Description

BRIDE D'ALIMENTATION EN FLUIDE DE REFROIDISSEMENT POUR  COOLANT FLUID SUPPLY FLANGE FOR
COMPOSANT A REFROIDIR ET COMPOSANT EQUIPE D'UNE TELLE BRIDE  COOLING COMPONENT AND COMPONENT EQUIPPED WITH SUCH A FLANGE
L'invention concerne une bride d'alimentation en fluide de refroidissement pour un composant à refroidir, et un composant équipé d'une telle bride. Elle trouvera ses applications, notamment, comme bride d'alimentation en fluide de refroidissement d'une vanne de circuit d'air de moteur thermique. Au sens de l'invention, on désigne par « circuit d'air de moteur thermique » le circuit entre l'entrée d'admission et la sortie d'échappement du moteur thermique. La vanne peut être disposée dans le circuit d'admission, le circuit d'échappement, ou une boucle de recirculation par laquelle transitent les gaz d'échappement réinjectés à l'admission (EGR en anglais). The invention relates to a cooling fluid supply flange for a component to be cooled, and a component equipped with such a flange. It will find its applications, in particular, as a supply flange for cooling fluid of a thermal engine air circuit valve. For the purposes of the invention, the term "thermal engine air circuit" designates the circuit between the intake inlet and the exhaust outlet of the engine. The valve can be arranged in the intake circuit, the exhaust circuit, or a recirculation loop through which the exhaust gases fed back to the inlet (EGR in English) pass.
De manière générale, un système de recirculation des gaz d'échappement d'un moteur à combustion interne permet de diminuer la quantité d'oxydes d'azote présente dans les gaz d'échappement. Classiquement, un tel système de recirculation comporte un canal de dérivation sur la tubulure d'échappement des gaz, ce canal étant équipé d'une vanne de régulation de débit, dite vanne EGR, permettant de renvoyer à l'admission du moteur la quantité désirée de gaz d'échappement.  In general, an exhaust gas recirculation system of an internal combustion engine reduces the amount of nitrogen oxides present in the exhaust gas. Conventionally, such a recirculation system comprises a bypass channel on the gas exhaust pipe, this channel being equipped with a flow control valve, called the EGR valve, making it possible to return the desired quantity to the intake of the engine. exhaust gas.
Une telle vanne est donc parcourue par des gaz qui, même s'ils sont parfois refroidis avant de traverser la vanne, sont de températures très élevées. Il convient en conséquence de refroidir ladite vanne et il est connu en ce sens d'utiliser un liquide de refroidissement passant à travers un réseau de conduits parcourant la vanne.  Such a valve is traversed by gases which, even if they are sometimes cooled before crossing the valve, are very high temperatures. It is therefore appropriate to cool said valve and it is known in this sense to use a coolant passing through a network of conduits running through the valve.
Pour faire circuler le liquide dans la vanne, on utilise des brides d'entrée et/ou de sortie. Elles sont centrées sur les conduits de la vanne avec lesquelles elles communiquent par un fût favorisant la mise en place et le positionnement des brides sur la vanne.  In order to circulate the liquid in the valve, inlet and / or outlet flanges are used. They are centered on the conduits of the valve with which they communicate by a barrel favoring the establishment and the positioning of the flanges on the valve.
On a cependant constaté que le fût isolait le corps de vanne du circuit de refroidissement et créait localement un point chaud au voisinage de la bride. Un tel défaut de refroidissement est d'autant plus préjudiciable qu'il rend la vanne plus sensible aux phénomènes de dilatation thermique dans une zone qui devrait au contraire être placée à l'abri de ces phénomènes pour éviter d'altérer l'étanchéité et la fixation de la bride sur le corps.  However, it was found that the barrel insulated the valve body of the cooling circuit and created locally a hot spot near the flange. Such a cooling defect is all the more prejudicial that it makes the valve more sensitive to thermal expansion phenomena in an area that should instead be protected from these phenomena to avoid altering the seal and the fixing the flange on the body.
