Description

La présente invention concerne un dispositif de distribution de produit fluide destiné à être associé à un réservoir de produit fluide pour ainsi constituer un distributeur de produit fluide. Ce dispositif de distribution comprend une pompe à précompression et une tête de distribution associée à la pompe pour pouvoir l'actionner. Il s'agit là d'une conception tout à fait classique dans le domaine de la parfumerie, de la cosmétique ou encore de la pharmacie.The present invention relates to a fluid dispenser device intended to be associated with a fluid reservoir to thereby constitute a fluid dispenser. This dispensing device comprises a precompression pump and a dispensing head associated with the pump to be able to actuate it. This is a concept quite classic in the field of perfumery, cosmetics or pharmacy.

De tels dispositifs sont par exemple connus des documents FR 2396595 ou ES 2011142 .Such devices are for example known documents FR 2396595 or ES 2011142 .

En général, la pompe à précompression comprend une tige d'actionnement déplaçable en va-et-vient dans un corps de pompe à l'encontre d'un ressort de rappel. Un piston est monté sur la tige d'actionnement, et le déplacement de ce piston par l'intermédiaire de la tige d'actionnement permet de faire varier le volume d'une chambre de pompe, mettant ainsi le produit fluide contenu dans la chambre sous pression. La pompe à précompression comprend en outre un ressort de précompression qui agit sur le piston pour augmenter la pression dans la chambre de pompe lors de la phase de compression de la chambre. Il s'agit là d'une conception tout à fait classique pour une pompe à précompression.In general, the precompression pump comprises an actuating rod movable back and forth in a pump body against a return spring. A piston is mounted on the actuating rod, and the displacement of this piston through the actuating rod allows to vary the volume of a pump chamber, thereby putting the fluid contained in the chamber under pressure. The precompression pump further comprises a precompression spring which acts on the piston to increase the pressure in the pump chamber during the compression phase of the chamber. This is a quite conventional design for a precompression pump.

D'autre part, la tête de distribution comprend en général un puit d'entrée destiné à être raccordé à l'extrémité supérieure de la tige d'actionnement. La tête comprend également un gicleur de pulvérisation permettant de former un spray à travers un orifice de distribution. La tête est en grande partie formée par un corps de tête qui définit le puit d'entrée ainsi qu'un logement de montage dans lequel est monté le gicleur. Là aussi, il s'agit d'une conception tout à fait classique pour une tête de distribution. En général, le puit d'entrée est relié au logement de montage par un conduit d'alimentation. Ce conduit débouche dans le logement de montage qui forme avec le gicleur un annulaire dans lequel le produit fluide peut circuler. A partir de cet annulaire, le produit fluide s'écoule dans deux ou trois canaux de tourbillonnement qui relient de manière tangentielle une chambre de tourbillonnement centrée sur l'orifice de distribution. Là encore, il s'agit d'une conception tout à fait conventionnelle pour une tête de distribution.On the other hand, the dispensing head generally comprises an inlet well intended to be connected to the upper end of the actuating rod. The head also includes a spray nozzle for forming a spray through a dispensing orifice. The head is largely formed by a head body that defines the inlet well and a mounting housing in which the nozzle is mounted. Again, this is a very classic design for a dispensing head. In general, the inlet well is connected to the mounting housing by a supply conduit. This conduit opens into the mounting housing which forms with the nozzle an annular in which the fluid can circulate. From this ring, the fluid flows in two or three swirl channels that tangentially connect a chamber of swirling centered on the dispensing orifice. Again, this is a completely conventional design for a dispensing head.

Le ressort de précompression présente une raideur qui est de l'ordre de 6 N/mm. Quant au ressort de rappel, sa raideur est de l'ordre de 1,5 N/mm. Cela se traduit par une force d'actionnement sur la tête de distribution qui est de l'ordre de 2 kg environ.The precompression spring has a stiffness which is of the order of 6 N / mm. As for the return spring, its stiffness is of the order of 1.5 N / mm. This results in an actuating force on the dispensing head which is of the order of about 2 kg.

Lorsqu'une telle pompe à précompression est associée à une telle tête de distribution, on obtient un spray de bonne qualité, mais il faut appuyer à l'aide d'un doigt, en général l'index, sur la tête de distribution avec une force d'actionnement importante de l'ordre de 2 kg, voire plus. Il s'ensuit que l'actionnement de ce dispositif de distribution nécessite un degré d'effort conséquent, de sorte que l'actionnement peut être qualifié de « dur ». De plus en plus souvent, les utilisateurs souhaitent que l'actionnement du dispositif de distribution soit plus souple ou doux : en d'autres termes, la force d'actionnement doit être abaissée. Cependant, un abaissement de la force d'actionnement conduit à une qualité de spray médiocre, voire inadmissible. Au lieu d'avoir un spray, on obtient un jet formé de gouttelettes de taille excessive.When such a precompression pump is associated with such a dispensing head, a spray of good quality is obtained, but it is necessary to press with a finger, generally the index, on the dispensing head with a large actuating force of the order of 2 kg or more. It follows that the actuation of this dispensing device requires a degree of effort, so that the actuation can be described as "hard". Increasingly, users want the actuation of the dispensing device to be more flexible or soft: in other words, the actuating force must be lowered. However, a lowering of the actuating force leads to a mediocre quality of spray, or even inadmissible. Instead of having a spray, we get a jet of droplets of excessive size.

