Description

<Desc/Clms Page number 1>
La présente invention concerne un système de raccord rapide de conduits d'air formant la ligne d'alimentation d'un moteur à combustion interne et reliant au moins certains équipements de cette ligne d'alimentation. <Desc / Clms Page number 1>
The present invention relates to a quick connection system of air ducts forming the supply line of an internal combustion engine and connecting at least some equipment of this supply line.

Actuellement, de manière générale, les conduits reliant les différents composants d'une ligne d'alimentation en air d'un moteur suralimenté (turbo) ou atmosphérique, c'est-à-dire l'ensemble comprenant le filtre à air, le cas échéant le turbo et l'échangeur ainsi que le boîtier du papillon et le répartiteur en amont du moteur, sont reliés par des systèmes à collier et vis avec interposition d'un joint. Ce système de raccord présente l'inconvénient d'être d'un assemblage relativement long à monter. Cela vaut pour le premier montage et la maintenance ou de réparation des composants de la ligne d'alimentation. Currently, in general, the conduits connecting the various components of an air supply line to a supercharged (turbo) or atmospheric engine, that is to say the assembly comprising the air filter, in the case if necessary the turbo and the exchanger as well as the throttle body and the distributor upstream of the engine, are connected by collar and screw systems with interposition of a seal. This connection system has the drawback of being a relatively long assembly. This applies to the first assembly and maintenance or repair of the components of the supply line.

La présente invention a pour but de simplifier l'assemblage en réduisant le nombre de pièces d'une ligne d'alimentation, de réduire le temps nécessaire à ces opérations, et donc permet de réduire le coût global. The object of the present invention is to simplify assembly by reducing the number of parts of a supply line, to reduce the time necessary for these operations, and therefore makes it possible to reduce the overall cost.

A cet effet, l'invention concerne un système de raccord du type défini ci-dessus, caractérisé en ce qu'il comprend, selon le sens de passage de l'air - un conduit amont, - un conduit aval, de même diamètre, le conduit aval étant prolongé vers l'amont par un manchon de diamètre intérieur supérieur au diamètre extérieur de l'extrémité du conduit amont, pour recevoir cette extrémité et former avec celle-ci une chambre annulaire, - un joint annulaire logé dans cette chambre annulaire et ayant des caractéristiques de filtre. To this end, the invention relates to a connection system of the type defined above, characterized in that it comprises, according to the direction of air flow - an upstream duct, - a downstream duct, of the same diameter, the downstream conduit being extended upstream by a sleeve with an inner diameter greater than the outer diameter of the end of the upstream conduit, to receive this end and form with it an annular chamber, - an annular seal housed in this annular chamber and having filter characteristics.

Contrairement à l'idée générale consistant à réaliser des assemblages étanches, la présente invention ne cherche pas à faire l'étanchéité absolue mais simplement à réaliser une étanchéité aéraulique en créant des pertes de charge suffisantes pour réduire au maximum une circulation d'air de l'extérieur vers l'intérieur à travers le joint- filtre. De plus, la différence de pression entre les deux extrémités du logement recevant le joint-filtre augmente, par Contrary to the general idea consisting in making watertight assemblies, the present invention does not seek to make absolute sealing but simply to achieve an air tightness by creating sufficient pressure drops to minimize air circulation from the outside to inside through the filter gasket. In addition, the pressure difference between the two ends of the housing receiving the filter seal increases, by

<Desc/Clms Page number 2><Desc / Clms Page number 2>

compression ou tassement du joint-filtre, les pertes de charge qu'il engendre.  compression or compaction of the filter seal, the pressure losses it generates.

Suivant une autre caractéristique avantageuse, le joint est collé ou monté en tension au manchon pour assurer sa tenue pendant la mise en place du conduit amont et éviter sa migration sous l'effet des éventuelles vibrations. According to another advantageous characteristic, the seal is glued or mounted in tension to the sleeve to ensure that it is held during the installation of the upstream duct and to prevent its migration under the effect of possible vibrations.

Les chicanes ainsi créées augmentent les pertes de charge au niveau du raccord en créant également une cavité dans laquelle le joint-filtre peut s'expanser et s'accrocher grâce à sa déformation. The baffles thus created increase the pressure losses at the level of the connection while also creating a cavity in which the filter-joint can expand and catch thanks to its deformation.

