Description

La présente invention concerne un dispositif de régulation de la phase liquide d'un circuit de refroidissement d'un moteur thermique, notamment pour véhicule automobile.The present invention relates to a device for regulating the liquid phase of a cooling circuit of a heat engine, especially for a motor vehicle.

Elle concerne plus particulièrement un dispositif de régulation du type comprenant d'une part, une enveloppe de révolution positionnable sur le circuit de refroidissement, généralement entre la sortie de la culasse et/ou du radiateur du moteur et l'entrée du moteur, cette enveloppe de révolution, formée par deux demi-coquilles assemblées par un plan de joint, délimitant une enceinte fermée équipée au moins d'une entrée et d'une sortie de fluide de refroidissement, d'autre part, au moins une pièce de liaison pour la fixation de l'enveloppe au véhicule, ladite enveloppe comprenant au moins un organe de liaison réalisé d'une seule pièce avec ladite enveloppe, cet organe de liaison étant apte à venir en prise avec un organe de liaison complémentaire porté par ladite pièce de liaison à l'état raccordé de la pièce de liaison à l'enveloppe.It relates more particularly to a type of control device comprising on the one hand, a revolution envelope positionable on the cooling circuit, generally between the output of the cylinder head and / or the radiator of the engine and the engine inlet, this envelope of revolution, formed by two half-shells assembled by a joint plane, delimiting a closed chamber equipped at least with an inlet and a cooling fluid outlet, on the other hand, at least one connecting piece for the fixing the envelope to the vehicle, said envelope comprising at least one connecting member made in one piece with said envelope, said connecting member being adapted to engage a complementary connecting member carried by said connecting piece to the connected state of the connecting piece to the envelope.

De tels dispositifs sont bien connus à ceux versés dans cet art comme l'illustre en particulier le brevet français FR-2.890.109 . Le dégazage du liquide de refroidissement d'un moteur thermique est une action indispensable au bon fonctionnement du circuit de refroidissement dans lequel le liquide de refroidissement circule. Le dispositif de régulation assure donc la séparation des gaz, en particulier de l'air qui se trouve dans le liquide et dont la présence dans le circuit de refroidissement est néfaste pour son bon fonctionnement.Such devices are well known to those skilled in the art as illustrated in particular by the French patent FR-2890109 . The degassing of the coolant of a heat engine is an essential action for the proper functioning of the cooling circuit in which the coolant circulates. The regulating device thus ensures the separation of the gases, in particular of the air which is in the liquid and whose presence in the cooling circuit is detrimental to its proper functioning.

Un tel dispositif joue également le rôle de réservoir permettant ainsi de compenser les éventuelles pertes par micro-fuites du circuit de refroidissement. Il est également utilisé pour réaliser le remplissage et la mise à niveau du circuit en fluide de refroidissement. De plus en plus, il est nécessaire qu'une même boîte de dégazage puisse s'adapter à plusieurs types de véhicules. Or, en général, le volume laissé libre dans le compartiment moteur pour la réception du dispositif de régulation est réduit de sorte que l'emplacement des entrée et sortie et des moyens de fixation à l'intérieur de l'emplacement réservé au dispositif est imposé. Il en résulte qu'à un véhicule ne correspond qu'un seul type de dispositif de régulation.Such a device also acts as a reservoir thus making it possible to compensate for any losses by micro-leaks from the cooling circuit. It is also used for filling and leveling the cooling fluid circuit. More and more, it is necessary that same degassing box can adapt to several types of vehicles. However, in general, the volume left free in the engine compartment for the reception of the regulating device is reduced so that the location of the entry and exit and fastening means inside the location reserved for the device is imposed. . As a result, a vehicle only corresponds to one type of regulating device.

