Description

Carter de filtrage de liquide de type gazole. Diesel type liquid filter housing.

L'invention concerne le filtrage de liquides de type gazole et ieur dégazage.The invention relates to the filtering of diesel-type liquids and their degassing.

Plus précisément, I'invention concerne un carter (ou cuve) de réception d'une cartouche de filtrage, pourvu d'un couvercle, d'une entrée de liquide et d'une sortie de liquide destinées à être raccordées respectivement à un réservoir et à une pompe, par exemple à une pompe à injection d'un moteur.More specifically, the invention relates to a housing (or tank) for receiving a filter cartridge, provided with a cover, a liquid inlet and a liquid outlet intended to be connected respectively to a reservoir and to a pump, for example to an injection pump of an engine.

La cartouche de filtrage vise à arrêter les particules en suspension dans le liquide.The filter cartridge aims to stop particles in suspension in the liquid.

Le réservoir contient de l'air et des gaz qui circulent avec le liquide et peuvent former des poches d'air et de gaz qui, si elles traversaient le milieu filtrant faute d'aménagement particulier, risqueraient de créer des incidents au niveau de la pompe, au démarrage ou en fonctionnement. C'est ainsi qu'on à déjà proposé, comme dans FR-A-2 693 663 et FR-A-2 684 894, de pourvoir les cartouches de filtrage de moyens de dégazage du liquide les traversant. II est fait ici référence aux cartouches réalisées au moyen de bandes de papier enroulées ou plissées en étoile autour d'un mandrin central, avec un tube de dégazage plongeant à l'intérieur du mandrin, qui communique avec la sortie du carter et qui est percé d'un ou plusieurs orifices, formant gicleurs de dégazage, assurant l'évacuation de l'air et de gaz mais sous forme de bulles petites et régulières, sans risque pour la pompe.The tank contains air and gases which circulate with the liquid and can form pockets of air and gas which, if they crossed the filtering medium for lack of particular arrangement, would risk creating incidents at the level of the pump. , at startup or during operation. Thus it has already been proposed, as in FR-A-2 693 663 and FR-A-2 684 894, to provide the filter cartridges with means for degassing the liquid passing through them. Reference is made here to the cartridges produced by means of strips of paper wound or pleated in a star around a central mandrel, with a degassing tube plunging inside the mandrel, which communicates with the outlet of the casing and which is pierced one or more orifices, forming degassing nozzles, ensuring the evacuation of air and gas but in the form of small and regular bubbles, without risk for the pump.

La solution d'une cartouche de filtrage à tube de dégazage intégré présente l'inconvénient de l'intégration du tube, tant au plan des coûts de fabrication qu'à celui des conditions de mise en oeuvre et de stockage.The solution of a filter cartridge with an integrated degassing tube has the disadvantage of integrating the tube, both in terms of manufacturing costs and in terms of processing and storage conditions.

Ainsi, la demanderesse propose son invention qui concerne un carter du type mentionné ci-dessus, caractérisé par le fait que du couvercle est solidaire un tube de dégazage qui communique avec la sortie de liquide et qui est percé d'au moins un orifice de dégazage. Thus, the applicant proposes its invention which relates to a casing of the type mentioned above, characterized in that the cover is integral with a degassing tube which communicates with the liquid outlet and which is pierced with at least one degassing orifice .

L'intérêt de la solution de l'invention, c'est son universalité, en ce sens que le carter peut recevoir indifféremment des cartouches de filtrage de n'importe quel type.The advantage of the solution of the invention is its universality, in the sense that the casing can indifferently receive filter cartridges of any type.

De préférence, le tube de dégazage et la sortie de liquide débouchent tous deux dans une poche du couvercle formée sous un bossage central.Preferably, the degassing tube and the liquid outlet both open into a pocket in the cover formed under a central boss.

On soulignera que quand, dans le carter de l'invention, il est fait usage d'une cartouche réalisée à partir d'une bande de papier filtre percée d'orifices de dégazage, comme enseigné dans FR-A-2 693 663, on évite l'accumulation d'air ou de gaz sur le papier et donc on évite tout risque d'aspiration brutale et excessive à travers les pores du papier, c'est-à-dire tout risque de calage. En d'autres termes, un papier filtre à orifices de dégazage évite de mettre hors service les gicleurs de dégazage du carter.It will be emphasized that when, in the housing of the invention, use is made of a cartridge produced from a strip of filter paper pierced with degassing orifices, as taught in FR-A-2 693 663, prevents the accumulation of air or gas on the paper and therefore avoids any risk of sudden and excessive suction through the pores of the paper, that is to say any risk of jamming. In other words, a filter paper with degassing orifices avoids putting the degassing nozzles of the crankcase out of service.