Par conséquent, on est en présence de deux exigences qui semblent à priori antagonistes, à savoir d'un côté réduire la force d'actionnement exercée sur la tête de distribution, et de l'autre côté obtenir un spray de bonne qualité. En effet, si l'on abaisse la force d'actionnement la qualité du spray est médiocre, et si l'on veut obtenir une bonne qualité de spray, et si l'on veut obtenir une bonne qualité de spray, il faut maintenir la force d'actionnement à un niveau élevé de l'ordre de 2 kg ou plus.Therefore, there are two requirements that seem a priori antagonistic, namely on one side reduce the actuating force exerted on the dispensing head, and on the other hand get a spray of good quality. Indeed, if we lower the actuation force the quality of the spray is poor, and if we want to get a good spray quality, and if we want to get a good spray quality, we must maintain the actuation force at a high level of the order of 2 kg or more.

La présente invention a pour but d'apporter une solution permettant de concilier ces deux exigences apparemment antagonistes dans un dispositif de distribution présentant des caractéristiques particulières. En l'occurrence, la présente invention propose un dispositif de distribution de produit fluide comprenant une pompe à précompression et une tête de distribution, la pompe comprenant une tige d'actionnement déplaçable en va-et-vient et un ressort de précompression pour augmenter la pression dans une chambre de pompe, la tête comprenant un puits d'entrée destiné à être raccordé à la tige d'actionnement et un gicleur pour former un spray à travers un orifice de distribution, le gicleur étant monté dans un logement de montage, caractérisé en ce que le ressort de précompression présente une raideur inférieure à environ 3 N/mm, par exemple de l'ordre de 1 à 3 N/mm, et au moins deux conduits d'alimentation relient chacun le puits d'entrée au logement de montage. C'est de manière tout à fait empirique que l'on a constaté une excellente qualité de spray lorsque ces deux caractéristiques sont combinées, à savoir une faible raideur pour le ressort de précompression et une pluralité de conduits d'alimentation. Un spray de qualité exceptionnelle a été constaté lorsque le ressort de précompression présente une raideur de l'ordre de 2N/mm.The present invention aims to provide a solution to reconcile these two seemingly antagonistic requirements in a dispensing device having particular characteristics. In this case, the present invention provides a fluid dispensing device comprising a precompression pump and a dispensing head, the pump comprising a reciprocating actuating rod and a precompression spring for increasing the pressure. pressure in a room pump, the head comprising an inlet well adapted to be connected to the actuating rod and a nozzle for forming a spray through a dispensing orifice, the nozzle being mounted in a mounting housing, characterized in that the spring precompression has a stiffness less than about 3 N / mm, for example of the order of 1 to 3 N / mm, and at least two supply ducts each connect the inlet well to the mounting housing. It is entirely empirical that excellent spray quality has been found when these two characteristics are combined, namely a low stiffness for the precompression spring and a plurality of supply ducts. A spray of exceptional quality was found when the precompression spring has a stiffness of the order of 2N / mm.

Selon une autre caractéristique avantageuse de l'invention, la pompe comprend un ressort de rappel pour ramener la tige d'actionnement en position de repos, la force d'actionnement pour enfoncer la tige d'actionnement à partir de sa position de repos à l'encontre des ressorts de rappel et de précompression est sensiblement inférieure à 2kg, avantageusement égale à 1,5kg +/- 0,2kg. Comparé à une pompe à précompression conventionnelle, cela procure un actionnement souple ou doux, que l'on ressent de manière très prononcée lorsque l'on actionne la tête de distribution. L'effet surprenant réside dans le fait que la qualité du spray est remarquable, alors que la force d'actionnement est faible.According to another advantageous characteristic of the invention, the pump comprises a return spring for returning the actuating rod to the rest position, the actuating force for driving the actuating rod from its rest position to the rest position. against the return springs and precompression is substantially less than 2kg, preferably equal to 1.5kg +/- 0.2kg. Compared with a conventional precompression pump, this provides a soft or smooth actuation, which is felt very pronounced when operating the dispensing head. The surprising effect lies in the fact that the quality of the spray is remarkable, while the actuating force is low.

Selon une autre caractéristique avantageuse de l'invention, les conduits d'alimentation présentent chacun une section de l'ordre de 0,3 à 0,7 mm2.According to another advantageous characteristic of the invention, the supply ducts each have a section of the order of 0.3 to 0.7 mm 2 .

Selon un autre aspect avantageux de l'invention, un système de tourbillonnement est prévu en amont de l'orifice de distribution, ce système comprenant au moins deux canaux de tourbillonnement reliant tangentiellement une chambre de tourbillonnement centrée sur l'orifice de pulvérisation, chaque canal de tourbillonnement étant alimenté par un conduit d'alimentation. Une explication à la bonne qualité de spray obtenue avec l'invention réside en partie dans le fait que chaque canal de tourbillonnement est alimenté par son propre conduit d'alimentation directement à partir du puit d'entrée, de manière à obtenir une parfaite symétrie d'alimentation des canaux de tourbillonnement. La faiblesse de la force d'actionnement est ainsi compensée par une perte de charge réduite dans la tête de distribution.According to another advantageous aspect of the invention, a swirling system is provided upstream of the dispensing orifice, this system comprising at least two swirling channels tangentially connecting a swirl chamber centered on the spray orifice, each channel swirling being fed by a supply duct. An explanation of the good quality of the spray obtained with the invention resides in part in the fact that each Whirling is fed by its own feed duct directly from the inlet well, so as to obtain a perfect symmetry supply of the swirling channels. The weakness of the actuating force is thus compensated by a reduced pressure drop in the dispensing head.