Il est également connu à travers le brevet FR-2.899.185 un dispositif de régulation dont l'enveloppe comporte une pluralité d'organes de liaison aptes à venir en prise avec des organes de liaison complémentaires ménagés dans un réservoir faisant office de pièce de liaison de l'enveloppe au véhicule. Les organes de liaison de l'enveloppe sont ménagés dans un plan radial orthogonal au plan de joint des demi-coquilles de sorte qu'ils occupent une grande partie de la surface des demi-coquilles et limitent les possibilités de positionnement des entrée, sortie ou autre élément de l'enveloppe. En outre, ils obligent la pièce de liaison à venir épouser l'enveloppe sur toute sa hauteur. La pièce de liaison forme alors un obstacle empêchant tout déplacement relatif à rotation de l'enveloppe et de la pièce de liaison lorsque l'enveloppe est équipée d'une entrée ou sortie radiale comme cela est le cas fréquemment. En outre, le raccordement de l'enveloppe à la pièce de liaison est difficile car l'enveloppe doit arriver à pénétrer dans la cavité circulaire ménagée dans la pièce de liaison. Enfin et comme l'illustre le brevet FR-2.899.185 , malgré la présence de plusieurs organes de liaison sur l'enveloppe, l'enveloppe ne présente qu'une seule position de raccordement à la pièce de liaison.He is also known through the patent FR-2899185 a control device whose envelope comprises a plurality of connecting members adapted to engage with complementary connecting members formed in a reservoir acting as connecting part of the envelope to the vehicle. The connecting members of the envelope are formed in a radial plane orthogonal to the joint plane of the half-shells so that they occupy a large part of the surface of the half-shells and limit the positioning possibilities of the inlet, outlet or other element of the envelope. In addition, they force the connecting piece to come and marry the envelope over its entire height. The connecting piece then forms an obstacle preventing any relative rotational movement of the envelope and the connecting piece when the envelope is equipped with a radial inlet or outlet as is the case frequently. In addition, the connection of the envelope to the connecting piece is difficult because the envelope must be able to penetrate into the circular cavity formed in the connecting piece. Finally and as illustrated by the patent FR-2899185 , despite the presence of several connecting members on the casing, the casing has only one connection position to the connecting piece.

Un but de la présente invention est donc de proposer un dispositif de régulation du type précité, dit universel, dont la conception permet de modifier aisément le positionnement relatif des entrée, sortie et des moyens de fixation du dispositif sans nuire aux performances du dispositif en matière de dégazage.An object of the present invention is therefore to propose a control device of the aforementioned type, said universal, the design of which makes it easy to modify the relative positioning of the input, output and fixing means of the device without impairing the performance of the device in matter degassing.

Un autre but de la présente invention est de proposer un dispositif de régulation du type précité dont la conception permet, par simple rotation, de modifier le positionnement relatif de l'enveloppe et de sa pièce de liaison sur 360° pour faire varier à volonté le positionnement des entrée et sortie de l'enveloppe en vue d'une adaptation du dispositif à tout type de véhicule.Another object of the present invention is to propose a device for regulation of the aforementioned type whose design allows, by simple rotation, to change the relative positioning of the envelope and its connecting piece 360 ° to vary at will the positioning of the input and output of the envelope in order to an adaptation of the device to any type of vehicle.

Un autre but de la présente invention est de proposer un dispositif de régulation du type précité dont la conception permet de maintenir libre l'essentiel de la surface de l'enveloppe en dépit d'un grand nombre de possibilités de positionnement de l'enveloppe et de sa pièce de liaison l'une par rapport à l'autre.Another object of the present invention is to propose a control device of the aforementioned type whose design makes it possible to keep most of the surface of the envelope free despite a large number of possibilities for positioning the envelope and of its connecting piece relative to each other.

Le positionnement d'organes de liaison de l'enveloppe à la pièce de liaison sur tout le pourtour de l'enveloppe, ces organes de liaison étant répartis de manière régulière ou non autour de ladite enveloppe, permet d'offrir un grand choix de positions de raccordement de la pièce de liaison à l'enveloppe et donc une pluralité de possibilités de positions relatives, en particulier de l'entrée de fluide de l'enveloppe par rapport à la zone de raccordement de l'enveloppe à la pièce de liaison.The positioning of connecting members of the envelope to the connecting piece around the entire periphery of the envelope, these connecting members being distributed regularly or not around said envelope, allows to offer a wide choice of positions connecting the connection piece to the envelope and therefore a plurality of possibilities of relative positions, in particular of the fluid inlet of the envelope relative to the connection area of the envelope to the connecting piece.

En outre, le positionnement des organes de liaison de l'enveloppe dans un plan parallèle au plan de joint des demi-coquilles permet de positionner les organes de liaison au voisinage, en particulier à proximité immédiate du plan de joint des demi-coquilles, laissant libre le reste de la surface de l'enveloppe pour y ménager les entrée, sortie et autre élément nécessaires au bon fonctionnement du dispositif.In addition, the positioning of the connecting members of the envelope in a plane parallel to the joint plane of the half-shells makes it possible to position the connecting members in the vicinity, in particular in the immediate vicinity of the joint plane of the half-shells, leaving free the rest of the surface of the envelope to provide the input, output and other elements necessary for the proper functioning of the device.

