[0001] La présente invention revendique la priorité de la demande française 0958604 déposée le 3 décembre 2009 dont le contenu (texte, dessins et revendications) est ici incorporé par référence. The present invention claims the priority of the French application 0958604 filed December 3, 2009 whose content (text, drawings and claims) is here incorporated by reference.
[ooo2] La présente invention concerne une boîte de dégazage de circuit de liquide de véhicule, en particulier une boîte de dégazage de circuit de liquide de refroidissement de moteur de véhicule automobile. The present invention relates to a vehicle fluid circuit degassing box, in particular a motor vehicle coolant circuit degassing box.
[ooo3] Dans les véhicules automobiles, la boîte de dégazage du circuit de refroidissement est un élément important. Elle assure la séparation des gaz, en particulier de l'air, qui se trouvent en solution dans le liquide et dont la présence dans le circuit de refroidissement est néfaste pour son bon fonctionnement. Par sa fonction de réservoir, elle permet de compenser les pertes dans le circuit et d'absorber les dilatations du liquide de refroidissement. Elle sert aussi au remplissage du circuit et au contrôle du niveau du liquide de refroidissement. [ooo3] In motor vehicles, the cooling system's degassing box is an important element. It ensures the separation of gases, in particular air, which are in solution in the liquid and whose presence in the cooling circuit is detrimental to its proper functioning. By its reservoir function, it makes it possible to compensate the losses in the circuit and to absorb the expansions of the coolant. It is also used to fill the circuit and control the level of the coolant.
[ooo4] On connaît déjà des pièces formant réservoirs de liquide, qui présentent des moyens adaptés pour faciliter leur remplissage. [Ooo4] There are already known parts forming liquid tanks, which have suitable means to facilitate their filling.
[ooo5] Ainsi, à titre d'exemple, le document FR 2 41 1 306 décrit un bouchon fileté pour une tubulure de remplissage de radiateur ou vase d'équilibrage incorporé à un circuit de refroidissement d'un moteur à combustion interne d'un véhicule automobile. Le bouchon fileté est muni de moyens pour évacuer l'eau de refroidissement en phase vapeur ou liquide, et est, de préférence, réalisé en matière plastique. Il comprend un tube de trop-plein et d'évacuation de la vapeur, qui peut être relié à un couvercle, et au moins un canal entre l'espace intérieur de la tubulure de remplissage et le tube d'évacuation de la vapeur. [ooo5] Thus, for example, the document FR 2 41 1 306 discloses a threaded plug for a radiator filling pipe or balancing vessel incorporated in a cooling circuit of an internal combustion engine of a motor vehicle. The threaded plug is provided with means for evacuating the cooling water in the vapor or liquid phase, and is preferably made of plastic. It includes an overflow and steam discharge tube, which can be connected to a lid, and at least one channel between the interior space of the filler neck and the steam discharge tube.
[ooo6] Le but de la présente invention est de fournir une nouvelle boîte de dégazage de circuit de liquide, qui puisse être implantée dans des zones peu accessibles du bloc avant du véhicule, et puisse être déplacée dans une position facilitant son remplissage. [0007] Un autre but de la présente invention est de fournir une telle boîte de dégazage, qui, ainsi placée dans une zone peu accessible, soit en conformité avec les normes existantes et futures en matière de sécurité passive des véhicules automobiles, en particulier les normes « EuroNCAP » (acronyme de l'organisme dit « Européan New Car Assessment Program » qui a pour fonction d'effectuer des « crash tests » afin de tester la sécurité passive des véhicules automobiles). The object of the present invention is to provide a new liquid circuit degassing box, which can be implanted in inaccessible areas of the front block of the vehicle, and can be moved to a position facilitating its filling. Another object of the present invention is to provide such a degassing box, which, thus placed in an inaccessible area, is in accordance with existing and future standards for passive safety of motor vehicles, particularly the "EuroNCAP" standards (acronym for the "European New Car Assessment Program" organization, whose function is to perform "crash tests" to test the passive safety of motor vehicles).
