Definitions
- the present invention relates to a device for cleaning liquid or gaseous media, having a cup-shaped or pot-shaped housing, having an exchangeable precipitating element situated in the device that separates a raw medium region and a clean medium region in the device from each other, having a medium inlet, opening into the raw medium region, for medium to be cleaned, having a medium outlet, going out from the clean medium region, for cleaned medium, and having a housing cover detachably connected to the housing by a connection, the housing having first circumferential connecting means and the housing cover having second circumferential connecting means fitting thereto, which can be brought into and out of engagement with each other through rotation relative to one another in the circumferential direction.
- the present invention relates to a precipitating element for the device.
- a device of the type named above and a precipitating element for the device are known from DE 87 14 656 U1.
- the precipitating element is a filter insert.
- the precipitating element On its end surface oriented toward the medium outlet, the precipitating element has an annular end plate with which it is plugged onto the medium outlet, fashioned as a pipe socket, and is in this way centered there.
- the precipitating element At its end remote from the medium outlet, the precipitating element has an end plate having a locking element situated at the upper side and having the shape of an undercut round recess, that, in the installed state, stands in detachable locking engagement with tongue-shaped locking elements on the inner side of the housing cover, as a result of which the precipitating element is also centered there.
- the centering of the precipitating element at its end remote from the medium outlet is not present, which can result in undesired movements of the precipitating element in this region both in the radial direction and in the circumferential direction, and thus to increased wear or damage at the precipitating element and/or at the housing and housing cover.
- an object therefore arises of providing a device of the type named above and a precipitating element for said device that avoids the named disadvantages, and in which a centering and fixing of the precipitating element is ensured even without the known locking elements.
- the present invention is intended to make it possible to achieve, as needed, further desired and positive properties with a low outlay for production and installation.
- the solution of the first part of the object, relating to the device, is achieved according to the present invention by a device of the type named above that is characterized in that the first connecting means or the second connecting means have at least one interruption of the connecting means, running in the axial direction of the connecting means, and that the precipitating element has at least one positioning arm that, in the installed state of the precipitating element and when the housing cover is connected to the housing, is received at least partly in the connecting means interruption in a position and orientation corresponding to the at least one connecting means interruption.
- the means for centering and fixing the precipitating element are placed in a region of the device not previously used for this purpose, namely in the region of the connection between the housing and housing cover of the device.
- the at least one positioning arm is automatically received in the connecting means interruption, and as a result is fixed in its position, which simultaneously brings about both the desired positioning and centering of the precipitating element and also its locking against an undesired rotation in the circumferential direction.
- the at least one positioning arm is also free, so that the precipitating element can then be removed unhindered from the device and can be replaced by a new, identical precipitating element having a positioning arm or positioning arms.
- attention must merely be paid to ensure that the at least one positioning arm comes to lie in fitting fashion in the associated connecting means interruption.
- the at least one connecting means interruption and the associated at least one positioning arm are here of course fashioned such that the rotation of the housing and the housing cover relative to one another required to produce and detach the connection between these two parts is not hindered.
- a plurality of connecting means interruptions are provided distributed over the circumference of the first connecting means or the second connecting means, and that the precipitating element has a plurality of positioning arms situated so as to fit correspondingly with the connecting means interruptions.
- the connecting means, interruptions of the first connecting means or of the second connecting means, and the positioning arms form a key-lock coding with one another.
- the connecting means, interruptions of the first connecting means or of the second connecting means, and the positioning arms are distributed irregularly in the circumferential direction, and/or that the connecting means interruptions of the first connecting means or of the second connecting means, have different widths from one another in the circumferential direction, and the positioning arms have a different width, fitting thereto, in the circumferential direction.
- the/each positioning arm is detachably lockable in the associated locking means interruption by interacting locking elements. In this way, an easily realizable pre-assembly of the precipitating element on the housing or on the housing cover is possible, and as a result, installation errors can be avoided to the greatest possible extent.