Le raccordement par une liaison du type à baïonnette entre la pièce de liaison et l'enveloppe permet un raccordement aisé et rapide entre lesdites pièces sans nécessiter d'outil. Le verrouillage d'un tel montage s'opère simplement par le choix des formes complémentaires des crans et des encoches, le passage d'un point dur pouvant être prévu au cours de l'insertion du cran dans l'encoche pour indiquer à l'opérateur que l'assemblage est en position verrouillée.The connection by a bayonet type connection between the connecting piece and the casing allows easy and fast connection between said parts without requiring tools. The locking of such an assembly is effected simply by the choice of the complementary shapes of the notches and the notches, the passing a hard point that can be provided during the insertion of the notch in the notch to indicate to the operator that the assembly is in the locked position.

Généralement, les organes de liaison de l'enveloppe qui, sont disposés dans un plan parallèle au plan de joint des demi-coquilles entre elles, sont répartis de manière régulière ou irrégulière sur un cercle de centre passant par l'axe de révolution de l'enveloppe, cet axe étant lui-même orthogonal au plan de joint des deux demi-coquilles. Ainsi, un positionnement et un raccordement sur 360° de la pièce de liaison à l'enveloppe sont envisageables.Generally, the connecting members of the envelope, which are arranged in a plane parallel to the joint plane of the half-shells between them, are distributed regularly or irregularly on a center circle passing through the axis of revolution of the envelope, this axis being itself orthogonal to the joint plane of the two half-shells. Thus, a positioning and a 360 ° connection of the connecting piece to the envelope are possible.

Comme mentionné ci-dessus, l'invention a pour objet un dispositif de régulation de la phase liquide d'un circuit de refroidissement d'un moteur thermique, notamment pour véhicule automobile. Ce dispositif comprend une enveloppe 1 de révolution, c'est-à-dire réalisée sous forme d'une pièce de révolution, positionnable sur le circuit de refroidissement, généralement entre la sortie de la culasse et/ou du radiateur du moteur et l'entrée du moteur. Cette enveloppe 1 de révolution est formée par deux demi-coquilles 2, 3 assemblables par un plan 9 de joint et délimitant, à l'état assemblé, une enceinte, fermée, également de révolution.As mentioned above, the subject of the invention is a device for regulating the liquid phase of a cooling circuit of a heat engine, especially for a motor vehicle. This device comprises an envelope 1 of revolution, that is to say in the form of a piece of revolution, positionable on the cooling circuit, generally between the output of the cylinder head and / or the engine radiator and the motor input. This envelope 1 of revolution is formed by two half-shells 2, 3 assembled by a plane 9 of seal and delimiting, in the assembled state, a closed enclosure, also of revolution.

Dans les exemples représentés, l'enceinte est de forme générale sphérique et chaque demi-coquille 2, 3 affecte la forme générale d'une demi-sphère. Cette enceinte aurait également pu être de forme cylindrique. L'enceinte est alimentable en fluide de refroidissement par au moins une entrée 4 de fluide comprenant un conduit d'amenée de fluide débouchant à l'intérieur de l'enceinte dans un tube plongeur équipant l'une des demi-coquilles, en l'occurrence la demi-coquille supérieure représentée en 2 aux figures. Le fluide est, une fois dégazé, évacuable de l'enceinte par l'intermédiaire d'une sortie 5 de fluide ménagée en partie basse de l'enceinte sur l'autre demi-coquille, représentée en 3 aux figures, et pouvant encore être appelée demi-coquille inférieure. Le fluide évacué de l'enceinte retourne à une pompe de circulation prévue dans le circuit de refroidissement du moteur et sert à la mise en charge du circuit de refroidissement. En d'autres termes, l'une des demi-coquilles, dite demi-coquille 2 supérieure, est munie d'une entrée 4 d'alimentation en fluide de l'enceinte et l'autre demi-coquille, dite demi-coquille 3 inférieure, est munie d'une sortie 5 de fluide de l'enceinte. Une telle enveloppe est généralement appelée boîte de dégazage.In the examples shown, the enclosure is generally spherical in shape and each half-shell 2, 3 has the general shape of a half-sphere. This pregnant could also have been cylindrical. The chamber is supplied with cooling fluid by at least one fluid inlet 4 comprising a fluid supply duct opening into the chamber into a dip tube fitted to one of the half-shells, in occurrence the upper half-shell shown in 2 in the figures. The fluid is, once degassed, evacuable from the enclosure via a fluid outlet 5 provided in the lower part of the enclosure on the other half-shell, shown at 3 in the figures, and can still be called lower half-shell. The fluid discharged from the chamber returns to a circulation pump provided in the engine cooling circuit and serves to charge the cooling circuit. In other words, one of the half-shells, said upper half-shell 2, is provided with an inlet 4 for supplying fluid to the enclosure and the other half-shell, said half-shell 3 lower, is provided with a fluid outlet 5 of the enclosure. Such an envelope is generally called a degassing box.

