Abstract
Description
La présente invention concerne un volet pour conduit d'air, notamment pour une installation de chauffage et/ou de climatisation, en particulier pour véhicule automobile. The present invention relates to a flap for an air duct, in particular for a heating and / or air conditioning installation, in particular for a motor vehicle.
Habituellement ce volet présente un corps muni de tourillons propre à être disposé dans un conduit de façon à pivoter autour de l'axe des tourillons et à pouvoir obstruer ledit conduit de manière étanche. Usually this flap has a body provided with pins suitable for being arranged in a conduit so as to pivot around the axis of the pins and to be able to obstruct said conduit in a sealed manner.
Pour ce faire, le corps, de forme générale rectangulaire, comporte, sur son pourtour, un joint d'étanchéité qui, lorsque le volet est en position d'obturation, coopère avec les parois du conduit de façon à empêcher tout passage d'air au-delà de ce volet. To do this, the body, of generally rectangular shape, comprises, on its periphery, a seal which, when the shutter is in the closed position, cooperates with the walls of the duct so as to prevent any passage of air. beyond this strand.
Cependant il a été constaté qu'il se produisait, au niveau des tourillons, une fuite d'air non négligeable pouvant nuire au bon fonctionnement de l'ensemble. However, it has been observed that there is a significant leakage of air at the trunnions which could affect the proper functioning of the assembly.
I1 a été proposé de résoudre ce problème, notamment dans la demande de brevet FR-A-2 505 010 publiée le 5 novembre 1982, dans laquelle la paroi du conduit d'air comprend un palier cylindrique propre à recevoir un tourillon. Ce palier est entoure d'une saillie cylindrique tubulaire qui est orientée vers l'intérieur du conduit et coopère à étanchéité avec une lèvre tubulaire en matière élastiquement déformable faisant partie du volet. I1 has been proposed to solve this problem, in particular in patent application FR-A-2 505 010 published on November 5, 1982, in which the wall of the air duct comprises a cylindrical bearing suitable for receiving a pin. This bearing is surrounded by a tubular cylindrical projection which is oriented towards the inside of the duct and cooperates with sealing with a tubular lip of elastically deformable material forming part of the flap.
Ce dispositif présente néanmoins l'inconvénient de générer, lors de la rotation du volet et à l'endroit du tourillon, des forces de frottement assez importantes nécessitant un couple élevé pour manoeuvrer ce volet. Ce couple se répercute sur la commande, actionnée par le conducteur, en nécessitant de sa part un effort assez important sur ladite commande, cet effort pouvant nuire au confort d'utilisation de celle-ci. This device nevertheless has the drawback of generating, during the rotation of the flap and at the location of the journal, fairly large friction forces requiring a high torque to operate this flap. This torque has repercussions on the command, actuated by the driver, requiring on its part a fairly significant effort on said command, this effort being able to harm the comfort of use thereof.
L'invention se donne pour but de remédier à ces inconvénients en procurant un volet grâce auquel l'étanchéité est maximale et le mouvement en rotation de celui-ci est plus aisé tout en réalisant l'étanchéité d'une manière économique. The invention aims to remedy these drawbacks by providing a shutter through which the seal is maximum and the rotational movement thereof is easier while achieving the seal in an economical manner.
Selon l'invention, le volet pour conduit d'air, notamment pour une installation de chauffage et/ou de climatisation en particulier pour véhicule automobile, comportant un corps portant sur son pourtour un joint d'étanchéité et muni d'au moins un tourillon propre à être disposé dans un palier porté par une paroi du conduit d'air de façon à pivoter autour de l'axe du tourillon, un dispositif d'étanchéité étant prévu dans la région dudit tourillon, ledit volet est caractérisé en ce que le dispositif d'étanchéité comprend une lèvre circonférentielle saillante radialement à partir du tourillon en étant surmoulé à partir de celui-ci et propre à être incluse dans le palier. According to the invention, the flap for an air duct, in particular for a heating and / or air conditioning installation, in particular for a motor vehicle, comprising a body bearing on its periphery a seal and provided with at least one pin. suitable for being disposed in a bearing carried by a wall of the air duct so as to pivot around the axis of the journal, a sealing device being provided in the region of said journal, said flap is characterized in that the device The seal comprises a circumferential lip projecting radially from the pin while being overmolded therefrom and suitable for being included in the bearing.
Grâce à cette lèvre, outre l'étanchéité réalisée sur le pourtour du volet, une étanchéité fiable est réalisée au niveau du tourillon tout en rendant la configuration du volet plus simple. Thanks to this lip, in addition to the seal produced on the periphery of the flap, a reliable seal is produced at the pin while making the configuration of the flap simpler.