Selon une forme de réalisation pratique avantageuse, une broche s'étend dans le logement de montage, la broche définissant une paroi latérale et une paroi frontale, le gicleur présentant une forme de godet comprenant une paroi sensiblement cylindrique dont une extrémité est obturée par une paroi de distribution formant un orifice de pulvérisation, le gicleur étant monté selon un axe X dans le logement de montage avec sa paroi cylindrique engagée autour de la broche et sa paroi de distribution en butée axiale contre la paroi frontale de la broche, la paroi cylindrique du gicleur étant en contact étanche avec la paroi latérale de la broche de manière à définir au moins deux sections de liaison reliant chacune un conduit d'alimentation à un canal de tourbillonnement. Avantageusement, la paroi frontale de la broche forme au moins deux canaux de tourbillonnement reliant tangentiellement une chambre de tourbillonnement centrée sur l'orifice de pulvérisation. Avantageusement, la paroi cylindrique du gicleur est en contact étanche avec la paroi latérale de la broche au niveau d'au moins deux zones d'étanchéité qui s'étendent de manière sensiblement axiale à partir des conduits jusqu'aux canaux de manière à former les deux sections de liaison. De préférence, les zones d'étanchéité sont formées par des nervures axiales de la broche en contact de la paroi cylindrique du gicleur.According to an advantageous practical embodiment, a pin extends in the mounting housing, the pin defining a side wall and a front wall, the nozzle having a cup shape comprising a substantially cylindrical wall, one end of which is closed by a wall distribution nozzle forming a spray orifice, the nozzle being mounted along an axis X in the mounting housing with its cylindrical wall engaged around the spindle and its distribution wall in axial abutment against the front wall of the spindle, the cylindrical wall of the nozzle being in sealing contact with the side wall of the pin so as to define at least two connecting sections each connecting a supply duct to a swirl channel. Advantageously, the front wall of the spindle forms at least two swirl channels tangentially connecting a swirl chamber centered on the spray orifice. Advantageously, the cylindrical wall of the nozzle is in sealing contact with the side wall of the pin at at least two sealing zones which extend substantially axially from the ducts to the channels so as to form the two connecting sections. Preferably, the sealing zones are formed by axial ribs of the pin in contact with the cylindrical wall of the nozzle.

Les nervures axiales, éventuellement combinées aux joncs d'étanchéité radiaux, permettent ainsi de délimiter deux sections de liaison distinctes permettant de relier chacune un conduit d'alimentation à un canal de tourbillonnement.The axial ribs, possibly combined with the radial sealing rods, thus make it possible to define two distinct connection sections making it possible to connect each one of a supply duct to a swirl duct.

Selon un autre aspect intéressant de l'invention, le puits d'entrée s'étend selon un axe Y qui est transversale à l'axe X, de sorte que les conduits d'alimentation se raccordent sur la hauteur du puits, les hauteurs des deux conduits dans le puits selon l'axe Y étant identiques. Ainsi, le produit fluide présent dans le puits d'entrée s'écoule de manière identique homogène et équivalente, sans priorité, dans les conduits d'alimentation. On assure ainsi une alimentation équilibrée parfaitement symétrique des canaux de tourbillonnement. Les trajets d'écoulement du produit fluide depuis l'entrée des conduits d'alimentation jusqu'à l'orifice de pulvérisation à travers les conduits d'alimentation, les sections de liaison, les canaux de tourbillonnement et la chambre de tourbillonnement sont identiques en longueur et en configuration.According to another interesting aspect of the invention, the inlet well extends along an axis Y which is transverse to the axis X, so that the supply ducts are connected to the height of the well, the heights of the two conduits in the well along the Y axis are identical. So, the Fluid product present in the inlet well flows homogeneously and equivalently, without priority, into the feed ducts. This ensures a balanced diet perfectly symmetrical swirl channels. The flow paths of the fluid from the inlet of the supply ducts to the spray port through the supply ducts, the connecting sections, the swirl channels and the swirl chamber are identical. length and in configuration.

Selon un autre aspect de l'invention, le logement et la paroi cylindrique du gicleur présentent une symétrie de révolution autour de l'axe X. Ainsi, il n'est pas nécessaire d'orienter le gicleur angulairement par rapport à l'axe X pour l'insérer à l'intérieur de son logement de montage. Etant donné que l'orientation des canaux de tourbillonnement et des sections de liaison est imposée par la broche qui est fixe par rapport au logement de montage, le gicleur, qui est symétrique de révolution, ne peut pas intervenir et modifier leur orientation.According to another aspect of the invention, the housing and the cylindrical wall of the nozzle have a symmetry of revolution about the X axis. Thus, it is not necessary to orient the nozzle angularly with respect to the X axis. to insert it inside its mounting slot. Since the orientation of the swirl channels and connecting sections is imposed by the pin which is fixed relative to the mounting housing, the nozzle, which is symmetrical of revolution, can not intervene and change their orientation.

L'invention repose ainsi que l'association de deux caractéristiques, à savoir faible raideur du ressort de précompression et pluralité de conduits d'alimentation, permettant d'adoucir l'actionnement d'un dispositif de distribution sans porter préjudice à la qualité de son spray.The invention is based on the combination of two characteristics, namely low stiffness of the precompression spring and a plurality of supply ducts, making it possible to soften the actuation of a dispensing device without prejudicing the quality of its sound. spray.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemples non limitatifs un mode de réalisation de l'invention.The invention will now be further described with reference to the accompanying drawings giving by way of non-limiting examples an embodiment of the invention.

On se référera indifféremment aux figures 1 à 4 pour décrire en détail les pièces constitutives, le mode d'assemblage ainsi que les avantages d'une tête de distribution réalisée selon un mode de réalisation non limitatif de l'invention.We will refer indifferently to Figures 1 to 4 to describe in detail the component parts, the method of assembly and the advantages of a dispensing head made according to a non-limiting embodiment of the invention.

