Abstract

A filter (2) for fluid with a container (4) and several filter media, in particular a filter basket (42), a filter pocket and a battery of filter cartridges. The container has unique means (14) of receiving the filter media, so they can be used interchangeably inside the container The means of reception comprise a collar (14) extending radially from one end of the main part of the container. The collar is designed to receive means (48, 52, 54) of fixing each filter medium. The battery of filter cartridges comprise a base plate, a cover and a number of filter cartridges fixed to the base plate and the cover. The cover is designed to fix to the collar in the container and the battery has a means of gripping. The cartridges are stacked into several consecutive series and there is at least one intermediate plate fixed to the base plate and cover to separate two neighboring cartridges. The cartridges are annular and means of locating the cartridges are fixed to the base plate or the cover or, if there is one, the intermediate plate. These means of location extend into the internal volume of the annular cartridges. The container has an inlet (20) and an outlet (38) line. The fluid flows through these lines in a transverse direction, preferably perpendicular to a principal axis of the main part. The principal axis is vertical and the supply and/or outlet lines are mounted to pivot about this axis, extending horizontally. One or both line is fixed, for example by welding, to a secondary container (18) concentric to the main part and pivoting about the principal axis.

Description

La présente invention concerne un filtre pour fluide. De manière classique, un filtre pour fluide comprend un carter et un médium filtrant, qui assure la retenue des impuretés solides initialement présentes dans le fluide à épurer. The present invention relates to a filter for fluid. Typically, a fluid filter comprises a housing and a filter medium, which ensures the retention of solid impurities initially present in the fluid to be purified.

Un tel médium filtrant peut être un panier rigide, par exemple métallique, percé de trous au travers desquels s'écoule le fluide purifié. Ce panier permet une épuration grossière du fluide, en retenant les particules solides de dimensions élevées. Such a filtering medium may be a rigid basket, for example metallic, pierced with holes through which the purified fluid flows. This basket allows a rough purification of the fluid, retaining the solid particles of high dimensions.

I1 est également connu d'utiliser une poche filtrante, formée par un matériau souple, qui est par exemple un feutre aiguilleté, réalisé en viscose, polypropylène ou polyester. Cette poche est pourvue d'orifices de taille réduite, qui permettent la retenue des particules solides de taille moyenne. It is also known to use a filter bag, formed by a flexible material, which is for example a needle felt, made of viscose, polypropylene or polyester. This pocket is provided with orifices of reduced size, which allow the retention of the solid particles of average size.

On utilise enfin, en vue d'une épuration fine, des média filtrants formés par des cartouches, dont chacune est consti tuée par un noyau support, sur lequel est arrangé un bobinage d'un fil de coton ou de polypropylène. Ces cartouches assurent la retenue des particules solides de faible dimension. Finally, filtering media formed by cartridges, each of which is constituted by a support core, on which a winding of a cotton or polypropylene thread is arranged, is used for fine purification. These cartridges ensure the retention of small solid particles.

De manière classique, le carter du filtre comprend une partie principale, destinée à la réception d'un médium fil trant et qui est par exemple constituée par un fût vertical cylindrique. Ce carter est également pourvu de moyens d'amenée du fluide à épurer, ainsi que de moyens de sortie du fluide épuré. Ces moyens d'amenée et de sortie sont par exemple constitués par des conduits horizontaux, qui sont soudés sur le fût vertical. Conventionally, the filter housing comprises a main part, intended for receiving a medium trant wire and which is for example constituted by a cylindrical vertical shaft. This casing is also provided with means for supplying the fluid to be purified, as well as outlet means for the purified fluid. These supply and discharge means are for example constituted by horizontal ducts, which are welded to the vertical shaft.

L'invention vise à proposer un nouveau type de filtre pour fluide. A cet effet, elle a pour objet un filtre pour fluide comprenant un carter et plusieurs média filtrants, notamment un panier filtrant, une poche filtrante et une batterie de cartouches filtrantes, ledit carter étant pourvu de moyens uniques de réception desdits média filtrants, de sorte que ces média filtrants peuvent être utilisés, de façon interchangeable, à l'intérieur dudit carter. The aim of the invention is to propose a new type of fluid filter. For this purpose, it relates to a fluid filter comprising a housing and several filtering media, in particular a filter basket, a filter bag and a battery of filter cartridges, said casing being provided with unique means for receiving said filter media, so that that these filtering media can be used, interchangeably, inside said housing.