Le dispositif de régulation comporte encore au moins une pièce 10 de liaison pour la fixation de l'enveloppe 1 au véhicule, en particulier au châssis du véhicule. L'enveloppe 1 est équipée d'une pluralité d'organes 7 de liaison réalisés d'une seule pièce avec ladite enveloppe 1. Au moins l'un des organes 7 de liaison est apte à venir en prise avec l'organe ou un organe 11 de liaison complémentaire porté par ladite pièce 10 de liaison à l'état raccordé de la pièce 10 de liaison à l'enveloppe 1. Cette pièce 10 de liaison est généralement une pièce injectée ou moulée en matière de synthèse. Cette pièce 10 de liaison peut être réalisée en un ou plusieurs éléments. Cette pièce 10 de liaison comprend au moins un organe 11 de liaison apte à venir en prise avec un organe 7 de liaison de l'enveloppe.The regulating device also comprises at least one connecting piece 10 for fixing the casing 1 to the vehicle, in particular to the chassis of the vehicle. The casing 1 is equipped with a plurality of connecting members 7 made in one piece with said casing 1. At least one of the connecting members 7 is able to engage with the organ or an organ 11 of complementary connection carried by said connecting piece 10 in the connected state of the connecting piece 10 to the casing 1. This connecting piece 10 is generally an injected part or molded synthetic material. This connecting piece 10 can be made in one or more elements. This connecting piece 10 comprises at least one connecting member 11 adapted to engage with a body connecting member 7 of the envelope.

Dans les exemples représentés, cette pièce 10 de liaison comporte trois organes 11 de liaison disposés côte à côte.In the examples shown, this connecting piece 10 comprises three connecting members 11 arranged side by side.

De manière caractéristique à l'invention, l'enveloppe 1 comprend une pluralité d'organes 7 de liaison disposés dans un plan parallèle au plan 9 de joint des demi coquilles 2, 3 entre elles et répartis circonférentiellement sur le pourtour de ladite enveloppe 1, chaque organe 7 de liaison de l'enveloppe 1 étant apte à venir en prise avec l'organe 11 ou un organe 11 de liaison complémentaire porté par ladite pièce 10 de liaison. Lesdits organes 7 de liaison de l'enveloppe 1 sont sélectivement activables par venue en prise avec l'organe ou un organe 11 de liaison complémentaire porté par la pièce 10 de liaison en fonction du positionnement angulaire de la pièce 10 de liaison autour de l'enveloppe 1 pour un raccordement de la pièce 10 de liaison à l'enveloppe 1 en un emplacement quelconque du pourtour de l'enveloppe 1.Characteristically to the invention, the envelope 1 comprises a plurality connecting members 7 arranged in a plane parallel to the plane 9 of joint of the half shells 2, 3 between them and distributed circumferentially around the periphery of said casing 1, each member 7 connecting the casing 1 being able to come into taken with the member 11 or a complementary connecting member 11 carried by said connecting piece 10. Said connecting members 7 of the envelope 1 are selectively activatable by engagement with the member or a complementary connecting member 11 carried by the connecting piece 10 as a function of the angular positioning of the connecting piece 10 around the envelope 1 for a connection of the connecting piece 10 to the envelope 1 at any location around the perimeter of the envelope 1.

Lorsque la pièce 10 de liaison comporte un seul organe 11 de liaison complémentaire, les organes 7 de liaison de l'enveloppe 1 sont activables tour à tour de manière individuelle.When the connecting piece 10 comprises a single complementary connecting member 11, the connecting members 7 of the casing 1 are individually activatable in turn.

Lorsque la pièce 10 de liaison comporte n organes 11 de liaison complémentaires, les organes 7 de liaison de l'enveloppe 1 sont activables par groupe de n organes, n étant un nombre entier.When the connecting piece 10 has n complementary connecting members 11, the connecting members 7 of the envelope 1 can be activated by a group of n members, n being an integer.

De préférence et comme l'illustrent les figures, les organes 7 de liaison de l'enveloppe 1 sont disposés sur un cercle de centre disposé sur l'axe de révolution de l'enveloppe.Preferably and as illustrated in the figures, the connecting members 7 of the casing 1 are arranged on a center circle disposed on the axis of revolution of the casing.

