L'invention concerne un dispositif de circulation de lubrifiant pour véhicule automobile, et notamment un refroidisseur de lubrifiant intégrant un tel dispositif. Elle concerne aussi un procédé de fabrication d'un tel dispositif de circulation de lubrifiant. Enfin, elle porte aussi sur un véhicule automobile comprenant un tel dispositif de circulation de lubrifiant.

It also relates to a method of manufacturing such a lubricant circulation device. Finally, it also relates to a motor vehicle comprising such a lubricant circulation device.
Le document WO2009/059678 représente un dispositif de circulation d'huile intégré dans un refroidisseur d'huile qui repose sur un assemblage de tôles. Ce refroidisseur comprend un dispositif de circulation d'huile comprenant un clapet formé par une lame élastique pour fermer ou ouvrir un conduit d'huile. L'inconvénient d'une telle solution est qu'elle entraîne un risque de déformation trop importante de cette lame formant le clapet, qui peut être soumise à des fortes pressions d'huile, qui entraîne des problèmes d'étanchéité et la présence de fuites d'huile. The document WO2009 / 059678 represents an oil circulation device integrated in an oil cooler which rests on a sheet assembly. This cooler comprises an oil circulation device comprising a valve formed by an elastic blade for closing or opening an oil pipe. The disadvantage of such a solution is that it involves a risk of excessive deformation of the blade forming the valve, which can be subjected to high oil pressure, which causes sealing problems and the presence of leaks oil.
Ainsi, un objet général de l'invention est de proposer une solution de circulation de lubrifiant pour véhicule automobile qui ne présente pas l'inconvénient de l'état de la technique, qui permet d'assurer l'étanchéité durable au niveau de son clapet d'ouverture et fermeture. Thus, a general object of the invention is to provide a lubricant circulation solution for a motor vehicle that does not have the disadvantage of the state of the art, which makes it possible to ensure durable sealing at its valve. opening and closing.
A cet effet, l'invention repose sur un dispositif de circulation de lubrifiant comprenant un clapet se présentant sous la forme d'une lame élastique, caractérisé en ce qu'il comprend une butée liée au clapet limitant l'amplitude d'ouverture du clapet. For this purpose, the invention is based on a lubricant circulation device comprising a valve in the form of an elastic blade, characterized in that it comprises an abutment linked to the valve limiting the opening amplitude of the valve. .
Le clapet peut comprendre une extension dont une extrémité remplit la fonction de butée. L'extension peut présenter une forme de crochet s'étendant dans une direction opposée au sens d'ouverture du clapet. The valve may comprise an extension, one end of which serves as a stop. The extension may have a hook shape extending in a direction opposite to the opening direction of the valve.
L'extension peut être une languette dont l'extrémité coopère avec une fenêtre dont un montant supérieur limite l'amplitude de mouvement de l'extrémité de l'extension et donc du clapet. The extension may be a tongue whose end cooperates with a window whose upper amount limits the range of movement of the end of the extension and therefore the valve.
L'invention porte aussi sur un refroidisseur de lubrifiant pour véhicule automobile, caractérisé en ce qu'il comprend un dispositif de circulation de lubrifiant tel que décrit précédemment. The invention also relates to a lubricant cooler for a motor vehicle, characterized in that it comprises a lubricant circulation device as described above.
Le clapet peut être aménagé au niveau d'une surface interface du refroidisseur. Le refroidisseur de lubrifiant peut comprendre plusieurs plaques empilées, dont une ouverture reçoit une extension en forme de crochet du clapet, une plaque présentant une partie particulière coopérant avec l'extrémité du crochet pour former une butée. L'invention porte aussi sur un véhicule automobile caractérisé en ce qu'il comprend un dispositif de circulation de lubrifiant tel que décrit précédemment. The valve can be arranged at an interface surface of the cooler. The lubricant cooler may comprise a plurality of stacked plates, an opening of which receives a hook-shaped extension of the valve, a plate having a particular portion cooperating with the end of the hook to form a stop. The invention also relates to a motor vehicle characterized in that it comprises a lubricant circulation device as described above.
Le dispositif de circulation de lubrifiant peut être disposé sur un refroidisseur de lubrifiant lié au carter moteur du véhicule automobile. The lubricant circulation device can be arranged on a lubricant cooler connected to the motor vehicle crankcase.
L'invention porte aussi sur un procédé de fabrication d'un dispositif de circulation de lubrifiant tel que décrit précédemment, caractérisé en ce qu'il comprend la découpe et le pliage d'une lame élastique comprenant une extension formant une butée. Le procédé de fabrication d'un dispositif de circulation de lubrifiant peut comprendre une étape de découpe dans une même plaque du clapet, de son extension et d'une fenêtre, puis une étape de pliage à sensiblement 90 degrés de la fenêtre pour que son montant supérieur vienne coopérer avec l'extrémité de l'extension pour former une butée. The invention also relates to a method of manufacturing a lubricant circulation device as described above, characterized in that it comprises the cutting and folding of an elastic blade comprising an extension forming a stop. The manufacturing method of a lubricant circulation device may comprise a cutting step in the same plate of the valve, of its extension and of a window, then a step of folding at substantially 90 degrees of the window so that its amount the upper end cooperates with the end of the extension to form a stop.