Selon une autre caractéristique de l'invention, la lèvre va radialement en s'amincissant vers l'extérieur. According to another characteristic of the invention, the lip tapers radially towards the outside.
Cet amincissement procure une plus grande souplesse à la lèvre qui pourra, de ce fait, épouser plus facilement la forme du palier. This thinning provides greater flexibility to the lip which can, therefore, more easily match the shape of the bearing.
Selon une autre caractéristique, la lèvre est surmoulée dans une rainure portée par le tourillon. According to another characteristic, the lip is overmolded in a groove carried by the pin.
Selon une autre caractéristique, le palier comporte une portée cylindrique et un alésage. According to another characteristic, the bearing has a cylindrical bearing surface and a bore.
Selon une autre caractéristique, le diamètre extérieur de la lèvre circonférentielle est au plus égale au diamètre de l'alésage porté par le palier. According to another characteristic, the outside diameter of the circumferential lip is at most equal to the diameter of the bore carried by the bearing.
Selon une autre caractéristique, la lèvre se poursuit axialement par une chicane. According to another characteristic, the lip continues axially by a baffle.
La lèvre circonférentielle ne frottant pas ou peu sur la surface de l'alésage, il en découle une quasi suppression des forces de frottement, mais des fuites au niveau de la lèvre peuvent se produire. Grâce à la chicane formée entre le palier et le tourillon, celles-ci sont pratiquement arrêtées. The circumferential lip does not rub or little on the surface of the bore, it results in a virtual suppression of the friction forces, but leaks at the level of the lip can occur. Thanks to the baffle formed between the bearing and the trunnion, these are practically stopped.
Les autres caractéristiques et avantages de l'invention ressortiront de ;La description qui va suivre en se référant aux dessins annexés sur lesquels
- la figure 1 est une vue partielle du volet montrant le dispositif d'étanchéité selon l'invention
- la figure 2 est une vue partielle montrant le volet avec le dispositif d'étanchéité placé dans un palier d'un conduit d'air.The other characteristics and advantages of the invention will become apparent from; The description which follows with reference to the appended drawings in which
- Figure 1 is a partial view of the flap showing the sealing device according to the invention
- Figure 2 is a partial view showing the shutter with the sealing device placed in a bearing of an air duct.
Sur la figure 1, le volet 1 comprend un corps. de volet 2 muni d'au moins un tourillon 3 généralement cylindrique. Le corps de volet 2 de forme générale rectangulaire comporte, sur son pourtour, un joint d'étanchéité 4, qui peut être surmoulé avec ledit corps. In Figure 1, the flap 1 comprises a body. flap 2 provided with at least one generally cylindrical pin 3. The shutter body 2 of generally rectangular shape has, on its periphery, a seal 4, which can be molded with said body.
Le tourillon 3 porte au voisinage de son extrémité externe une denture 5 servant à la commande en rotation du volet 1. Cette denture se prolonge en direction du corps du volet par une partie cylindrique lisse 6, ici appelée pivot, de plus grand diamètre que le diamètre des dentures 5. Le pivot 6 est limité axialement par un épaulement 7 constitué par une partie cylindrique 8 de plus grand diamètre et qui se prolonge axialement par une diminution de diamètre 9, laquelle se prolonge par une rainure 10 de diamètre inférieur se situant à proximité du joint d'étanchéité 4 et limité axialement par un rebord Il. The pin 3 carries in the vicinity of its outer end a toothing 5 for controlling the rotation of the flap 1. This toothing is extended towards the body of the flap by a smooth cylindrical part 6, here called a pivot, of larger diameter than the diameter of the teeth 5. The pivot 6 is axially limited by a shoulder 7 constituted by a cylindrical part 8 of larger diameter and which is extended axially by a reduction in diameter 9, which is extended by a groove 10 of smaller diameter lying at proximity to the seal 4 and axially limited by a flange II.
C'est dans cette rainure 10 qu'est surmoulée la lèvre 12, constituant le dispositif d'étanchéité. It is in this groove 10 that the lip 12 is molded, constituting the sealing device.
Comme mieux visible sur la figure, la lèvre 12 s'étend circonférentiellement et s'érige radialement vers l'extérieur à partir du fond de la rainure 10 en étant de plus grand diamètre que la partie cylindrique 8. De préférence, cette lèvre a, en section, une forme qui va en s'amincissant de sa base vers l'extérieur. Cet amincissement procure une configuration sensiblement triangulaire dont le sommet du triangle est arrondie. As best seen in the figure, the lip 12 extends circumferentially and rises radially outwards from the bottom of the groove 10, being of larger diameter than the cylindrical part 8. Preferably, this lip has, in section, a shape that tapers from its base outwards. This thinning provides a substantially triangular configuration, the apex of the triangle is rounded.
