Description
Distributeur de fluide, du type à boisseau tournant. Fluid distributor, of the rotating plug type.
La présente invention a pour objet un distributeur de fluide qui peut être utilisé notamment dans les dispositifs de climatisa tion des véhicules automobiles. The present invention relates to a fluid distributor which can be used in particular in air conditioning devices of motor vehicles.
Ce distributeur comprend un corps ou carter cylindrique qui est muni à sa périphérie d'une série d'ouvertures d'admission et de distribution, et un boisseau qui est monté pivotant dans ce corps, et est caractérisé en ce que le boisseau comporte deux aubes à génératrices parallèles, qui sont reliées à des flasques d'extrémité, la première étant une aube obturatrice appliquée contre la paroi intérieure du corps et pouvant obturer l'une quelconque des ouvertures d'admission et de distribution, selon la position angulaire du boisseau, alors que l'autre est une aube déflectrice disposée en retrait par rapport à la première aube, en délimitant avec celle-ci ou avec la paroi du corps un passage propre à mettre en communication deux ouvertures lune avec l'autre. This distributor comprises a cylindrical body or casing which is provided at its periphery with a series of intake and distribution openings, and a plug which is pivotally mounted in this body, and is characterized in that the plug has two blades with parallel generators, which are connected to end flanges, the first being a shutter vane applied against the inner wall of the body and capable of closing any of the intake and distribution openings, depending on the angular position of the plug, while the other is a deflecting vane arranged in withdrawal with respect to the first vane, delimiting with the latter or with the wall of the body a passage suitable for bringing two moon openings into communication with the other.
On a décrit ci-après, à titre d'exemple non limitatif, un mode de réalisation du distributeur selon l'invention avec référence au dessin annexe dans lequel
La Figure 1 est une vue en perspective du distributeur,
La Figure 2 est une vue en perspective du boisseau,
Les Figures 3 à 7 sont des vues en coupe transversale du distributeur, dans diverses positions du boisseau,
La Figure 8 montre une variante du distributeur en coupe transversale.An embodiment of the dispenser according to the invention has been described below, by way of non-limiting example, with reference to the accompanying drawing in which
FIG. 1 is a perspective view of the dispenser,
FIG. 2 is a perspective view of the plug,
Figures 3 to 7 are cross-sectional views of the distributor, in various positions of the plug,
Figure 8 shows a variant of the distributor in cross section.
Tel qu'il est représenté au dessin, le distributeur rotatif selon l'invention comprend essentiellement un carter 1 et un boisseau tournant 2. As shown in the drawing, the rotary distributor according to the invention essentially comprises a casing 1 and a rotary plug 2.
Le carter 1 a la forme d'un cylindre d'axe horizontal, qui est fermé sur ses deux faces latérales. La paroi de ce carter comporte un certain nombre d'ouvertures dont chacune est entourée par une buse extérieure permettant son raccordement à un conduit. D'une manière plus précise, le carter comporte une buse frontale d'admission 3 d'axe horizontal, qui est reliée à une source d'air pulsé, une buse supérieure de distribution 4, d'axe vertical, deux buses inférieures de distribution 5 et 5', également d'axe vertical, et une buse arrière de distribution 6 dont l'axe est oblique et situé au-dessus du plan horizontal.Les ouvertures de ces buses s'étendent sur un angle d'environ 65 à 700; les arêtes A (ot se rencontrent le bord de gauche de la buse 5 ou 5' et le bord inférieur de la buse 3),
B (où se rencontrent le bord supérieur de la buse 3 et le bord de gauche de la buse 4), C (où se rencontrent le bord de droite de la buse 4 et le bord supérieur de la buse 6), D (bord inférieur de la buse 6), et E (bord de droite de la buse 5 ou 5') sont réparties de manière sensiblement régulière autour de l'axe du carter 1, c'està-dire qu'elles se trouvent sensiblement à 70 à 750 les unes des autres. Le carter comporte, en outre, deux buses latérales de distribution 7 qui sont excentrées et placées à proximité de la buse d'admission 3, chacune sur l'une des faces latérales du carter.The casing 1 has the shape of a cylinder with a horizontal axis, which is closed on its two lateral faces. The wall of this casing has a number of openings, each of which is surrounded by an external nozzle allowing its connection to a conduit. More precisely, the casing comprises a front inlet nozzle 3 with a horizontal axis, which is connected to a source of forced air, an upper distribution nozzle 4, with a vertical axis, two lower distribution nozzles 5 and 5 ', also with a vertical axis, and a rear distribution nozzle 6 whose axis is oblique and situated above the horizontal plane. The openings of these nozzles extend over an angle of approximately 65 to 700 ; the edges A (ot meet the left edge of the nozzle 5 or 5 ′ and the lower edge of the nozzle 3),
B (where the upper edge of nozzle 3 and the left edge of nozzle 4 meet), C (where the right edge of nozzle 4 and upper edge of nozzle 6 meet), D (lower edge of nozzle 6), and E (right edge of nozzle 5 or 5 ') are distributed in a substantially regular manner around the axis of housing 1, that is to say that they are substantially at 70 to 750 each other. The casing further comprises two lateral distribution nozzles 7 which are eccentric and placed near the intake nozzle 3, each on one of the lateral faces of the casing.