- the positioning arm or arms can be situated in different ways on the precipitating element, which itself can also have different realizations.
- a first realization in this regard is characterized in that the precipitating element has a hollow cylindrical basic shape having a precipitating material body, and two end plates covering this body at its ends, and that the/each positioning arm is connected to or made in one piece with the end plates of the precipitating element, or that the/each positioning arm is connected to the precipitating material body of the precipitating element in positionally fixed fashion in the circumferential and axial direction.
- the precipitating element is a precipitating material body having a hollow cylindrical basic shape and having a supporting body situated therein, and that the/each positioning arm is connected to or made in one piece with the supporting body of the precipitating element.
- the precipitating element can be realized with or without end plates.
- the precipitating element here, for example, can be a fiber separator or winding form that has no end plates and that, for example, can be used in an oil mist separator for the crankcase ventilation gas of an internal combustion engine.
- the precipitating element has a precipitating material body formed from two partial precipitating material bodies, each having a hollow cylindrical basic shape, and that two end faces, facing each other, of the two partial precipitating material bodies are connected to one another by an intermediate plate, and that the/each positioning arm is connected to, or made in one piece with, the intermediate plate of the precipitating element.
- the housing cover In the devices considered here, during operation the housing cover must be connected in medium-tight fashion to the housing, in order to reliably prevent an undesired or even dangerous exit of medium from the device.
- a seal that seals these from one another when the housing cover is connected to the housing.
- Standard practice is to install a fresh seal, e.g., in the form of an O-ring, as a separate individual part in a packaged fresh precipitating element provided as a replacement part, so that together with the precipitating element, the maintenance personnel also exchange the seal.
- the seal or a bearer that bears the seal, is connected to or made in one piece with at least one positioning arm of the precipitating element. In this way, it is advantageously ensured that the seal is also exchanged automatically every time the precipitating element is changed.
- the seal as a sealing ring, can be situated radially outwardly on the seal bearer or axially on the end face on the seal bearer.
- the seal can be molded onto the seal bearer or can be placed onto the seal bearer as a separately produced component.
- thermoplastic elastomer has properties that are suitable for a seal.
- connection between the housing and the housing cover having the first connecting means and the second connecting means is preferably formed through an axial overlap region of the housing and housing cover having interacting screw threadings or interacting bayonet connection elements.
- the device is preferably an oil filter or a fuel filter or an oil mist separator of an internal combustion engine of a motor vehicle.
- the advantageous properties of the device according to the present invention are put to particularly good use.
- the present invention also relates to a precipitating element for a device of the type described above, the device having a housing and a housing cover detachably connected to the housing, the housing having first circumferential connecting means and the housing cover having second circumferential connecting means fitting thereto, which can be brought into and out of engagement through rotation relative to one another in the circumferential direction, and the precipitating element being received exchangeably in the device.
- the present invention proposes that the precipitating element has at least one positioning arm that, in the installed state of the precipitating element and when the housing cover is connected to the housing, can be received in a connecting means interruption that is provided in the first connecting means or in the second connecting means, running in the axial direction of the connecting means.
- the precipitating element is thus matched to the associated device and is specifically made to fit thereto, in order to prevent the installation of unsuitable foreign precipitating elements in the device.
- the precipitating element has a plurality of positioning arms that are configured so as to fit correspondingly with a plurality of connecting means interruptions.
- the positioning arms are distributed irregularly in the circumferential direction and/or that the positioning arms have a different width from one another in the circumferential direction.
- the/each positioning arm usefully has locking elements that can be detachably locked with locking elements provided in the associated locking means interruption.
- the precipitating element has a hollow cylindrical basic shape having a precipitating material body and two end plates covering this body at its end faces, and the/each positioning arm is connected to or made in one piece with one of the end plates of the precipitating element, or the/each positioning arm is connected in positionally fixed fashion to the precipitating material body of the precipitating element in the circumferential and axial direction.
