En se reportant à la figure 1, une buse de distribution, selon l'invention, est constituée d'un noyau de centrage 3 de forme générale cylindrique, monté sans jeu transversal à l'intérieur d'un alésage 10 porté par un support 1, par exemple un bouton-poussoir équipé de ladite buse; l'alésage 10 est l'alésage intérieur d'un manchon 2 solidarisé au bouton-poussoir 1 dans un alésage 13 de celui-ci ouvert à l'extérieur; le noyau de centrage 3, le manchon 2 et l'alésage 13, tous trois de révolution, ori C-u axe commun 20 Le manchon 2 comporte, à son extrémité voisine de l'extérieur, un fond, dont la face intérieure 11 est de forme conique, percé d'un orifice de sortie 6 selon l'axe 20, ledit orifice 6 étant constitué d'un ajutage cylindrique débouchant à l'extérieur suivant une partie de forme conique divergente ; en regard de la face intérieure de forme conique 11 du fond du manchon 2, l'extrémité du noyau de centrage 3 a une partie tronconique, désignée par le repère 12 sur la figure, raccordée à une Referring to Figure 1, a dispensing nozzle, according to the invention, consists of a centering core 3 of generally cylindrical shape, mounted without transverse play inside a bore 10 carried by a support 1 , for example a push button fitted with said nozzle; the bore 10 is the internal bore of a sleeve 2 secured to the push button 1 in a bore 13 thereof open to the outside; the centering core 3, the sleeve 2 and the bore 13, all three of revolution, ori Cu common axis 20 The sleeve 2 has, at its end close to the outside, a bottom, the inner face 11 of which is shaped conical, pierced with an outlet orifice 6 along the axis 20, said orifice 6 consisting of a cylindrical nozzle opening to the outside in a part of divergent conical shape; opposite the conical interior face 11 of the bottom of the sleeve 2, the end of the centering core 3 has a frustoconical part, designated by the reference 12 in the figure, connected to a
face plane perpendiculaire à l'axe 20 et située à distance de l'orifice 6. flat face perpendicular to the axis 20 and located at a distance from the orifice 6.
A l'interface entre le noyau 3 et l'alésage 10, plus précisément sur la face extérieure cylindrique 9 du noyau 3, est creusé un canal de distribution 4 s'étendant de manière hélicoïdale: on a désigné par 4 a la première spire, de l'hélice qui constitue le canal 4, en At the interface between the core 3 and the bore 10, more precisely on the cylindrical outer face 9 of the core 3, is hollowed out a distribution channel 4 extending helically: the first turn is designated by 4, of the propeller which constitutes channel 4, in
se référant au sens de l'écoulement du fluide, comme on le verra ci- referring to the direction of fluid flow, as will be seen below
après, et par 4 N la dernière spire; la spire 4 _ se termine au droit de la partie tronconique 12 de l'extrémité du noyau 3; la première spire 4 a prend naissance à l'extrémité opposée du noyau 3 (par rapport à l'extrémité dudit noyau 3 qui fait face à l'orifice 6) qui s'étend à l'extérieur de l'alésage 10 du manchon 2, de sorte qu'une chambre annulaire 8, d'axe 20, est définie par le noyau 3, le manchon 2 et le after, and by 4 N the last turn; the coil 4 _ ends at the right of the frustoconical part 12 of the end of the core 3; the first turn 4a originates at the opposite end of the core 3 (relative to the end of said core 3 which faces the orifice 6) which extends outside the bore 10 of the sleeve 2 , so that an annular chamber 8, of axis 20, is defined by the core 3, the sleeve 2 and the
support 1; la spire 4 a communique avec l'intérieur de la chambre 8. support 1; the coil 4 has communication with the interior of the chamber 8.
Le support 1 porte, comme cela est connu, une tige de commande 5, d'axe 15, destinée à l'actionnement de moyens de distribution classiques, comme, par exemple, une valve de distribution, ou une pompe de distribution, permettant de conduire le fluide à distribuer, depuis le récipient, vers l'orifice de sortie 6 à travers un i 5 conduit d'alimentation 7, qui traverse la tige 5, et le canal de The support 1 carries, as is known, a control rod 5, of axis 15, intended for the actuation of conventional distribution means, such as, for example, a distribution valve, or a distribution pump, making it possible to lead the fluid to be dispensed, from the container, to the outlet orifice 6 through a supply line i 5 which passes through the rod 5, and the
distribution 4.distribution 4.
Comme cela est visible sur la figure 1, les axes 20 et 15, respectivement de la buse et du conduit 7, sont orthogonaux Le conduit 7 débouche dans la chambre annulaire 8 par une portion 7 a, tangentiellement à ladite chambre 8; la disposition est telle que la mise en rotation du fluide, due à son arrivée tangentielle dans la chambre 8, correspond au sens d'enroulement de l'hélice représentée par le canal de distribution hélicoïdal 4: ainsi, cette mise en rotation du fluide est As can be seen in FIG. 1, the axes 20 and 15, respectively of the nozzle and of the conduit 7, are orthogonal. The conduit 7 opens into the annular chamber 8 through a portion 7 a, tangential to said chamber 8; the arrangement is such that the rotation of the fluid, due to its tangential arrival in the chamber 8, corresponds to the winding direction of the propeller represented by the helical distribution channel 4: thus, this rotation of the fluid is
conservée jusqu'à la sortie du fluide de la buse de distribution. kept until the fluid leaves the dispensing nozzle.