Le boisseau 2 est formé de deux flasques circulaires 8 et 8' dont le diamètre est légèrement inférieur à celui du carter 1 et qui sont réunis l'un à l'autre par une aube obturatrice 9 et une aube déflectrice 10 de longueur légèrement inférieure à celle de ce carter. Chacun des flasques possède un tourillon 11 ou 11, qui est engagé dans un trou prévu au centre de la face latérale correspondante du carter; l'un de ces tourillons est solidaire d'un organe de manoeuvre non représenté et permettant de faire tourner le boisseau dans le carter. The plug 2 is formed by two circular flanges 8 and 8 ′ whose diameter is slightly less than that of the casing 1 and which are joined to each other by a shutter blade 9 and a deflecting blade 10 of length slightly less than that of this housing. Each of the flanges has a pin 11 or 11, which is engaged in a hole provided in the center of the corresponding lateral face of the casing; one of these pins is integral with an operating member (not shown) and which makes it possible to rotate the plug in the casing.
L'aube obturatrice 9 a une section en arc de cercle et est reliée à la périphérie de chacun des flasques 8 et 8'; son rayon est égal à celui des flasques de sorte qu'elle se trouve au contact de la paroi interne du carter 1. Elle s'étend sur un angle suffisamment grand, de l'ordre de 750, pour obturer l'ouverture d'une buse lorsqulelle est placée en regard de celle-ci. The shutter vane 9 has a circular arc section and is connected to the periphery of each of the flanges 8 and 8 '; its radius is equal to that of the flanges so that it is in contact with the internal wall of the casing 1. It extends over a sufficiently large angle, of the order of 750, to close the opening of a nozzle when it is placed opposite it.
L'aube déflectrice 10 est disposée à l'intérieur du boisseau et est galbée, sa convexité étant dirigée vers l'aube 9; dans l'exemple représenté, cette aube a une section en arc de cercle, son rayon étant un peu supérieur à celui de l'aube 9, et son plan de symétrie est confondu avec celui de cette aube 9. Elle s'étend jusqu'à la périphérie des flasques 8 et 8', les points de contact de ses bords longitudinaux avec les flasques ayant un écart angulaire de l'ordre de 140 à 1500 et approximativement égal à celui séparant le bord supérieur de l'ouverture de la buse 6 du bord in férieur de l'ouverture de la buse 3 (voir Fig. 6). The deflecting vane 10 is disposed inside the plug and is curved, its convexity being directed towards the vane 9; in the example shown, this blade has a circular arc section, its radius being a little greater than that of blade 9, and its plane of symmetry is coincident with that of this blade 9. It extends up to at the periphery of the flanges 8 and 8 ', the points of contact of its longitudinal edges with the flanges having an angular difference of the order of 140 to 1500 and approximately equal to that separating the upper edge of the opening of the nozzle 6 from the lower edge of the nozzle opening 3 (see Fig. 6).
Les deux flasques 8 et 8' comportent chacun une échancrure 12 sensiblement symétrique par rapport à un plan diamétral approximativement perpendiculaire au plan de symétrie des aubes 9 et 10. The two flanges 8 and 8 ′ each have a notch 12 which is substantially symmetrical with respect to a diametral plane approximately perpendicular to the plane of symmetry of the blades 9 and 10.
Elle sUtend sur un angle d'environ 100 à 1200.It extends over an angle of approximately 100 to 1,200.
A la Figure 3, l'aube 9 est disposée en regard de l'ouverture de la buse d'arrivée 3 qu'elle obture. L'aube 10 fait face à la buse 6 et forme écran en empêchant le passage vers cette buse de l'air pouvant éventuellement provenir des autres buses. In Figure 3, the blade 9 is arranged opposite the opening of the inlet nozzle 3 which it closes. The blade 10 faces the nozzle 6 and forms a screen by preventing the passage towards this nozzle of the air which may possibly come from the other nozzles.
A la Figure 4, le boisseau 2 a pivoté et l'aube 9 se trouve en regard de l'ouverture de la buse 4; l'aube 10 s'étend sensiblement depuis le bord inférieur de la buse 6 jusqu'au bord de gauche de la buse 5 ou 5'. L'espace curviligne 13 existant entre les aubes 9 et 10 relie les buses 3 et 6 de sorte que l'air parvenant à la buse 3 s'échappe par la buse 6. In Figure 4, the plug 2 has pivoted and the blade 9 is located opposite the opening of the nozzle 4; the blade 10 extends substantially from the lower edge of the nozzle 6 to the left edge of the nozzle 5 or 5 '. The curvilinear space 13 existing between the vanes 9 and 10 connects the nozzles 3 and 6 so that the air reaching the nozzle 3 escapes through the nozzle 6.