- a further embodiment in this regard proposes that the precipitating element has a precipitating material body having a hollow cylindrical basic shape and having a supporting body situated therein, and that the/each positioning arm is connected to or made in one piece with the supporting body of the precipitating element.
- the precipitating element can be realized with or without end plates and can be, for example, a fiber separator or winding form that does not have end plates and that, for example, can be used in an oil mist separator for the crankcase housing ventilation gas of an internal combustion engine.
- the precipitating element has a precipitating material body formed from two partial precipitating material bodies, each having a hollow cylindrical basic shape, two end faces, facing one another, of the two partial precipitating material bodies being connected to one another by an intermediate plate, and the/each positioning arm being connected to or made in one piece with the intermediate plate of the precipitating element.
- a seal or a seal bearer bearing a seal, be connected to or made in one piece with the at least one positioning arm, the housing and the housing cover being capable of being sealed from one another by the seal when connected to one another in the installed state of the precipitating element.
- seal for example as a sealing ring, can be situated radially externally on the seal bearer or axially on the end face on the seal bearer.
- the seal can be molded onto the seal bearer or can be placed onto the seal bearer as a separately manufactured component.
- the/each positioning arm, the seal bearer, and the seal are formed in one piece with one another from a thermoplastic elastomer.
- One of the end plates or the intermediate plate can also be included in this one-piece part.
- the precipitating element is preferably an oil filter insert of an oil filter or a fuel filter insert of a fuel filter or an oil mist separator insert of an oil mist separator of an internal combustion engine of a motor vehicle.
- the advantageous properties of the precipitating element are particularly well exploited.

Abstract
Description
- This application claims the benefit of the German patent application No. 20 2014 104 029.3 filed on Aug. 28, 2014, and of the German patent application No. 10 2015 103 619.3 filed on Mar. 12, 2015, the entire disclosures of which are incorporated herein by way of reference.
- The present invention relates to a device for cleaning liquid or gaseous media, having a cup-shaped or pot-shaped housing, having an exchangeable precipitating element situated in the device that separates a raw medium region and a clean medium region in the device from each other, having a medium inlet, opening into the raw medium region, for medium to be cleaned, having a medium outlet, going out from the clean medium region, for cleaned medium, and having a housing cover detachably connected to the housing by a connection, the housing having first circumferential connecting means and the housing cover having second circumferential connecting means fitting thereto, which can be brought into and out of engagement with each other through rotation relative to one another in the circumferential direction. Moreover, the present invention relates to a precipitating element for the device.
- A device of the type named above and a precipitating element for the device are known from DE 87 14 656 U1. Specifically, this document describes an oil filter for cleaning lubricant oil, in which the precipitating element is a filter insert. On its end surface oriented toward the medium outlet, the precipitating element has an annular end plate with which it is plugged onto the medium outlet, fashioned as a pipe socket, and is in this way centered there. At its end remote from the medium outlet, the precipitating element has an end plate having a locking element situated at the upper side and having the shape of an undercut round recess, that, in the installed state, stands in detachable locking engagement with tongue-shaped locking elements on the inner side of the housing cover, as a result of which the precipitating element is also centered there.
- However, in devices that are not intended to have, or cannot have, block elements of the type described above on the precipitating element and on the housing cover, the centering of the precipitating element at its end remote from the medium outlet is not present, which can result in undesired movements of the precipitating element in this region both in the radial direction and in the circumferential direction, and thus to increased wear or damage at the precipitating element and/or at the housing and housing cover.
- For the present invention, an object therefore arises of providing a device of the type named above and a precipitating element for said device that avoids the named disadvantages, and in which a centering and fixing of the precipitating element is ensured even without the known locking elements. In addition, the present invention is intended to make it possible to achieve, as needed, further desired and positive properties with a low outlay for production and installation.