La figure 1 représente un filtre pour fluide, désigné dans son ensemble par la référence 2 et qui comprend un carter 4 de réception de plusieurs média filtrants, comme cela sera explicité ci-après. FIG. 1 represents a filter for fluid, designated as a whole by the reference 2 and which comprises a casing 4 for receiving several filtering media, as will be explained hereinafter.

Ce carter 4 comporte un fût principal 6, constituant une partie principale, qui est cylindrique et qui possède un axe principal A vertical. Ce fût 6 est prolongé, à son extrémité inférieure, par un fond 8, pourvu d'une purge 10. Ce fond repose sur trois pattes 12 soudées, espacées de façon régulière à 120 les unes par rapport aux autres. This housing 4 comprises a main shaft 6, constituting a main part, which is cylindrical and has a main axis A vertical. This barrel 6 is extended, at its lower end, by a bottom 8, provided with a purge 10. This bottom rests on three tabs 12 welded, regularly spaced at 120 relative to each other.

Le carter 4 comprend également une collerette radiale externe 14, soudée sur l'extrémité supérieure du fût 6, ainsi que des moyens d'amenée d'un fluide à épurer, qui sont désignés dans leur ensemble par la référence 16. Ces derniers comprennent un fût secondaire 18, concentrique au fût 6 et de diamètre supérieur à celui de ce dernier. Un conduit cylindri que 20, s'étendant perpendiculairement au fût 6, c'est-à-dire horizontalement, est soudé sur ce fût secondaire et débouche dans le volume intérieur de ce dernier. Ce conduit 20 est prolongé par une collerette d'extrémité 22, destinée à être raccordée à une arrivée non représentée d'un fluide à épurer. The casing 4 also comprises an outer radial flange 14, welded to the upper end of the barrel 6, as well as means for supplying a fluid to be purified, which are generally designated by the reference 16. These include a secondary shaft 18, concentric with the shaft 6 and of greater diameter than that of the latter. A cylindrical conduit 20, extending perpendicularly to the barrel 6, that is to say horizontally, is welded to the secondary drum and opens into the interior of the latter. This conduit 20 is extended by an end collar 22, intended to be connected to a not shown inlet of a fluid to be purified.

Le fût secondaire 18 repose, avec interposition d'un joint annulaire d'étanchéité 24, sur la collerette 14 et se trouve surmonté, avec interposition d'un joint annulaire d'étanchéité 26, par un couvercle 28 muni d'une poignée 30. La liaison entre la collerette 14, le fût secondaire 18 et le couvercle 28 est assurée par l'intermédiaire de tiges filetées 32, s'étendant à partir de la collerette 14 et traversant des orifices ménagés dans le couvercle 28. The secondary drum 18 rests, with the interposition of an annular seal 24, on the flange 14 and is surmounted, with the interposition of an annular sealing gasket 26, by a cover 28 provided with a handle 30. The connection between the flange 14, the secondary shaft 18 and the cover 28 is provided by means of threaded rods 32, extending from the flange 14 and passing through orifices formed in the cover 28.

L'extrémité de ces tiges filetées, dont une seule est représentée sur cette figure 1, reçoit un écrou de blocage 34. Il est possible, par action sur cet écrou 34, de désolidariser le fût secondaire 18 de la collerette 14, de manière à faire pivoter le fût secondaire 18, et donc le conduit d'amenée 20, autour de l'axe principal vertical A du fût principal 6. The end of these threaded rods, only one of which is shown in this FIG. 1, receives a locking nut 34. It is possible, by action on this nut 34, to separate the secondary shaft 18 from the collar 14, so as to rotate the secondary shaft 18, and thus the supply conduit 20, about the vertical main axis A of the main shaft 6.

Le carter 4 est pourvu de moyens de sortie du fluide épuré, désignés dans leur ensemble par la référence 36. Ils comprennent un conduit cylindrique 38 s'étendant perpendicu lairement à l'axe principal A, à savoir horizontalement, prolongé par une collerette 40 de raccordement à une conduite non représentée, d'évacuation du fluide épuré. The casing 4 is provided with means for discharging the purified fluid, generally designated by the reference 36. They comprise a cylindrical duct 38 extending perpendicularly to the main axis A, namely horizontally, extended by a collar 40 of connection to a pipe, not shown, for evacuation of the purified fluid.

On entend par direction selon laquelle s'étendent les conduits 20 et 38, la direction principale selon laquelle s'écoule le fluide au sein de ces conduits. The direction in which the ducts 20 and 38 extend is the direction in which the fluid flows in these ducts.