Dans les exemples représentés, ces organes 7 de liaison sont répartis de manière régulière sur ledit cercle, c'est-à-dire que l'intervalle entre deux organes de liaison est constant. Cette disposition circonférentielle sur un cercle des organes 7 de liaison permet un raccordement de la pièce 10 de liaison à l'enveloppe 2 en un emplacement quelconque sur 360°.In the examples shown, these connecting members 7 are regularly distributed over said circle, that is to say that the interval between two connecting members is constant. This circumferential arrangement on a circle of the connecting members 7 allows a connection of the connecting piece 10 to the casing 2 at any location over 360 °.

De préférence, les organes 7 de liaison de l'enveloppe et le ou les organes 11 de liaison complémentaires portés par la pièce 10 de liaison sont réalisés, indifféremment, les uns sous forme de cran, les autres sous forme d'encoche pour un couplage à baïonnette de l'enveloppe 1 et la pièce 10 de liaison.Preferably, the connecting members 7 of the envelope and the one or more complementary connecting members 11 carried by the connecting piece 10 are made, indifferently, some form of notch, the others in the form of a notch for a bayonet coupling of the casing 1 and the connecting piece 10.

Dans les exemples représentés, les organes 7 de liaison de l'enveloppe 1 affectent la forme de cran et le ou les organes 11 de liaison de la pièce 10 de liaison affectent la forme d'encoche.In the examples shown, the connecting members 7 of the casing 1 affect the form of notch and the connecting member or members 11 of the connecting piece 10 affect the notch shape.

Bien évidemment, une configuration inverse, à savoir que les organes 7 de liaison de l'enveloppe 1 affectent la forme d'encoche et le ou les organes 11 de liaison complémentaires de la pièce 10 de liaison affectent la forme de cran, aurait également pu être envisagée.Of course, a reverse configuration, namely that the connecting members 7 of the envelope 1 affect the notch shape and the or the complementary connecting members 11 of the connecting piece 10 affect the notch shape, could also have been to be considered.

De préférence, les organes 7 de liaison de l'enveloppe 1 sont identiques d'un organe de liaison à un autre.Preferably, the connecting members 7 of the casing 1 are identical from one connecting member to another.

Dans les exemples représentés, les crans forment des saillies radiales externes de l'enveloppe 1 en disposition rayonnante sur le pourtour de l'enveloppe 1. Ces organes 7 de liaison sont ménagés sur la demi-coquille 3 inférieure au voisinage du plan 9 de joint. Chaque cran se présente sous forme d'un pavé de forme générale parallélépipédique, la face du dessus du pavé correspondant à la face s'étendant sensiblement parallèle au plan de joint et la plus proche du plan de joint étant munie d'une rampe inclinée facilitant l'introduction du cran dans une encoche de la pièce de liaison. Cette rampe présente deux pentes différentes, la zone de jonction entre les pentes formant un point dur à passer lors de l'introduction des crans dans une encoche pour matérialiser un positionnement adéquat des organes de liaison. Chaque encoche de la pièce 10 de liaison se présente sous forme d'une cavité jouxtée par trois bords, le quatrième bord ouvert formant une entrée à travers laquelle un cran de l'enveloppe peut pénétrer dans l'encoche. Ces encoches sont disposées l'une à la suite de l'autre sur une portion courbe concave de la pièce de liaison formant une portion de cercle de centre passant par l'axe de révolution de l'enveloppe à l'état raccordé de la pièce 10 de liaison à l'enveloppe 1, ce cercle étant de rayon sensiblement identique au rayon du cercle le long duquel les organes 7 de liaison de l'enveloppe 1 sont disposés.In the examples shown, the notches form external radial projections of the casing 1 in radiating arrangement around the periphery of the casing 1. These connecting members 7 are formed on the lower half-shell 3 in the vicinity of the joint plane 9 . Each notch is in the form of a pavé of parallelepipedal general shape, the face of the top of the block corresponding to the face extending substantially parallel to the joint plane and closest to the joint plane being provided with an inclined ramp facilitating the introduction of the notch in a notch of the connecting piece. This ramp has two different slopes, the junction zone between the slopes forming a hard point to pass during the introduction of the notches in a notch to achieve a proper positioning of the connecting members. Each notch of the connecting piece 10 is in the form of a cavity bordered by three edges, the fourth open edge forming an entrance through which a notch of the envelope can penetrate the notch. These notches are arranged one after the other on a concave curved portion of the connecting piece forming a portion of a center circle passing through the axis of revolution of the envelope in the connected state of the workpiece 10 of liaison to the casing 1, this circle being of radius substantially identical to the radius of the circle along which the connecting members 7 of the casing 1 are arranged.