En outre, il peut être envisagé que la lèvre 12 et le joint 4 soient surmoulés lors de la même opération. Ceci est possible lors du surmoulage en permettant au film de matière élastiquement déformable de cheminer du joint 4 à la lèvre 12 par une partie du moule laissé libre. Ainsi cette facilité d'exécution se concrétise par la création d'une mince couche 13 de matière élastiquement déformable. In addition, it can be envisaged that the lip 12 and the seal 4 are overmolded during the same operation. This is possible during overmolding by allowing the film of elastically deformable material to travel from the seal 4 to the lip 12 through a part of the mold left free. Thus, this ease of execution takes the form of the creation of a thin layer 13 of elastically deformable material.
Sur la figure 2, le volet 1 avec le dispositif d'étanchéité 12 est rapporté dans un conduit d'air 14, par exemple un canal d'air d'une installation de chauffage etou de climatisation, notamment pour véhicule automobile. In FIG. 2, the shutter 1 with the sealing device 12 is attached in an air duct 14, for example an air channel of a heating and air conditioning installation, in particular for a motor vehicle.
Le conduit 14 présente une paroi 15 munie d'un palier 16 apte à recevoir un tourillon 3 et saillant sensiblement perpendiculairement hors de la paroi 15 et comportant, à partir de l'extrémité saillante, une portée interne cylindrique 17 limitée par un épaulement 18 issu de l'alésage interne 19 débouchant à travers la paroi 15 et de plus grand diamètre que le diamètre de la portée 17. The conduit 14 has a wall 15 provided with a bearing 16 capable of receiving a pin 3 and projecting substantially perpendicularly from the wall 15 and comprising, from the projecting end, a cylindrical internal bearing 17 limited by a shoulder 18 from of the internal bore 19 opening through the wall 15 and of larger diameter than the diameter of the bearing surface 17.
Ainsi, comme mieux visible sur la figure, le tourillon 3 est rapporté dans le palier 16 de manière à ce que le pivot 6 soit supporté par la portée 17, que l'épaulement 7 limitant ledit pivot vienne en contact avec l'épaulement 18 limitant ladite portée, et que la lèvre 12 d'étanchéité soit incluse dans l'alésage 18. Thus, as best seen in the figure, the pin 3 is attached in the bearing 16 so that the pivot 6 is supported by the bearing 17, that the shoulder 7 limiting said pivot comes into contact with the shoulder 18 limiting said bearing surface, and that the sealing lip 12 is included in the bore 18.
Ainsi, l'extrémité de la lèvre 12 s'appuyant sur l'alésage interne 19, empêche les fuites d'air et cela quelle que soit la position du volet. Thus, the end of the lip 12 resting on the internal bore 19, prevents air leaks, regardless of the position of the flap.
De préférence, il est souhaitable que le diamètre externe de la lèvre 12 soit au plus égale au diamètre de l'alésage 19, de façon à supprimer les forces de frottement entre ces deux parties. Dans ce cas, il est prévu une chicane 20 au-delà de la lèvre 12 et qui est constituée par un volume 21 limité par la paroi interne de l'alésage 19 et la diminution de diamètre 9 et par les épaulements 7 et 18. Preferably, it is desirable for the external diameter of the lip 12 to be at most equal to the diameter of the bore 19, so as to eliminate the friction forces between these two parts. In this case, a baffle 20 is provided beyond the lip 12 and which is constituted by a volume 21 limited by the internal wall of the bore 19 and the reduction in diameter 9 and by the shoulders 7 and 18.
Grâce à cette disposition, les fuites d'air passant entre l'extrémité de la lèvre 12 et la paroi de l'alésage 19 se trouvent perturbées une première fois dans le volume 21 et sont de nouveau perturbées entre l'épaulement 7 limitant le pivot et l'épaulement 18 limitant la portée 17. En pratique, grâce à cette chicane, les fuites d'air sont considérées comme négligeables. Thanks to this arrangement, the air leaks passing between the end of the lip 12 and the wall of the bore 19 are disturbed for the first time in the volume 21 and are again disturbed between the shoulder 7 limiting the pivot. and the shoulder 18 limiting the range 17. In practice, thanks to this baffle, air leaks are considered to be negligible.
La présente invention n'est pas limitée à l'exemple de réalisation décrit ci-dessus, mais englobe toutes variantes. Notamment la forme, en section, de la lèvre 12 peut être quelconque, comme par exemple cylindrique, tout en étant surmoulée. The present invention is not limited to the embodiment described above, but encompasses all variants. In particular, the shape, in section, of the lip 12 can be arbitrary, such as for example cylindrical, while being overmolded.