L'invention propose de remédier à ces problèmes en améliorant le refroidissement de la vanne à proximité de la bride sans perdre la fonctionnalité de centrage des brides de l'état de l'art.  The invention proposes to overcome these problems by improving the cooling of the valve near the flange without losing the centering functionality of the flanges of the state of the art.
L'invention se rapporte ainsi à une bride d'alimentation en fluide de refroidissement pour composant à refroidir, notamment une vanne, , ladite bride comprenant un fût de centrage dans un conduit de circulation dudit fluide de refroidissement dans ledit composant, ledit fût s'étendant selon une direction axiale, ledit fût étant parcouru par un canal de circulation dudit fluide de refroidissement s'étendant selon ladite direction axiale. Selon l'invention, ledit fût présente un ou des passages permettant une circulation transversale pour le fluide entre ledit conduit de circulation du composant et ledit canal de circulation de ladite bride. The invention thus relates to a cooling fluid supply flange for a component to be cooled, in particular a valve, said flange comprising a centering shaft in a duct for circulating said cooling fluid in said component, said cylinder being extending in an axial direction, said shaft being traversed by a circulation channel of said cooling fluid extending in said axial direction. According to the invention, said barrel has one or more passages allowing a transverse circulation for the fluid between said circulation duct of the component and said circulation channel of said flange.
On permet de la sorte un passage du liquide de refroidissement au contact d'une partie au moins des parois du composant à refroidir se trouvant en vis-à-vis du fût et on limite les phénomènes de réchauffement local à proximité de la bride. On évite ainsi de faire travailler la matière du composant à ce niveau ce qui renforce la fiabilité du montage de ladite bride à la fois en termes d'étanchéité et de tenue mécanique.  This allows a passage of the coolant in contact with at least a portion of the walls of the component to be cooled facing the barrel and limits the local warming phenomena in the vicinity of the flange. It is thus avoided to work the component material at this level which reinforces the reliability of mounting said flange both in terms of sealing and mechanical strength.
Selon différents modes de réalisation qui pourront être pris ensemble ou séparément :  According to different embodiments that can be taken together or separately:
- ledit canal débouche au niveau d'une extrémité distale du fût,  said channel opens at a distal end of the barrel,
- ledit fût est cylindrique, notamment de section circulaire,  said barrel is cylindrical, in particular of circular section,
- ladite bride comprend à la base du fût un épaulement configuré pour coopérer avec un joint destiné à réaliser une étanchéité entre ledit conduit de circulation du composant et l'extérieur du composant,  said flange comprises at the base of the shank a shoulder configured to cooperate with a seal intended to seal between said component circulation duct and the outside of the component,
- le ou lesdits passages sont situés entre ledit épaulement et ladite extrémité distale du fût, the passage or passages are located between said shoulder and said distal end of the barrel,
- le ou lesdits passages sont des fentes s'étendant selon la direction d'extension longitudinale du fût, the said passage or passages are slots extending in the direction of longitudinal extension of the shank,
- le ou lesdits passages sont ouverts axialement à l'extrémité distale du fût,  the passage or passages are open axially at the distal end of the barrel,
- le ou lesdits passages sont au nombre de trois, par exemple angulairement répartis à 120° les uns des autres,  the passage or passages are three in number, for example angularly distributed at 120 ° to one another,
- ledit fût comprend une paroi annulaire s'étendant autour de la direction axiale dans laquelle sont ménagés les passages, deux passages consécutifs définissant entre eux une branche,  said barrel comprises an annular wall extending around the axial direction in which the passages are formed, two consecutive passages defining between them a branch,
- ledit fût est muni de nervures de renfort, chaque nervure de renfort étant disposée dans ledit canal de circulation du fût depuis le centre du canal vers une branche,  - said barrel is provided with reinforcing ribs, each reinforcing rib being disposed in said barrel circulation channel from the center of the channel to a branch,
- lesdites nervures de renfort sont orientées selon la direction d'extension longitudinale dudit fût.  - Said reinforcing ribs are oriented in the direction of longitudinal extension of said barrel.