La buse, selon l'invention, minimise les pertes de charge tout au long du chemin parcouru par le fluide, malgré la disposition orthogonale des axes 20 et 15: dans une application simple de l'invention, l'axe 20 est à distance de l'axe 15, comme on peut le voir sur la figure 5, sur laquelle cette distance a été exagérée, à l'échelle de cette figure Tout en minimisant, comme on vient de le voir, les pertes de charges, la buse selon l'invention permet, en outre, de conférer au fluide un mouvement tourbillonnaire qui, comme on le sait, favorise The nozzle according to the invention minimizes the pressure drops along the path traveled by the fluid, despite the orthogonal arrangement of the axes 20 and 15: in a simple application of the invention, the axis 20 is at a distance of axis 15, as can be seen in FIG. 5, over which this distance has been exaggerated, on the scale of this figure While minimizing, as we have just seen, the pressure drops, the nozzle according to l the invention also makes it possible to impart a vortex movement to the fluid which, as is known, promotes
une bonne distribution.good distribution.
La variante de buse, selon l'invention, de la figure 2, comporte un noyau de centrage 3, d'axe 20, qui présente une partie cylindrique et une partie conique, toutes deux ajustées dans l'alésage 10 s qui présente des portions de formes correspondantes, respectivement h et 10 a, ménagées directement dans le bouton-poussoir, la portion conique 10 a débouchant à l'extérieur selon l'orifice 6 Le canal hélicoïdal 4 de distribution est, là aussi, creusé à la surface extérieure s du noyau, 3; les spires du canal 4 qui s'étendent le long de la portion conique 10- , se rapprochent progressivement de l'axe 20 vers l'orifice The nozzle variant, according to the invention, of FIG. 2, comprises a centering core 3, of axis 20, which has a cylindrical part and a conical part, both adjusted in the bore 10 s which has portions of corresponding shapes, respectively h and 10 a, formed directly in the push-button, the conical portion 10 a opening to the outside according to the orifice 6 The helical distribution channel 4 is, here too, hollowed out on the outer surface s of the nucleus, 3; the turns of channel 4 which extend along the conical portion 10-, gradually approach the axis 20 towards the orifice
6, ceci conduisant à une réduction supplémentaire des pertes de charge. 6, this leading to a further reduction in pressure losses.
La première spire 4 a prend naissance au droit de la partie 7 a du conduit 7 qui permet le raccordement dudit conduit 7 au canal 4; selon cette 1 o variante, la section du canal 4 diminue progressivement depuis la spire 4 a jusqu'à la dernière spire qui débouche dans la portion conique 10 a au droit du canal 6: cette diminution progressive de la section du canal 4 permet de comprimer le fluide progressivement, ce qui améliore la distribution. La partie 7 a de raccordement du canal 7 permet progressivement de passer de la section du conduit 7 à celle de la spire The first turn 4a arises at the right of the part 7a of the conduit 7 which allows the connection of said conduit 7 to the channel 4; according to this 1 o variant, the section of the channel 4 gradually decreases from the turn 4 a to the last turn which opens into the conical portion 10 a in line with the channel 6: this gradual decrease in the section of the channel 4 makes it possible to compress the fluid gradually, which improves the distribution. The part 7 a of connection of the channel 7 allows progressively to pass from the section of the conduit 7 to that of the coil
4 a, comme on le voit sur la figure 2 a. 4 a, as seen in Figure 2 a.
Dans une variante non représentée, la section du conduit 7 est égale à In a variant not shown, the section of the duct 7 is equal to
celle de la première spire 4 a.that of the first turn 4 a.
Dans les variantes précédentes, le canal de distribution 4 est creusé à l'interface entre le noyau 3 et l'alésage 10, et s'étend de manière hélicoïdale Dans les variantes qui vont être décrites maintenant, le noyau de centrage est monté dans l'alésage avec un jeu transversal, le canal de distribution étant constitué par ledit jeu In the previous variants, the distribution channel 4 is hollowed out at the interface between the core 3 and the bore 10, and extends helically. In the variants which will now be described, the centering core is mounted in the bore with a transverse clearance, the distribution channel being constituted by said clearance
