Description

Coque de protection pour raccords de tuyaux de liquides Protective shell for liquid pipe fittings
L'invention concerne le domaine des dispositifs de protection adaptés à des raccords de tuyaux de liquides.The invention relates to the field of protective devices adapted to liquid pipe connections.
L'invention concerne plus particulièrement une coque de protection adaptée à un raccord de tuyau de liquides, tels que par exemple des raccords de tuyaux d'alimentation en carburant. Dans un compartiment moteur, une pompe d'injection assure une distribution sous pression du carburant à une rampe d'alimentation. Des fuites peuvent survenir lorsque un raccord entre deux tuyaux d'alimentation, ou entre un tuyau d'alimentation en carburant et une rampe d'injection est défaillant ou a été mal installé. Dans ce cas, il existe un risque de fuites du carburant dans le compartiment moteur dues à l'aspersion de liquide gênant le fonctionnement du véhicule par exemple.The invention more particularly relates to a protective shell adapted to a liquid pipe connection, such as, for example, fuel supply pipe connections. In an engine compartment, an injection pump provides a pressurized delivery of fuel to a fuel rail. Leaks can occur when a connection between two supply hoses, or between a fuel supply line and an injection manifold is faulty or has been incorrectly installed. In this case, there is a risk of fuel leakage in the engine compartment due to the spraying of liquid impeding the operation of the vehicle for example.
Une solution à ce problème est décrite dans le document WO2006059050 où un dispositif de protection permet de contenir les fuites de carburant dues par exemple à une mauvaise étanchéité du raccord. Ce dispositif de protection comporte deux éléments de protection délimitant une enceinte fermée et étanche pour confiner les fuites de carburant du raccord, et présentant un orifice d'évacuation ménagé au niveau d'un desdits éléments de protection apte à permettre un écoulement du carburant vers l'extérieur. Un embout d'évacuation s'étendant également à partir de cet orifice permet d'évacuer les fuites en conduisant le carburant vers un réservoir de stockage par exemple. Dans cet agencement du document WO2006059050, l'étanchéité du dispositif de protection est assurée par des joints d'étanchéité montés serrés en sandwich lors de l'assemblage. Ce dispositif de protection permet donc de pouvoir contenir d'éventuelles fuites de carburant et de les canaliser en direction d'une zone non dangereuse par exemple. Un tel dispositif de protection est idéal pour des fuites de carburant et permet de récupérer de telles fuites. Toutefois, son utilisation peut paraître trop sophistiquée si l'on veut juste éviter que les fuites ne se déversent à des endroits précis, sans avoir à récupérer les fuites de liquide, notamment lorsque l'environnement du raccord est déjà encombré. Un but de l'invention est de proposer une coque de protection améliorée et simple d'utilisation.A solution to this problem is described in WO2006059050 where a protection device makes it possible to contain the fuel leaks due for example to a poor seal of the fitting. This protection device comprises two protection elements delimiting a sealed and sealed enclosure for confining the fuel leaks of the coupling, and having a discharge orifice formed at one of said protective elements capable of allowing a flow of fuel towards the fuel tank. 'outside. An exhaust tip also extending from this port allows to evacuate the leaks by driving the fuel to a storage tank for example. In this arrangement of WO2006059050, the sealing of the protective device is provided by seals tightly sandwiched during assembly. This protection device therefore allows to contain possible fuel leaks and channel them towards a non-hazardous area for example. Such a protection device is ideal for fuel leaks and allows to recover such leaks. However, its use may seem too sophisticated if we just want to prevent leaks from spilling to specific locations, without having to recover liquid leaks, especially when the environment of the connection is already congested. An object of the invention is to provide an improved protective shell and easy to use.