- The solution of the first part of the object, relating to the device, is achieved according to the present invention by a device of the type named above that is characterized in that the first connecting means or the second connecting means have at least one interruption of the connecting means, running in the axial direction of the connecting means, and that the precipitating element has at least one positioning arm that, in the installed state of the precipitating element and when the housing cover is connected to the housing, is received at least partly in the connecting means interruption in a position and orientation corresponding to the at least one connecting means interruption.
- According to the present invention, the means for centering and fixing the precipitating element are placed in a region of the device not previously used for this purpose, namely in the region of the connection between the housing and housing cover of the device. In this way, it is advantageously achieved that when the housing cover is connected to the housing the at least one positioning arm is automatically received in the connecting means interruption, and as a result is fixed in its position, which simultaneously brings about both the desired positioning and centering of the precipitating element and also its locking against an undesired rotation in the circumferential direction. If, during maintenance, the connection between the housing and the housing cover is detached, then at the same time the at least one positioning arm is also free, so that the precipitating element can then be removed unhindered from the device and can be replaced by a new, identical precipitating element having a positioning arm or positioning arms. When installing the precipitating element, attention must merely be paid to ensure that the at least one positioning arm comes to lie in fitting fashion in the associated connecting means interruption. The at least one connecting means interruption and the associated at least one positioning arm are here of course fashioned such that the rotation of the housing and the housing cover relative to one another required to produce and detach the connection between these two parts is not hindered.
- In particular, for the purpose of a favorable distribution of forces, it is preferably provided that a plurality of connecting means interruptions are provided distributed over the circumference of the first connecting means or the second connecting means, and that the precipitating element has a plurality of positioning arms situated so as to fit correspondingly with the connecting means interruptions.
- In order to prevent, as completely as possible, installation of an unsuitable precipitating element in the device, and functional disturbances caused by this, it is proposed that the connecting means, interruptions of the first connecting means or of the second connecting means, and the positioning arms, form a key-lock coding with one another.
- Preferably, for the realization of this key-lock coding, it is provided that the connecting means, interruptions of the first connecting means or of the second connecting means, and the positioning arms, are distributed irregularly in the circumferential direction, and/or that the connecting means interruptions of the first connecting means or of the second connecting means, have different widths from one another in the circumferential direction, and the positioning arms have a different width, fitting thereto, in the circumferential direction.
- In order to facilitate the assembly of the device, a development of the device provides that the/each positioning arm is detachably lockable in the associated locking means interruption by interacting locking elements. In this way, an easily realizable pre-assembly of the precipitating element on the housing or on the housing cover is possible, and as a result, installation errors can be avoided to the greatest possible extent.
- The positioning arm or arms can be situated in different ways on the precipitating element, which itself can also have different realizations.
- A first realization in this regard is characterized in that the precipitating element has a hollow cylindrical basic shape having a precipitating material body, and two end plates covering this body at its ends, and that the/each positioning arm is connected to or made in one piece with the end plates of the precipitating element, or that the/each positioning arm is connected to the precipitating material body of the precipitating element in positionally fixed fashion in the circumferential and axial direction.
- A further realization in this regard proposes that the precipitating element is a precipitating material body having a hollow cylindrical basic shape and having a supporting body situated therein, and that the/each positioning arm is connected to or made in one piece with the supporting body of the precipitating element. In this embodiment, the precipitating element can be realized with or without end plates. Thus, the precipitating element here, for example, can be a fiber separator or winding form that has no end plates and that, for example, can be used in an oil mist separator for the crankcase ventilation gas of an internal combustion engine.
- According to a third realization in this regard, it is provided that the precipitating element has a precipitating material body formed from two partial precipitating material bodies, each having a hollow cylindrical basic shape, and that two end faces, facing each other, of the two partial precipitating material bodies are connected to one another by an intermediate plate, and that the/each positioning arm is connected to, or made in one piece with, the intermediate plate of the precipitating element.