Le filtre 2 comporte, outre le carter 4, un médium filtrant qui est, dans l'exemple représenté, un panier filtrant 42 de type classique. The filter 2 comprises, in addition to the casing 4, a filter medium which is, in the example shown, a filter basket 42 of conventional type.

Ce panier 42 comprend un corps cylindrique 44 muni de perçages 46. Ce corps 44, qui est concentrique au fût principal 6, possède un diamètre inférieur à celui de ce dernier. I1 est prolongé, à sa partie supérieure, par un rebord radial 48 externe, reposant sur la collerette 14, avec interposition d'un joint annulaire d'étanchéité 50. Ce rebord 48 est pourvu de plusieurs orifices, dont seuls deux sont représentés sur cette figure 1, qui sont traversés par des tiges filetées 52 fixées sur la collerette 14. Ces tiges 52 reçoivent à l'extrémité opposée de la collerette 14, des écrous 54 permettant la solidarisation du panier 42 à la collerette 14 du carter 4. This basket 42 comprises a cylindrical body 44 provided with holes 46. This body 44, which is concentric with the main drum 6, has a diameter smaller than that of the latter. I1 is extended, at its upper part, by an outer radial rim 48, resting on the flange 14, with the interposition of an annular sealing gasket 50. This flange 48 is provided with several orifices, of which only two are represented on this 1, which are traversed by threaded rods 52 fixed to the collar 14. These rods 52 receive at the opposite end of the flange 14, nuts 54 for securing the basket 42 to the flange 14 of the housing 4.

L'écoulement d'un fluide dans le filtre est matérialisé par les flèches F. Ce fluide est tout d'abord admis dans les moyens d'amenée 16, puis pénètre dans le volume intérieur du corps 44 du panier 42, traverse les perçages 46, ce qui permet son épuration. Le fluide purifié est ensuite évacué par les moyens de sortie 36. The flow of a fluid in the filter is materialized by the arrows F. This fluid is first admitted into the supply means 16, then enters the interior of the body 44 of the basket 42, through the holes 46 , which allows its purification. The purified fluid is then evacuated by the outlet means 36.

Les figures 2 et 3 représentent le filtre 2, illustré à la figure 1, dans lequel le panier filtrant 42 a été remplacé par un autre médium filtrant, à savoir une poche filtrante 56, qui est aussi de construction classique. Figures 2 and 3 show the filter 2, illustrated in Figure 1, wherein the filter basket 42 has been replaced by another filter media, namely a filter bag 56, which is also of conventional construction.

Cette poche filtrante 56 est entourée par un panier- support 58, rigide et percé de trous de grandes dimensions. Ce panier 58 comporte un rebord radial externe 60, reposant sur une entretoise annulaire 61 en appui sur la collerette 14. La poche filtrante 56 est munie, à son extrémité ouverte, d'un bourrelet périphérique 62, qui repose lui-même sur la face supérieure du rebord 60. Il est prévu un organe de bridage de cette poche, désigné dans son ensemble par la référence 64. Cet organe 64 comprend une couronne annulaire 66, à partir de laquelle s'étendent radialement des pattes 68 délimitant des encoches 70. L'organe de bridage 64 est en outre pourvu d'une anse 72. This filter bag 56 is surrounded by a support basket 58, rigid and pierced with large holes. This basket 58 has an outer radial rim 60, resting on an annular spacer 61 resting on the collar 14. The filter bag 56 is provided at its open end with a peripheral bead 62, which itself rests on the face upper flange 60. There is provided a clamping member of this pocket, generally designated by reference 64. This member 64 comprises an annular ring 66, from which radially extend tabs 68 delimiting notches 70. The clamping member 64 is further provided with a handle 72.

Le montage de la poche 56 sur le carter 4 consiste à écraser le bourrelet 62 entre le rebord 60 et la couronne 66 de l'organe de bridage. On insère des tiges filetées 74, fixées sur la collerette 14, dans les encoches 70, avec interposition d'un écrou intermédiaire 76. La fixation de chaque patte sur la tige correspondante est assurée par un écrou supérieur 78. The mounting of the pocket 56 on the casing 4 consists of crushing the bead 62 between the flange 60 and the ring 66 of the clamping member. Threaded rods 74, fixed on the flange 14, are inserted into the notches 70, with the interposition of an intermediate nut 76. The fixing of each tab on the corresponding rod is ensured by an upper nut 78.

