Un moteur à combustion interne comporte de man ière classique dans sa partie inférieure appelée également bas moteur, un bloc cyl indre et un carter d'hu ile. Une pompe à hu ile, entraînée par un vilebrequ in , aspire l'hu ile stockée dans le fond du carter d'hu ile pour l'envoyer, à travers une crépine de pompe à hu ile, vers des éléments mobiles du moteur tels que par exemple les pal iers de vilebrequins, les bielles ou les pistons. L'hu ile retourne ensu ite par gravité dans le carter d'huile.The invention more specifically relates to an oil sump of an internal combustion engine having means forming a stick for the passage of oil adapted to maintain a pump pump to oil immersed in the oil. An internal combustion engine has a conventional manner in its lower part also called low engine, a cyl indre block and a crankcase.

The oil then returns by gravity to the sump.
Lors de son fonctionnement, le moteur produ it des vibrations qui se propagent et sont susceptibles de créer des bruits parasites dans le moteur. Pour atténuer le bruit rayonné par le carter d'hu ile et rigid ifier le bas moteur, il est connu de renforcer la structure du carter d'huile par des nervures de rig id ification et/ou de rajouter une plaque anti-déjaugeage sensiblement horizontale fixée dans le carter d'hu ile. Cependant, une telle plaque anti-déjaugeage ne permet pas à la fois de rig idifier le bas moteur et de créer une zone de stabil isation du volume d'huile pour l imiter les effets que peuvent provoquer des dévers sur le déjaugeage.During operation, the engine generates vibrations that propagate and are likely to create spurious noise in the engine. In order to attenuate the noise radiated by the oil sump and to stiffen the low engine, it is known to reinforce the structure of the oil sump with stiffening ribs and / or to add a substantially horizontal anti-lift plate. fixed in the oil pan. However, such anti-lift plate does not allow both to idify the low engine and to create an oil volume stabilization zone to mimic the effects that cant may have on the plane.

D'autres caractéristiques et avantages de l'invention apparaîtront clairement à la lecture de la description suivante du mode de réalisation non limitatif de celle-ci, en liaison avec les dessins annexés sur lesquels : - la figure 1 représente une coupe transversale du carter d'huile selon l'invention. Dans la suite de la description, on adoptera à titre non limitatif une orientation longitudinale, verticale et transversale selon le trièdre direct L, V, T rapporté à l'orientation du moteur. Conformément à la figure 1, seuls les éléments du moteur nécessaires à la compréhension de l'invention ont été figurés.Other features and advantages of the invention will become clear from reading the following description of the nonlimiting embodiment thereof, in conjunction with the accompanying drawings in which: - Figure 1 shows a cross section of the housing of the oil according to the invention. In the remainder of the description, a longitudinal, vertical and transverse orientation will be adopted in a nonlimiting manner according to the direct trihedron L, V, T relative to the orientation of the motor. According to Figure 1, only the engine elements necessary for understanding the invention have been figured.
Le carter d'huile 1, tel que représenté sur la figure 1, est réalisé en forme de réservoir ou bac comportant un fond pouvant être légèrement incliné. Le carter d'huile 1 comporte un fond 21 et des parois latérales. Les parois latérales sont constituées de deux parois latérales longitudinales 220 et de deux parois latérales transversales 221.The oil sump 1, as shown in Figure 1, is designed in the form of a tank or tank having a bottom that can be slightly inclined. The oil sump 1 has a bottom 21 and side walls. The side walls consist of two longitudinal side walls 220 and two transverse side walls 221.
Le carter d'huile 1 est destiné à contenir l'huile nécessaire à la lubrification des éléments mobiles du moteur. Cette huile est pompée depuis le carter d'huile 1 par l'intermédiaire de la crépine de pompe à huile 3, elle-même reliée à une pompe à huile non représentée sur la figure 1. L'huile utilisée s'écoule ensuite par gravité depuis les éléments mobiles, ou fixes du moteur vers le carter d'hu ile 1 dans lequel elle est récupérée.The oil sump 1 is intended to contain the oil necessary for lubricating the moving parts of the engine. This oil is pumped from the oil sump 1 via the oil pump strainer 3, itself connected to an oil pump not shown in FIG. 1. The oil used then flows through gravity from the movable elements, or fixed from the engine to the oil pan 1 in which it is recovered.
