shows a detailed illustration from FIG. 2 a
- FIG. 3 shows a complete filter element from identical part elements in the
- the filter element which is shown in Figure 1, consists of a support tube 2 and a paper element 10.
- the support tube 2 is composed of two sub-elements 3. Each of these sub-elements has radially, on its lateral surface distributed inlet openings 4 and an outlet opening 5, so that the actual filtration process takes place from the outside in.
- the paper element 10 which has a paper element termination 11, has in this embodiment that is removable, a inserted in the paper element seal 9. Both elements, paper element closure 11 and seal 9 have a sealing function in order to separate the clean side from the raw side.
- the two sub-elements 3 are used in such a way that the paper element 10 is not compressed. In this way, a reliable radial seal is formed between the support tube 2 and the paper element 10 in the radial sealing areas between the partial elements 3, which form the support tube 2.
- an axial sealing area 7, which can be designed as an axial disk seal.
- connection area 8 of the two partial elements 3 for example one partial element 3 has four snap tongues 12, the other partial element 3 has the corresponding latching projections 13.
- the snap tongues 12 then snap into the associated latching projections 13 of the other partial element 3 .
- each of the sub-elements 3 has z. B. two snap tongues and two locking projections, as shown in Figure 1, so that the sub-elements are absolutely identical and can be manufactured using a single tool.
- each sub-element 3 which has inlet openings 4 distributed on its outer surface, has at least one guide link 14 of a bayonet lock and at least one guide pin each of a bayonet lock in the connection area 8.
- the guide link 14 of one sub-element 3 communicates with the guide pin 15 of the other sub-element 3 in such a way that a releasable rotary snap connection is achieved.
- FIG. 2 b shows the bayonet connection with guide link 14 and guide pin 15 from FIG. 2 a in detail.
- Each of the sub-elements 3 has z. B. two snap tongues 12 and two locking projections 13, as shown in Figure 3, so that the sub-elements are absolutely identical and can be manufactured using a single tool.
- This in 3 filter element consists of a support tube 2 and a paper element 10.
- the support tube 2 is composed of two sub-elements 3.
- Each of these sub-elements has radially, on the lateral surface distributed inlet openings 4 and an outlet opening 5, so that the actual filtration process takes place from the outside in.
- the filtration process can also be operated from the inside out, in which case the inlet opening would become the outlet opening and vice versa.
- the paper element 10 which has a paper element closure 11
- the paper element closure 11 has a seal 9 inserted into the paper element closure.
- Both elements, paper element termination 11 and seal 9 have a sealing function in order to separate the clean from the raw side.
- the two sub-elements 3 are used in such a way that the paper element 10 is not compressed. In this way, a reliable radial seal is created between the support tube 2 and the paper element 10 in the radial sealing areas between the sub-elements 3, which form the support tube 2. which is designed as a lip seal.