La tête de distribution comprend deux pièces constitutives essentielles, à savoir un corps de tête 1 et un gicleur 4. Ces deux pièces peuvent être réalisées par injection moulage de matière plastique. Le corps de tête 1 est de préférence réalisé de manière monobloc : il peut cependant être réalisé à partir de plusieurs pièces assemblées les unes aux autres. Il en est de même pour le gicleur 4 qui est de préférence réalisé de manière monobloc.The dispensing head comprises two essential components, namely a head body 1 and a nozzle 4. These two parts can be made by injection molding of plastics material. The head body 1 is preferably made in one piece: it can however be made from several parts assembled to each other. It is the same for the nozzle 4 which is preferably made integrally.

Le corps de tête 1 comprend une jupe périphérique sensiblement cylindrique 11 qui est obturée à son extrémité supérieure par un plateau 12. Le corps de tête 1 comprend également un manchon de raccordement 13 qui s'étend ici de manière concentrique à l'intérieur de la jupe périphérique 11. Le manchon de raccordement 13 s'étend vers le bas à partir du plateau 12. Il définit intérieurement un puits d'entrée 14 qui est ouvert vers le bas et obturé à son extrémité supérieure par le plateau 12. Le manchon de raccordement 13 est destiné à être monté sur l'extrémité libre d'une tige d'actionnement d'un organe de distribution tel qu'une pompe ou une valve. La tige d'actionnement (non représentée) est déplaçable en va-et-vient selon l'axe Y. La tige d'actionnement est creuse de manière à définir un conduit de refoulement en communication avec la chambre de dosage de la pompe ou de la valve. Le puits d'entrée 14 s'étend dans le prolongement de la tige d'actionnement de sorte que le produit fluide issu de la chambre de dosage peut s'écouler dans le puits d'entrée 14. Le manchon de raccordement 13 est raccordé à la jupe périphérique 11 par un bloc de liaison 16, visible sur la figure 2. Ce bloc 16 s'étend sous le plateau 12 selon un axe X, qui est ici perpendiculaire à l'axe Y. Il pourrait en être autrement. Le bloc de liaison 16 définit intérieurement deux conduits d'alimentation 15 ainsi qu'un logement de montage axial 2. Le bloc 16 définit également une broche 3 qui fait saillie à l'intérieur du logement de montage 2. Les deux conduits d'alimentation 15 relient le puits d'entrée 14 au logement de montage 2, comme on peut le voir très clairement sur la figure 2. On peut également remarquer sur cette figure que les deux conduits d'alimentation 15 sont reliés au puits d'entrée 14 à la même hauteur sur l'axe Y. Les deux conduits d'alimentation 15 ont de préférence une section identique et une configuration identique. On peut dire qu'ils sont disposés de manière symétrique par rapport à l'axe X. La broche 3 est également disposée sur l'axe X. Le logement de montage axial 2 est de configuration globale cylindrique, définissant ainsi une paroi interne 21 qui est sensiblement cylindrique ainsi qu'une paroi de fond 22 de forme complexe. Les conduits d'alimentation 15 débouchent dans le logement de montage 2 au niveau de cette paroi de fond 22. Ceci est plus visible sur la figure 3. On peut également remarquer sur cette figure que la paroi interne 21 présente des profils d'accrochage permettant un meilleur maintien du gicleur, comme on le verra ci-après.The head body 1 comprises a substantially cylindrical peripheral skirt 11 which is closed at its upper end by a plate 12. The head body 1 also comprises a connecting sleeve 13 which here concentrically extends inside the body. peripheral skirt 11. The connecting sleeve 13 extends downwardly from the plate 12. It defines internally an inlet well 14 which is open downwards and closed at its upper end by the plate 12. connection 13 is intended to be mounted on the free end of an actuating rod of a dispensing member such as a pump or a valve. The actuating rod (not shown) is movable back and forth along the Y axis. The actuating rod is hollow so as to define a discharge pipe in communication with the dosing chamber of the pump or of the pump. the valve. The inlet well 14 extends in the extension of the actuating rod so that the fluid product from the dosing chamber may flow into the inlet well 14. The connecting sleeve 13 is connected to the peripheral skirt 11 by a connecting block 16, visible on the figure 2 . This block 16 extends under the plate 12 along an axis X, which is here perpendicular to the axis Y. It could be otherwise. The connecting block 16 internally defines two supply ducts 15 and an axial mounting housing 2. The block 16 also defines a pin 3 which protrudes inside the mounting housing 2. The two supply ducts 15 connect the inlet well 14 to the mounting housing 2, as can be seen very clearly on the figure 2 . It may also be noted in this figure that the two supply ducts 15 are connected to the inlet well 14 at the same height on the Y axis. The two supply ducts 15 preferably have an identical section and identical configuration. . It can be said that they are arranged symmetrically with respect to the axis X. The spindle 3 is also arranged on the axis X. The axial mounting housing 2 is of cylindrical overall configuration, thus defining an internal wall 21 which is substantially cylindrical and a bottom wall 22 of complex shape. The supply ducts 15 open into the mounting housing 2 at this bottom wall 22. This is more visible on the figure 3 . It can also be noted in this figure that the inner wall 21 has hooking profiles for better maintenance of the nozzle, as will be seen below.