Pour la venue en prise des organes 11 de liaison complémentaires de la pièce 10 de liaison avec les organes 7 de liaison de l'enveloppe 1, il suffit de positionner les organes 11 de liaison complémentaires de la pièce 10 de liaison dans l'intervalle laissé libre entre deux organes 7 de liaison de l'enveloppe 1, puis d'entraîner en rotation de manière relative l'enveloppe 1 et la pièce 10 de liaison autour de l'axe de révolution de l'enveloppe pour permettre l'introduction des organes 7 de liaison de l'enveloppe dans les organes 11 de liaison de la pièce 10 de liaison. Le passage des organes 7 de liaison de l'enveloppe 1 et du ou des organes 11 de liaison complémentaires de la pièce 10 de liaison d'une position en prise l'un ou les uns avec l'autre ou les autres à une position déverrouillée ou inversement s'opère par simple rotation relative de l'enveloppe et de la pièce 10 de liaison autour de l'axe de révolution de l'enveloppe, cet axe de révolution étant orthogonal au plan d'assemblage ou plan de joint des demi-coquilles et passant par l'orifice de sortie de l'enveloppe. Généralement, la pièce 10 de liaison se présente sous forme d'un corps allongé à l'extrémité duquel vient se raccorder l'enveloppe 1. Le porte-à-faux de l'enveloppe 1 peut générer un décrochement intempestif de l'enveloppe 1 de la pièce 10 de liaison. Pour éviter un tel problème, l'enveloppe 1 et la pièce 10 de liaison sont équipées de moyens 8, 12 anti-basculement de l'enveloppe 1 autour de sa zone de liaison à la pièce 10 de liaison, à l'état raccordé de la pièce 10 de liaison à ladite enveloppe 1. Les moyens 8 anti-basculement de l'enveloppe 1 et les moyens 12 anti-basculement de la pièce 10 de liaison affectent respectivement indifféremment les uns, la forme d'organes mâles, tels que des languettes, les autres, la forme d'organes femelles, tels qu'une goulotte à l'intérieur desquels les organes mâles sont aptes à s'insérer à l'état raccordé de la pièce 10 de liaison à l'enveloppe 1. Généralement, les moyens 8 anti-basculement de l'enveloppe 1 et les organes 7 de liaison du départ 6 de fixation en attente de l'enveloppe 1 sont décalés axialement le long de l'axe de révolution de l'enveloppe 1 et sont disposés respectivement sur un cercle de centre positionné sur l'axe de révolution de l'enveloppe 1, ledit axe de révolution étant orthogonal au plan 9 de joint des demi-coquilles 2, 3 de l'enveloppe 1.For the engagement of the complementary connecting members 11 of the connecting piece 10 with the connecting members 7 of the casing 1, it is sufficient to position the complementary connecting members 11 of the connecting piece 10 in the gap left free between two connecting members 7 of the casing 1, then rotate in relative manner the casing 1 and the connecting piece 10 around the axis of revolution of the casing to allow the introduction of organs 7 connecting the envelope in the connecting members 11 of the connecting piece 10. The passage of the connecting members 7 of the casing 1 and the one or more complementary connecting members 10 of the connecting piece 10 from a position in engagement with one or the other or the others to an unlocked position or conversely operates by simple relative rotation of the envelope and the connecting piece 10 around the axis of revolution of the envelope, this axis of revolution being orthogonal to the assembly plane or joint plane of the half shells and passing through the exit port of the envelope. Generally, the connecting piece 10 is in the form of an elongate body at the end of which is connected the casing 1. The overhang of the casing 1 can generate an inadvertent detachment of the casing 1 of the connecting piece 10. To avoid such a problem, the casing 1 and the connecting piece 10 are provided with means 8, 12 anti-tilting of the casing 1 around its connection zone to the connecting piece 10, in the connected state of the connecting piece 10 to said casing 1. The anti-tilting means 8 of the casing 1 and the anti-tilting means 12 of the connecting piece 10 respectively affect one or the other, the form of male members, such as tongues, the others, the form of female members, such as a chute in which the male members are adapted to be inserted in the connected state of the connecting piece 10 to the envelope 1. Generally, the anti-tilting means 8 of the casing 1 and the connecting members 7 of the fixing start 6 waiting for the casing 1 are offset axially along the axis of revolution of the casing 1 and are arranged respectively on a center circle positioned on the axis of revolution of the casing 1, said axis of revolution being orthogonal to the joint plane 9 of the half-shells 2, 3 of the casing 1.