L'invention concerne également un composant à refroidir, notamment une vanne de circuit d'air de moteur thermique, telle qu'une vanne de recirculation de gaz d'échappement ou vanne EGR, comprenant un conduit de circulation d'un fluide de refroidissement et une bride telle que décrite plus haut pour le passage dudit fluide vers et/ou depuis ledit conduit.  The invention also relates to a component to be cooled, in particular a thermal engine air circuit valve, such as an exhaust gas recirculation valve or EGR valve, comprising a circulation duct for a cooling fluid and a flange as described above for the passage of said fluid to and / or from said conduit.
En variante, l'invention concerne une vanne d'un circuit de refroidissement d'un moteur thermique, comprenant un conduit de circulation du fluide de refroidissement et une bride telle que décrite plus haut pour le passage dudit fluide vers et/ou depuis ledit conduit.  In a variant, the invention relates to a valve of a cooling circuit of a heat engine, comprising a cooling fluid circulation duct and a flange as described above for the passage of said fluid to and / or from said duct. .
Ledit conduit est avantageusement évasé au droit dudit fût pour créer une chemise de circulation dudit fluide de refroidissement entre ledit fût et une paroi dudit conduit. Ladite paroi du conduit pourra comprendre une succession angulaire de nervures et de rainures pour limiter la surface de contact entre le fût et le composant. Lesdites nervures et/ou rainures sont, par exemple, orientées selon l 'longitudinale du fût. Avantageusement, seule la surface des rainures est usinée. Said duct is advantageously flared at the right of said barrel to create a jacket for circulating said cooling fluid between said barrel and a wall of said duct. Said wall of the duct may comprise an angular succession of ribs and grooves to limit the contact surface between the barrel and the component. Said ribs and / or grooves are, for example, oriented along the longitudinal axis of the barrel. Advantageously, only the surface of the grooves is machined.
D'autres caractéristiques et avantages de l'invention apparaîtront à la lecture de la description qui suit et qui se rapporte à des exemples détaillés de réalisation, en référence aux figures annexées qui représentent, respectivement :  Other features and advantages of the invention will appear on reading the description which follows and which relates to detailed examples of embodiment, with reference to the appended figures which represent, respectively:
- en figure 1, une vue en perspective, partielle, d'un exemple de réalisation d'une bride conforme à l'invention ;  - In Figure 1, a partial perspective view of an exemplary embodiment of a flange according to the invention;

- en figure 3, une vue en perspective du conduit de la vanne de la figure 2, illustré sans la bride.  - In Figure 3, a perspective view of the conduit of the valve of Figure 2, shown without the flange.
Comme illustré à la figure 1, l'invention concerne une bride 1 d'alimentation en fluide de refroidissement pour composant à refroidir, notamment composant de véhicule automobile. Il pourra en particulier s'agir d'une vanne de recirculation de gaz d'échappement. Une telle vanne est partiellement illustrée à la figure 2.  As illustrated in FIG. 1, the invention relates to a cooling fluid supply flange 1 for a component to be cooled, in particular a motor vehicle component. It may in particular be an exhaust gas recirculation valve. Such a valve is partially illustrated in FIG.
Ledit composant à refroidir est réalisé, par exemple, dans une structure ou corps 2 en fonderie, notamment en aluminium et/ou alliage d'aluminium.  Said component to be cooled is produced, for example, in a structure or body 2 in the foundry, in particular aluminum and / or aluminum alloy.
