Description
L'invention concerne les dispositifs d'admission d'air pour les moteurs àThe invention relates to air intake devices for
combustion interne de véhicule.internal combustion of the vehicle.
On connaît un tel dispositif du document FR-2 757 569. Ce dispositif comprend un conduit muni d'un papillon dont la face extérieure est sphérique et la face intérieure cylindrique. Le papillon est monté mobile autour d'un axe de rotation de façon à pouvoir au choix obturer ou ouvrir le conduit. Such a device is known from the document FR-2 757 569. This device comprises a conduit provided with a butterfly whose outer face is spherical and the inner face cylindrical. The butterfly is movably mounted about an axis of rotation so that it can optionally close or open the conduit.
Un inconvénient de ce dispositif est que des condensas ont tendance à s'accumuler dans la partie basse du conduit et à bloquer la rotation du papillon. A disadvantage of this device is that condensates tend to accumulate in the lower part of the duct and block the rotation of the butterfly.
Un but de l'invention est de réduire les risques de blocage du dispositif par des condensas. An object of the invention is to reduce the risk of blockage of the device by condensates.
A cet effet, on prévoit selon l'invention un dispositif d'admission d'air pour un moteur, comprenant: - au moins un conduit; et - un boisseau mobile apte à obturer le conduit, le boisseau étant ouvert en partie inférieure. For this purpose, there is provided according to the invention an air intake device for an engine, comprising: - at least one duct; and - a movable plug adapted to close the conduit, the plug being open at the bottom.
Ainsi, en l'absence de partie inférieure dans le boisseau, on réduit les risques de coincement générés par l'encrassement du système. Thus, in the absence of a bottom portion in the bushel, the risk of jamming generated by fouling of the system is reduced.
Le dispositif selon l'invention pourra présenter en outre au moins l'une quelconque des caractéristiques suivantes: - le boisseau comprend une paroi latérale s'étendant d'un seul côté du boisseau; - le boisseau est relié au conduit d'un seul côté du conduit; - le boisseau est relié au conduit au-dessus du conduit; - le boisseau est monté mobile à rotation dans le conduit; et - le boisseau présente un axe de rotation vertical. The device according to the invention may also have at least one of the following characteristics: the plug comprises a lateral wall extending on one side of the plug; the plug is connected to the duct on one side of the duct; the bushel is connected to the duct above the duct; - The plug is rotatably mounted in the conduit; and the plug has a vertical axis of rotation.
On prévoit également selon l'invention un moteur comprenant un dispositif selon l'invention. The invention also provides an engine comprising a device according to the invention.
D'autres caractéristiques et avantages de l'invention apparaîtront encore dans la description suivante d'un mode préféré de réalisation donné à titre d'exemple non limitatif en référence aux dessins annexés sur lesquels: - la figure 1 est une vue en perspective d'un dispositif selon un mode préféré de réalisation de l'invention; - les figures 2 et 3 sont deux vues respectivement en élévation et de côté de l'un des boisseaux du dispositif de la figure 1 sans le corps du dispositif; - la figure 4 est une vue de dessus du dispositif de la figure 1 au niveau d'un des boisseaux; et - la figure 5 est une vue partielle en perspective analogue à la figure 1 montrant le boisseau en cours de mouvement. Other features and advantages of the invention will become apparent in the following description of a preferred embodiment given by way of non-limiting example with reference to the accompanying drawings in which: - Figure 1 is a perspective view of a device according to a preferred embodiment of the invention; - Figures 2 and 3 are two views respectively in elevation and side of one of the bushings of the device of Figure 1 without the body of the device; - Figure 4 is a top view of the device of Figure 1 at one of the bushels; and - Figure 5 is a partial perspective view similar to Figure 1 showing the bushel during movement.
On a illustré à la figure 1 un mode préféré de réalisation du dispositif d'admission d'air selon l'invention ou répartiteur 2. Ce dispositif est destiné à faire partie d'un moteur à combustion interne de véhicule, essence ou diesel. FIG. 1 illustrates a preferred embodiment of the air intake device according to the invention or distributor 2. This device is intended to be part of an internal combustion engine of a vehicle, petrol or diesel.
Le dispositif 2 comprend un corps 4 présentant plusieurs conduits 6, 8. Dans le présent exemple, il comprend quatre conduits 6 et quatre conduits 8 répartis par paires le long du dispositif et présentant chacun un axe horizontal 10, les axes étant parallèles entre eux et tous coplanaires. Les conduits 6 sont disposés en alternance avec les conduits 8. The device 2 comprises a body 4 having several ducts 6, 8. In the present example, it comprises four ducts 6 and four ducts 8 distributed in pairs along the device and each having a horizontal axis 10, the axes being parallel to each other and all coplanar. The ducts 6 are arranged alternately with the ducts 8.
A chaque conduit 6 est associé un boisseau 12 monté mobile à rotation par rapport au corps 4 autour d'un axe vertical 14. Each duct 6 is associated with a plug 12 mounted to rotate relative to the body 4 about a vertical axis 14.
Comme on le voit sur la figure 2, chaque boisseau 12 présente une tête 16 de forme générale cylindrique d'axe 14 présentant un étranglement 18 à mihauteur environ de la tête. Cet étranglement permet d'immobiliser la tête en translation verticale dans un logement de boisseau prévu dans le corps 4. As seen in Figure 2, each plug 12 has a generally cylindrical head 16 of axis 14 having a throat 18 approximately half of the head. This throttling makes it possible to immobilize the head in vertical translation in a bush housing provided in the body 4.