Le carter d'hu ile 1 comporte une plaque anti-déjaugeage 2. La plaque anti-déjaugeage 2 est fixée au carter d'huile 1 par exemple sur une des parois latérales long itud inales 220, et s'étend parallèlement au fond 21 du carter d'huile 1 sensiblement jusqu'aux parois latérales du carter d'hu ile 1 . Ainsi une fois placé dans le véhicule, le fond du carter d'hu ile 1 est parallèle au sol et la plaque anti-déjaugeage 2 est parallèle au fond du carter d'hu ile 1 et au sol . La plaque anti-déjaugeage 2 divise ainsi le carter d'hu ile 1 en une chambre 23 comprise entre le bord supérieur des parois 22 du carter d'huile 1 et la plaque anti-déjaugeage 2 d'une part, et en un réservoir 24 constituant la partie inférieure du carter d'hu ile 1 en forme de bac. La plaque anti-déjaugeage 2 évite d'une part que l'hu ile contenue dans le carter d'huile 1 n'entre en contact avec des éléments mobiles tels que par exemple le vilebrequ in, permet de l imiter le mouvement de la nappe d'hu ile dans le carter et donc le déjaugeage et l'émulsion , et permet de rigidifier les parois du carter d'hu ile 1 .The oil pan 1 comprises an anti-lift plate 2. The anti-lift plate 2 is fixed to the oil sump 1, for example on one of the longitudinal longitudinal walls 220, and extends parallel to the bottom 21 of the oil pan 1 substantially to the side walls of the oil pan 1. Thus, once placed in the vehicle, the bottom of the oil pan 1 is parallel to the ground and the anti-lift plate 2 is parallel to the bottom of the oil pan 1 and the ground. The anti-lift plate 2 thus divides the oil pan 1 into a chamber 23 between the upper edge of the walls 22 of the oil sump 1 and the anti-lift plate 2 on the one hand, and a tank 24 constituting the lower part of the tank-shaped housing 1. The anti-lift plate 2 avoids, on the one hand, that the oil contained in the oil sump 1 coming into contact with moving elements such as, for example, the crankshaft, makes it possible to imitate the movement of the water table. of oil in the housing and thus the planing and the emulsion, and makes it possible to stiffen the walls of the oil pan 1.
La plaque anti-déjaugeage 2 comporte une cavité 25 permettant le passage d'une crépine de pompe à huile 3 dans le réservoir 24 du carter d'hu ile 1 .The anti-lift plate 2 comprises a cavity 25 allowing the passage of an oil pump strainer 3 in the tank 24 of the oil pan 1.
Le carter d'huile 1 comporte des moyens 10, 20 formant une chicane pour le passage de l'huile sont adaptés à maintenir la crépine de pompe à huile 3 toujours immergée dans l'hu ile, sous la plaque anti-déjaugeage 2, dans le réservoir 24. Les moyens 1 0, 20 comportent un premier moyen 1 0 et un deuxième moyen 20 appartenant respectivement au carter d'hu ile 1 et à la plaque anti- déjaugeage 2.The oil sump 1 comprises means 10, 20 forming a baffle for the passage of the oil are adapted to maintain the oil pump strainer 3 always immersed in the oil, under the anti-lift plate 2, in the reservoir 24. The means 1 0, 20 comprise a first means 1 0 and a second means 20 respectively belonging to the oil casing 1 and to the anti-squatting plate 2.
Ces moyens 1 0, 20 formant une chicane pour le passage de l'huile sont de préférence de forme sensiblement cyl indrique. Selon le mode de réalisation de la figure 1 , un premier cylindre 10 est intégré dans le carter d'huile 1 , et un deuxième cylindre 20 est intégré dans la plaque anti-déjaugeage 2. Il sera compris que ce mode de réalisation n'est donné qu'à titre d'exemple non limitatif, et que ces cylindres 10, 20 peuvent par exemple être des éléments rapportés respectivement au carter d'huile 1 et à la plaque anti- déjaugeage 2. L'un des moyens 10, 20 peut être un élément intégré tandis que l'autre moyen peut être un élément rapporté.These means 1 0, 20 forming a baffle for the passage of the oil are preferably of substantially cylindrical shape. according to the embodiment of Figure 1, a first cylinder 10 is integrated in the oil sump 1, and a second cylinder 20 is integrated in the anti-squat plate 2. It will be understood that this embodiment is not given As a nonlimiting example, and these cylinders 10, 20 may for example be elements respectively reported to the oil sump 1 and to the anti-squat plate 2. One of the means 10, 20 may be an integrated element while the other means can be a reported element.
