Sur les figures 3A à 3C on a représenté un connecteur fluidique 10 pour 30 véhicule automobile du type boîtier papillon ou bypass. FIGS. 3A to 3C show a fluidic connector 10 for a motor vehicle of the throttle or bypass housing type.
Un tel connecteur fluidique 10 peut avantageusement être utilisé dans la ligne d'échappement du moteur pour gérer le flux des gaz d'échappement et rediriger une partie de ces gaz d'échappement vers le moteur pour le dépolluer. Such a fluidic connector 10 may advantageously be used in the exhaust line of the engine to manage the flow of exhaust gas and redirect a portion of this exhaust gas to the engine to clean up.
Ce connecteur fluidique 10 comporte une entrée et deux sorties de fluide ainsi qu'un sélecteur adapté à mettre en communication de manière sélective ladite entrée avec l'une ou l'autre des deux sorties. This fluid connector 10 comprises an inlet and two fluid outlets and a selector adapted to selectively put in communication said input with one or the other of the two outputs.
Selon l'exemple représenté sur les figures, le connecteur fluidique 10 comporte un corps 140 à l'intérieur duquel est définie une chambre de circulation de fluide 141. Ce corps 140 présente ici la forme d'un entonnoir avec une entrée circulaire 142 de petit diamètre et une sortie circulaire 143 de plus grand diamètre. According to the example shown in the figures, the fluidic connector 10 comprises a body 140 inside which is defined a fluid circulation chamber 141. This body 140 here has the shape of a funnel with a circular inlet 142 of small diameter and a circular output 143 of larger diameter.
Le sélecteur est monté dans la chambre de circulation de fluide 141 de manière à séparer la sortie circulaire 143 du corps 140 en deux sorties, ici de section identique, du connecteur fluidique 140. The selector is mounted in the fluid circulation chamber 141 so as to separate the circular output 143 of the body 140 into two outputs, here of identical section, of the fluid connector 140.
Les sorties 143 du connecteur fluidique 140 peuvent être raccordées à un échangeur alors que l'entrée 142 peut être raccordée à une arrivée de gaz d'échappement. The outputs 143 of the fluid connector 140 may be connected to an exchanger while the inlet 142 may be connected to an exhaust gas supply.
Comme le montrent plus particulièrement les figures 1 et 2, le sélecteur comprend un volet 110 solidarisé à un arbre 120 d'entraînement en rotation du volet 110. As shown more particularly in Figures 1 and 2, the selector comprises a flap 110 secured to a shaft 120 for rotating the flap 110.
Avantageusement, selon l'invention, le volet 110 et l'arbre 120 sont solidarisés l'un à l'autre par un moyen d'emboîtement mécanique démontable. Advantageously, according to the invention, the flap 110 and the shaft 120 are secured to one another by a removable mechanical interlocking means.
Ici, le volet 110 est une pièce monobloc qui comporte à l'avant un battant 113 et à l'arrière un tube d'assemblage 111. L'arbre 110 est préférentiellement une pièce monobloc, réalisée en acier Inox fritté, qui comporte une tige 121 sur laquelle est enfilé le tube d'assemblage 111 du volet 110. Here, the flap 110 is a one-piece piece which comprises at the front a leaf 113 and at the rear an assembly tube 111. The shaft 110 is preferably a one-piece piece, made of sintered stainless steel, which comprises a rod 121 on which is threaded the assembly tube 111 of the flap 110.
L'assemblage du volet 110 et l'arbre 120 est plus généralement réalisé par coopération de formes. A cet effet, ledit moyen d'assemblage du volet 110 et de l'arbre 120 comprend sur l'une ou l'autre des pièces constituées par le tube d'assemblage 111 du volet 110 et l'arbre 120, une empreinte femelle 112 destinée à recevoir une empreinte mâle 122A prévue sur l'autre pièce. The assembly of the flap 110 and the shaft 120 is more generally achieved by cooperation of forms. For this purpose, said assembly means of the flap 110 and the shaft 120 comprises on one or the other of the pieces constituted by the assembly tube 111 of the flap 110 and the shaft 120, a female fingerprint 112. intended to receive a male 122A provided on the other piece.
Plus particulièrement, l'arbre 120 comporte à une extrémité de sa tige 121 une tête de commande 122 pourvue à sa base de ladite empreinte mâle, constituée ici par deux pattes rectangulaires 122A disposées de part et d'autre de l'axe de la tige 121, et le tube d'assemblage 111 du volet 110 comporte en correspondance à son embouchure deux encoches 112 rectangulaires, destinées à recevoir lesdites pattes rectangulaires 122A. More particularly, the shaft 120 comprises at one end of its rod 121 a control head 122 provided at its base with said male cavity, here constituted by two rectangular tabs 122A disposed on either side of the axis of the rod 121, and the assembly tube 111 of the flap 110 comprises in correspondence with its mouth two rectangular notches 112 for receiving said rectangular tabs 122A.