Suivant d'autres caractéristiques avantageuses, le conduit amont et le conduit aval avec son manchon sont réalisés en mousse de polyuréthane à cellules ouvertes notamment de densité 30kg/m3, au moins certains conduits sont en deux parties et au moins un conduit comporte un soufflet. According to other advantageous characteristics, the upstream conduit and the downstream conduit with its sleeve are made of polyurethane foam with open cells, in particular of density 30 kg / m 3, at least certain conduits are in two parts and at least one conduit comprises a bellows.

La présente invention sera décrite ci-après de manière plus détaillée à l'aide des dessins annexés dans lesquels - la figure 1 est une vue en coupe schématique d'un système de raccord selon l'invention, - la figure 2 montre une ligne d'alimentation d'un moteur turbo, munie de systèmes de raccord selon l'invention, - la figure 3 montre l'application de l'invention à une ligne d'alimentation d'un moteur atmosphérique. The present invention will be described below in more detail using the accompanying drawings in which - Figure 1 is a schematic sectional view of a coupling system according to the invention, - Figure 2 shows a line d 'supply of a turbo engine, provided with connection systems according to the invention, - Figure 3 shows the application of the invention to a supply line of an atmospheric engine.

Selon la figure 1, l'invention concerne un système de raccord de conduits formant une ligne d'alimentation d'un moteur turbo ou d'un moteur atmosphérique. Ce système se compose d'un conduit amont 1 et d'un conduit aval 2 considérés dans le sens de circulation A de l'air à travers la ligne d'alimentation. Le conduit amont 1 et le conduit aval 2 ont en général la même section. Le conduit aval 2 comporte un manchon 3 dont le diamètre intérieur ceint de la surface intérieure 31 est supérieur au diamètre extérieur cpext de l'extrémité 11 du conduit amont 1. L'extrémité 11 et le manchon 3 forment entre eux une chambre annulaire 4 recevant un joint-filtre 5. Ce joint-filtre 5 est en forme de manchon de section correspondant sensiblement à celle de la chambre 4 hormis sa compression. According to Figure 1, the invention relates to a duct connection system forming a supply line for a turbo engine or an atmospheric engine. This system consists of an upstream duct 1 and a downstream duct 2 considered in the direction of circulation A of the air through the supply line. The upstream conduit 1 and the downstream conduit 2 generally have the same section. The downstream conduit 2 comprises a sleeve 3 whose inner diameter surrounded by the inner surface 31 is greater than the outer diameter cpext of the end 11 of the upstream conduit 1. The end 11 and the sleeve 3 form between them an annular chamber 4 receiving a filter joint 5. This filter joint 5 is in the form of a sleeve with a section corresponding substantially to that of the chamber 4 except for its compression.

<Desc/Clms Page number 3><Desc / Clms Page number 3>

Suivant une caractéristique intéressante, la surface intérieure 31 du manchon 3 comporte des cavités 32, par exemple annulaires, ou discontinues mais réparties en quinconce sur toute la surface périphérique 31 pour créer des chicanes engendrant des pertes de charge.  According to an advantageous characteristic, the inner surface 31 of the sleeve 3 has cavities 32, for example annular, or discontinuous but distributed in staggered rows over the entire peripheral surface 31 to create baffles generating pressure losses.

Matière dans laquelle est réalisée le joint, définition du joint-filtre par sa porosité ou autres caractéristiques physiques. Material in which the seal is made, definition of the filter seal by its porosity or other physical characteristics.

Un exemple de matière dans laquelle est réalisé le joint-filtre, est une mousse polyuréthane à cellules ouvertes de densité 30kg/m3 L'extrémité avant 33 du manchon 3 est avantageusement de forme évasée pour faciliter l'emmanchement des deux parties 1, 2 ; 3 du système de raccord. An example of material in which the filter-seal is made, is an open-cell polyurethane foam with a density of 30 kg / m3. The front end 33 of the sleeve 3 is advantageously of flared shape to facilitate the fitting of the two parts 1, 2; 3 of the connection system.

La mise en place du raccord se fait par simple assemblage en jouant sur la souplesse des éléments ou en comprimant un éventuel soufflet de raccordement. Le démontage se fait dans les mêmes conditions. Dans certains cas, le joint-filtre peut être collé. The fitting is done by simple assembly by playing on the flexibility of the elements or by compressing a possible connecting bellows. Disassembly is done under the same conditions. In some cases, the filter gasket may be glued.