[ooo8] Enfin, c'est également un but de la présente invention de fournir une telle boîte de dégazage, qui soit de conception et de réalisation simples, qui soit robuste et économique. [ooo8] Finally, it is also an object of the present invention to provide such a degassing box, which is simple in design and construction, which is robust and economical.
[ooo9] Pour parvenir à ces buts, la présente invention a pour objet une boîte de dégazage de circuit de liquide de véhicule, en particulier une boîte de dégazage pour circuit de liquide de refroidissement de moteur à combustion interne de véhicule automobile, et cette nouvelle boîte comprend essentiellement une enveloppe extérieure composée de deux demi-coques assemblées selon un premier plan de joint. La demi-coque supérieure comporte elle-même deux parties assemblées selon un second plan de joint, à savoir une partie inférieure et une partie supérieure, cette dernière pouvant tourner sur elle-même et portant une tubulure de remplissage de la boîte dirigée selon un axe incliné par rapport à son axe de rotation sur elle-même, de telle sorte que la rotation de ladite partie supérieure de la demi-coque supérieure permet le déplacement de la tubulure de remplissage entre une position initiale et une position de remplissage plus accessible que la position initiale pour effectuer le remplissage en liquide de la boîte de dégazage. [ooi o] Selon le mode de réalisation préféré de la présente invention, le second plan de joint est sensiblement parallèle au premier plan de joint. To achieve these objects, the present invention relates to a vehicle fluid circuit degassing box, in particular a degassing box for a motor vehicle internal combustion engine coolant circuit, and this new invention box essentially comprises an outer shell composed of two half-shells assembled according to a first joint plane. The upper half-shell itself comprises two parts assembled in a second joint plane, namely a lower part and an upper part, the latter being able to turn on itself and carrying a filling pipe of the box directed along an axis. inclined relative to its axis of rotation on itself, so that the rotation of said upper portion of the upper half-shell allows the displacement of the filler neck between an initial position and a more accessible filling position that the initial position to perform the liquid filling of the degassing box. [Ooi o] According to the preferred embodiment of the present invention, the second joint plane is substantially parallel to the first joint plane.
[ooi i] Selon le mode de réalisation préféré de la présente invention également, l'enveloppe extérieure est de forme sensiblement sphérique, les deux demi- coques étant alors sensiblement de forme semi sphérique. [0012] De manière préférentielle, le premier plan de joint et le second plan de joint sont sensiblement horizontaux ou légèrement inclinés sur l'horizontale. According to the preferred embodiment of the present invention also, the outer casing is of substantially spherical shape, the two half-shells then being substantially semispherical in shape. Preferably, the first joint plane and the second joint plane are substantially horizontal or slightly inclined to the horizontal.
[0013] De manière avantageuse, un joint d'étanchéité, cylindrique, est prévu dans le second plan de joint, de façon à garder l'étanchéité entre la partie supérieure et la partie inférieure de la demi-coque supérieure. Advantageously, a seal, cylindrical, is provided in the second joint plane, so as to maintain the seal between the upper part and the lower part of the upper half-shell.
[0014] Selon la présente invention, la partie supérieure de la demi-coque supérieure est assemblée par « clippage » sur la partie inférieure de ladite demi- coque supérieure. According to the present invention, the upper part of the upper half-shell is assembled by "clipping" on the lower part of said upper half-shell.
[0015] La présente invention a également pour objet un véhicule, en particulier un véhicule automobile, qui comprend un moteur à combustion interne, un circuit de liquide de refroidissement dudit moteur et une boîte de dégazage dudit circuit. Dans ce véhicule, la boîte de dégazage est conforme à celle décrite ci-dessus dans ses grandes lignes et elle est située en position initiale, inaccessible ou peu accessible, sous un auvent du bloc avant du véhicule. Elle peut être amenée en position de remplissage, accessible, après rotation sur elle-même de la partie supérieure de la demi-coque supérieure. The present invention also relates to a vehicle, in particular a motor vehicle, which comprises an internal combustion engine, a coolant circuit of said engine and a degassing box of said circuit. In this vehicle, the degassing box is in line with that described above in outline and is located in the initial position, inaccessible or inaccessible, under an awning of the front block of the vehicle. It can be brought into filling position, accessible, after rotation on itself of the upper part of the upper half-shell.
