Le gicleur d'huile 100 comprend un corps de gicleur 101.The
Le corps de gicleur 101 peut être fait de matière métallique. Par exemple, et de manière non limitative, le corps de gicleur 101 peut être fait d'acier.The
Le corps de gicleur 101 comprend une première extrémité 101a et une seconde extrémité 101b. La première extrémité présente une surface de contact 101d, et la seconde extrémité présente une surface exposée 101e. La surface de contact 101d et la surface exposée 101e sont reliées par une surface latérale 101c.The
La surface latérale 101c peut présenter une symétrie de révolution.The
Le corps de gicleur 101 comprend un canal axial 102, orienté selon l'axe XX' sur la
Le canal axial 102 débouche sur la surface de contact 101d du corps de gicleur 101. L'intersection du canal axial 102 avec la surface de contact 101d forme une ouverture appelée entrée d'huile 103. La surface de contact 101d du corps de gicleur 101 est destinée à être mise en contact avec un élément de surface du bloc moteur. L'élément de surface du bloc moteur comprend une amenée d'huile destinée à être mise en correspondance avec l'entrée d'huile 103.The
Le canal axial 102 peut également déboucher sur la seconde extrémité 101b.The
Le corps de gicleur 101 comprend également un canal latéral 104. Le canal latéral 104 communique avec le canal axial 102, et débouche sur la surface latérale 101c. L'intersection du canal latéral 104 avec la surface latérale 101c forme une ouverture appelée sortie d'huile 105.The
Le gicleur d'huile 100 comprend également une plaque d'orientation 106 (
Avantageusement, la plaque d'orientation 106 peut être faite de matière plastique, par exemple en un matériau thermoplastique chargé, avantageusement du polyamide chargé avec de la fibre de verre. Les matières plastiques présentent l'avantage de rendre le gicleur d'huile 100 plus léger que les gicleurs connus de l'état de la technique. Par ailleurs, une plaque d'orientation 106 en matière plastique, et plus particulièrement en matière thermoplastique, peut facilement être fabriquée par des procédés injection/moulage de manière répétable en grande série.Advantageously, the
La plaque d'orientation 106 peut être faite de tout matériau, par exemple un alliage de métal.The
La plaque d'orientation 106 comprend un trou 107 traversant de part en part la plaque d'orientation 106. Plus précisément, le trou 107 débouche sur la première face 106a et la seconde face 106b.The
Le trou 107 est destiné à loger le corps de gicleur 101. Plus particulièrement, le corps de gicleur 101 est monté en butée dans le trou 107 contre la première face 106a. Le montage en butée est réalisé par des moyens de butée. Les moyens de butée sont adaptés pour empêcher tout mouvement de la plaque d'orientation selon l'axe XX' du corps de gicleur 101 lorsque le gicleur 100 est monté sur le bloc d'un moteur par exemple.The
Le montage en butée peut être obtenu par un épaulement, dit premier épaulement 101f, de la surface latérale 101c du corps de gicleur 101.The abutment mounting can be obtained by a shoulder, called the
Dans un mode de réalisation avantageux présenté à la
Dans un autre mode de réalisation avantageux (
Le montage en butée du corps de gicleur 101 contre la première face 106a ne se limite pas à la formation d'épaulements. La surface latérale 101c et la surface intérieure 108 peuvent par exemple être de forme conique.The mounting of the
Nous verrons également dans la suite de la description, et en référence à la
En outre, selon l'invention, la surface de contact 101d du corps de gicleur 101 est en affleurement avec la seconde face 106b de la plaque d'orientation 106.Furthermore, according to the invention, the
Toujours selon l'invention, la plaque d'orientation 106 et le corps de gicleur 101 comprennent des premiers moyens d'orientation complémentaires de la sortie d'huile 105.Still according to the invention, the
Lesdits premiers moyens d'orientation complémentaires sont destinés à orienter la sortie d'huile 105 par rapport à la plaque d'orientation 106. La plaque d'orientation 106 comprend en outre des seconds moyens d'orientation destinés à orienter ladite plaque d'orientation 106 dans le bloc moteur.Said first complementary orientation means are intended to orient the
Ainsi, les premiers moyens d'orientation complémentaires et les seconds moyens d'orientation sont adaptés pour permettre l'orientation de la sortie d'huile 105 par rapport au bloc moteur.Thus, the first complementary orientation means and the second orientation means are adapted to allow the orientation of the
Nous allons maintenant décrire les premiers moyens d'orientation complémentaires.We will now describe the first complementary means of orientation.