La broche 3 fait donc saillie dans le logement de montage 2 à partir de la paroi de fond 22. Les conduits d'alimentation 15 débouchent dans le logement de montage 2 de part et d'autre de la broche 3, comme visible sur la figure 3. La broche 3 comprend une paroi latérale 31 qui s'étend à partir de la paroi de fond 22 jusqu'à une paroi frontale 32 qui définit l'extrémité libre de la broche. La broche s'étend dans le logement sans venir en contact avec sa paroi interne 21. En d'autres termes, la paroi latérale 31 de la broche n'est pas en contact de la paroi interne 21 du logement. La paroi frontale 32 de la broche ne fait pas saillie hors du logement : au contraire, elle reste à distance à l'intérieur du logement. Ceci est clairement visible sur la figure 2. La paroi frontale 32 de la broche est formée avec un profil en creux qui définit deux canaux de tourbillonnement tangentiels 35 qui se raccordent de manière tangentielle à une chambre de tourbillonnement centrale 36 qui est centrée sur l'axe X. Les canaux 35 débouchent sur la paroi latérale 31 de la broche, comme on peut le voir sur la figure 1. D'autre part, la paroi latérale 31 de la broche est formée avec quatre nervures 33 qui s'étendent avantageusement de manière axiale selon l'axe X. Ces nervures 33 s'étendent depuis la paroi frontale 32 jusqu'à la paroi de fond 22 du logement 2. Au niveau où elles se raccordent avec la paroi de fond 22, chaque nervure 33 se prolonge sous la forme d'un jonc d'étanchéité radial 23 qui s'étend, avantageusement en biais, jusqu'en contact de la paroi interne 21 du logement de montage 2. De manière globale, la broche 3 présente une section transversale verticale sensiblement rectangulaire, ou du moins allongée : les quatre coins du rectangle étant formés par les nervures 33. Les deux conduits d'alimentation 15 s'étendent sur les côtés verticaux longs du rectangle formé par la broche. En variante, la broche 3 peut également présenter une section ronde ou circulaire avec quatre nervures 33.The pin 3 thus projects into the mounting housing 2 from the bottom wall 22. The supply ducts 15 open into the mounting housing 2 on either side of the pin 3, as shown in FIG. figure 3 . Pin 3 includes a side wall 31 which extends from the bottom wall 22 to a front wall 32 which defines the free end of the pin. The pin extends into the housing without coming into contact with its inner wall 21. In other words, the side wall 31 of the pin is not in contact with the inner wall 21 of the housing. The front wall 32 of the spit does not project out of the housing: on the contrary, it remains at a distance inside the housing. This is clearly visible on the figure 2 . The front wall 32 of the spindle is formed with a recessed profile which defines two tangential swirl channels 35 which are tangentially connected to a central swirl chamber 36 which is centered on the X axis. The channels 35 open on the side wall 31 of the spindle, as can be seen in FIG. figure 1 . On the other hand, the side wall 31 of the spindle is formed with four ribs 33 which advantageously extend axially along the axis X. These ribs 33 extend from the front wall 32 to the bottom wall 22 of the housing 2. At the level where they are connected with the bottom wall 22, each rib 33 is extended in the form of a radial sealing ring 23 which extends, advantageously at an angle, to contact the internal wall 21 of the mounting housing 2. Overall, the pin 3 has a substantially rectangular, or at least elongated vertical cross section: the four corners of the rectangle being formed by the ribs 33. The two supply ducts 15 ' extend on the long vertical sides of the rectangle formed by the spindle. Alternatively, the pin 3 may also have a round or circular section with four ribs 33.

Le gicleur 4 présente une configuration sensiblement conventionnelle sous la forme d'un godet, comprenant ainsi une paroi sensiblement cylindrique 41 qui est ouverte à une extrémité et fermée à son extrémité opposée par une paroi de distribution 42 au niveau de laquelle est formé un orifice de pulvérisation 43. La paroi cylindrique 41 définit au niveau de son extrémité ouverte un bord annulaire libre 44. Le gicleur 4 est une pièce qui présente de préférence une symétrie axiale de révolution autour de l'axe X, comme présenté sur la figure 1. En d'autres termes, le gicleur 4 n'a pas besoin d'être orienté angulairement avant sa présentation devant l'entrée du logement de montage axial 2. Ceci représente un grand avantage par rapport au document de l'art antérieur EP-0 802 827 . Ainsi, le gicleur 4 peut être engagé axialement sans orientation particulière dans le logement de montage axial 2, comme représenté sur la figure 1. Une fois le montage axial terminé, le gicleur 4 est dans la configuration représentée sur la figure 2. Sa paroi de distribution 42 vient en contact étanche avec la paroi frontale 32 de la broche 3 de manière à isoler et compléter les canaux de tourbillonnement 35 et la chambre de tourbillonnement 36. On peut même constater sur la figure 2 que la paroi de distribution 42 forme intérieurement une partie 46 de la chambre de tourbillonnement en complément de celle 36 formée par la broche. D'autre part, la paroi cylindrique 41 du gicleur 4 vient en contact serrant et étanche avec la paroi latérale 21 du logement 21 ainsi qu'avec les nervures 33 de la broche 3, comme visible sur la figure 4. Ainsi, la broche 3 et la paroi cylindrique 41 du gicleur 4 définissent entre eux quatre espaces, à savoir deux sections de liaison 34 et deux espaces morts E. Les sections de liaison 34 relient les conduits d'alimentation 15 aux canaux de tourbillonnement 35. Ceci est visible sur la figure 2. On peut également dire que les sections de liaison 34 prolongent les conduits d'alimentation 15 jusqu'au niveau des canaux de tourbillonnement 35. D'autre part, les espaces morts E sont isolés et ne communiquent pas avec l'extérieur. On peut également noter que le bord annulaire libre 44 du gicleur 4 vient en contact avec les joncs radiaux 23 pour compléter l'étanchéité au niveau du fond 22 du logement.The nozzle 4 has a substantially conventional configuration in the form of a bucket, thus comprising a substantially cylindrical wall 41 which is open at one end and closed at its opposite end by a distribution wall 42 at which is formed an orifice of Spraying 43. The cylindrical wall 41 defines at its open end a free annular edge 44. The nozzle 4 is a part which preferably has an axial symmetry of revolution about the X axis, as shown on the diagram. figure 1 . In other words, the nozzle 4 does not need to be oriented angularly before its presentation in front of the inlet of the axial mounting housing 2. This represents a great advantage over the document of the prior art EP-0 802 827 . Thus, the nozzle 4 can be axially engaged without particular orientation in the axial mounting housing 2, as shown in FIG. figure 1 . Once the axial assembly is complete, the nozzle 4 is in the configuration shown on the figure 2 . Its distribution wall 42 comes into sealed contact with the front wall 32 of the pin 3 so as to isolate and complete the swirling channels. 35 and the swirl chamber 36. It can even be seen on the figure 2 that the distribution wall 42 internally forms a portion 46 of the swirl chamber in addition to that 36 formed by the spindle. On the other hand, the cylindrical wall 41 of the nozzle 4 comes into tight and tight contact with the side wall 21 of the housing 21 as well as with the ribs 33 of the pin 3, as visible on FIG. figure 4 . Thus, the pin 3 and the cylindrical wall 41 of the nozzle 4 define between them four spaces, namely two connecting sections 34 and two dead spaces E. The connecting sections 34 connect the supply ducts 15 to the swirl channels 35. This is visible on the figure 2 . It can also be said that the connecting sections 34 extend the supply ducts 15 to the level of the swirling channels 35. On the other hand, the dead spaces E are isolated and do not communicate with the outside. It may also be noted that the free annular edge 44 of the nozzle 4 comes into contact with the radial rods 23 to complete the seal at the bottom 22 of the housing.