Dans le cas d'une vanne de recirculation de gaz d'échappement, ledit corps 2 comporte un conduit de circulation des gaz, non- visible. Un organe d'obturation de la vanne, telle une soupape ou volet, est configuré pour obturer plus ou moins ledit conduit de circulation des gaz de façon à permettre un réglage de leur débit à travers la vanne. Ladite vanne pourra comprendre des organes cinématiques, telle une pignonnerie à roue dentées, pour l'actionnement du ou desdits organes d'obturation depuis un moteur d'entraînement de la vanne. Elle pourra en outre comprendre des moyens de contrôle, notamment un capteur de positions, desdits organes cinématiques et/ou d'obturation.  In the case of an exhaust gas recirculation valve, said body 2 comprises a non-visible gas circulation duct. A shutter member of the valve, such as a valve or flap, is configured to more or less close said gas flow duct so as to allow an adjustment of their flow through the valve. Said valve may comprise kinematic members, such as a gear wheel gear, for actuating one or more shut-off members from a drive motor of the valve. It may further comprise control means, in particular a position sensor, said kinematic and / or shutter members.
De manière à autoriser son refroidissement, ledit composant comprend un réseau de passage d'un fluide de refroidissement, notamment de l'eau additionnée d'antigel, en particulier de glycol, provenant d'un circuit de refroidissement du véhicule. Ledit composant comprend au moins un conduit 4 de circulation dudit fluide de refroidissement par lequel celui-ci pénètre dans ledit composant et/ou sort dudit composant.  In order to allow its cooling, said component comprises a network for passing a cooling fluid, in particular water added with antifreeze, in particular glycol, originating from a cooling circuit of the vehicle. Said component comprises at least one duct 4 circulating said cooling fluid through which it enters said component and / or leaves said component.
Ladite bride 1 comprend un fût 3 de centrage dans ledit conduit de circulation 4 du fluide de refroidissement dans ledit composant. Ledit fût 3 s'étend selon une direction axiale D. Il définit un canal 5 de circulation dudit fluide de refroidissement s 'étendant selon ladite direction axiale D. Comme cela est plus visible à le figure 1, ledit fût 3 est, par exemple, cylindrique, notamment de section tranversale circulaire. Ledit canal de circulation 5 pourra lui aussi être de section circulaire de sorte que ledit fût 3 est formé d'une paroi annulaire 17. Ledit canal 5 débouche selon ladite direction axiale D, par exemple, au niveau d'une extrémité distale 1 1 du fût 3. Ledit fût 3 favorise l'introduction de la bride 1 dans le composant à refroidir ainsi que son bon positionnement vis-à-vis de celui-ci. Said flange 1 comprises a centering shaft 3 in said circulation duct 4 of the cooling fluid in said component. Said drum 3 extends in an axial direction D. It defines a channel 5 for circulating said cooling fluid extending in said axial direction D. As can be seen more clearly in FIG. 1, said barrel 3 is, for example, cylindrical, in particular of circular cross-section. Said circulation channel 5 may also be of circular section so that said shank 3 is formed of an annular wall 17. Said channel 5 opens in said axial direction D, for example, at a distal end 1 1 of the 3. The said barrel 3 promotes the introduction of the flange 1 in the component to be cooled and its good positioning vis-à-vis it.
A ce sujet, ladite bride 1 comprend ici une platine 7 de fixation audit composant. Ladite platine 7 est, par exemple, perpendiculaire audit fût 3. Elle pourra comprendre des orifices 9 de passage de vis de fixation, non-illustrées. De son côté, ledit composant à refroidir comprend, par exemple, des alésages 6 pour la fixation de ladite bride 1 sur ledit composant à refroidir par l'intermédiaire desdites vis.  In this regard, said flange 1 here comprises a plate 7 for fixing to said component. Said platen 7 is, for example, perpendicular to said barrel 3. It may comprise orifices 9 for fixing screws, not illustrated. For its part, said component to be cooled comprises, for example, bores 6 for fixing said flange 1 to said component to be cooled by means of said screws.