Dans ce but, l'invention a pour objet une coque de protection adaptée à un raccord de tuyau de liquide d'un véhicule, la coque comprenant deux éléments de protection en vis-à-vis délimitant une enceinte pour le confinement de fuites du liquide provenant du raccord, et un moyen d'évacuation desdites fuites apte à permettre un écoulement vers l'extérieur des fuites de liquide récupérées dans ladite coque, caractérisé en ce qu'une extrémité de la coque délimite une ouverture prévue pour entourer ledit tuyau, ladite ouverture ayant une largeur supérieure à la largeur extérieure dudit tuyau, la coque comportant des moyens de serrage apte à serrer le tuyau et le maintenir sensiblement au centre de ladite ouverture tout en maintenant le tuyau à distance de l'ouverture, l'ouverture étant apte à diriger vers l'extérieur les fuites de liquide.For this purpose, the subject of the invention is a protective shell adapted to a fluid pipe fitting of a vehicle, the shell comprising two protective elements facing each other delimiting an enclosure for confining liquid leaks. from the coupling, and a means of evacuation of said leaks capable of allowing outward flow of liquid leaks recovered in said shell, characterized in that one end of the shell defines an opening provided to surround said pipe, said opening having a width greater than the outer width of said pipe, the shell having clamping means adapted to clamp the pipe and maintain substantially in the center of said opening while maintaining the pipe away from the opening, the opening being fit to direct outward liquid leaks.
Une telle coque permet non pas de récupérer les fuites de liquides mais de les diriger vers une zone connue ne comportant pas de risques. En effet, des fuites de carburant peuvent par exemple asperger le compartiment moteur suite à une mauvaise étanchéité d'un ou plusieurs joints d'étanchéité. La coque présente une extrémité ouverte vers l'extérieur permettant seulement de diriger les fuites vers une direction connue sans les récupérer, notamment lorsque la récupération du liquide s'avère laborieuse et n'est pas toujours possible dans un environnement encombré.Such a shell makes it possible not to recover liquid leaks but to direct them to a known area that does not involve risks. Indeed, fuel leaks may for example spray the engine compartment following a poor seal of one or more seals. The shell has an open end to the outside only to direct leaks to a known direction without recovering, especially when the recovery of the liquid is laborious and is not always possible in a crowded environment.
L'utilisation d'une telle coque permet avantageusement qu'une fuite de liquides, tel que par exemple du carburant ou d'un liquide de refroidissement, n'asperge pas un turbocompresseur, ou un collecteur d'échappement, permettant ainsi d'éviter un choc thermique. Nombre de raccords sont normalisés et une telle coque peut également être normalisée et s'adapter ainsi à ceux-ci. Selon d'autres caractéristiques,The use of such a shell advantageously allows leakage of liquids, such as for example fuel or a coolant, does not spray a turbocharger, or an exhaust manifold, thus avoiding a thermal shock. Many fittings are standardized and such a shell can also be standardized and thus fit them. According to other characteristics,
- l'ouverture peut être circulaire et peut être prévue pour entourer un tuyau circulaire d'une façon concentrique, - les moyens de serrage peuvent comporter au moins deux membranes arquées, dirigées vers le centre de l'ouverture,the opening may be circular and may be provided to surround a circular pipe in a concentric manner, the clamping means may comprise at least two arcuate membranes, directed towards the center of the opening,
- les moyens de serrage peuvent être intégrés à la coque, par exemple par moulage, de façon à optimiser le temps de fabrication des coques de protection, - les moyens de serrage comportent deux membranes, appartenant chacune à un élément de protection, les deux membranes peuvent être arquées vers le centre de l'ouverture et fixées chacune sur deux points de l'élément de protection associé, - les éléments de protection peuvent être des demi coques, une demi coque étant sensiblement l'image réfléchie l'autre demi coque symétriquement,the clamping means can be integrated into the shell, for example by molding, so as to optimize the manufacturing time of the protective shells, the clamping means comprise two membranes, each belonging to a protection element, the two membranes can be arched towards the center of the opening and each fixed on two points of the associated protection element; the protection elements can be half-shells, a half shell being substantially the image reflected the other half-shell symmetrically,
- la coque peut être coudée.- the hull can be bent.
