Description

La présente invention concerne un carter cylindres comportant une chambre d'eau destinés à équiper les moteurs à combustion notamment ceux des véhicules automobiles.The present invention relates to a cylinder block comprising a water chamber intended to equip combustion engines, in particular those of motor vehicles.

Les moteurs à combustion utilisant un liquide de refroidissement présentent des carters cylindriques avec des passages ou chambres d'eau de façon à faire circuler de l'eau ou tout autre liquide de refroidissement autour des cylindres pour en abaisser la température. La géométrie de la chambre, ainsi que les positions respectives des orifices d'entrée et de sortie ont donné lieu à de nombreux développement afin d'améliorer les échanges thermiques entre les cylindres et le liquide de refroidissement.Combustion engines using a coolant have cylindrical casings with water passages or chambers so as to circulate water or any other coolant around the cylinders to lower the temperature. The geometry of the chamber, as well as the respective positions of the inlet and outlet orifices have given rise to numerous developments in order to improve the heat exchanges between the cylinders and the coolant.

La demanderesse a développé une circulation originale dite en "trombone" décrite dans la demande de brevet FR-2.594.885 qui optimise ces échanges. La chambre d'eau est cloisonnée de sorte que le débit global de liquide de refroidissement balaie successivement les deux côtés longitudinaux du carter cylindres, avant de s'échapper.The applicant has developed an original circulation known as a "paper clip" described in patent application FR-2,594,885 which optimizes these exchanges. The water chamber is partitioned so that the overall flow of coolant successively scans the two longitudinal sides of the cylinder block before escaping.

Le cloisonnement de la chambre d'eau a été naturellement réalisé au moyen d'une nervure comme indiquée à la figure 4 de la demande de brevet précitée. Mais l'utilisation d'une telle nervure présente de nombreux inconvénients. En plus de la complexité de réalisation, ces nervures empêchent un correct refroidissement du cylindre sur lequel elles s'appuient, ce qui provoque une altération localisée de la chemise. Par ailleurs, la liaison mécanique ainsi établie entre le cylindre et le carter cylindres peut engendrer une déformation du cylindre.The partitioning of the water chamber was naturally carried out by means of a rib as indicated in FIG. 4 of the aforementioned patent application. However, the use of such a rib has many drawbacks. In addition to the complexity of production, these ribs prevent correct cooling of the cylinder on which they are supported, which causes localized alteration of the jacket. Furthermore, the mechanical connection thus established between the cylinder and the cylinder block can cause deformation of the cylinder.

Le document JP-A-57-124 057 qui constitue le document de l'état de la technique le plus proche de l'invention décrit l'utilisation d'une pièce oblongue destinée à être insérée dans un fourreau correspondant du carter cylindre pour venir obturer la chambre d'eau. Cette pièce oblongue est toutefois formée d'un barreau plein élastiquement compressible. L'utilisation d'un tel barreau obturateur élastiquement compressible a toutefois pour inconvénient de générer une discontinuité thermique et de créer des points chauds.The document JP-A-57-124 057 which constitutes the document of the state of the art closest to the invention describes the use of an oblong piece intended to be inserted in a corresponding sheath of the cylinder block to come close the water chamber. This oblong part is however formed of a solid bar which is elastically compressible. The use of such an elastically compressible shutter bar however has the drawback of generating thermal discontinuity and of creating hot spots.

La présente invention vise à pallier ces inconvénients et fournit un moyen simple susceptible de réaliser toute sorte de circulation d'eau.The present invention aims to overcome these drawbacks and provides a simple means capable of achieving any kind of water circulation.

Le carter cylindre, selon l'invention, comporte une chambre d'eau entourant les cylindres munie d'orifices d'arrivée et d'évacuation pour assurer une circulation de liquide de refroidissement, la chambre d'eau étant barrée par au moins une pièce oblongue insérée dans un fourreau formé dans le carter cylindre et intersectant la chambre d'eau de sorte que le liquide de refroidissement circule suivant un chemin prédéterminé entre les orifices d'arrivée et d'évacuation.The cylinder block, according to the invention, comprises a water chamber surrounding the cylinders provided with inlet and outlet orifices to ensure circulation of coolant, the water chamber being blocked by at least one part. oblong inserted in a sheath formed in the cylinder block and intersecting the water chamber so that the coolant circulates along a predetermined path between the inlet and outlet orifices.