- In the devices considered here, during operation the housing cover must be connected in medium-tight fashion to the housing, in order to reliably prevent an undesired or even dangerous exit of medium from the device. For this purpose, between the housing and housing cover there is situated a seal that seals these from one another when the housing cover is connected to the housing. In order to ensure tightness even after maintenance, it is usual, or even prescribed, to replace the seal between the housing and housing cover during each maintenance session. Standard practice is to install a fresh seal, e.g., in the form of an O-ring, as a separate individual part in a packaged fresh precipitating element provided as a replacement part, so that together with the precipitating element, the maintenance personnel also exchange the seal. However, in practice it occurs relatively frequently that, due to lack of attention or lack of knowledge, the maintenance personnel replace only the precipitating element but not the seal, or do not correctly install the fresh seal. In order to prevent this, according to the present invention it is provided that the seal, or a bearer that bears the seal, is connected to or made in one piece with at least one positioning arm of the precipitating element. In this way, it is advantageously ensured that the seal is also exchanged automatically every time the precipitating element is changed.
- The seal, as a sealing ring, can be situated radially outwardly on the seal bearer or axially on the end face on the seal bearer.
- Alternatively, the seal can be molded onto the seal bearer or can be placed onto the seal bearer as a separately produced component.
- In addition, there is the possibility that the/each positioning arm, the seal bearer, and the seal are made in one piece with each other from a thermoplastic elastomer. The thermoplastic elastomer has properties that are suitable for a seal.
- In the device according to the present invention, the connection between the housing and the housing cover having the first connecting means and the second connecting means is preferably formed through an axial overlap region of the housing and housing cover having interacting screw threadings or interacting bayonet connection elements.
- Finally, the device is preferably an oil filter or a fuel filter or an oil mist separator of an internal combustion engine of a motor vehicle. In these concrete embodiments and uses, the advantageous properties of the device according to the present invention are put to particularly good use.
- Besides the device, the present invention also relates to a precipitating element for a device of the type described above, the device having a housing and a housing cover detachably connected to the housing, the housing having first circumferential connecting means and the housing cover having second circumferential connecting means fitting thereto, which can be brought into and out of engagement through rotation relative to one another in the circumferential direction, and the precipitating element being received exchangeably in the device.
- In order to achieve the second part of the object of the invention, relating to the precipitating element, the present invention proposes that the precipitating element has at least one positioning arm that, in the installed state of the precipitating element and when the housing cover is connected to the housing, can be received in a connecting means interruption that is provided in the first connecting means or in the second connecting means, running in the axial direction of the connecting means. The precipitating element is thus matched to the associated device and is specifically made to fit thereto, in order to prevent the installation of unsuitable foreign precipitating elements in the device.
- Preferably, the precipitating element has a plurality of positioning arms that are configured so as to fit correspondingly with a plurality of connecting means interruptions.
- In order to enable a key-lock coding between the precipitating element and the rest of the device, it is provided that the positioning arms are distributed irregularly in the circumferential direction and/or that the positioning arms have a different width from one another in the circumferential direction.
- In order to make it possible to easily pre-mount the precipitating element on the housing or on the housing cover, the/each positioning arm usefully has locking elements that can be detachably locked with locking elements provided in the associated locking means interruption.
- In a development, the precipitating element has a hollow cylindrical basic shape having a precipitating material body and two end plates covering this body at its end faces, and the/each positioning arm is connected to or made in one piece with one of the end plates of the precipitating element, or the/each positioning arm is connected in positionally fixed fashion to the precipitating material body of the precipitating element in the circumferential and axial direction.
- A further embodiment in this regard proposes that the precipitating element has a precipitating material body having a hollow cylindrical basic shape and having a supporting body situated therein, and that the/each positioning arm is connected to or made in one piece with the supporting body of the precipitating element. In this embodiment, the precipitating element can be realized with or without end plates and can be, for example, a fiber separator or winding form that does not have end plates and that, for example, can be used in an oil mist separator for the crankcase housing ventilation gas of an internal combustion engine.