Le premier cylindre 10 s'étend, selon la direction verticale, du fond 21 du carter d'huile 1 vers la plaque anti-déjaugeage 2, et comporte par exemple des ouvertures 1 1 au niveau du fond 21 du carter d'huile 1 sur des tronçons du premier cylindre 10. Les ouvertures 1 1 s'étendent avantageusement dans l'axe longitudinal du véhicule afin que l'huile ne s'échappe pas et reste dans la chicane lors des virages, des accélérations ou lors du freinage par exemple. Le nombre d'ouvertures 1 1 peut être différent, le premier cylindre 10 peut comporter par exemple une ouverture 1 1 sur un tronçon qui s'étend parallèlement à une des deux parois latérales longitudinales 220 selon l'axe longitudinal du véhicule, et une ouverture 1 1 sur le tronçon qui s'étend parallèlement à l'autre paroi latéral longitudinale 220 opposée.The first cylinder 10 extends, in the vertical direction, the bottom 21 of the oil sump 1 to the anti-lift plate 2, and for example comprises openings 1 1 at the bottom 21 of the oil sump 1 on sections of the first cylinder 10. The openings 1 1 advantageously extend in the longitudinal axis of the vehicle so that the oil does not escape and remains in the baffle during turns, acceleration or braking for example. The number of openings 1 1 may be different, the first cylinder 10 may comprise for example an opening January 1 on a section which extends parallel to one of the two longitudinal side walls 220 along the longitudinal axis of the vehicle, and an opening 1 1 on the section which extends parallel to the other longitudinal side wall 220 opposite.
Le premier cylindre 10 permet avantageusement de rigidifier le fond 21 du carter d'huile.The first cylinder 10 advantageously makes it possible to stiffen the bottom 21 of the oil sump.
Le deuxième cylindre 20 est intégré à la plaque anti- déjaugeage 2. Il prolonge en continu la cavité 25 de la plaque anti- déjaugeage 2, et s'étend selon la direction verticale, de la plaque anti-déjaugeage 2 vers le fond 21 du carter d'huile 1 .The second cylinder 20 is integrated with the anti-squat plate 2. It continuously extends the cavity 25 of the anti-squat plate 2, and extends in the vertical direction, from the anti-squat plate 2 to the bottom 21 of the oil pan 1.
Le premier cylindre 10 et le deuxième cylindre 20 sont de diamètre sensiblement différents de sorte que le deuxième cylindre 20 de la plaque anti-déjaugeage 2 s'étend à l'intérieur du premier cylindre 10 du carter d'huile 1 . Ainsi tel que représenté sur la figure 1 , le premier cylindre 10 du carter d'huile 1 et le deuxième cylindre 20 de la plaque anti-déjaugeage 2 entourent la crépine de pompe à huile 3.The first cylinder 10 and the second cylinder 20 are of substantially different diameter so that the second cylinder 20 of the anti-lift plate 2 extends inside the first cylinder 10 of the oil sump 1. As shown in FIG. 1, the first cylinder 10 of the oil pan 1 and the second cylinder 20 of the anti-lift plate 2 surround the oil pump strainer 3.
La forme cyl indrique des moyens 1 0, 20 formant une chicane pour le passage d'huile est donnée à titre d'exemple non l imitatif. Leur forme peut par exemple être rectangulaire, ou autre. Il suffit que le moyen 20 de la plaque anti-déjaugeage 2 pu isse s'étendre à l'intérieur du moyen 10 du carter d'hu ile 1 d'une part et que la crépine de pompe à huile 3 puisse passer à l'intérieur du moyen 20 appartenant à la plaque anti-déjaugeage 2 d'autre part. Il sera compris que le moyen 20 de la plaque anti-déjaugeage 2 peut s'étendre à l'extérieur du moyen 10 du carter d'hu ile 1 , et que la crépine de pompe à huile 3 peut alors passer à l'intérieur du moyen 1 0 appartenant au carter d'huile 1 .The cylindrical form of the means 1, 20 forming a baffle for the oil passage is given as a non-imitative example. Their shape may for example be rectangular, or other. It suffices that the means 20 of the anti-lift plate 2 can extend inside the means 10 of the oil sump 1 on the one hand and that the oil pump strainer 3 can pass to the inside the means 20 belonging to the anti-lift plate 2 on the other hand. It will be understood that the means 20 of the anti-lift plate 2 can extend outside the means 10 of the oil pan 1, and that the oil pump strainer 3 can then pass inside the average 1 0 belonging to the oil sump 1.
