Description
La présente invention concerne un ensemble moulé d'une seule pièce pouvant être utilisé dans un distributeur de fluide, notamment un atomiseur de liquide à pompe manuelle. Ses atomiseurs comportent généralement un clapet de retenue qui est monté dans une chambre située juste en amont de l'orifice d'atomisation et dont le rôle est de bloquer le passage d'entrée de la chambre jusqu'à une pression prédéterminée et d'empêcher ensuite que le liquide sous pression sorte de la chambre par un passage autre que l'orifice d'atomisation. Ainsi, le brevet des E.-U.A no 3 685 739 décrit une valve comportant un obturateur libre mobile axialement dans la chambre de sortie de l'atomiseur. Sous l'effet d'une légère dépression qui suit le coup de pompe, l'obturateur vient fermer le passage d'alimentation de la chambre pour empêcher que de l'air soit aspiré dans la pompe par l'orifice d'atomisation. Au coup de pompe suivant, l'obturateur est déplacé en sens inverse par l'augmentation de la pression dans le passage d'alimentation et ne laisse passer le liquide que par les passages de tourbillonnement de l'orifice d'atomisation. The present invention relates to a molded assembly in one piece which can be used in a fluid distributor, in particular a liquid atomizer with manual pump. Its atomizers generally include a check valve which is mounted in a chamber located just upstream of the atomization orifice and whose role is to block the entry passage of the chamber to a predetermined pressure and to prevent then that the pressurized liquid leaves the chamber through a passage other than the atomization orifice. Thus, U.S. Patent No. 3,685,739 describes a valve having a free shutter movable axially in the outlet chamber of the atomizer. Under the effect of a slight depression which follows the stroke of the pump, the shutter closes the supply passage of the chamber to prevent air from being sucked into the pump through the atomization orifice. At the next pump stroke, the shutter is moved in the opposite direction by increasing the pressure in the supply passage and lets the liquid pass only through the swirling passages of the atomization orifice.
Le brevet des E.-U.A. no 3 061 202 au nom de Tyler décrit une valve analogue, mais dont l'obturateur est associé à un ressort qui le maintient fermé tant que la pression du liquide en amont de la chambre ne dépasse pas une certaine valeur. Dans les deux cas, le liquide passe ensuite dans une chambre d'atomisation d'où il est éjecté par un orifice de forme appropriée. Dans ce brevet, le passage d'alimentation est fermé par un clapet conique, mais rien n'empêche d'utiliser un clapet plat. La présente invention se propose d'améliorer la valve du brevet Tyler en remplaçant la plaque de fermeture de la chambre d'atomisation, le ressort et le clapet par un ensemble moulé d'une seule pièce qui assure essentiellement les mêmes fonctions. Les avantages qui en découlent sont nombreux: petit nombre de pièces, simplicité d'assemblage, réduction des coûts, meilleure fiabilité et suppression des problèmes d'incompatibilité, notamment de corrosion des pièces métalliques. The US patent No. 3,061,202 in the name of Tyler describes a similar valve, but the shutter of which is associated with a spring which keeps it closed as long as the pressure of the liquid upstream of the chamber does not exceed a certain value. In both cases, the liquid then passes into an atomization chamber from which it is ejected through an orifice of suitable shape. In this patent, the feed passage is closed by a conical valve, but nothing prevents the use of a flat valve. The present invention proposes to improve the valve of the Tyler patent by replacing the closure plate of the atomization chamber, the spring and the valve by a molded assembly in one piece which essentially performs the same functions. The resulting advantages are numerous: small number of parts, simplicity of assembly, cost reduction, better reliability and elimination of incompatibility problems, in particular corrosion of metal parts.
Un autre brevet au nom de MacGuire-Cooper (brevet des E.-U.A. no 3 620 421) décrit une valve dont l'obturateur est ouvert par un mouvement de basculement latéral qui le décolle de son siège pour permettre l'écoulement d'un produit contenu dans un récipient sous la valve. L'obturateur est rappelé vers sa position fermée par une partie annulaire élastique qui est moulée avec le reste de l'obturateur. L'ensemble moulé selon l'invention est défini par la revendication 1. Le ressort sinueux a de préférence la forme d'un S. La technique de moulage utilisée assure une parfaite panéité de la face active de l'élément inducteur de tourbillon. Another patent in the name of MacGuire-Cooper (US Patent No. 3,620,421) describes a valve, the valve of which is opened by a lateral tilting movement which takes it off its seat to allow the flow of a product contained in a container under the valve. The shutter is returned to its closed position by an elastic annular part which is molded with the rest of the shutter. The molded assembly according to the invention is defined by claim 1. The sinuous spring preferably has the shape of an S. The molding technique used ensures perfect panicity of the active face of the vortex-inducing element.
Les dessins annexés représentent à titre d'exemple non limitatif un mode de réalisation de l'objet de l'invention. The accompanying drawings show by way of nonlimiting example an embodiment of the subject of the invention.
La figure 1 est une coupe axiale partielle de la tête d'un atomiseur dont la valve est représentée en position de repos. Figure 1 is a partial axial section of the head of an atomizer whose valve is shown in the rest position.
La figure 2 est une coupe semblable à celle de la figure 1 montrant la valve en position d'atomisation et illustrant une configuration différente des passages du dispositif inducteur de tourbillon. Figure 2 is a section similar to that of Figure 1 showing the valve in the atomizing position and illustrating a different configuration of the passages of the whirlpool inducing device.