L'invention concerne également un usage d'une telle coque, le liquide pouvant être un carburant, un liquide de refroidissement, un lave glace ou une huile. L'invention sera mieux comprise par la description ci-après d'un mode de réalisation donné à titre d'exemple non limitatif en référence aux dessins annexés, sur lesquels :The invention also relates to a use of such a shell, the liquid being a fuel, a cooling liquid, an ice wash or an oil. The invention will be better understood from the following description of an embodiment given by way of non-limiting example with reference to the accompanying drawings, in which:
- la figure 1 représente une vue de profil d'un raccord disposé entre un tuyau et une rampe d'injection, recouvert d'un élément de protection d'une coque selon l'invention,FIG. 1 represents a profile view of a coupling disposed between a pipe and an injection rail, covered with a protective element of a shell according to the invention,

- la figure 3 représente une vue en perspective de l'intérieur de la coque selon un premier mode de réalisation,FIG. 3 represents a perspective view of the inside of the shell according to a first embodiment,
- la figure 4 représente une vue en perspective de la coque en position ouverte selon un deuxième mode de réalisation.- Figure 4 shows a perspective view of the hull in the open position according to a second embodiment.
Une rampe d'injection 1 , partiellement représentée sur la figure 1 , est reliée à une extrémité d'un tuyau 2 par l'intermédiaire d'un raccord 3.An injection manifold 1, partially shown in FIG. 1, is connected to one end of a pipe 2 via a coupling 3.
Le raccord 3 est emmanché à l'intérieur du tuyau 2. L'autre extrémité du tuyau 2 est reliée à un module d'aspiration non représenté situé à l'arrière d'un véhicule. Un dispositif de protection sous la forme d'une coque 4 est utilisé pour le confinement de fuites de carburant pour permettre vers l'extérieur une évacuation orientée vers des zones non dangereuses ou qui ne présentent aucun risque particulier en cas de fuite. Sur la figure 1 , seul un élément de protection 42 de la coque 4, montée autour du raccord 3, a été représenté pour expliciter l'agencement intérieur du raccord 3, du tuyau 2 et de la rampe d'injection 1.The connector 3 is fitted inside the pipe 2. The other end of the pipe 2 is connected to a not shown suction module located at the rear of a vehicle. A protective device in the form of a shell 4 is used for the containment of fuel leaks to allow outward evacuation directed towards non-hazardous areas or that pose no particular risk in case of leakage. In FIG. 1, only a protective element 42 of the shell 4, mounted around the coupling 3, has been shown to explain the internal arrangement of the coupling 3, the pipe 2 and the injection rail 1.
La coque 4 telle que représentée sur les figures 2,3,4 comporte deux éléments 41 ,42 de protection en vis-à-vis délimitant une enceinte pour le confinement de fuites du raccord 3 obtenus par exemple par moulage à partir d'un procédé d'injection plastique. Lorsque la coque 4 est utilisée pour une protection de fuites de carburant, le matériau utilisé pour le moulage est de préférence le polyamide, capable de résister à de fortes températures.The shell 4 as shown in FIGS. 2, 3, 4 comprises two elements 41, 42 for protecting vis-à-vis delimiting an enclosure for the containment of leaks of the coupling 3 obtained for example by molding from a process plastic injection. When the hull 4 is used for protection of fuel leaks, the material used for molding is preferably polyamide, capable of withstanding high temperatures.
Selon ce mode de réalisation, la coque 4 et le raccord 3 ont une forme sensiblement complémentaire, la coque 4 présentant une forme générale coudée adaptée à un raccord 3 coudé. Les éléments de protection 41 ,42 sont symétriques par rapport à l'axe ZZ'. Ainsi, chaque élément de protection 41 ,42 a une forme générale sensiblement semi cylindrique, concave, apte à recouvrir et à protéger le raccord 3. Cette forme coudée est donnée à titre d'exemple non limitatif, la coque 4 pouvant par exemple être droite. La forme de la coque 4 est apte à recevoir un raccord 3, les éléments de protection 41 ,42 étant conformés en fonction des dimensions du raccord 3.According to this embodiment, the shell 4 and the coupling 3 have a substantially complementary shape, the shell 4 having a generally bent shape adapted to a fitting 3 bent. The protection elements 41, 42 are symmetrical with respect to the axis ZZ '. Thus, each protection element 41, 42 has a generally semi-cylindrical, concave shape, capable of covering and protecting the connector 3. This angled shape is given by way of non-limiting example, the shell 4 may for example be straight . The shape of the shell 4 is able to receive a coupling 3, the protection elements 41, 42 being shaped according to the dimensions of the coupling 3.