L'écoulement du fluide, admis dans le filtre muni de la poche filtrante 56, est matérialisé par les flèches F'. Ce fluide s'écoule dans le volume intérieur de la poche filtrante 56, puis passe au travers des orifices dont est munie cette dernière. Le fluide épuré traverse alors les orifices du panier-support 58 puis se trouve dirigé vers les moyens de sortie 36. The flow of the fluid, admitted into the filter provided with the filter bag 56, is indicated by the arrows F '. This fluid flows into the internal volume of the filter bag 56, then passes through the orifices of which it is provided. The purified fluid then passes through the orifices of the support basket 58 and is then directed towards the outlet means 36.

Les figures 4 et 5 illustrent le filtre 2 équipé d'un troisième médium filtrant, différent du panier 42 et de la poche 56. Figures 4 and 5 illustrate the filter 2 equipped with a third filter medium, different from the basket 42 and the pocket 56.

Ce troisième médium filtrant est constitué par une batterie de cartouches filtrantes, désignée dans son ensemble par la référence 80. Cette batterie comprend une plaque de base 82 représentée, vue de dessus, à la figure 5. Cette plaque 82 est concentrique au fût 6 et possède un diamètre inférieur à celui de ce dernier. Elle est pourvue de trois extensions radiales 84 qui entrent en contact avec la paroi intérieure de ce fût 6. Il existe donc des passages 86 délimités par la paroi intérieure du fût et par la bordure extérieure de la plaque de base, au niveau de la partie de plus faible diamètre de cette dernière. This third filter medium is constituted by a battery of filter cartridges, generally designated by the reference 80. This battery comprises a base plate 82 shown, seen from above, in FIG. 5. This plate 82 is concentric with the drum 6 and has a smaller diameter than the latter. It is provided with three radial extensions 84 which come into contact with the inner wall of this barrel 6. There are therefore passages 86 delimited by the inner wall of the barrel and by the outer edge of the base plate, at the level of the part. smaller diameter of the latter.

Cette plaque de base 82 est percée d'orifices périphéri ques 88, régulièrement répartis le long de la bordure exté rieure de cette plaque de base 82. Cette dernière est en outre munie d'une tige filetée 90 s'étendant verticalement, à partir du centre de cette plaque 82. This base plate 82 is pierced with peripheral orifices 88, regularly distributed along the outer edge of this base plate 82. The latter is furthermore provided with a threaded rod 90 extending vertically, starting from center of this plate 82.

La batterie 80 comprend également plusieurs plaques intermédiaires 92, qui possèdent une configuration globalement analogue à celle de la plaque de base 82. Chaque plaque intermédiaire est pourvue d'orifices périphériques, analogues à ceux 88, ainsi que d'un orifice central 96 dont les dimen sions transversales sont sensiblement supérieures à celle de la tige filetée 90. The battery 80 also comprises a plurality of intermediate plates 92, which have a configuration substantially similar to that of the base plate 82. Each intermediate plate is provided with peripheral orifices, similar to those 88, as well as a central orifice 96 whose The transverse dimensions are substantially greater than that of the threaded rod 90.

La batterie 80 inclut en outre un couvercle 98 cylindri que, de plus grand diamètre que le fût 6. Ce couvercle est percé d'orifices périphériques<B>100</B> et d'un orifice central 102, analogues respectivement à ceux 94 et 96 des plaques intermédiaires 92. La face supérieure du couvercle 98 est pourvue d'un étrier en forme de U, soudé sur le couvercle par l'extrémité de ses ailes. Cet étrier est surmonté d'un anneau de préhension 106. The battery 80 further includes a cylinder-shaped cover 98 which is larger in diameter than the barrel 6. This cover is pierced with peripheral orifices <B> 100 </ B> and a central orifice 102, respectively similar to those 94 and 96 intermediate plates 92. The upper face of the cover 98 is provided with a U-shaped stirrup welded to the cover by the end of its wings. This stirrup is surmounted by a gripping ring 106.