Par ailleurs ledit composant à refroidir pourra comprendre un joint 8 pour l'étanchéité entre ledit conduit 4 de circulation du fluide de refroidissement et l'extérieur du composant à refroidir. Ledit joint 8 est situé entre ladite bride 1 et ledit composant à refroidir et on comprend que l'étanchéité dépend, notamment, d'un bon positionnement de ladite bride 1 par rapport audit composant.  Furthermore, said component to be cooled may comprise a seal 8 for sealing between said cooling fluid circulation duct 4 and the outside of the component to be cooled. Said gasket 8 is located between said flange 1 and said component to be cooled and it is understood that the sealing depends, in particular, on a good positioning of said flange 1 with respect to said component.
Ladite bride 1 pourra comprendre, à la base du fût 3, un épaulement 15, configuré pour coopérer avec le joint 8. Ladite bride 1 pourra en outre bien sûr comprendre un ou des orifices de connexion, non-illustrés, au circuit de refroidissement alimentant ledit composant à refroidir. Said flange 1 may comprise, at the base of the shank 3, a shoulder 15, configured to cooperate with the gasket 8. Said flange 1 may furthermore of course comprise one or more connection orifices, not illustrated, to the cooling circuit feeding said component to be cooled.
Cela étant, selon l'invention, ledit fût 5 présente un ou des passages 13 permettant une circulation transversale pour le fluide entre ledit conduit 4 de circulation du composant et ledit canal 5 de circulation de ladite bride 1. Par transversale, on comprend une direction inclinée par rapport à la direction longitudinale du fût 3. That being so, according to the invention, said barrel 5 has one or more passages 13 allowing a transverse circulation for the fluid between said duct 4 for circulating the component and said channel 5 for flowing said flange 1. By transverse direction, a direction is understood inclined with respect to the longitudinal direction of the barrel 3.
Ledit fluide de refroidissement est ainsi dirigé non seulement vers l'extrémité distale 11 du fût 3 mais également vers une paroi 10 du conduit de circulation 6 se trouvant latéralement en vis-à- vis dudit fût 3. Ladite paroi 10 pourra en conséquence être elle aussi refroidie. On évite de la sorte la formation de points chauds subissant de forts phénomènes de dilation thermique faisant travailler la matière du corps 2 à proximité de la bride 1 et risquant de nuire à l'étanchéité apportée par ledit joint 8 ainsi qu'à la bonne liaison mécanique entre la bride 1 et le composant au niveau desdits alésages 6.  Said cooling fluid is thus directed not only towards the distal end 11 of the barrel 3, but also towards a wall 10 of the circulation duct 6 lying laterally opposite said barrel 3. Said wall 10 may consequently be also cooled. This avoids the formation of hot spots undergoing strong thermal expansion phenomena making work the body material 2 near the flange 1 and may affect the sealing provided by said seal 8 and the good connection between the flange 1 and the component at the level of said bores 6.
Le ou lesdits passages 13 sont situés, par exemple, entre ledit épaulement 15 et ladite extrémité distale 11 du fût 3. Le ou lesdits passages 13 sont ici des fentes s'étendant selon la direction d'extension longitudinale du fût, lesdites fentes 13 étant ouvertes axialement à l'extrémité distale 11 du fût 3. La ou lesdites fentes 13 sont ici au nombre de trois, régulièrement espacés. Lesdites fentes 13 sont séparées par des branches 19 dudit fût 3 s'étendant angulairement entre deux fentes 13 voisines dudit fût. Autrement dit, lesdites fentes 13 sont formées par des interruptions de la paroi annulaire 17 dudit fût 3. Ladite paroi annulaire 17 est ici définie par lesdites branches 19 qui sont prévues saillantes depuis l'épaulement 15. L'extrémité distale 11 du fût 3 est définie par une extrémité distale desdites branches 19. The at least one passage 13 is located, for example, between said shoulder 15 and said distal end 11 of the barrel 3. The at least one passage 13 is here slots extending in the direction of longitudinal extension of the barrel, said slots 13 being open axially at the distal end 11 of the barrel 3. The said slot or slots 13 are here three in number, regularly spaced. Said slots 13 are separated by branches 19 of said shank 3 extending angularly between two slots 13 neighbors of said barrel. In other words, said slots 13 are formed by interruptions of the annular wall 17 of said shank 3. Said annular wall 17 is here defined by said branches 19 which are provided projecting from the shoulder 15. The distal end 11 of the shank 3 is defined by a distal end of said branches 19.