La coque 4 comporte un moyen d'évacuation des fuites 413 apte à permettre un écoulement des fuites vers l'extérieur. A cet effet, une extrémité 412 de l'élément de protection 41 du côté du tuyau 2 prolonge en direction de l'axe YY' l'élément de protection 41 de manière à délimiter une première ouverture demi circulaire. De même une extrémité 422 de l'élément de protection 42 du côté du tuyau 2 prolonge en direction de l'axe YY' l'élément de protection 42, délimitant ainsi une deuxième ouverture demi circulaire. Les deux demi ouvertures circulaires sont ainsi en retrait par rapport à l'extrémité extérieure de la coque 4. Les éléments de protection 41 ,42 comportent respectivement une portion d'appuiThe shell 4 comprises a leak evacuation means 413 capable of allowing leakage to flow outwards. For this purpose, an end 412 of the protective element 41 on the side of the pipe 2 extends in the direction of the axis YY 'the protection element 41 so as to define a first half-circular opening. Similarly, an end 422 of the protection element 42 on the pipe 2 side extends in the direction of the axis YY 'the protection element 42, thus delimiting a second semi-circular opening. The two circular half-openings are thus set back with respect to the outer end of the shell 4. The protection elements 41, 42 respectively comprise a bearing portion
431 ,432 sensiblement plane formant un rebord périphérique sensiblement plan, appelé également plan de joint 431 ,432. Les portions d'appui 431 et 432 sont symétriques entre elle par rapport à l'axe vertical ZZ' et sont ainsi aptes à être en contact l'une 431 avec l'autre 432. Les deux éléments de protection 41 ,42 sont articulés au moyen d'une charnière ou charnière film 44 telle que représentée sur les figures 3 et 4. Cette articulation relie une extrémité 410 du premier élément de protection 41 et une extrémité 420 du deuxième élément 42 pour permettre la rotation entre eux autour de l'axe vertical ZZ'. Des cordons de joints par exemple, non représentés sur les figures, peuvent être disposés sur le plan de joint 431 ,432 afin de permettre une étanchéité lors de la fermeture des deux éléments de protection 41 ,42. Les éléments de protection 41 ,42 forment ainsi des demi coques 41 ,42, la demi coque 41 étant sensiblement l'image réfléchie de la demi coque 42 symétriquement par rapport à l'axe vertical ZZ' de la coque 4. Le raccord 3, une fois placé à l'intérieur de l'élément de protection 41 par exemple est recouvert par l'élément de protection 42, les portions d'appui 431 ,432 étant en contact l'une sur l'autre. L'extrémité 412,422 de la coque 4 délimite ainsi une ouverture circulaire 413 formée par la première et la deuxième demi ouverture circulaire citées ci-dessus, apte à entourer et à laisser passer le tuyau. Le diamètre de l'ouverture circulaire 413 est supérieur au diamètre du tuyau 2 de manière à permettre à la fois le passage du tuyau 2 et l'écoulement d'éventuelles fuites. L'ouverture circulaire 413 est prévue pour entourer le tuyau 2 circulaire d'une façon concentrique, toutefois il sera compris que cette forme est donnée à titre d'exemple non limitatif et qu'elle peut être rectangulaire ou autre, le but étant à la fois de faire passer le tuyau 2 et d'éventuelles fuites vers l'extérieur de la coque 4, l'ouverture 413 ayant une largeur supérieure à la largeur extérieure du tuyau 2 pour permettre l'écoulement des fuites vers l'extérieur. L'espace libre présent entre la coque 4 et le raccord 3 est de préférence minimum de façon à réduire au maximum l'encombrement environnant le raccord 3 et la coque 4.431, 432 substantially planar forming a substantially planar peripheral rim, also called joint plane 431, 432. The bearing portions 431 and 432 are symmetrical with respect to the vertical axis ZZ 'and are thus able to be in contact 431 with the other 432. The two protection elements 41, 42 are articulated to the means of a hinge or film hinge 44 as shown in Figures 3 and 4. This joint connects an end 410 of the first protection element 41 and an end 420 of the second member 42 to allow rotation between them about the axis vertical ZZ '. Joint cords for example, not shown in the figures, may be arranged on the joint plane 431, 432 to allow sealing during closing of the two protective elements 