[ooi 6] D'autres buts, avantages et caractéristiques de l'invention apparaîtront dans la description qui suit d'un mode de réalisation préféré, non limitatif de l'objet et de la portée de la présente demande de brevet, accompagnée de dessins dans lesquels : Other objects, advantages and features of the invention will become apparent from the following description of a preferred, non-limiting embodiment of the object and scope of the present patent application, together with drawings. wherein :

FIG. 3 is a perspective view of the degassing box of FIG. 1, showing the two positions of the filling tube, and • Figure 4 shows, schematically, the degassing box of Figures 1 to 3 implanted under awning in a poorly accessible area of the front block of a motor vehicle.
[ooi 7] En référence au dessin de la figure 1 , on a représenté une boîte de dégazage de circuit de liquide de refroidissement de moteur à combustion interne d'un véhicule automobile, qui comprend essentiellement une enveloppe extérieure, des pattes de fixation désignées par la référence collective 16 et des entrée/sortie de fluide désignées sous lé référence collective 17 (figure 3). [Ooi 7] With reference to the drawing of Figure 1, there is shown an internal combustion engine engine coolant circuit degassing box of a motor vehicle, which essentially comprises an outer casing, fastening lugs designated by collective reference 16 and fluid inlet / outlet designated as collective reference 17 (FIG. 3).
[ooi 8] L'enveloppe constitutive de la boîte de dégazage est de forme sensiblement sphérique, et est composée de deux demi-coques 1 1 et 12 sensiblement de forme semi sphérique. Les deux demi-coques 1 1 et 12 sont assemblées selon un premier plan de joint référencé P1 . [Ooi 8] The casing constituting the degassing box is substantially spherical in shape, and is composed of two half-shells 1 1 and 12 substantially semi-spherical shape. The two half-shells 1 1 and 12 are assembled in a first joint plane referenced P1.
[0019] La demi-coque supérieure 12 est elle-même constituée en deux parties assemblées selon un second plan de joint référencé P2, à savoir une partie inférieure 12A et une partie supérieure 12B. La partie supérieure 12B peut tourner sur elle-même et porte une tubulure de remplissage 14 fermée par un bouchon 15 et dirigée selon un axe T, qui est incliné par rapport à l'axe Y de rotation sur elle-même de la partie supérieure 12B. De cette manière, la rotation (illustrée par la flèche « R ») de la partie supérieure 12B de la demi-coque supérieure 12 provoque le déplacement de la tubulure de remplissage 14 entre une position initiale et une position de remplissage plus accessible que la position initiale pour effectuer le remplissage en liquide de la boîte de dégazage. The upper half-shell 12 itself consists of two parts assembled according to a second joint plane referenced P2, namely a lower portion 12A and an upper portion 12B. The upper part 12B can rotate on itself and carries a filler neck 14 closed by a plug 15 and directed along an axis T, which is inclined relative to the axis Y of rotation on itself of the upper part 12B . In this way, the rotation (illustrated by the arrow "R") of the upper part 12B of the upper half-shell 12 causes the filling pipe 14 to move between an initial position and a more accessible filling position than the position initially to fill the degassing box with liquid.