Dans les exemples représentés, les moyens 8 anti-basculement de l'enveloppe sont de préférence portés par la même demi-coquille que celle qui porte les organes de liaison, à savoir la demi-coquille inférieure. Ces moyens 8 anti-basculement sont à nouveau disposés sur un cercle de centre positionné sur l'axe de révolution de l'enveloppe et dans un plan parallèle au plan de joint de l'enveloppe, lui-même orthogonal à l'axe de révolution de l'enveloppe. Ces moyens 8 anti-basculement de l'enveloppe se présentent sous forme de languettes prenant naissance sur le corps de l'enveloppe et se développant suivant une direction sensiblement parallèle à l'axe de révolution de l'enveloppe en direction du sommet de la demi-coquille qui porte les languettes pour former une crénelure. Ces moyens 8 anti-basculement de l'enveloppe forment donc sur la demi-coquille qui les porte un deuxième cercle qui vient doubler le premier cercle formé par les organes de liaison. Les moyens 12 anti-basculement de la pièce 10 de liaison sont quant à eux réalisés sous forme d'une rampe circulaire disposée sur un cercle de centre positionné sur l'axe de révolution de l'enveloppe à l'état relié de la pièce 10 de liaison à l'enveloppe.In the examples shown, the anti-tilt means 8 of the envelope are preferably carried by the same half-shell as that which carries the connecting members, namely the lower half-shell. These anti-tilt means 8 are again arranged on a center circle positioned on the axis of revolution of the envelope and in a plane parallel to the joint plane of the envelope, itself orthogonal to the axis of revolution. of the envelope. These means 8 anti-tilting of the envelope are in the form of tabs originating on the body of the envelope and developing in a direction substantially parallel to the axis of revolution of the envelope towards the top of the half -coquille that wears the tabs to form a crenelure. These anti-tilt means 8 of the envelope thus form on the half-shell which carries them a second circle which comes to double the first circle formed by the connecting members. The means 12 anti-tilting of the connecting piece 10 are in turn formed as a circular ramp disposed on a center circle positioned on the axis of revolution of the envelope in the connected state of the part 10 link to the envelope.

Pour la venue en prise des moyens 8 anti-basculement de l'enveloppe 1 avec les moyens 12 anti-basculement de la pièce 10 de liaison, on procède comme suit. Les moyens 8 anti-basculement de l'enveloppe 1 sont dans un premier temps positionnés dans la rampe ou goulotte formant les moyens 12 anti-basculement de la pièce 10 de liaison puis la pièce 10 de liaison est basculée autour de cette zone de liaison de sorte que les organes 11 de liaison complémentaires de la pièce 10 de liaison viennent se positionner dans l'intervalle laissé libre entre deux organes 7 de liaison de l'enveloppe 2. Une rotation relative entre pièce 10 de liaison et enveloppe 1 autour de l'axe de révolution de l'enveloppe est opérée de sorte que les moyens 8 anti-basculement de l'enveloppe glissent dans les moyens 12 anti-basculement de la pièce 10 de liaison tandis que les organes 7 de liaison de l'enveloppe 2 pénètrent dans les organes 11 de liaison de la pièce 10 de liaison. Le raccordement est alors terminé. Pour séparer la pièce 10 de liaison de l'enveloppe 1, il suffit d'opérer de manière inverse.For the engagement of the anti-tilt means 8 of the casing 1 with the anti-tilting means 12 of the connecting piece 10, the procedure is as follows. The anti-tilt means 8 of the casing 1 are firstly positioned in the ramp or chute forming the means 12 anti-tilting of the connecting part 10 and then the connecting part 10 is tilted around this connection zone of so that the complementary connecting members 11 of the connecting piece 10 are positioned in the gap left free between two connecting members 7 of the casing 2. A relative rotation between the connecting piece 10 and casing 1 around the axis of revolution of the envelope is operated so that the means 8 anti-tilting of the envelope slip in the means 12 anti-tilting of the connecting piece 10 while the connecting members 7 of the casing 2 penetrate into the connecting members 11 of the connecting piece 10. The connection is then completed. To separate the connecting piece 10 from the envelope 1, it suffices to operate in the opposite way.