La figure 2 montre l'application du système de raccord à la ligne d'alimentation en air d'un moteur équipé d'un turbo. Cette ligne d'alimentation comprend un filtre 10, un turbo 11, un échangeur 12 en aval du turbo, un boîtier papillon 13 et un répartiteur 14 à l'entrée d'un moteur à combustion interne 15. Figure 2 shows the application of the connection system to the air supply line of an engine equipped with a turbo. This supply line comprises a filter 10, a turbo 11, an exchanger 12 downstream from the turbo, a throttle body 13 and a distributor 14 at the inlet of an internal combustion engine 15.

L'entrée de la ligne d'alimentation se compose par un conduit en général évasé formant un col d'entrée 20. Ce col d'entrée 20 est relié au filtre 10 par un raccord R1. Le filtre est relié au turbo par un conduit 21 à un ou deux raccords R2, R3. Le turbo 11 est relié à l'échangeur par un conduit 22 à un ou deux raccords R4, R5. L' échangeur 12 est relié au boîtier papillon 13 par un conduit 23 à un ou plusieurs raccords R6, R7. Enfin, le boîtier papillon 13 est relié au répartiteur 14 par un raccord R8. The inlet of the supply line is made up of a generally flared conduit forming an inlet neck 20. This inlet neck 20 is connected to the filter 10 by a connector R1. The filter is connected to the turbo by a conduit 21 to one or two connections R2, R3. The turbo 11 is connected to the exchanger by a conduit 22 to one or two connections R4, R5. The exchanger 12 is connected to the throttle body 13 by a conduit 23 to one or more connections R6, R7. Finally, the butterfly housing 13 is connected to the distributor 14 by a fitting R8.

Dans le cas du moteur atmosphérique représenté à la figure 3, la ligne d'alimentation se compose d'un filtre 10 et d'un boîtier papillon 13 reliés au répartiteur 14 et au moteur atmosphérique 15. Le col d'entrée 20 est là encore re- In the case of the naturally aspirated engine shown in Figure 3, the supply line consists of a filter 10 and a throttle body 13 connected to the distributor 14 and the atmospheric engine 15. The inlet neck 20 is there again re-

<Desc/Clms Page number 4><Desc / Clms Page number 4>

lié par un raccord R1 au filtre 10. Ce dernier est relié par un conduit 24 au boîtier papillon 13. Ce conduit est équipé de deux raccords R11, R12 et le boîtier papillon 13 est relié au répartiteur 14 par un raccord R8.  linked by a connector R1 to the filter 10. The latter is connected by a conduit 24 to the butterfly housing 13. This conduit is equipped with two connectors R11, R12 and the butterfly housing 13 is connected to the distributor 14 by a connector R8.

En conclusion, la liaison réalisée par les raccords des lignes d'alimentation est une liaison non étanche mais dont les fuites de l'extérieur vers l'intérieur sont filtrées si bien que l'air extérieur qui traverse éventuellement les raccords est filtré. Cet air de fuite, en quantité très faible, aura les mêmes caractéristiques que l'air circulant dans les conduits. In conclusion, the connection made by the connections of the supply lines is a leaktight connection but whose leaks from the outside to the inside are filtered so that the outside air which possibly crosses the fittings is filtered. This very small amount of leakage air will have the same characteristics as the air circulating in the conduits.

Selon l'architecture, il est possible de ne rien démonter pour extraire un conduit car on joue sur la souplesse. Les ou les conduits peuvent avoir des soufflets. Depending on the architecture, it is possible to disassemble nothing to extract a pipe because we play on flexibility. The duct (s) may have bellows.

Ce système de raccord offre l'avantage d'être une solution moins coûteuse en prix pièce et en temps de montage que les solutions actuelles et d'autoriser une grande liberté de mouvement entre les deux parties ou conduits réunis par le raccord. Enfin, la mise en place du raccord nécessite un effort d'emmanchement faible. This connection system offers the advantage of being a less costly solution in terms of part price and assembly time than current solutions and of allowing great freedom of movement between the two parts or conduits joined by the connection. Finally, the fitting of the fitting requires a low fitting force.