41, 42. The protection elements 41, 42 thus form half-shells 41, 42, the half-shell 41 being substantially the reflected image of the half-shell 42 symmetrically with respect to the vertical axis ZZ 'of the shell 4. The connector 3, once placed inside the protective element 41 for example is covered by the protective element 42, the bearing portions 431, 432 being in contact with one another. The end 412,422 of the shell 4 thus delimits a circular opening 413 formed by the first and second circular half-opening mentioned above, able to surround and let the pipe pass. The diameter of the circular opening 413 is greater than the diameter of the pipe 2 so as to allow both the passage of the pipe 2 and the flow of any leaks. The circular opening 413 is provided to surround the circular pipe 2 in a concentric manner, however it will be understood that this form is given by way of non-limiting example and that it may be rectangular or otherwise, the purpose being to time to pass the pipe 2 and possible leakage to the outside of the shell 4, the opening 413 having a width greater than the outer width of the pipe 2 to allow the flow of leakage to the outside. The free space present between the shell 4 and the coupling 3 is preferably minimum so as to reduce as much as possible the space surrounding the coupling 3 and the shell 4.
Les deux éléments de protections 41 ,42 sont maintenus l'un à l'autre par exemple par des moyens de fixations ou fermeture tels que dispositifs de clips, ou des vis non représentés sur les figures.The two protector elements 41, 42 are held together by, for example, fastening or closing means such as clip devices, or screws not shown in the figures.
Les éléments de protection 41 ,42 comportent respectivement des moyens de serrage 414,416,424,415,426,425 aptes à serrer le tuyau 2 et à le maintenir sensiblement au centre de l'ouverture circulaire 413. Les moyens de serrage 414,415,416,424,425,426 peuvent appartenir à l'un des éléments de protection 41 ou 42 ou aux deux éléments de protection 41 et 42.The protection elements 41, 42 respectively comprise clamping means 414, 414, 244, 415, 426, 425 able to clamp the pipe 2 and to maintain it substantially in the center of the circular opening 413. The clamping means 414, 415, 414, 244, 425, 426 may belong to one of the protection elements. or 42 or both protection elements 41 and 42.
Conformément à un premier mode de réalisation de la figure 3, deux demi supports supérieur 415 et inférieur 416 en forme de demi parenthèses fermées symétriques par rapport à l'axe horizontal XX' sont localisés à la périphérie des partie supérieure et inférieure de la demi ouverture circulaire de l'élément de protection 41. Les demi supports 415,416 sont venus de matière avec l'élément de protection 41 et sont prolongés symétriquement respectivement par deux demi supports supérieur 425 et inférieur 426 par rapport à l'axe vertical ZZ'. Deux membranes ou languettes 414,424 en forme de parenthèses ouvertes symétriques par rapport à l'axe vertical ZZ', relient respectivement l'extrémité gauche du support supérieur 415,425 à l'extrémité gauche du support inférieur 416,426 d'une part, et l'extrémité droite du support supérieur 415,425 à l'extrémité droite du support inférieur 416,426. Les membranes 414,424 sont venus de matière avec respectivement chacun des deux supports 415,425 et 416,426 et sont dirigées, arquées, vers le centre de l'ouverture circulaire 413 de la coque 4, de manière à ménager un étranglement d'axe vertical ZZ' permettant de maintenir le tuyau 2 en position au centre de l'ouverture circulaire 413. Ainsi, une fois la coque 4 refermée sur le raccord 3, il est possible au tuyau 2 d'être maintenu serré par les moyens de serrage 414,416,424,415,426,425. Il sera compris que dans ce mode de réalisation, les moyens de serrage 414,416,424,415,426,425 peuvent être moulés indifféremment sur l'élément de protection 41 ou l'élément de protection 42. Dans un autre mode de réalisation et conformément à la figure 4, les éléments de protection 41 ,42 comportent respectivement des moyens de serrage 414,415,416 et 424,425,426 aptes à gripper le tuyau 2. Chaque membrane ou languette 414,424 est venue de matière avec respectivement un demi support 415, 416 et 425,426. Chaque demi support 