2 S transversal.2 transverse S.
Ainsi, selon la variante des figures 3 et 4, le bouton- Thus, according to the variant of FIGS. 3 and 4, the button-
poussoir 1 porte un noyau 3 de révolution en forme d'ogive dont la section transversale décroit régulièrement vers l'orifice de sortie 6 ménagé dans le fond d'un manchon 2 a solidarisé au bouton-poussoir 1 et dont l'alésage interne l Oc a une forme complémentaire de celle de la face extérieure du noyau 3 ogival et est située à distance de celle-ci: le jeu ainsi créé entre le noyau 3 et le manchon 2 a constitue le canal de distribution 4; on voit sur la figure 4, repérée par 4 a, l'amorce d'une spire dans la zone o la partie 7 a du conduit 7 rejoint le canal 4; un cloisonnement partiel 14, reliant le noyau de centrage 3 à l'alésage 10 p, est agencé de manière à empêcher le fluide de tourner sur lui-même et à lui conférer une composante axiale de mouvement vers l'orifice ainsi, les particules du fluide ont un mouvement généralement hélicoïdal vers la sortie, autour de l'axe 20, sans qu'il soit nécessaire pusher 1 carries a core 3 of revolution in the form of an ogive, the cross section of which decreases regularly towards the outlet orifice 6 formed in the bottom of a sleeve 2 secured to the push button 1 and whose internal bore l Oc has a shape complementary to that of the outer face of the ogival core 3 and is located at a distance therefrom: the clearance thus created between the core 3 and the sleeve 2 a constitutes the distribution channel 4; we see in Figure 4, identified by 4 a, the initiation of a turn in the area where the part 7 a of the conduit 7 joins the channel 4; a partial partition 14, connecting the centering core 3 to the bore 10 p, is arranged so as to prevent the fluid from turning on itself and to give it an axial component of movement towards the orifice thus, the particles of the fluid have a generally helical movement towards the exit, around the axis 20, without it being necessary

s Selon la variante des figures 6 et 7, la buse de distribution est double, c'est-à-dire qu'elle présente deux orifices de sortie, d'axes 201 et 202; la demi-buse de gauche de la figure 6 est montrée, en s According to the variant of FIGS. 6 and 7, the dispensing nozzle is double, that is to say it has two outlet orifices, with axes 201 and 202; the left half-nozzle of FIG. 6 is shown, in
coupe, sur la figure 7 o l'on voit l'un des deux orifices, l'orifice 61. section, in FIG. 7 where one of the two orifices is seen, the orifice 61.
Chaque demi-buse comprend un noyau de centrage cylindrique 31, 1 o porté par le bouton-poussoir 1, et monté, avec un jeu transversal, dans un alésage désigné dans son ensemble par le repère 100; ledit jeu transversal constitue le canal de distribution 41 (le canal de l'autre demi-buse est désigné par le repère 42 sur la figure 6) Une partie de l'alésage 100 est réalisée dans le bouton-poussoir et comporte une i 5 portion 171 d'amorce de spire, au droit de la partie 71 de raccordement du conduit 7 au canal 41, et une portion 181 déflectrice; les portions 171 et 181 permettent, en combinaison avec la cloison 141 (le repère Each half-nozzle comprises a cylindrical centering core 31, 1 o carried by the push button 1, and mounted, with a transverse clearance, in a bore designated as a whole by the reference 100; said transverse clearance constitutes the distribution channel 41 (the channel of the other half-nozzle is designated by the reference 42 in FIG. 6) Part of the bore 100 is produced in the push-button and has a portion 5 171 of the start of the turn, in line with the part 71 for connecting the conduit 7 to the channel 41, and a deflecting portion 181; the portions 171 and 181 allow, in combination with the partition 141 (the mark
142 désigne sur la figure 6 la cloison correspondante de l'autre demi- 142 designates in FIG. 6 the corresponding partition of the other half
buse), de mettre le fluide en rotation et de lui conférer une composante axiale de mouvement vers l'orifice de sortie Le conduit d'alimentation 7 est prolongé selon deux parties 71, 72, de raccordement aux canaux de distribution 41, 42, séparées par une cloison 19; de préférence, la section du conduit 7 est égale à la somme des sections maximales des nozzle), to put the fluid in rotation and to give it an axial component of movement towards the outlet orifice The supply duct 7 is extended in two parts 71, 72, for connection to the distribution channels 41, 42, separated by a partition 19; preferably, the section of the duct 7 is equal to the sum of the maximum sections of the
canaux 41, 42.channels 41, 42.
L'autre partie de l'alésage'100 est constituée par la surface interne d'un manchon 21, dont le fond porte l'orifice 61; cette surface interne présente une partie conique 161, comprimant le fluide avant sa sortie. La variante de la figure 8 est analogue à celle des figures 6 et 7 mais le noyau 31 est de forme ogivale et l'alésage 100 c du The other part of the bore'100 is constituted by the internal surface of a sleeve 21, the bottom of which carries the orifice 61; this internal surface has a conical portion 161, compressing the fluid before it leaves. The variant of FIG. 8 is similar to that of FIGS. 6 and 7 but the core 31 is of ogival shape and the bore 100 c of the
manchon 21 a une forme analogue.sleeve 21 has a similar shape.