Ledit fût 3 est avantageusement muni de nervures 21 de renfort, disposées dans ledit canal 5 de circulation du fût 3 entre les branches 19. Lesdites nervures de renfort 21 sont orientées, par exemple, selon la direction d'extension longitudinale D dudit fût 3, en particulier radialement. Elles sont ici au nombre de trois et disposées en étoile depuis la direction longitudinale dudit canal 5. Elles divisent de la sorte ledit canal 5 en trois sous canaux de passage du fluide de refroidissement.  Said drum 3 is advantageously provided with ribs 21 of reinforcement disposed in said channel 5 for circulation of the drum 3 between the branches 19. Said reinforcing ribs 21 are oriented, for example, along the direction of longitudinal extension D of said drum 3, in particular radially. They are here three in number and arranged in a star shape from the longitudinal direction of said channel 5. In this way, they divide said channel 5 into three subchannels for passing the cooling fluid.
Comme cela est plus visible à la figure 2, ledit conduit 4 est, par exemple, évasé au droit dudit fût 3 pour créer une chemise 12 de circulation dudit fluide de refroidissement entre ledit fût 3 et la paroi 10 dudit conduit 4.  As is more visible in FIG. 2, said duct 4 is, for example, flared to the right of said shank 3 to create a liner 12 for circulating said cooling fluid between said shank 3 and the wall 10 of said duct 4.
En se reportant à la figure 3, on constate que ladite paroi 10 du conduit 4 comprend, en particulier au niveau de ladite chemise 12, une succession angulaire de nervures 14 et de rainures 16 pour limiter la surface de contact entre le fût 3 et le composant à refroidir. Lesdites nervures 14 et/ ou rainure 16 présentent à l'une de leur extrémité longitudinale un épaulement 20 venant en regard de l'épaulement 15 de la bride 1, ledit joint 8 étant disposé entre lesdits épaulements 15, 20.  Referring to FIG. 3, it can be seen that said wall 10 of the duct 4 comprises, in particular at the level of said liner 12, an angular succession of ribs 14 and grooves 16 to limit the contact surface between the shank 3 and the component to cool. Said ribs 14 and / or groove 16 have at one of their longitudinal end a shoulder 20 coming opposite the shoulder 15 of the flange 1, said gasket 8 being disposed between said shoulders 15, 20.
Avantageusement, seules les faces desdites nervures 14 sont usinées tandis que l'état de surface desdites rainures 16 est conservée après fonderie.  Advantageously, only the faces of said ribs 14 are machined while the surface state of said grooves 16 is retained after casting.
Lesdites nervures 14 et/ou rainures 16 sont orientées, par exemple, selon la direction longitudinale du fût 3. Elles pourront présenter une forme sensiblement trapézoïdale, la grande base des nervures 14 étant située au niveau d'une même extrémité axiale de ladite chemise 12 que la petite base des rainures 16, et réciproquement à l'extrémité opposée.  Said ribs 14 and / or grooves 16 are oriented, for example, in the longitudinal direction of the shaft 3. They may have a substantially trapezoidal shape, the large base of the ribs 14 being located at the same axial end of said sleeve 12 the small base of the grooves 16, and vice versa at the opposite end.
On constate également à la figure 3 que ledit composant pourra comprendre une partie en saillie 18 du reste de son corps 2 au niveau de laquelle sont formés une embouchure dudit conduit de circulation 4 et/ou lesdits alésages 6.  It can also be seen in FIG. 3 that said component may comprise a projecting portion 18 of the rest of its body 2 at which a mouth of said circulation duct 4 and / or said bores 6 are formed.