415,416 d'une part et 425,426 d'autre part est venu de matière avec respectivement l'élément de protection 41 et l'élément de protection 42.According to a first embodiment of FIG. 3, two upper half-supports 415 and lower 416 in the form of half closed parentheses symmetrical with respect to the horizontal axis XX 'are located at the periphery of the upper and lower portions of the half-opening The half supports 415,416 are integral with the protection element 41 and are symmetrically extended respectively by two upper half-supports 425 and lower 426 with respect to the vertical axis ZZ '. Two diaphragms or tabs 414,424 in the form of open parentheses symmetrical with respect to the vertical axis ZZ 'respectively connect the left end of the upper support 415,425 to the left end of the lower support 416,426 on the one hand, and the right end top bracket 415,425 at the right end of the bracket lower 416.426. The membranes 414, 424 are made of material with respectively each of the two supports 415, 425 and 416, 426 and are directed, arcuate, towards the center of the circular opening 413 of the shell 4, so as to provide a vertical axis constriction ZZ 'allowing keep the pipe 2 in position in the center of the circular opening 413. Thus, once the shell 4 closed on the connector 3, it is possible for the pipe 2 to be held tight by the clamping means 414, 414, 244, 415, 426, 425. It will be understood that in this embodiment, the clamping means 414, 414, 244, 415, 426, 425 may be molded indifferently on the protection element 41 or the protection element 42. In another embodiment and in accordance with FIG. 4, the elements of FIG. protection 41, 42 respectively comprise clamping means 414, 415, 416 and 424, 425, 426 able to grip the pipe 2. Each membrane or tongue 414, 424 is integrally formed with a half support 415, 416 and 425, 426, respectively. Each half support 415,416 on the one hand and 425,426 on the other hand is integral with respectively the protection element 41 and the protection element 42.
Chacune des deux membranes 414,424 arquée vers le centre de l'ouverture circulaire 413 de la coque 4, est alors fixée sur deux points de l'élément de protection 41 ,42 associé. Les moyens de serrage 414,415,416 et 424,425,426 sont ainsi dans ce mode de réalisation des éléments intégrés aux éléments de protection 41 ,42 par exemple par moulage et comportent ainsi deux membranes ou flasques, appartenant chacune à un élément de protection 41 ,42.Each of the two membranes 414,424 arched towards the center of the circular opening 413 of the shell 4, is then fixed on two points of the protective element 41, 42 associated. In this embodiment, the clamping means 414, 415, 416 and 424, 425, 426 are elements integrated in the protection elements 41, 42, for example by molding, and thus comprise two membranes or flanges, each belonging to a protection element 41, 42.
Il sera compris que les moyens de serrage ci-dessus sont donnés à titre d'exemple non limitatifs et peuvent également être des éléments rapportés aux éléments de protection 41 ,42 non moulés en même temps que ceux-ci, ou encore être directement fixés ou venus de matière avec les éléments de protections 41 ,42 sans supports 415,416,425,426.It will be understood that the above clamping means are given by way of non-limiting example and may also be elements attached to the protection elements 41, 42 not molded at the same time as these, or else be directly attached or integrally with the protective elements 41, 42 without supports 415,416,425,426.
Les moyens de serrage 414,416,424,415,426,425 permettent alors de maintenir le tuyau au centre de l'ouverture circulaire 413 tout en maintenant une ouverture autour dudit tuyau de façon à permettre un écoulement d'éventuelles fuites de liquide. Ainsi le tuyau 2 est à distance de l'ouverture circulaire 413, l'espace entre l'ouverture circulaire 413 et le tuyau n'étant pas obturé.The clamping means 414, 414, 244, 415, 426, 425 then make it possible to keep the pipe at the center of the circular opening 413 while maintaining an opening around said pipe so as to allow a flow of any leakage of liquid. Thus the pipe 2 is at a distance from the circular opening 413, the space between the circular opening 413 and the pipe not being closed.