- In a further alternative, the precipitating element has a precipitating material body formed from two partial precipitating material bodies, each having a hollow cylindrical basic shape, two end faces, facing one another, of the two partial precipitating material bodies being connected to one another by an intermediate plate, and the/each positioning arm being connected to or made in one piece with the intermediate plate of the precipitating element.
- In order to obtain an additional use of the precipitating element, it is proposed that a seal, or a seal bearer bearing a seal, be connected to or made in one piece with the at least one positioning arm, the housing and the housing cover being capable of being sealed from one another by the seal when connected to one another in the installed state of the precipitating element.
- Here the seal, for example as a sealing ring, can be situated radially externally on the seal bearer or axially on the end face on the seal bearer.
- Alternatively, the seal can be molded onto the seal bearer or can be placed onto the seal bearer as a separately manufactured component.
- There is also the possibility that the/each positioning arm, the seal bearer, and the seal are formed in one piece with one another from a thermoplastic elastomer. One of the end plates or the intermediate plate can also be included in this one-piece part.
- Finally, the precipitating element is preferably an oil filter insert of an oil filter or a fuel filter insert of a fuel filter or an oil mist separator insert of an oil mist separator of an internal combustion engine of a motor vehicle. In these concrete embodiments and uses, the advantageous properties of the precipitating element are particularly well exploited.

FIG. 1 of the drawing shows afirst device 1 for cleaning liquid or gaseous media, such as lubricant oil, fuel, or crankcase ventilation gas of an internal combustion engine, in longitudinal section.Device 1 has a cup-shapedhousing 10 that is sealed at its top side by ahousing cover 11.Housing 10 andhousing cover 11 are detachably connected to one another by aconnection 2 made up of first connectingmeans 20 onhousing 10 and second connecting means 21 onhousing cover 11. Concretely, hereconnection 2 is a screw connection. For the seal betweenhousing 10 andhousing cover 11, when they are connected to one another, acircumferential seal 5 is situated between them that lies in axially sealing fashion between a lower edge ofhousing cover 11 and a sealingcollar 16 ofhousing 10. In this exemplary embodiment,seal 5 is a separate individual part. - In
housing 10, a precipitatingelement 3 is exchangeably situated, which element is made up of a precipitatingmaterial body 30 and anupper end plate 31 and alower end plate 32 that enclose precipitatingmaterial body 30 at the end faces. Precipitatingelement 3 is plugged onto a pipe socket-shapedmedium outlet 15, via a central perforation inlower end plate 32. Radially externally frommedium outlet 15, in the floor ofhousing 10 there is provided amedium inlet 12 that opens into a rawmedium region 13 radially outside precipitatingelement 3. A cleanmedium region 14 is situated radially inward from precipitatingmaterial body 30. - Here, a plurality of
positioning arms 4 are made in one piece withupper end plate 30, of which one is visible at left inFIG. 1 .Positioning arm 4 goes out from the radially external edge ofupper end plate 31, and runs first obliquely outward and then vertically downward. - As is shown in
FIG. 1 and in the enlarged detail inFIG. 1a , eachpositioning arm 4 runs through a connecting meansinterruption 23 in second connecting means 21 onhousing cover 11. Afree end 40 ofpositioning arms 4 is here situated at a distance aboveseal 5 in connectingmeans interruption 23. Via positioningarms 4, precipitatingelement 3 is centered insidedevice 1 and is fixed in rotationally fixed fashion in the circumferential direction. -
FIG. 2 showsdevice 1 ofFIG. 1 in a cross-section along sectional line II-II inFIG. 1 . Radially outwardly,first housing cover 11 is sectioned. Radially inwardly therefrom, there runs circumferential wall ofhousing 10. Between housing 10 andhousing cover 11 is situatedscrew connection 2. At locations distributed uniformly around the circumference ofdevice 1, there are situated respective connectingmeans interruptions 23, through each of which arespective positioning arm 4 runs. - The configuration of connecting