I1 est en outre prévu des guides 108 réalisés en une matière plastique élastique, telle que du polypropylène. Chaque guide 108 comprend un corps 110 cylindrique creux, à partir de la périphérie duquel s'étend un voile radial 112. Ces guides 108 sont assujettis au niveau des orifices périphé riques 88, 94, 100 ou des orifices centraux 96, 102. Dans le cas où il équipe une plaque intermédiaire 92, chaque guide 108B est bloqué par une rondelle annulaire élastique 113, rapportée sur la surface de la plaque opposée au voile l12. Cet agencement permet ainsi le guidage à la fois d'une cartouche supérieure et d'une cartouche inférieure, comme cela sera explicité dans ce qui suit. Il est à noter que les guides 108A montés sur la plaque de base 82 possèdent un fond fermé, à l'opposé du couvercle 98, afin d'empêcher tout passage de fluide. In addition, guides 108 made of an elastic plastic material, such as polypropylene, are provided. Each guide 108 comprises a hollow cylindrical body 110, from the periphery of which extends a radial web 112. These guides 108 are secured at the peripheral orifices 88, 94, 100 or the central orifices 96, 102. when it equips an intermediate plate 92, each guide 108B is blocked by an elastic ring washer 113, attached to the surface of the plate opposite the web 12. This arrangement thus makes it possible to guide both an upper cartridge and a lower cartridge, as will be explained in the following. It should be noted that the guides 108A mounted on the base plate 82 have a closed bottom, opposite the cover 98, to prevent any passage of fluid.

La batterie 80 comporte enfin des cartouches annulaires 114, de tout type connu. Ces cartouches possèdent un volume intérieur V cylindrique, dont le diamètre est voisin du diamètre extérieur du corps 110 des guides 108. The battery 80 finally comprises annular cartridges 114, of any known type. These cartridges have a cylindrical internal volume V whose diameter is close to the outside diameter of the body 110 of the guides 108.

Le montage de la batterie 80 de cartouches s'opère comme suit. On dispose tout d'abord les guides 108 au niveau des parois des orifices périphériques 88, 94, 100 ainsi que centraux 96, 102. Puis, on place une première série de cartou ches 114A sur les guides 108A de la plaque de base 82. Ces cartouches sont immobilisées par coincement de leurs parois intérieures autour du corps 110 de ces guides, ce qui assure le positionnement adéquat de ces cartouches. Puis, on rapporte une première plaque intermédiaire, pourvue de ses guides 108B. On dispose alors, de façon analogue, une deuxième série de cartouches 114B. On empile de la sorte plusieurs séries de cartouches, et on rapporte, sur la dernière de celles-ci, le couvercle 98 muni de ses guides 108C et d'un joint non repré senté. The assembly of the battery 80 of cartridges is carried out as follows. The guides 108 are firstly arranged at the walls of the peripheral orifices 88, 94, 100 and at the center 96, 102. Then, a first series of cartridges 114A is placed on the guides 108A of the base plate 82. These cartridges are immobilized by jamming their inner walls around the body 110 of these guides, which ensures the proper positioning of these cartridges. Then, there is reported a first intermediate plate, provided with its guides 108B. A second series of cartridges 114B is then similarly arranged. In this way, several series of cartridges are stacked, and the lid 98, with its guides 108C and a seal not shown, is reported on the last of these.

On solidarise ensuite mutuellement le couvercle, les plaques intermédiaires et la plaque de base, en vissant un écrou 116 sur l'extrémité libre de la tige filetée 90, faisant saillie au-delà de l'âme de l'étrier 104. L'anneau 106 consti tue alors un moyen de préhension unique pour l'ensemble de la batterie de cartouches 80 ainsi constituée. The lid, the intermediate plates and the base plate are then mutually secured by screwing a nut 116 onto the free end of the threaded rod 90, protruding beyond the core of the stirrup 104. The ring 106 then constitutes a unique gripping means for the entire battery of cartridges 80 thus formed.