La tige 121 de l'arbre 120 traverse le tube d'assemblage 111 du volet 110 de manière que l'extrémité de la tige 121 opposée à la tête de commande 122 émerge dudit tube d'assemblage 111 (voir figure 2). La tête de commande 122 de l'arbre 120 émerge également du tube d'assemblage 111 du volet 110, seul son empreinte mâle 122A est emboîtée dans l'empreinte femelle 112 correspondante du volet 110 pour le lier en rotation à l'arbre 120. The shaft 121 of the shaft 120 passes through the assembly tube 111 of the flap 110 so that the end of the rod 121 opposite the control head 122 emerges from said assembly tube 111 (see Figure 2). The control head 122 of the shaft 120 also emerges from the assembly tube 111 of the flap 110, only its male cavity 122A is nested in the corresponding female cavity 112 of the flap 110 in order to link it in rotation with the shaft 120.
Le volet 110 solidarisé à l'arbre 120 est monté dans le corps 140 du connecteur fluidique 10 de manière que, d'une part, le tube d'assemblage 111 du volet 110 s'étend dans la sortie circulaire 143 du corps 140 pour la séparer en deux sorties du connecteur, et que, d'autre part, l'extrémité libre de la tige 121 ainsi que la base de la tête de commande 122 de l'arbre 1 traverse librement ledit corps 140. Le battant 113 du volet 110 s'étend à partir de la sortie circulaire 143 vers l'entrée circulaire 142 du corps 140 au travers de la chambre de circulation de fluide 141 (voir figures 4A et 4B). L'extrémité libre de la tige 121 de l'arbre 120 qui émerge du volet 110 est montée à rotation libre dans un logement situé sous la sortie circulaire 143 du corps 140. The shutter 110 secured to the shaft 120 is mounted in the body 140 of the fluid connector 10 so that, on the one hand, the assembly tube 111 of the flap 110 extends into the circular outlet 143 of the body 140 for the separating into two outputs of the connector, and that, on the other hand, the free end of the rod 121 and the base of the control head 122 of the shaft 1 passes freely through said body 140. The flap 113 of the flap 110 extends from the circular exit 143 to the circular inlet 142 of the body 140 through the fluid circulation chamber 141 (see FIGS. 4A and 4B). The free end of the shaft 121 of the shaft 120 which emerges from the flap 110 is mounted to rotate freely in a housing located under the circular outlet 143 of the body 140.
Comme le montrent plus particulièrement les figures 4A et 4B, le corps 140 comprend dans sa paroi interne deux épaulements 145 positionnés en vis-à-vis, de part et d'autre de l'axe X de la chambre de circulation de fluide 141. As shown more particularly in Figures 4A and 4B, the body 140 comprises in its inner wall two shoulders 145 positioned vis-a-vis, on either side of the axis X of the fluid circulation chamber 141.
L'extrémité libre 113A du battant 113 du volet 110 est destinée à venir en appui contre ces épaulements 145 pour limiter la course de pivotement dudit volet 110. The free end 113A of the flap 113 of the flap 110 is intended to bear against these shoulders 145 to limit the pivoting stroke of said flap 110.
Dans le cas typique représenté, l'angle de débattement du volet 110 est de l'ordre de 40 degrés. In the typical case shown, the deflection angle of the flap 110 is of the order of 40 degrees.
L'appui de l'extrémité libre 113A du battant 113 du volet 110 contre chacun desdits épaulement 145 du corps 140 est réalisé de manière étanche. The support of the free end 113A of the flap 113 of the flap 110 against each of said shoulder 145 of the body 140 is made sealingly.
Ainsi, dans une position extrême d'appui du volet 110 contre le corps 140 du connecteur fluidique, l'entrée 142 de celui-ci est mise en communication avec la sortie située à gauche du tube d'assemblage 111 du volet 110 et le fluide circule selon la flèche 1 à gauche du volet (voir figure 4A), et dans l'autre position extrême d'appui du volet 110 contre le corps 140 du connecteur fluidique, l'entrée 142 de celui-ci est mise en communication avec la sortie située à droite du tube d'assemblage 111 du volet 110 et le fluide circule selon la flèche 1 à droite du volet 110 (voir figure 4B). Thus, in an extreme position of support of the flap 110 against the body 140 of the fluidic connector, the inlet 142 thereof is placed in communication with the outlet located to the left of the assembly tube 111 of the flap 110 and the fluid circulates according to the arrow 1 to the left of the flap (see Figure 4A), and in the other extreme position of support of the flap 110 against the body 140 of the fluidic connector, the inlet 142 thereof is placed in communication with the outlet located to the right of the assembly tube 111 of the flap 110 and the fluid flows along the arrow 1 to the right of the flap 110 (see Figure 4B).