La tête du boisseau 12 est prolongée vers le bas par une paroi latérale gauche 20 s'étendant d'un seul côté de la tête, c'est-à-dire d'un seul côté de l'axe 14. Comme on l'observe sur les figures, le boisseau est dépourvu de paroi latérale droite en regard dé la paroi gauche 20. II est même dépourvu de parois avant et arrière au-dessous de la tête. Par conséquent, seul le quart de la périphérie de la tête est prolongé vers le bas sous la forme de la paroi latérale 20. Celle-ci a une forme cylindrique. Le boisseau est ouvert en partie inférieure, de sorte qu'il est dépourvu de paroi inférieure. The head of the plug 12 is extended downwardly by a left side wall 20 extending from one side of the head, that is to say one side of the axis 14. As it is observed in the figures, the bushel is devoid of right side wall facing the left wall 20. It is even devoid of front and rear walls below the head. Therefore, only a quarter of the periphery of the head is extended downwardly in the form of the side wall 20. This has a cylindrical shape. The bushel is open at the bottom, so that it has no bottom wall.
Le boisseau 12 est monté dans son logement au sein du corps 4, de sorte qu'une face inférieure 22 de la tête soit directement en regard d'une face inférieure 24 du conduit 6 associé. En l'espèce, le conduit a une section globalement rectangulaire dans un plan perpendiculaire à l'axe 10, à quatre faces, à savoir deux faces horizontales planes inférieure et supérieure et deux faces latérales planes gauche et droite. The plug 12 is mounted in its housing within the body 4, so that a lower face 22 of the head is directly facing a lower face 24 of the duct 6 associated. In this case, the duct has a generally rectangular section in a plane perpendicular to the axis 10, four faces, namely two lower and upper horizontal plane faces and two left and right plane lateral faces.
Le boisseau 12 est monté de sorte qu'il est mobile à rotation dans le conduit 4 entre une position dans laquelle la paroi latérale 20 occupe une cavité ménagée dans la paroi latérale gauche 26 du conduit et une position dans laquelle le boisseau, ayant pivoté d'un quart de tour autour de l'axe 14 conformément à la flèche 28 sur la figure 2, occupe une position dans laquelle la paroi 20 obture le conduit 6. Le système est particulièrement fiable. Le boisseau est monté et guidé à rotation au- dessus du conduit grâce à sa coopération de forme avec le corps 4. La réalisation pratique d'un tel montage en elle-même ne présente pas de difficulté et sera à la portée de l'homme du métier. Sur la figure 5, on a illustré le boisseau 12 en cours de rotation. The plug 12 is mounted so that it is rotatable in the duct 4 between a position in which the side wall 20 occupies a cavity formed in the left side wall 26 of the duct and a position in which the plug, pivoted d a quarter turn around the axis 14 according to the arrow 28 in Figure 2, occupies a position in which the wall 20 closes the duct 6. The system is particularly reliable. The plug is rotatably mounted and guided above the duct thanks to its shape cooperation with the body 4. The practical realization of such an assembly in itself presents no difficulty and will be within the reach of man of career. In Figure 5, there is illustrated the plug 12 during rotation.
La partie supérieure de la tête 16 émerge du corps 4 comme on le voit sur les figures. A chaque tête est fixé un bras 30 rigidement relié à la tête et présentant un doigt 32 relié en rotation à une tringle commune 34. Chacun des quatre boisseaux est ainsi relié à la tringle, de sorte que les quatre orifices peuvent être ouverts ou fermés ou voir leur section d'écoulement modifiée par une action commune sur la tringle 34. The upper part of the head 16 emerges from the body 4 as seen in the figures. At each head is fixed an arm 30 rigidly connected to the head and having a finger 32 rotatably connected to a common rod 34. Each of the four bushels is thus connected to the rod, so that the four orifices can be opened or closed or see their flow section modified by a common action on the rod 34.
Comme on le voit, lorsque l'un des boisseaux obture le conduit 6 correspondant, les conduits 8 adjacents ne sont pas obturés. As can be seen, when one of the plugs closes the corresponding duct 6, the adjacent ducts 8 are not closed.
Lorsque le boisseau est en position ouverte en laissant libre la section d'écoulement du conduit 6 associé, aucune perte de charge n'a lieu dans le conduit car aucune partie du boisseau ne s'étend dans la section d'écoulement. Même si des condensas s'accumulent dans la partie basse du conduit, la manoeuvre du boisseau n'est pas empêchée sachant que le boisseau est relié au conduit uniquement en partie supérieure du boisseau. On réduit ainsi les risques de coincement du système. When the plug is in the open position leaving free the flow section of the associated conduit 6, no pressure drop occurs in the conduit because no portion of the plug extends into the flow section. Even if condensates accumulate in the lower part of the duct, the operation of the bushel is not prevented knowing that the bushel is connected to the duct only in the upper part of the bushel. This reduces the risk of jamming the system.
Le présent dispositif est adapté à un moteur à quatre cylindres avec deux conduits d'admission 6,8 par poste ou par cylindre. The present device is adapted to a four-cylinder engine with two intake ducts 6.8 per station or per cylinder.
Bien entendu, on pourra apporter à l'invention de nombreuses modifications sans sortir du cadre de celle-ci. Of course, we can bring to the invention many changes without departing from the scope thereof.
On pourra mettre en oeuvre le fait que le boisseau est relié au conduit d'un seul côté du conduit indépendamment de la présence de l'ouverture en partie inférieure du boisseau. It will be possible to implement the fact that the plug is connected to the duct on one side of the duct independently of the presence of the opening in the lower part of the plug.