Ces objets, caractéristiques et avantages de la présente invention seront exposés en détail dans la description suivante de modes d'exécution particuliers faits à titre non-limitatif en relation avec les figures jointes parmi lesquelles : These objects, features and advantages of the present invention will be set forth in detail in the following description of particular embodiments given in a non-limiting manner in relation to the appended figures among which:
La figure 1 représente une vue en perspective d'une partie de refroidisseur de lubrifiant de véhicule automobile intégrant un dispositif de circulation selon un premier mode d'exécution de l'invention. FIG. 1 represents a perspective view of a motor vehicle lubricant cooler part incorporating a circulation device according to a first embodiment of the invention.
Les figures 2a et 2b représentent en perspective des grossissements de détails du dispositif de circulation selon le premier mode d'exécution de l'invention. Figures 2a and 2b show in perspective magnifications of details of the circulation device according to the first embodiment of the invention.
La figure 3 représente en perspective une tôle selon une étape de fabrication d'un dispositif de circulation selon un second mode d'exécution de l'invention. La figure 4 représente une vue en perspective d'une partie de refroidisseur de lubrifiant de véhicule automobile intégrant un dispositif de circulation selon le second mode d'exécution de l'invention. Le concept de l'invention consiste en un dispositif de circulation pour fluide de lubrification comprenant un clapet intégrant une butée de sorte de limiter son débattement pour empêcher sa déformation trop importante. Les figures 1 , 2a et 2b représentent une partie d'un refroidisseur d'huile de véhicule automobile selon un premier mode d'exécution de l'invention. Ce refroidisseur comprend une structure composée d'un empilement de plaques 2. Un clapet 4 se présentant sous la forme d'une lame métallique est disposé au niveau de la face supérieure 3 du refroidisseur, de sorte de servir d'interface entre le refroidisseur et un autre composant du véhicule automobile auquel il est relié, par exemple le carter cylindre du moteur. Le clapet 4 est fabriqué à partir d'une lame d'acier ressort, faite par découpe et pliage, par un outillage monté sur des presses. Il est prolongé par une extension 5 en forme de crochet, comprenant une première partie horizontale puis une seconde partie s'étendant vers l'intérieur du refroidisseur, dans la direction opposée à celle d'ouverture du clapet. L'extrémité inférieure 6 du crochet vient coopérer avec une partie 7 d'une plaque complémentaire pour former une butée limitant le débattement du clapet 4. En effet, l'ouverture du clapet 4 est obtenue par sa déformation élastique vers le haut, entraînant le crochet 5 dans ce mouvement vertical. Au-delà d'une certaine remontée, son extrémité 6 vient en butée contre la partie 7 de la plaque, ce qui empêche le clapet de continuer de s'ouvrir, limite donc son angle d'ouverture. Ainsi, même si le clapet 4 est soumis à des pressions de fluide très élevées, il ne va pas se déformer au-delà d'une amplitude limite prédéfinie, par l'écartement entre l'extrémité 6 du crochet 5 et la partie 7 de la plaque en position fermée du clapet 4, garantissant le maintien durable de sa fonction élastique. Les figures 1 , 2a et 2b illustrent le clapet en position fermée. La plaque supérieure formant la butée présente une forme particulière, une partie 7, coopérant avec le crochet 5, différente des autres plaques 8 empilées, au niveau d'une ouverture 9. En variante, ces plaques peuvent présenter d'autres géométries et l'extension 5 formant la butée peut de même présenter d'autres formes et dimensions sans sortir du concept de l'invention. L'invention porte aussi sur un procédé de fabrication d'un dispositif de circulation de lubrifiant qui comprend la découpe et le pliage d'une lame élastique comprenant une extension formant une butée. 3 shows in perspective a sheet according to a step of manufacturing a circulation device according to a second embodiment of the invention. FIG. 4 represents a perspective view of a motor vehicle lubricant cooler part incorporating a circulation device according to the second embodiment of the invention. The concept of the invention consists of a circulation device for lubricating fluid comprising a valve incorporating a stop so as to limit its movement to prevent excessive deformation. Figures 1, 2a and 2b show a portion of a motor vehicle oil cooler according to a first embodiment of the invention. This cooler comprises a structure composed of a stack of plates 2. A valve 4 in the form of a metal blade is disposed at the upper face 3 of the cooler, so as to act as an interface between the cooler and another component of the motor vehicle to which it is connected, for example the cylinder block of the engine. The valve 4 is made from a spring steel blade, made by cutting and folding, by a tool mounted on presses. It is extended by a hook-shaped extension 5, comprising a first horizontal part then a second part extending towards the inside of the cooler, in the direction opposite to that of opening the valve. The lower end 6 of the hook cooperates with a portion 7 of a complementary plate to form a stop limiting the deflection of the valve 4. In fact, the opening of the valve 4 is obtained by its elastic deformation upwards, resulting in the hook 5 in this vertical movement. Beyond a certain rise, its end 6 abuts against the part 7 of the plate, which prevents the valve from continuing to open, thus limiting its opening angle. Thus, even if the valve 4 is subjected to very high fluid pressures, it will not deform beyond a predefined limit amplitude, by the distance between the end 6 of the hook 5 and the portion 7 of the plate in the closed position of the valve 4, ensuring the durable maintenance of its elastic function. Figures 1, 2a and 2b illustrate the valve in the closed position. The upper plate forming the stop has a particular shape, a part 7, cooperating with the hook 5, different from the other plates 8 stacked at a As a variant, these plates may have other geometries and the extension 5 forming the abutment may likewise have other shapes and dimensions without departing from the concept of the invention. The invention also relates to a method of manufacturing a lubricant circulation device which comprises cutting and folding an elastic blade comprising an extension forming a stop.