Puis, on fait descendre cette batterie 80 dans le volume intérieur du fût 6, jusqu'à ce que le couvercle 98 repose, par sa périphérie extérieure, contre la paroi supérieure de la collerette 14. On fixe alors cette collerette à ce couvercle, grâce à des tiges filetées 118 s'étendant à partir de la collerette 14, de façon à traverser des orifices ménagés dans le couvercle, l'extrémité libre de ces tiges 118 coopérant avec des écrous 120. Des flèches F " matérialisent le passage du fluide dans le filtre 2 équipé de la batterie de la cartouche 80. I1 est à noter que, par rapport aux exemples décrits en référence aux figures 1 à 3, le fluide s'écoule en sens inverse, à savoir que le conduit 38 constitue une entrée du fluide, alors que le conduit 20 assure la sortie du fluide. Le fluide admis par le conduit 38 s'écoule au travers des passages 86, ces derniers constituant la seule voie d'écoulement possible pour le fluide, dans la mesure où les orifices périphérique 88 de la plaque de base 82 sont obturés par les guides 108A. Le fluide traverse ensuite de l'extérieur vers l'intérieur les cartouches 114, au travers desquelles il est épuré. Le fluide purifié s'écoule alors dans le volume intérieur V de ces cartouche et sort de la batterie 80 par l'intérieur du corps creux 110 des guides 108C disposés sur le couvercle 98. Le fluide purifié est enfin dirigé vers le conduit 38. Then, this battery 80 is lowered into the internal volume of the drum 6, until the cover 98 rests, by its outer periphery, against the upper wall of the flange 14. This flange is then fixed to this cover, thanks to threaded rods 118 extending from the flange 14, so as to pass through orifices in the lid, the free end of these rods 118 cooperating with nuts 120. Arrows F "materialize the passage of fluid in the filter 2 equipped with the battery of the cartridge 80. It should be noted that, compared with the examples described with reference to FIGS. 1 to 3, the fluid flows in the opposite direction, namely that the conduit 38 constitutes an input of fluid, while the conduit 20 ensures the fluid outlet.The fluid admitted through the conduit 38 flows through the passages 86, the latter constituting the only possible flow path for the fluid, to the extent where the peripheral openings 88 of the base plate 82 are closed by the guides 108A. The fluid then passes from the outside to the inside the cartridges 114, through which it is purified. The purified fluid then flows into the internal volume V of these cartridges and leaves the battery 80 through the interior of the hollow body 110 of the guides 108C disposed on the cover 98. The purified fluid is finally directed towards the conduit 38.

Il est avantageux de disposer d'un filtre comprenant un unique carter et de plusieurs média filtrants. Une telle solution est économique par comparaison avec l'art antérieur, dans lequel un carter de filtre donné ne peut recevoir qu'un seul type de médium filtrant. It is advantageous to have a filter comprising a single casing and several filtering media. Such a solution is economical compared to the prior art, in which a given filter housing can receive only one type of filter medium.

L'utilisation d'une batterie de cartouches filtrantes pourvue d'un unique moyen de préhension est également avanta geuse. En effet, un tel agencement est particulièrement commode et permet un montage aisé et rapide de cette batterie sur le carter du filtre. Ainsi, la batterie peut être assemblée à l'extérieur du filtre, puis introduite, en une seule opération, dans le volume intérieur du carter. Cela est à comparer avec l'art antérieur, dans lequel il est nécessaire de disposer les cartouches individuellement à l'intérieur du carter, ce qui induit une mise en oeuvre longue et fastidieu se, et de surcroit pénible en ce qui concerne les cartouches destinées à reposer vers la partie inférieure du carter du filtre. The use of a battery of filter cartridges provided with a single gripping means is also advantageous. Indeed, such an arrangement is particularly convenient and allows easy and fast mounting of this battery on the filter housing. Thus, the battery can be assembled outside the filter, and then introduced, in a single operation, into the interior of the housing. This is to be compared with the prior art, in which it is necessary to arrange the cartridges individually inside the housing, which induces a long and tedious implementation, and moreover painful with regard to the cartridges intended to rest towards the bottom of the filter housing.

Enfin, le fait de munir le carter d'une entrée et/ou d'une sortie orientables par rapport à la partie principale de ce carter permet de disposer cette entrée et/ou cette sortie en regard des conduits auxquels elles doivent être raccordées. De telles connexions peuvent alors être mises en oeuvre au moyen de tubulures de faible dimension, que l'on peut disposer de façon à peu près droite. Ceci est à comparer avec l'art antérieur, dans lequel, du fait de la position immuable de l'entrée et de la sortie par rapport à la partie principale du fût, il est nécessaire de faire appel à des tubulures de grande dimension, donc chères, encombrantes et délicates à monter, tubulures qu'il est également parfois nécessaire de cintrer, ce qui induit une usure prématurée.Finally, the fact of providing the housing with an inlet and / or an outlet that can be oriented with respect to the main part of this housing makes it possible to dispose this inlet and / or this outlet opposite the ducts to which they must be connected. Such connections can then be implemented by means of small size pipes, which can be arranged in a nearly straight manner. This is to be compared with the prior art, in which, due to the immutable position of the inlet and the outlet relative to the main part of the drum, it is necessary to use large pipes, so expensive, cumbersome and difficult to assemble, tubing that is also sometimes necessary to bend, which induces premature wear.