L'invention sera mieux comprise à l'aide de la description suivante d'une forme de réalisation préférée du carter de l'invention, en référence au dessin annexé, sur lequel - la figure 1 est une vue de dessus du carter et - la figure 2 est une vue en coupe axiale du carter, selon la ligne ll-ll de la figure 1.The invention will be better understood with the aid of the following description of a preferred embodiment of the casing of the invention, with reference to the appended drawing, in which - FIG. 1 is a top view of the casing and - the FIG. 2 is a view in axial section of the casing, along the line II-II of FIG. 1.

L'équipement du filtrage représenté sur les figures comporte un carter, ou cuve, 1, avec une entrée ici de gazole 2, en partie inférieure du carter et raccordée à un réservoir, un couvercle 3, une sortie de gazole 4, en partie supérieure et même reliée au couvercle 3 et raccordée à une pompe à injection d'un moteur, et un appendice de purge 5, avec une vis de purge 6. Dans l'exemple considéré, le carter 1 contient une cartouche de filtrage 7 comprenant une bande de papier 15 pliée en deux et enroulée autour d'un mandrin 8. L'élément filtrant 7 est contenu dans une enveloppe cyclindrique 9 et entre deux flasques annulaires percés 10, 11. Après introduction de l'élément filtrant, le carter 1 est refermé à l'aide du couvercle 3, avec interposition d'un joint annulaire 12 et à l'aide d'une bague de serrage 13.En fonctionnement, le gazole circule du bas vers le haut, selon la flèche 14, à travers d'abord le flasque inférieur 10, ensuite la papier 15 puis le flasque supérieur 11.The filtering equipment shown in the figures comprises a casing, or tank, 1, with a diesel inlet 2 here, in the lower part of the casing and connected to a tank, a cover 3, a diesel outlet 4, in the upper part and even connected to the cover 3 and connected to an injection pump of an engine, and a purge appendage 5, with a purge screw 6. In the example considered, the casing 1 contains a filter cartridge 7 comprising a band of paper 15 folded in half and wrapped around a mandrel 8. The filter element 7 is contained in a cylindrical envelope 9 and between two annular annular flanges 10, 11. After introduction of the filter element, the casing 1 is closed using the cover 3, with the interposition of an annular seal 12 and using a clamping ring 13.In operation, the diesel flows from the bottom to the top, according to arrow 14, through first the lower flange 10, then the paper 15 then the fl upper asc 11.

Du couvercle 3 est solidaire un tube de dégazage 16, ouvert vers le bas et débouchant dans une poche 17 du couvercle formée sous un bossage central 18. C'est dans la poche 17 que débouche la sortie de gazole 4.The degassing tube 16 is integral with the cover 3, open downward and opening into a pocket 17 of the cover formed under a central boss 18. It is in the pocket 17 that the diesel outlet 4 opens.

Sensiblement dans la zone 19 de raccordement du tube 16 au couvercle 3, un orifice 20 est percé (il pourrait y en avoir plusieurs), pour faire fonction de gicleur de dégazage.Significantly in the area 19 of connection of the tube 16 to the cover 3, an orifice 20 is drilled (there could be several), to act as a degassing nozzle.

En fonctionnement, le tube de dégazage 16 plonge à l'intérieur du mandrin 8.In operation, the degassing tube 16 plunges inside the mandrel 8.

Le gazole filtré par le papier 15, après traversée du flasque supérieur 11, circule vers le bas, le long de la paroi externe du tube 16 pour être aspiré à travers son ouverture inférieure 21, remonter à l'intérieur du tube 16, jusque dans la poche 17, avant d'être évacué par la sortie 4.The diesel filtered by the paper 15, after crossing the upper flange 11, flows down, along the outer wall of the tube 16 to be sucked through its lower opening 21, go back up inside the tube 16, as far as the bag 17, before being evacuated by the outlet 4.

Le gaz et l'air, qui sont remontés à travers l'élément filtrant 7 et temporairement stockés (22) entre le couvercle 3 et l'élément 7, sont évacués vers la sortie 4 à travers le gicleur 20 sous forme de bulles petites et régulières 23, sans risque pour la pompe.The gas and the air, which are brought up through the filter element 7 and temporarily stored (22) between the cover 3 and the element 7, are evacuated towards the outlet 4 through the nozzle 20 in the form of small bubbles and regular 23, without risk to the pump.

A la place de l'élément filtrant 7 à papier enroulé, le carter pourrait recevoir un élément d'un autre type, par exemple à papier plissé en étoile. C'est dans ce sens qu'on peut qualifier le carter à tube de dégazage intégré, qui vient d'être décrit, d'universel. In place of the filter element 7 with rolled paper, the casing could receive an element of another type, for example with paper pleated in a star. It is in this sense that the casing with integrated degassing tube, which has just been described, can be described as universal.