Selon l'invention, le carter cylindre est caractérisé en ce que la pièce oblongue est réalisée en tôle pliée et en ce que la pièce oblongue permet le passage d'un certain débit de liquide de refroidissement.According to the invention, the cylinder block is characterized in that the oblong piece is made of folded sheet metal and in that the oblong piece allows the passage of a certain flow rate of coolant.

Selon une autre caractéristique du carter cylindre objet de l'invention, la pièce oblongue a ses bords latéraux incurvés de sorte que la section de la pièce soit sensiblement semi-cylindrique.According to another characteristic of the cylinder block object of the invention, the oblong part has its curved side edges so that the section of the part is substantially semi-cylindrical.

Selon une autre caractéristique du carter cylindre objet de l'invention, le fourreau a une largeur inférieure à celle de la pièce.According to another characteristic of the cylinder block object of the invention, the sleeve has a width less than that of the part.

Selon une autre caractéristique du carter cylindre objet de l'invention, la pièce est percée d'au moins une lumière assurant le débit de liquide.According to another characteristic of the cylinder block object of the invention, the part is pierced with at least one light ensuring the flow of liquid.

Selon une autre caractéristique du carter cylindre objet de l'invention, l'extrémité inférieure de la pièce se termine en pointe ce qui permet le passage d'un certain débit de liquide autour de cette pointe.According to another characteristic of the cylinder block object of the invention, the lower end of the part ends in a point which allows the passage of a certain flow of liquid around this point.

Selon une autre caractéristique du carter cylindre objet de l'invention, l'orifice d'introduction de la pièce défini dans la tablature soit de section inférieure à la section de fourreau et en ce que l'extrémité supérieure des bords latéraux puisse s'étendre sous la surface inférieure de la tablature.According to another characteristic of the cylinder block object of the invention, the insertion opening of the part defined in the tablature is of smaller section than the sheath section and in that the upper end of the side edges can extend under the lower surface of the tablature.

L'invention sera mieux comprise à l'étude de la description détaillée d'un mode de réalisation particulier de l'invention pris à titre nullementThe invention will be better understood on studying the detailed description of a particular embodiment of the invention taken in no way

l'invention pris à titre nullement limitatif et illustré par les dessins annexés, sur lesquels :

  • la figure 1 est une vue en perspective d'un dispositif obturateur,
  • la figure 2 est une vue en coupe longitudinale d'un carter cylindre montrant le positionnement du dispositif obturateur.
  • la figure 3 est une vue en perspective du carter cylindres avec un éclaté local au niveau de l'obturateur et montrant le trajet de la circulation d'eau en "trombone".
the invention taken without any limitation being implied and illustrated by the appended drawings, in which:
  • FIG. 1 is a perspective view of a shutter device,
  • Figure 2 is a longitudinal sectional view of a cylinder block showing the positioning of the shutter device.
  • Figure 3 is a perspective view of the cylinder block with a local exploded view at the shutter and showing the path of water circulation in "paper clip".

Conformément aux figures, le dispositif obturateur est constitué d'une pièce oblongue (1) en tôle pliée ou en tout autre matériau de caractéristiques similaires. Les bords latéraux (1a, 1b) de la pièce (1) sont incurvés de sorte que la section de la pièce soit sensiblement semi-cylindrique.According to the figures, the shutter device consists of an oblong piece (1) of folded sheet or any other material of similar characteristics. The lateral edges (1a, 1b) of the part (1) are curved so that the section of the part is substantially semi-cylindrical.