A la Figure 5, le boisseau 2 a pivoté davantage de façon que l'aube 9 se trouve en regard de l'ouverture de la buse 6. L'aube 10 s'étend sensiblement depuis le bord supérieur de la buse 3 jusqu'au bord de droite de la buse 5 ou 5' et met en communication la buse 3 et les buses 5 et 5'. In Figure 5, the plug 2 has pivoted further so that the blade 9 is opposite the opening of the nozzle 6. The blade 10 extends substantially from the upper edge of the nozzle 3 to right edge of nozzle 5 or 5 'and connects nozzle 3 and nozzles 5 and 5'.
A la Figure 6, l'aube 9 est appliquée contre la paroi du carter entre les buses 5-5' et 6, -l'aube 10 s'étend sensiblement depuis le bord inférieur de la buse 3 jusqu'au bord de droite de la buse 4 et met en communication ces buses 3 et 4. Par ailleurs, l'air provenant de la buse 3 passe également dans les buses latérales 7 à travers les échancrures 11 des flasques. In FIG. 6, the blade 9 is applied against the wall of the casing between the nozzles 5-5 ′ and 6, the blade 10 extends substantially from the lower edge of the nozzle 3 to the right edge of the nozzle 4 and puts these nozzles 3 and 4 into communication. Furthermore, the air coming from the nozzle 3 also passes into the side nozzles 7 through the notches 11 of the flanges.
Enfin, dans la position de la Figure 7, l'aube 9 obture les ouvertures des buses 5 et 5'; l'aube 10 s'étend sensiblement depuis le bord de gauche de la buse 4 jusqu'au bord inférieur de la buse 6 et forme écran en empêchant l'air de passer dans ces buses 4 et 6. Finally, in the position of Figure 7, the blade 9 closes the openings of the nozzles 5 and 5 '; the blade 10 extends substantially from the left edge of the nozzle 4 to the lower edge of the nozzle 6 and forms a screen by preventing air from passing through these nozzles 4 and 6.
L'air peut passer cependant dans les buses 7 par les échancrures 11.Air can, however, pass through the nozzles 7 through the notches 11.
Ce distributeur convient notamment pour assurer une répartition d'air pulsé à l'intérieur d'un habitacle de véhicule automobile équipé d'un système climatiseur. Dans ce cas, les buses 6 et 5 sont reliées respectivement à la partie supérieure de l'habitacle et à la partie inférieure de celui-ci; la buse 4 est reliée à un circuit de désembuage ou de dégivrage du pare-brise et éventuel- lement à la lunette arrière; les buses 7 sont reliées à un circuit de désembuage ou de dégivrage des vitres latérales. This distributor is particularly suitable for ensuring a distribution of forced air inside a passenger compartment of a motor vehicle equipped with an air conditioning system. In this case, the nozzles 6 and 5 are respectively connected to the upper part of the passenger compartment and to the lower part thereof; the nozzle 4 is connected to a demisting or defrosting circuit of the windshield and possibly to the rear window; the nozzles 7 are connected to a defogging or defrosting circuit of the side windows.
Le distributeur permet alors d'assurer, dans la position de la Figure 4, l'aération ou le chauffage de la zone supérieure i lhabitacle, - dans la position de la Figure 5, l'aération ou le chauffage de la zone inférieure de l'habitacle, - dans la position de la Figure 6, un désembuage ou un dégivrage général des surfaces vitrées; - dans la position de la Figure 7, un désembuage ou un dégivrage particulier des glaces latérales. The distributor then makes it possible to ensure, in the position of Figure 4, ventilation or heating of the upper zone i the passenger compartment, - in the position of Figure 5, ventilation or heating of the lower zone of the cabin, - in the position of Figure 6, demisting or general defrosting of the glass surfaces; - in the position of Figure 7, a specific demisting or defrosting of the side windows.
Comme le montre la Figure 8, on peut prévoir un volet de réglage 14 sur la buse d'admission 3. I1 est ainsi possible de régler le débit d'air, voire d'arrêter l'alimentation en air sans modifier la position du boisseau 2. As shown in Figure 8, an adjustment flap 14 can be provided on the intake nozzle 3. It is thus possible to adjust the air flow, or even to stop the air supply without changing the position of the plug. 2.
I1 va de soi que la présente invention ne doit pas être considérée comme limitée au mode de réalisation décrit et repré senté, mais en couvre, au contraire, toutes les variantes. It goes without saying that the present invention should not be considered as limited to the embodiment described and shown, but on the contrary covers all variants thereof.