On peut ainsi dire que le gicleur 4 vient en contact de la broche 3 en définissant plusieurs zones d'étanchéité Z formées par les nervures 33 venant en contact de la paroi latérale 41 du gicleur. Ceci est clairement visible sur la figure 4. On peut même imaginer que les nervures 33 soient légèrement déformées par la paroi latérale 41 pour améliorer l'étanchéité. Les zones d'étanchéité Z sont ici au nombre de quatre, mais on peut également envisager de réaliser la tête de distribution selon l'invention avec seulement deux zones d'étanchéité, ou au contraire avec trois ou même plus de quatre zones d'étanchéité. On peut par exemple remplacer deux nervures 33 par un segment de cylindre venant en contact intime avec la paroi cylindrique 41 du gicleur. Dans ce cas, il n'y aurait pas d'espaces morts E. Le présent mode de réalisation est avantageux, car la forme rectangulaire de la broche permet de définir deux sections de liaison en rapport avec les conduits d'alimentation 15.It can thus be said that the nozzle 4 comes into contact with the pin 3 by defining a plurality of sealing zones Z formed by the ribs 33 coming into contact with the lateral wall 41 of the nozzle. This is clearly visible on the figure 4 . One can even imagine that the ribs 33 are slightly deformed by the side wall 41 to improve the seal. The sealing zones Z are here four in number, but it is also possible to envisage making the dispensing head according to the invention with only two sealing zones, or on the contrary with three or even more than four sealing zones. . For example, two ribs 33 may be replaced by a cylinder segment which comes into intimate contact with the cylindrical wall 41 of the nozzle. In this case, there would be no dead spaces E. The present embodiment is advantageous because the rectangular shape of the spindle makes it possible to define two connecting sections in relation to the supply ducts 15.

Il faut remarquer que les deux canaux de tourbillonnement 35 sont ainsi alimentés de manière symétrique, équilibrée et identique par les deux conduits d'alimentation 15 et les deux sections de liaison 34. Ceci provient du fait que les conduits 15 et des sections de liaison 34 sont disposés de manière parfaitement symétrique de part et d'autre de l'axe X. De plus, étant donné que les deux conduits d'alimentation 15 partent du puits d'entrée 14 à la même hauteur sur l'axe Y, on garantit une symétrie d'alimentation parfaite en produit fluide des deux canaux de tourbillonnement, et de ce fait de la chambre de tourbillonnement 36. Chaque canal de tourbillonnement 35 apporte la même quantité de produit fluide avec la même vitesse à la chambre de tourbillonnement 36, favorisant ainsi la formation d'un vortex parfait. Il s'ensuit que la qualité de la pulvérisation à travers l'orifice de pulvérisation 43 est optimum.It should be noted that the two swirl channels 35 are thus fed symmetrically, balanced and identical by both supply ducts 15 and the two connecting sections 34. This is because the ducts 15 and connecting sections 34 are arranged perfectly symmetrically on either side of the X axis. that the two supply ducts 15 start from the inlet well 14 at the same height on the Y axis, one guarantees a symmetry of perfect fluid supply of the two swirl channels, and thus of the chamber of Whirling 36. Each vortex channel 35 provides the same amount of fluid with the same velocity to the vortex chamber 36, thereby promoting the formation of a perfect vortex. It follows that the quality of the spray through the spray orifice 43 is optimum.

Sans sortir du cadre de l'invention, il est envisageable de réaliser une tête de distribution comportant par exemple quatre canaux de tourbillonnement alimentés de manière symétrique par deux conduits d'alimentation et deux sections de liaison : chaque paire de canal de tourbillonnement étant ainsi alimentée par un conduit d'alimentation et une section de liaison. Il est également envisageable de réaliser une tête de distribution avec trois canaux de tourbillonnement alimentés par trois conduits d'alimentation et trois sections de liaison.Without departing from the scope of the invention, it is conceivable to make a dispensing head comprising, for example, four swirling channels fed symmetrically by two supply ducts and two connecting sections: each pair of swirling channel thus being fed by a supply duct and a connecting section. It is also conceivable to make a dispensing head with three swirl channels fed by three supply ducts and three connecting sections.

Optionnellement, le corps de tête 1 peut être engagé dans une capsule d'habillage 5 comprenant une ouverture latérale 54 pour le passage du gicleur 4.Optionally, the head body 1 can be engaged in a covering cap 5 comprising a lateral opening 54 for the passage of the nozzle 4.