[0020] Ces deux positions sont mieux représentées sur le dessin de la figure 3, la position initiale étant en traits pleins tandis que la position de remplissage est en traits interrompus mixtes. Après rotation sur elle-même « R » autour de l'axe Y de la partie supérieure 12B de la demi-coque supérieure 12, le tube de remplissage 14 d'axe T et fermé par le bouchon 15 est déplacé et sa position nouvelle est illustrée en traits interrompus mixtes par le tube de référence 14', d'orientation nouvelle selon l'axe T', fermé par le bouchon 15'. [0021 ] En référence aux dessins des figures 1 et 3, le second plan de joint P2, c'est-à-dire le plan de liaison des deux parties 12A et 12B formant la demi-coque supérieure 12, est sensiblement parallèle au premier plan de joint P1 , c'est-à-dire le plan de liaison de la partie inférieure 12A de la demi-coque supérieure 12 avec la demi-coque inférieure 1 1 . These two positions are best shown in the drawing of Figure 3, the initial position being in solid lines while the filling position is in broken dotted lines. After rotating on itself "R" about the Y axis of the upper portion 12B of the upper half-shell 12, the filling tube 14 of axis T and closed by the plug 15 is moved and its new position is shown in broken lines mixed by the reference tube 14 ', of new orientation along the axis T', closed by the plug 15 '. With reference to the drawings of Figures 1 and 3, the second joint plane P2, that is to say the connecting plane of the two parts 12A and 12B forming the upper half-shell 12, is substantially parallel to the first joint plane P1, that is to say the connection plane of the lower portion 12A of the upper half-shell 12 with the lower half-shell 1 1.
[0022] De manière avantageuse, le premier plan de joint P1 et le second plan de joint P2 sont sensiblement horizontaux ou légèrement inclinés sur l'horizontale. Advantageously, the first joint plane P1 and the second joint plane P2 are substantially horizontal or slightly inclined to the horizontal.
[0023] Comme mieux représenté sur le dessin de la figure 2, il est prévu un joint d'étanchéité, de référence 20, cylindrique, dans le second plan de joint P2, qui a pour fonction de garder l'étanchéité entre la partie supérieure 12B et la partie inférieure 12A de la demi-coque supérieure 12. As best shown in the drawing of Figure 2, there is provided a seal, reference 20, cylindrical in the second joint plane P2, which has the function of keeping the seal between the upper part 12B and the lower portion 12A of the upper half-shell 12.
[0024] La partie supérieure 12B de la demi-coque supérieure 12 est assemblée par « clippage » sur la partie inférieure 12A de ladite coque supérieure 12. The upper portion 12B of the upper half-shell 12 is assembled by "clipping" on the lower portion 12A of said upper shell 12.
[0025] Comme représenté sur la figure 4, la boîte de dégazage de l'invention, de référence générale 10, est située en position initiale, inaccessible ou peu accessible, sous un auvent 30 du bloc avant du véhicule, et peut être amenée en position de remplissage, accessible, après rotation « R » sur elle-même de la partie supérieure 12B de sa demi-coque supérieure 12, comme décrit précédemment. [0026] La boîte de dégazage décrite ci-dessus présente de nombreux avantages, parmi lesquels les avantages suivants : As shown in Figure 4, the degassing box of the invention, general reference 10, is located in the initial position, inaccessible or inaccessible, under an awning 30 of the front block of the vehicle, and can be brought into filling position, accessible, after rotation "R" on itself of the upper portion 12B of its upper half-shell 12, as described above. The degassing box described above has many advantages, among which the following advantages:
• elle peut être implantée dans une zone peu accessible du bloc avant du véhicule, sous un auvent de structure, • it can be located in an inaccessible area of the front block of the vehicle, under a structure canopy,
• elle est en conformité avec les normes existantes et futures en matière de sécurité passive des véhicules automobiles, en particulier les futures normes « EuroNCAP » 2013, parce qu'une fois remplie on peut placer son tube de remplissage dans une zone inaccessible en choc tête. • it is in compliance with the existing and future standards for passive safety of motor vehicles, in particular the future "EuroNCAP" 2013 standards, because once filled one can place his filling tube in an inaccessible zone in head shock .
• elle est conception et de réalisation simples, et • enfin, elle est économique. • It is simple design and realization, and • finally, it is economical.
[0027] Bien entendu, la présente invention n'est pas limitée au mode de réalisation décrit et représenté ci-dessus à titre d'exemple ; d'autres modes de réalisation peuvent être conçus par l'homme de métier sans sortir du cadre et de la portée de la présente invention. Of course, the present invention is not limited to the embodiment described and shown above by way of example; other embodiments may be devised by those skilled in the art without departing from the scope and scope of the present invention.