Selon un premier mode de réalisation, les premiers moyens d'orientation complémentaires peuvent être formés par une surface intérieure 108 du trou 107 non circulaire (non représenté). Par exemple, la surface intérieure du trou 108 peut comprendre un ou plusieurs méplats. En complément, la section de surface latérale 101c du corps de gicleur 101 en contact avec la surface intérieure 108 du trou 107 peut également comprendre un ou plusieurs méplats destinés à être mis en correspondance avec le un ou plusieurs méplats de la surface intérieure 108 du trou 107. Ainsi, l'emboitement, méplat(s) contre méplat(s), du corps de gicleur 101 dans le trou 107 permettra l'orientation de la sortie d'huile 105 par rapport à la plaque d'orientation 106.According to a first embodiment, the first complementary orientation means can be formed by an
Selon un second mode de réalisation alternatif et/ou complémentaire, le corps de gicleur 101 peut comprendre un tube d'injection 112 (
Autrement dit, le tube d'injection 112 est guidé par les butées latérales. Les butées latérales peuvent par exemple être formées par une gorge d'accueil du tube d'injection 112 (
La plaque d'orientation 106 comprend également des seconds moyens d'orientation destinés à orienter ladite plaque 106 par rapport au bloc moteur. Les seconds moyens d'orientation, illustré à la
En variante, tel qu'illustré à la
Une forme complémentaire est également formée sur le bloc moteur, par exemple plat, destinée à coopérer avec le plat formé sur la surface latérale 106c de la plaque d'orientation 106.A complementary shape is also formed on the engine block, for example flat, intended to cooperate with the flat formed on the
Ainsi l'orientation de la plaque d'orientation 106 par rapport au bloc moteur, et l'orientation de la sortie d'huile 105 par rapport à ladite plaque 106 permet d'obtenir une orientation précise de la sortie d'huile 105 dans le bloc moteur.Thus the orientation of the
Les premiers moyens d'orientation complémentaires et les seconds moyens d'orientation ne nécessitent pas de brasage pour fixer l'orientation du corps de gicleur 101 par rapport à la plaque d'orientation 106 et par rapport au bloc moteur.The first complementary orientation means and the second orientation means do not require soldering to fix the orientation of the
Le gicleur 100 comprend également une vis de maintien 110, débouchant de la surface de contact 101d du corps de gicleur 101. La vis de maintien 110 est destinée à exercer un serrage étanche de la surface de contact 101d du corps du gicleur 101 contre le carter du moteur à combustion interne, et mettre en correspondance de manière étanche l'entrée d'huile 103 du corps de gicleur 101, et l'alimentation en huile dudit carter.The
De manière avantageuse, la vis de maintien 110 est montée de manière coaxiale au canal axial 102 de sorte qu'elle débouche de la surface de contact 101d du corps de gicleur 101 au niveau de l'entrée d'huile 103. Le serrage de la vis de maintien de le trou d'alimentation d'huile du moteur permet de maintenir le gicleur d'huile 100 en position stable.Advantageously, the retaining
La vis de maintien 110 est également adaptée pour permettre l'écoulement d'huile du trou d'alimentation du moteur vers le canal axial. A cette fin, une saignée 115 (
La vis de maintien peut traverser de part en part le corps de gicleur 101, de sa surface exposée 101e vers sa surface de contact 101d.The retaining screw can pass right through the
De manière alternative aux modes de réalisation des moyens de butée illustrés aux
De manière particulièrement avantageuse, le fait d'avoir la surface de contact 101d en affleurement avec la seconde face 106b de la plaque d'orientation 106 permet de minimiser les contraintes s'exerçant sur ladite plaque lorsque la vis de maintien 110 serre de manière étanche la surface de contact 101d du corps du gicleur 101 contre le carter d'un moteur à combustion interne.In a particularly advantageous manner, having the
Ainsi, la minimisation des contraintes sur ladite plaque permet l'emploi de matières plastiques, telles que des matériaux thermoplastiques chargées de fibre de verre. Par ailleurs, lors de l'emploi de matières plastiques pour la formation de la plaque d'orientation 106, le serrage de la vis de maintien peut être ajusté de sorte que la contrainte exercée sur ladite plaque 106 soit inférieure à la limite d'élasticité de la matière plastique.Thus, minimizing the stresses on said plate allows the use of plastics, such as thermoplastic materials loaded with glass fiber. Furthermore, when using plastics for the formation of the
En outre, l'utilisation d'une plaque d'orientation 106 en matière plastique n'a aucun effet sur la résistance mécanique et/ou la dégradation de la fonction du gicleur 100 selon l'invention.In addition, the use of an
Nous allons maintenant décrire le montage du gicleur 100 de la
Le montage comprend la fourniture du corps de gicleur 101. Le tube d'injection 112 est également alors introduit dans le trou sortie d'huile 105.The assembly includes the supply of the
L'ensemble tube d'injection 112/corps de gicleur 101 est alors brasé de manière à fixer de façon permanente et étanche le tube d'injection 112 au corps de gicleur 101. L'étape de brasage est exécutée par des techniques connues de l'homme du métier et n'est donc pas décrite dans la présente description.The
L'ensemble tube d'injection 112/corps de gicleur 101 est introduit dans le trou 107 par la première face 106a de la plaque d'orientation 106, et en butée contre ladite première face 106a. La fonction de butée est réalisée par le premier épaulement 101f, et éventuellement le second épaulement 107a décrits précédemment. L'orientation de la sortie d'huile 105 par rapport à la plaque d'orientation 106 est réalisée par les premiers moyens d'orientation complémentaires lors de l'insertion du corps de gicleur 101 dans le trou 107. L'orientation de la sortie d'huile peut, par exemple, être exécutée par la mise en place du tube d'injection 112 entre les deux butées latérales ou dans le gorge. Le tube d'injection 112 peut être plié de manière à orienter le jet d'huile.The
Enfin, l'ensemble comprenant le corps de gicleur 101, le tube d'injection 112 et la plaque d'orientation 106 peut alors être assemblé au bloc moteur de manière à mettre en correspondance de l'entrée d'huile 103 de la plaque d'orientation avec une l'alimentation en huile dudit moteur.Finally, the assembly comprising the
Lors de l'étape d'assemblage la plaque d'orientation 106 est orientée par rapport au carter du moteur à l'aide des seconds moyens d'orientation. L'ergot 109 est par exemple inséré dans un trou formé dans le carter du moteur.During the assembly step the
La vis de serrage 110 vient alors fixer de manière stable le gicleur ainsi formé.The clamping
Ce procédé de fabrication nécessite moins d'étapes d'assemblage par rapport aux gicleurs connus de l'état de la technique.This manufacturing process requires fewer assembly steps compared to the nozzles known from the prior art.
Par ailleurs, le gicleur 100 selon l'invention rend possible l'utilisation de matières plastiques pour la réalisation de la plaque d'orientation 106, ce qui permet de diminuer les coûts de production.Furthermore, the