On se référera maintenant aux figures 5 et 6 qui représentent deux variantes de réalisation de la tête de distribution de l'invention. La différence essentielle par rapport aux modes de réalisation des figures 1 à 4 réside dans le fait que les conduits d'alimentation 15 ne sont pas situés de manière diamétralement opposée de chaque côté de la broche 3, mais de manière rapprochée au-dessus de la broche 3. Les deux conduits 15 ne sont séparés que par une seule nervure axiale 33 au niveau de la partie haute de la broche et par deux autres nervures axiales 33 dans la partie basse de la broche. Les conduits d'alimentation 15 peuvent communiquer avec les canaux de tourbillonnement 35 par l'intermédiaire de deux espaces de liaison 37 formés autour de la broche 3 dans le logement de montage 2. On peut également remarquer sur la figure 5 que la broche 3 n'est pas circulaire, mais plutôt oblongue dans le sens vertical, avec une nervure 33 située en partie haute, et deux autres nervures situées latéralement en partie basse. Les canaux de tourbillonnement 35 débutent au niveau de parois planes de la broche adjacentes aux espaces de liaison 37.We will now refer to Figures 5 and 6 which represent two variants of embodiment of the dispensing head of the invention. The essential difference compared to the embodiments of the Figures 1 to 4 resides in the fact that the supply ducts 15 are not located diametrically opposite each side of the pin 3, but in a close manner above the pin 3. The two ducts 15 are separated only by one axial rib 33 at the upper part of the spindle and two other axial ribs 33 in the lower part of the spindle. The supply ducts 15 can communicate with the swirl channels 35 via two connection spaces 37 formed around pin 3 in the mounting housing 2. It can also be seen on the figure 5 that the pin 3 is not circular, but rather oblong in the vertical direction, with a rib 33 located in the upper part, and two other ribs located laterally in the lower part. The swirl channels 35 start at flat walls of the spindle adjacent to the connecting spaces 37.

En se référant à la figure 6, on peut tout de suite constater que la broche 3 est circulaire et comprend trois nervures axiales 33 situées sensiblement au même niveau que celles sur la figure 5. Les deux conduits d'alimentation 15 sont également disposés de manière identique dans la partie haute du logement 2 au-dessus de la broche 3. A la place des espaces de liaison 37, il est prévu deux évidements de liaison 38 formés par la broche 3. Ces évidements 38 se prolongent ensuite en formant les canaux de tourbillonnement 35.Referring to the figure 6 , it can immediately be seen that the pin 3 is circular and comprises three axial ribs 33 located substantially at the same level as those on the figure 5 . The two supply ducts 15 are also arranged identically in the upper part of the housing 2 above the pin 3. In place of the connection spaces 37, there are two connection recesses 38 formed by the pin 3 These recesses 38 then extend by forming the swirl channels 35.

La tête de distribution qui vient d'être décrite en référence aux figures 1 à 6 est destinée à être montée sur une pompe ou sur une valve pour ainsi constituer un dispositif de distribution. En se référant maintenant à la figure 7, on voit un dispositif de distribution particulier comprenant une tête de distribution T selon l'invention associée à une pompe à précompression 6. Cette pompe 6 présente une configuration générale sensiblement classique avec un corps de pompe 61 définissant en partie basse un siège pour un clapet 63 et en partie haute une collerette 64 qui fait saillie radialement vers l'extérieur. Cette collerette 64 peut servir à l'accrochage d'un système de fixation 7, qui peut par exemple se présenter sous la forme d'une bague à sertir. On peut bien entendu envisager d'autres formes de système de fixation 7 à être associé à la pompe 6. Le système de fixation 7 est associé à un joint de col 8 permettant de réaliser une étanchéité avec le col d'un réservoir de produit fluide non représenté. Le corps de pompe 61 définit intérieurement un fût de coulissement cylindrique 62 dans lequel coulisse de manière étanche un piston 66 doté d'une lèvre d'étanchéité 67. Le piston 66 est monté sur une tige d'actionnement 65 qui est sollicitée en position de repos par un ressort de rappel 68. Pour créer la précompression, le piston 66 est sollicité par un ressort de précompression 69. Le piston 66 est monté mobile sur la tige d'actionnement 65 de manière à pouvoir démasquer un passage de sortie pour le produit fluide comprimé dans la chambre de pompe 60. En d'autres termes, le piston 66 remplit une fonction de clapet de sortie en dégageant un passage de sortie lorsque la pression à l'intérieur de la chambre de pompe 60 atteint une valeur prédéterminée. Le ressort de précompression 69 sollicite le piston 66 dans la position fermée du clapet de sortie. Ainsi, le déplacement du piston 66 sur la tige d'actionnement 65 ne peut se faire que lorsque la pression à l'intérieur de la chambre 60 est suffisante pour comprimer le ressort de précompression 69.The dispensing head which has just been described with reference to Figures 1 to 6 is intended to be mounted on a pump or a valve so as to constitute a dispensing device. Referring now to the figure 7 , we see a particular dispensing device comprising a dispensing head T according to the invention associated with a precompression pump 6. This pump 6 has a substantially conventional general configuration with a pump body 61 defining in the lower part a seat for a valve 63 and in the upper part a collar 64 which projects radially outwards. This flange 64 can be used to attach a fastening system 7, which may for example be in the form of a crimp ring. It is of course possible to envisage other forms of fastening system 7 to be associated with the pump 6. The fastening system 7 is associated with a neck seal 8 making it possible to seal the neck of a fluid reservoir not shown. The pump body 61 internally defines a cylindrical sliding barrel 62 in which a piston 66 with a sealing lip 67 is slidably sealed. The piston 66 is mounted on an actuating rod 65 which is urged into the rest by a return spring 68. To create the precompression, the piston 66 is biased by a precompression spring 69. The piston 66 is movably mounted on the actuating rod 65 so as to be able to unmask an outlet passage for the compressed fluid product in the pump chamber 60. In other words, the Piston 66 performs an outlet valve function by clearing an outlet passage when the pressure inside the pump chamber 60 reaches a predetermined value. The precompression spring 69 urges the piston 66 into the closed position of the outlet valve. Thus, the displacement of the piston 66 on the actuating rod 65 can be done only when the pressure inside the chamber 60 is sufficient to compress the precompression spring 69.