Les extrémités inférieures du deuxième cyl indre 20 de la plaque anti-déjaugeage et les extrém ités inférieures de la crépine de pompe à hu ile 3 sont d istantes du fond 21 du carter d'hu ile 1 . Une d istance min imale d est à observer pour ne pas avoir de bruit d'aspiration lors du pompage d'hu ile et éviter ainsi toute interférence avec le carter d'hu ile 1 . Le deuxième cyl indre 20 de la plaque anti-déjaugeage 2 et la crépine de pompe à huile 3 s'étendant vers le fond du carter d'hu ile 1 ont de préférence sensiblement la même profondeur de man ière à ce que le volume d'hu ile à consommer soit le plus élevé possible . Toutefois cette d isposition n'est pas impérative. Le volume d'hu ile se déplace lors des accélérations, freinages, des virages gauche ou droit. On détermine un volume d'hu ile appelé « croisement de nappes » comme étant le volume d'hu ile formé par l'intersection des nappes d'huile lors des accélérations, freinages, des virages gauche et droit. Un tel carter d'hu ile permet à la crépine d'être local isée dans cette zone de croisement des nappes, ce qu i n'était pas toujours facile ou possible. En plaçant la crépine dans cette zone, on peut alors éviter, ou retarder le déjaugeage. Un tel carter d'huile permet que la chicane pour le passage de l'huile maintienne la crépine de pompe à huile 3 toujours immergée afin d'éviter tout déjaugeage. Le fluide est avantageusement maintenu à proximité de la crépine de pompe à huile 3 dans différentes positions du véhicule.The lower ends of the second cylinders 20 of the anti-lift plate and the lower ends of the oil pump strainer 3 are located in the bottom 21 of the oil pan 1. A minimum distance must be observed in order to avoid any suction noise when pumping oil and thus avoid any interference with the oil sump 1. The second cylinder 20 of the anti-lift plate 2 and the oil pump strainer 3 extending towards the bottom of the oil pan 1 preferably have substantially the same depth so that the volume of The best thing to eat is as high as possible. However, this provision is not imperative. The volume of oil moves during acceleration, braking, left or right turns. A volume of oil known as "crossover" is determined as the volume of oil formed by the intersection of the oil layers during acceleration, braking, left and right turns. Such an oil pan allows the strainer to be localized in this zone of cross-plies, which was not always easy or possible. By placing the strainer in this area, we can then avoid, or delay the planing. Such an oil pan allows the baffle for the passage of the oil to keep the oil pump strainer 3 always immersed in order to avoid any planing. The fluid is advantageously maintained near the oil pump strainer 3 in different positions of the vehicle.
Une telle chicane pour le passage d'huile limite avantageusement à la fois les bruits parasites provenant du fond 21 du carter d'huile, et permet à l'huile d'arriver avec un débit suffisant sans s'échapper dans le réservoir 24 du carter d'huile 1 lors de virages par exemple.Such a baffle for the oil passage advantageously limits both the parasitic noise from the bottom 21 of the oil sump, and allows the oil to arrive with a sufficient flow without escaping into the tank 24 of the sump oil 1 during turns for example.
Un tel carter d'huile permet de rigidifier le bas moteur non seulement par l'intermédiaire de la plaque anti-déjaugeage 2 qui renforce sa structure, mais également par l'intermédiaire du moyen 10 intégré à celui-ci. Un autre avantage de l'invention est également de permettre à la fois de rigidifier le bas moteur pour limiter le bruit rayonné dans le carter d'huile 1 et à la fois de créer une zone de stabilisation du volume d'huile pour limiter les effets des dévers sur le déjaugeage. Such an oil pan makes it possible to stiffen the low engine not only through the anti-lift plate 2 which reinforces its structure, but also via the means 10 integrated therewith. Another advantage of the invention is also to allow both to stiffen the low engine to limit the noise radiated in the oil sump 1 and both to create a zone of stabilization of the volume of oil to limit the effects cant on the plane.