Les figures 3 et 4 illustrent un second mode d'exécution de l'invention. La figure 3 représente une plaque 13 métallique dans laquelle les éléments destinés à former le dispositif de circulation pour lubrifiant sont prédécoupés. Une partie est obtenue après pliage à environ 90 degrés d'une partie prédécoupée qui forme une fenêtre dont le montant supérieur 17 participe à la fonction de butée. En effet, le clapet 14 comprend une extension 15 sous forme d'une languette, qui vient se positionner à l'intérieur de cette fenêtre, de sorte que son extrémité 16 forme une butée en coopération avec le montant 17. Comme dans le précédent mode d'exécution, l'amplitude d'ouverture du clapet 14 est limitée, ce qui garantit son fonctionnement durable dans sa limite élastique. Ce mode d'exécution présente l'avantage de permettre la formation de la butée et du clapet sur une même pièce, ce qui est simple et économique. Cette même pièce peut être la plaque supérieure de la structure du refroidisseur ou une plaque distincte, qui vient s'ajouter à la structure du refroidisseur. Si un refroidisseur est équipé de ce dispositif de circulation de lubrifiant, et est monté sur le carter d'un moteur, il est nécessaire de prévoir une ouverture dans la structure du carter pour recevoir la fenêtre de la butée. Figures 3 and 4 illustrate a second embodiment of the invention. Fig. 3 shows a metal plate 13 in which the elements for forming the lubricant circulation device are pre-cut. A portion is obtained after folding about 90 degrees of a pre-cut portion which forms a window whose upper amount 17 participates in the stop function. Indeed, the valve 14 comprises an extension 15 in the form of a tongue, which is positioned inside this window, so that its end 16 forms a stop in cooperation with the amount 17. As in the previous mode execution, the opening amplitude of the valve 14 is limited, which ensures its sustainable operation in its elastic limit. This embodiment has the advantage of allowing the formation of the abutment and the valve on the same part, which is simple and economical. This same piece can be the top plate of the cooler structure or a separate plate, which is added to the structure of the cooler. If a cooler is equipped with this lubricant circulation device, and is mounted on the housing of an engine, it is necessary to provide an opening in the housing structure to receive the window of the stop.
Dans le cas de ce second mode d'exécution de l'invention, le procédé de fabrication comprend une étape de découpe dans une même plaque du clapet 14, de son extension 15 et d'une fenêtre, puis une étape de pliage à sensiblement 90 degrés de la fenêtre pour que son montant supérieur 17 vienne coopérer avec l'extrémité 16 de l'extension 15 pour former une butée. Naturellement, l'invention ne se limite pas aux modes d'exécution décrits et la butée peut être formée par d'autres moyens et constructions, par exemple à partir de toute extension du clapet. Avantageusement, la butée et le clapet forment un même composant, sont indissociables, la butée étant aménagée sur une partie du clapet lui-même. En variante, la butée peut être un élément distinct lié au clapet, par exemple par toute fixation mécanique, collage... De plus, le dispositif de circulation de lubrifiant a été illustré dans le cas d'une utilisation dans un refroidisseur mais il est naturellement possible de l'utiliser dans tout autre dispositif comprenant une circulation de lubrifiant. In the case of this second embodiment of the invention, the manufacturing method comprises a cutting step in the same plate of the valve 14, its extension 15 and a window, then a folding step at substantially 90 degrees of the window so that its upper amount 17 comes to cooperate with the end 16 of the extension 15 to form a stop. Naturally, the invention is not limited to the embodiments described and the stop may be formed by other means and constructions, for example from any extension of the valve. Advantageously, the abutment and the valve form a single component, are inseparable, the abutment being arranged on a portion of the valve itself. Alternatively, the stop may be a separate element related to the valve, for example by any mechanical fastening, bonding ... In addition, the lubricant circulation device has been illustrated in the case of use in a cooler but it is naturally possible to use it in any other device including a circulation of lubricant.