Dans une pompe à précompression conventionnelle, le ressort de rappel 68 présente une raideur de l'ordre de 1,52 N/mm (155 g/mm). Quant au ressort de précompression, il présente en général une raideur de l'ordre de 6,17 N/mm (629 g/mm). Cependant, il a été découvert de manière empirique qu'il est possible de réduire considérablement la raideur du ressort de précompression 69, sans détériorer la qualité du spray au niveau de la tête de distribution T selon l'invention. La raideur du ressort de précompression agit directement sur la résistance à l'actionnement : en réduisant la raideur du ressort, l'actionnement de la pompe est plus doux ou souple. Une raideur de l'ordre de 2 N/mm est suffisante pour conserver un spray de bonne qualité. Des essais très concluants ont été effectués avec un ressort de précompression dont la raideur est de 2,03 N/mm (207 g/mm). Cependant, il est même possible d'abaisser la raideur du ressort de précompression 69 jusqu'à environ 1 N/mm, tout en conservant une qualité de spray acceptable. Avec une raideur de l'ordre de 2 N/mm, la force d'actionnement nécessaire pour actionner la tête de distribution T est de l'ordre de 1,5 kg plus ou moins 200 g. La réduction de la raideur du ressort de précompression 69 tout en conservant une qualité de spray acceptable peut s'expliquer par le fait qu'il y a plusieurs conduits d'alimentation 15 qui relient directement le puit d'entrée 14 au logement de montage 2 dans lequel est engagé le gicleur 4. De préférence, il y a deux conduits d'alimentation 15 qui relient chacun un canal de tourbillonnement 35 par l'intermédiaire d'une section de liaison 34 formée entre la broche 3 et le gicleur 4, comme cela a été expliqué précédemment. La symétrie d'alimentation des canaux de tourbillonnement par des conduits d'alimentation respectifs permet très certainement de réduire la perte de charge à ce niveau pour la concentrer uniquement au niveau de la chambre de tourbillonnement 36. En tout cas, il a été constaté que cette tête de distribution T avec plusieurs conduits d'alimentation distincts permet de réduire considérablement la raideur du ressort de précompression 69, sans détériorer la qualité du spray à la sortie de l'orifice de distribution 43. Il est possible que la qualité du spray soit également partiellement dépendante de la section de passage des canaux d'alimentation 15, qui est de l'ordre de 0,3 à 0,7 mm2 chacun.In a conventional precompression pump, the return spring 68 has a stiffness of the order of 1.52 N / mm (155 g / mm). As for the precompression spring, it generally has a stiffness of the order of 6.17 N / mm (629 g / mm). However, it has been empirically discovered that it is possible to significantly reduce the stiffness of the precompression spring 69, without deteriorating the quality of the spray at the dispensing head T according to the invention. The stiffness of the pre-compression spring acts directly on the resistance to actuation: by reducing the stiffness of the spring, the actuation of the pump is softer or softer. A stiffness of the order of 2 N / mm is sufficient to maintain a good quality spray. Very conclusive tests were carried out with a precompression spring whose stiffness is 2.03 N / mm (207 g / mm). However, it is even possible to lower the stiffness of the precompression spring 69 to about 1 N / mm, while maintaining an acceptable spray quality. With a stiffness of the order of 2 N / mm, the actuating force required to actuate the dispensing head T is of the order of 1.5 kg plus or minus 200 g. Reducing the stiffness of the precompression spring 69 while maintaining an acceptable spray quality can be explained by the fact that there are several supply ducts 15 which directly connect the inlet well 14 to the mounting housing 2 in which is engaged the nozzle 4. Preferably, there are two supply ducts 15 which each connect a swirl channel 35 via a connecting section 34 formed between the pin 3 and the nozzle 4, as explained above. The symmetry of supply of the swirling channels by respective supply ducts certainly makes it possible to reduce the pressure drop at this level to concentrate it only at the swirl chamber 36. this dispensing head T with several separate supply lines considerably reduces the stiffness of the precompression spring 69, without deteriorating the quality of the spray at the outlet of the dispensing orifice 43. It is possible that the quality of the spray is also partially dependent on the passage section of the supply channels 15, which is of the order of 0.3 to 0.7 mm 2 each.

Sur la figure 7, la tête de distribution T est conforme aux variantes des figures 5 ou 6, dans lesquelles les conduits d'alimentation 15 sont situés en partie haute du noyau 3.On the figure 7 , the dispensing head T conforms to the variants of the Figures 5 or 6 , in which the supply ducts 15 are located in the upper part of the core 3.

En résumé, avec une symétrie d'alimentation du gicleur et une raideur de ressort de précompression de l'ordre de 1 à 3 N/mm, on obtient un dispositif de distribution dont l'actionnement est très doux ou souple, et dont le spray est pourtant de très bonne qualité.In summary, with a feed symmetry of the nozzle and a precompression spring stiffness of the order of 1 to 3 N / mm, there is obtained a dispensing device whose actuation is very soft or flexible, and whose spray is however of very good quality.