Cette pièce (1) est destinée à être insérée dans un orifice adapté de la tablature (9a) du carter cylindres (9) pour venir se loger dans un fourreau cylindrique (5) formé dans le carter cylindres (9) et intersectant la chambre d'eau (6), de façon à obstruer le passage du liquide de refroidissement. La largeur du fourreau (5) est inférieure à celle de la pièce (1), de sorte que les bords latéraux (1a, 1b) appuient en force sur les parois du fourreau (5). Cet agencement permet de bloquer en rotation la pièce (1) dans son logement (5). Dans la réalisation figurée, le carter cylindres (9) pour moteur quatre cylindres en ligne comporte une chambre d'eau (6) entourant les cylindres. L'orifice d'arrivée (7) est positionné à l'extrémité d'une face latérale, les orifices d'évacuation ou de montée d'eau (4) sont situés sur la face supérieure du carter, au voisinage de la face transversale immédiatement adjacente. Le dispositif obturateur est placé entre les orifices d'arrivée (7) et d'évacuation (4) sur le circuit le plus court. Ainsi, le liquide de refroidissement circule d'un côté des cylindres, puis de l'autre conformément au principe de la circulation en "trombone".This part (1) is intended to be inserted into an adapted orifice in the tablature (9a) of the cylinder block (9) to be housed in a cylindrical sheath (5) formed in the cylinder block (9) and intersecting the chamber d 'water (6), so as to obstruct the passage of the coolant. The width of the sleeve (5) is less than that of the part (1), so that the lateral edges (1a, 1b) press in force on the walls of the sleeve (5). This arrangement makes it possible to block the part (1) in rotation in its housing (5). In the illustrated embodiment, the cylinder housing (9) for an in-line four-cylinder engine has a water chamber (6) surrounding the cylinders. The inlet (7) is positioned at the end of a side face, the water outlet or rising ports (4) are located on the upper face of the housing, in the vicinity of the immediately adjacent transverse face. The shutter device is placed between the inlet (7) and outlet (4) ports on the shortest circuit. Thus, the coolant circulates on one side of the cylinders, then on the other in accordance with the principle of circulation in "paper clip".

Pour assurer le blocage axial dans le fourreau (5) de la pièce (1), cette dernière présente des découpes dans les extrémités supérieures des bords latéraux (1a, 1b). La hauteur de ces découpes est adaptée de façon que la nouvelle extrémité supérieure (1c) des bords latéraux se situe sous la tablature (9a) du carter cylindre, la pointe (3) de la pièce (1) en appui contre l'extrémité inférieure du fourreau cylindrique. Il suffit alors de dimensionner la section de l'orifice d'introduction légèrement inférieur à la section du fourreau cylindrique pour que la pièce oblongue (1) une fois en place, l'extrémité supérieure des bords latéraux est à même de venir en butée contre la surface inférieure de la tablature.To ensure axial locking in the sheath (5) of the part (1), the latter has cutouts in the upper ends of the lateral edges (1a, 1b). The height of these cutouts is adapted so that the new upper end (1c) of the lateral edges is located under the tablature (9a) of the cylinder block, the point (3) of the part (1) resting against the lower end cylindrical sheath. It then suffices to size the section of the introduction orifice slightly smaller than the section of the cylindrical sheath so that the oblong part (1) once in place, the upper end of the lateral edges is able to abut against the lower surface of the tablature.

Les zones de la chambre d'eau situées de part et d'autre du dispositif obturateur étant moins irriguée par le liquide de refroidissement, il apparaît préférable de créer un certain débit de liquide de refroidissement au travers de l'obturateur. Ce débit est réalisé grâce à la lumière (2) et aux passages autour de la pointe (3) formant l'extrémité inférieure de la pièce 1.The areas of the water chamber located on either side of the shutter device being less irrigated by the coolant, it appears preferable to create a certain flow of coolant through the shutter. This flow is achieved thanks to the lumen (2) and the passages around the point (3) forming the lower end of the part 1.

Grâce au dispositif obturateur selon l'invention, la mise en place d'une cloison dans une chambre d'eau peut être réalisée simplement. Il suffit de disposer d'un fourreau intersectant la chambre et d'y enfoncer la pièce obturatrice. Le fourreau peut être obtenu soit par perçage ou soit directement au moulage ; aucun critère d'état de surface particulier n'est imposé compte tenu du montage en force réalisé. Les caractéristiques physiques et mécaniques de la pièce obturatrice, en particulier sa conductibilité et sa flexibilité, et l'absence de liaison rigide entre le carter cylindres et le cylindre évitent les inconvénients des nervures précitées : les singularités mécaniques et thermiques s'exerçant sur le cylindre d'appui disparaissent.Thanks to the shutter device according to the invention, the installation of a partition in a water chamber can be carried out simply. All you need is an intersecting scabbard the room and push the shutter into it. The sheath can be obtained either by drilling or directly by molding; no particular surface condition criterion is imposed taking into account the strength assembly carried out. The physical and mechanical characteristics of the obturating part, in particular its conductivity and flexibility, and the absence of rigid connection between the cylinder block and the cylinder avoid the drawbacks of the aforementioned ribs: the mechanical and thermal singularities exerted on the cylinder support disappear.