means interruption 23 and ofpositioning arms 4 can be varied within broad limits, and can advantageously be used to form a key-lock coding in order to permit only particular,suitable precipitating elements 3 to be installed indevice 1. - Radially inward from the circumferential wall of
housing 10 there is situated rawmedium region 13, followed, further radially inward, by precipitatingmaterial body 13 of precipitatingelement 3. At left inFIG. 2 , a small part ofmedium inlet 12 is still visible radially outside precipitatingelement 3. In the center inFIG. 2 , cleanmedium region 14 is situated in the interior of precipitatingelement 3, andmedium outlet 15 is in the background.FIG. 2 illustrates particularly clearly that here precipitatingelement 3 is received indevice 1 in rotationally fixed fashion and is centered therein. -
FIG. 3 shows asecond device 1, again in longitudinal section. In thisdevice 1 as well, a plurality ofpositioning arms 4 are provided, distributed around the circumference, of which one is visible at the right inFIG. 3 . Positioningarms 4 are here fashioned in one piece with abearer ring 41 that is fixedly attached on the outer circumference of precipitatingmaterial body 30 in the circumferential direction and in the axial direction, in particular by gluing or welding. Positioningarms 4 run through a connecting meansinterruption 22 that is fashioned in first connectingmeans 20 onhousing 10, as is visible at top right inFIG. 3 . - On the radial outer end of positioning
arms 4, these arms go over in one piece into aseal bearer 50 on whose downward-oriented side, in the axial direction, there is situated aseal 5 in the form of a sealing ring, which is, for example, molded or glued on. In this exemplary embodiment,seal 5 is thus an integral component of precipitatingelement 3, so that when precipitatingelement 3 is exchanged in the context of maintenance ofdevice 1,seal 5 is automatically also changed along with it and renewed while being necessarily correctly positioned. - In its further parts,
device 1 corresponds to the exemplary embodiment described above, to whose description reference is accordingly made. -
FIG. 4 showsdevice 1 ofFIG. 3 in cross-section according to the sectional line B-B inFIG. 3 ; here it can be seen that in this exemplary embodiment, a total of fourpositioning arms 4 are provided distributed around the circumference. Eachpositioning arm 4 runs through one of the connecting meansinterruption 22 inhousing 10. Radially inwardly, positioningarms 4 are made in one piece withbearer ring 41, which in turn is fixedly attached on the outer circumference of precipitatingmaterial body 30. Radially outwardly, positioningarms 4 go over in one piece intoseal bearer 50. Radially outwardly fromseal bearer 50,housing cover 11 is sectioned. Radially inwardly fromseal bearer 50, the section runs throughhousing 10, and in the center ofFIG. 4 medium outlet 15 can be seen in the background. -

In this example, connecting meansinterruptions 22 extend over the entire thickness of the material ofhousing 10; alternatively, connecting meansinterruptions 22 can also be realized as grooves extending, from the outside, only over a part of the material thickness ofhousing 10. Below connectingmeans 20, sealingcollar 16 extends outward in the radial direction, going out from the circumferential wall ofhousing 10. -
FIG. 8 shows a third device, again in longitudinal section. The realization of positioningarms 4 havingbearing ring 41,seal bearer 50, andseal 5 corresponds to the example described above. Differing here is the configuration ofpositioning arms 4. InFIG. 8 , these arms are situated further down, in the axial direction, on precipitatingmaterial body 30 of precipitatingelement 3, corresponding to the smaller height ofhousing 10 and the larger height ofhousing cover 11, so that positioningarms 4 come to be situated in a fitting manner at the height of the axial region of overlap ofhousing 10 andhousing cover 11. With regard to the further individual parts inFIG. 8 , reference is made to the description of the preceding exemplary embodiment. -
FIG. 9 showsdevice 1 ofFIG. 8 in cross-section according to the sectional line IX-IX inFIG. 8 .