Comme le montrent les figures 3A à 3C, le connecteur fluidique 10 comporte un capot de protection 150 qui est fixé au corps 140 au moyen de vis 151. Ce capot de protection comporte une partie 152 qui recouvre la tête de commande 122 de l'arbre 120 émergeant du corps 140 afin de bloquer l'arbre 120 en translation axiale. Cette partie 152 du capot de protection 150 forme alors une butée qui prend appui contre l'extrémité correspondante de l'arbre 120 pour éviter que celui-ci ne se déplace en translation axiale par rapport au corps 140 qu'il traverse librement. As shown in FIGS. 3A to 3C, the fluid connector 10 comprises a protective cover 150 which is fixed to the body 140 by means of screws 151. This protective cover includes a part 152 which covers the control head 122 of the shaft 120 emerging from the body 140 to block the shaft 120 in axial translation. This portion 152 of the protective cover 150 then forms a stop that bears against the corresponding end of the shaft 120 to prevent it from moving in axial translation relative to the body 140 that passes freely.
Le connecteur fluidique 10 comprend un actionneur 130, ici un actionneur pneumatique, raccordé par un système de renvoi à la tête de commande 122 de l'arbre 120 recouverte par ledit capot de protection 150 pour entraîner à rotation ledit arbre 120 autour de son axe. The fluid connector 10 comprises an actuator 130, here a pneumatic actuator, connected by a return system to the control head 122 of the shaft 120 covered by said protective cover 150 to rotate said shaft 120 about its axis.
Selon l'exemple représenté, le système de renvoi est un système de bielle-manivelle qui comporte une bielle 132 sortant de l'actionneur 130 pourvue d'une tête 133 engagée sur un téton 123A porté par un levier 123 fixe issu de la tête de commande 122 de l'arbre 120 (voir figures 1 et 2). According to the example shown, the return system is a rod-crank system which comprises a rod 132 coming out of the actuator 130 provided with a head 133 engaged on a pin 123A carried by a fixed lever 123 from the head of control 122 of the shaft 120 (see Figures 1 and 2).
Bien entendu selon une variante non représentée on pourra prévoir que le système de renvoi est un système à pignons d'engrenage. Of course according to a variant not shown, it can be provided that the return system is a gear pinion system.
Le capot de protection 150 recouvre et protège le système de renvoi, il permet également de supporter l'actionneur 130. À cet effet, le capot de protection comporte des pattes 153 en pétale qui sont soudées au corps de l'actionneur 130. The protective cover 150 covers and protects the return system, it also supports the actuator 130. For this purpose, the protective cover includes tabs 153 petal which are welded to the body of the actuator 130.
Le connecteur fluidique 10 représenté sur les figures présente les avantages suivants: - il est simple et économique à réaliser du fait de l'assemblage démontable du volet et de l'arbre; - l'assemblage par emboîtement ou par coopération de formes de l'arbre avec le volet permet d'assurer non seulement la solidarisation en rotation de l'arbre avec ledit volet mais aussi le centrage l'arbre par rapport au volet; l'arbre qui traverse librement le corps n'est pas emmanché à force dans celui-ci et peut donc être centré facilement par rapport audit corps; - le capot de protection sert non seulement à protéger le mécanisme de rotation de l'arbre mais aussi à bloquer en translation ledit arbre qui n'est pas emmanché à force dans le corps et à supporter l'actionneur. L'ensemble est donc économique et fiable. The fluidic connector 10 shown in the figures has the following advantages: it is simple and economical to produce because of the dismountable assembly of the shutter and the shaft; the assembly by interlocking or by cooperation of shapes of the shaft with the flap makes it possible not only to secure the shaft with said flap in rotation but also to center the shaft with respect to the flap; the shaft which passes freely through the body is not forced into it and can therefore be easily centered with respect to said body; - The protective cover serves not only to protect the rotation mechanism of the shaft but also to lock in translation said shaft which is not forced into the body and to support the actuator. The whole is therefore economical and reliable.
La présente invention n'est nullement limitée au mode de réalisation décrit et représenté mais l'homme du métier saura y apporter toute variante conforme à son esprit. The present invention is not limited to the embodiment described and shown but the skilled person will be able to make any variant within his mind.