Conformément aux figures 1 à 4, la coque 4, coudée, comporte une deuxième ouverture 417 apte à l'écoulement des fuites du côté du raccord 3 reliant la rampe d'injection 1. La forme de cette ouverture 417 est conformée à une liaison entre le raccord 3 et la rampe d'injection 1. Il sera compris que lorsque le raccord 3 relie par exemple deux tuyaux, cette deuxième ouverture 417 peut être analogue à l'ouverture circulaire 413 précédemment décrite et peut comporter des moyens de serrage identiques à ceux de l'ouverture circulaire 413. Les diamètres des ouvertures circulaires, ainsi que les dimensions des moyens de serrage étant adaptés aux tuyaux utilisés. Ainsi, une telle coque peut avantageusement être utilisée pour la protection des raccords de tuyaux d'un véhicule, pour des liquides tels que du carburant, du liquide permettant de laver les vitres ou encore de l'huile, ou de liquide de refroidissement. Une telle coque 4 permet avantageusement de diriger d'éventuelles fuites de liquides vers une zone connue telle que par exemple le sol, en dessous du véhicule, ne comportant pas de risques.According to FIGS. 1 to 4, the hull 4, bent, comprises a second opening 417 capable of flowing leaks on the side of the connector 3 connecting the injection manifold 1. The shape of this opening 417 is shaped as a connection between the connection 3 and the injection rail 1. It will be understood that when the connector 3 connects for example two pipes, this second opening 417 may be similar to the circular opening 413 previously described and may comprise clamping means identical to those of the circular opening 413. The diameters of the circular openings, as well as the dimensions of the clamping means being adapted to the pipes used. Thus, such a shell can advantageously be used for protecting the pipe connections of a vehicle, for liquids such as fuel, liquid for washing the windows or oil, or coolant. Such a hull 4 advantageously makes it possible to direct possible leakage of liquids to a known area such as, for example, the ground below the vehicle, which does not involve any risk.
La coque 4 peut par exemple être prolongée le long de l'axe du ou des tuyaux, jusqu'à un emplacement approprié, sans risque, où les éventuelles fuites de liquide peuvent être dirigées.The shell 4 may for example be extended along the axis of the pipe or pipes, to a suitable location, without risk, where possible liquid leakage can be directed.
La coque présente avantageusement une extrémité ouverte vers l'extérieur permettant seulement de diriger les fuites vers une direction connue sans les récupérer mais peut également comporter d'autres ouvertures localisées en fonction de la direction que l'on souhaite faire prendre au fluide. L'utilisation d'une telle coque permet avantageusement qu'une fuite de carburant ou encore qu'une fuite de liquide de refroidissement ou de lave glace par exemple n'asperge pas un turbocompresseur, ou un collecteur d'échappement, permettant d'éviter un choc thermique par exemple.The shell advantageously has an open end outwardly allowing only to direct the leaks to a known direction without recovering them but may also include other openings located according to the direction that it is desired to make the fluid take. The use of such a shell advantageously allows a fuel leak or a leak of coolant or ice wash for example does not spray a turbocharger, or an exhaust manifold, to avoid a thermal shock for example.
Les éléments de protection 41 ,42 sont conformés en fonction des dimensions du raccord 3, et peuvent avantageusement s'adapter à plusieurs types de raccord.The protective elements 41, 42 are shaped according to the dimensions of the connector 3, and can advantageously adapt to several types of connection.
Une telle coquille peut ainsi être utilisée aussi bien pour des véhicules dont le carburant est l'essence mais également pour les véhicules utilisant le diesel. Pour les moteurs diesel, les raccords étant plus volumineux, il suffit alors d'utiliser des coques ayant sensiblement une même forme générale que celle décrite précédemment mais avec des dimensions adaptées.Such a shell can thus be used both for vehicles whose fuel is gasoline but also for vehicles using diesel. For diesel engines, the connections being larger, it is then sufficient to use shells having substantially the same general shape as that described above but with suitable dimensions.
Par ailleurs, il existe un nombre non négligeable de raccords normalisés, et une coque selon l'invention peut être rendue standard de manière à pouvoir être utilisée pour plusieurs types de raccord. Furthermore, there is a non-negligible number of standardized connectors, and a shell according to the invention can be made standard so that it can be used for several types of connection.