Il doit être noté que l'efficacité de la boîte de dégazage du dispositif est due essentiellement au fait que l'orifice de sortie, ménagé en partie basse de l'enceinte, est entouré par une paroi continue délimitant, à l'intérieur de l'enceinte, une chambre autour de laquelle le fluide peut circuler à l'intérieur d'une fosse entourant ladite chambre. Cette chambre, ouverte à son sommet, isole l'orifice de sortie du débouché du tube plongeur dont l'extrémité libre est disposée, dans ladite enceinte, à l'extérieur de la chambre, dans la fosse, au dessous du niveau du bord supérieur ou libre de la paroi de séparation chambre/fosse, pouvant encore être appelée paroi de délimitation de la chambre. L'extrémité libre du tube plongeur est ainsi maintenue de manière permanente immergée dans le fluide présent dans la fosse, ce fluide circulant dans ladite fosse avant de pénétrer dans la chambre par passage au-dessus de la paroi de délimitation de la chambre.It should be noted that the effectiveness of the degassing box of the device is mainly due to the fact that the outlet orifice, formed in the lower part of the enclosure, is surrounded by a continuous wall delimiting, inside the enclosure, a chamber around which the fluid can circulate inside a pit surrounding said chamber. This chamber, open at its top, isolates the outlet orifice from the outlet of the dip tube whose free end is disposed in said chamber outside the chamber, in the pit, below the level of the upper edge. or free of the chamber / pit partition wall, which can still be called the chamber delimiting wall. The free end of the plunger tube is thus permanently immersed in the fluid present in the pit, the fluid flowing in said pit before entering the chamber by passing above the delimiting wall of the chamber.

La paroi de délimitation de la chambre à fonction également de paroi de séparation de la chambre de la fosse allonge nécessairement le parcours du liquide à l'intérieur de l'enceinte entre le conduit d'amenée et l'orifice de sortie améliorant ainsi la qualité de dégazage.The boundary wall of the chamber also functions as a separation wall of the chamber of the pit necessarily lengthens the path of the liquid inside the chamber between the supply duct and the outlet orifice thus improving the quality. degassing.

Cette paroi de séparation chambre/fosse est une paroi circulaire centrée sur l'axe de révolution de l'enveloppe, orthogonal au plan de joint des deux demi-coquilles et passant par l'orifice de sortie de fluide. La paroi de séparation chambre/fosse et la paroi de délimitation de l'enceinte qui forment les rives de la fosse et le tube plongeur sont configurés, c'est-à-dire en particulier dimensionnés et conformés, de sorte que le tube plongeur est apte à parcourir entièrement la fosse, c'est-à-dire apte à parcourir la fosse en effectuant un tour complet autour de la chambre, à l'état en contact d'appui par leur plan de joint des demi-coquilles lors d'un déplacement en rotation sur 360° de la demi-coquille munie du tube plongeur autour de l'axe de révolution de l'enveloppe orthogonal au plan de joint des deux demi-coquilles.This chamber / pit separation wall is a circular wall centered on the axis of revolution of the envelope, orthogonal to the joint plane of the two half-shells and passing through the fluid outlet orifice. The chamber / pit partition wall and the boundary wall of the enclosure which form the banks of the pit and the dip tube are configured, that is to say in particular dimensioned and shaped, so that the dip tube is able to go completely through the pit, that is to say able to go through the pit by performing a complete turn around the chamber, in the state in contact by support by their joint plane half-shells during a rotational movement 360 ° of the half-shell provided with the dip tube around the axis of revolution of the orthogonal envelope to the joint plane of the two half-shells.

En d'autres termes, le tube plongeur peut tourner sur 360° autour de la chambre avec son extrémité libre disposée dans la fosse et faire le tour complet de ladite chambre à l'état en contact d'appui des demi-coquilles par leur plan de joint et, lors d'un entraînement relatif à rotation des demi-coquilles, autour de l'axe de révolution orthogonal au plan de joint ou au plan moyen d'assemblage des demi-coquilles sans qu'aucun obstacle ne vienne s'opposer à ce déplacement. L'extrémité libre du tube plongeur peut donc suivre une trajectoire circulaire sur 360° à l'intérieur de la fosse sans rencontrer d'obstacle. Ainsi, les demi-coquilles peuvent également être assemblées l'une à l'autre suivant un positionnement angulaire quelconque.In other words, the dip tube can rotate 360 ° around the chamber with its free end disposed in the pit and make a complete turn of said chamber in the state in contact with the support of the half-shells by their plane of joint and, during a relative drive rotation of the half-shells, around the axis of revolution orthogonal to the joint plane or the mean assembly plane of the half-shells without any obstacle comes to oppose to this displacement. The free end of the dip tube can follow a 360 ° circular path inside the pit without encountering obstacles. Thus, the half-shells can also be assembled to each other in any angular position.