La figure 3 est une coupe dans le plan 3-3 de la figure 1 montrant la face avant de l'élément inducteur de tourbillon et ses passages tangentiels. Figure 3 is a section in plane 3-3 of Figure 1 showing the front face of the vortex-inducing element and its tangential passages.
La figure 4 est une coupe dans le plan 4-4 de la figure 2 montrant les passages tangentiels formés dans la paroi avant de la chambre d'atomisation. Figure 4 is a section in plane 4-4 of Figure 2 showing the tangential passages formed in the front wall of the atomization chamber.
La figure 1 représente la partie supérieure d'un atomiseur à pompe dont le corps 10 comporte un alésage cylindrique 11 servant le logement à une pièce rapportée 12 qui est emmanchée à force de manière étanche. La pièce 12 est un bouchon creux dont le fond est percé d'un orifice 13 communiquant avec une chambre intérieure 14. L'extrémité ouverte de la chambre 14 (à droite sur la figure 1) communique avec un passage axial 15 qui est entouré d'un épaulement annulaire 16. La chambre 14 contient un ensemble monobloc 17 qui est mis en place avant l'emmanchement du bouchon 12. L'ensemble 17 comprend un ressort en S 17a, un clapet circulaire 17b et un élément inducteur de tourbillon 17c moulés ensemble. A l'origine, l'ensemble 17 est un peu plus long que la chambre 14 de façon que le ressort 17a soit légèrement comprimé entre les deux extrémités de la chambre lorsque le bouchon 12 est introduit à fond dans le corps 10. FIG. 1 shows the upper part of a pump atomizer, the body 10 of which has a cylindrical bore 11 serving to accommodate an insert 12 which is force-fitted in a leaktight manner. The part 12 is a hollow plug, the bottom of which is pierced with an orifice 13 communicating with an interior chamber 14. The open end of the chamber 14 (on the right in FIG. 1) communicates with an axial passage 15 which is surrounded by 'an annular shoulder 16. The chamber 14 contains a monobloc assembly 17 which is put in place before the plug 12 is fitted. The assembly 17 comprises an S-shaped spring 17a, a circular valve 17b and a molded vortex inductor 17c together. Originally, the assembly 17 is a little longer than the chamber 14 so that the spring 17a is slightly compressed between the two ends of the chamber when the plug 12 is fully inserted into the body 10.
On peut voir sur la figure 1 que le ressort 17a, le clapet circulaire 17b et l'élément 17c, généralement un disque circulaire, sont reliés les uns aux autres par des tiges moulées 17d et 17e. L'élément 17c est de préférence moulé avec un étrier semi-circulaire 17f qui part de sa périphérie et dont le sommet est relié à la tige 17d, comme illustré sur les figures 1 et 2. It can be seen in Figure 1 that the spring 17a, the circular valve 17b and the element 17c, generally a circular disc, are connected to each other by molded rods 17d and 17e. The element 17c is preferably molded with a semi-circular stirrup 17f which starts from its periphery and the top of which is connected to the rod 17d, as illustrated in FIGS. 1 and 2.
Cette configuration permet d'assurer une bonne planéité de la face active (du côté de l'orifice 13) du disque 17c en évitant la formation d'une dépression due à un léger manque de matière au moment de l'injection. (Le cas se produit souvent lorsqu'on moule une pièce comportant une tige centrale qui se raccorde à un disque transversal). La planéité du disque 17c est importante pour assurer le bon fonctionnement du dispositif d'atomisation centrifuge décrit ci-après. On voit sur la figure 1 que le fond de la chambre 14 côté extérieur est plat autour de l'orifice 13, alors que le disque 17c comporte un ou plusieurs passages radiaux 18,19 formés dans sa face active. La figure 3 montre bien la configuration de ces passages qui se rejoignent tangentiellement dans une petite chambre centrale où se produit le tourbillon. Les passages 18 et 19 sont fermés lorsque le disque 17c est appliqué contre la paroi radiale lisse du bouchon 12. On notera cependant que le disque 17c a un diamètre plus petit que celui de la chambre 14 dans laquelle il est centré par trois ou plus de trois saillies radiales 17g. Ainsi, les entrées des deux passages 18 et 19 restent à égale distance de la paroi de la chambre et sont alimentées dans des conditions identiques. Le diamètre total du disque 17c avec ses saillies 17g est légèrement inférieur au diamètre intérieur du bouchon 12 pour que l'ensemble 17 soit libre longitudinalement. This configuration ensures good flatness of the active face (on the side of the orifice 13) of the disc 17c by avoiding the formation of a depression due to a slight lack of material at the time of injection. (The case often occurs when a part with a central rod which connects to a transverse disc is molded). The flatness of the disc 17c is important for ensuring the proper functioning of the centrifugal atomization device described below. We see in Figure 1 that the bottom of the chamber 14 outside side is flat around the orifice 13, while the disc 17c has one or more radial passages 18,19 formed in its active face. Figure 3 shows the configuration of these passages which meet tangentially in a small central chamber where the vortex occurs. The passages 18 and 19 are closed when the disc 17c is applied against the smooth radial wall of the plug 12. It will however be noted that the disc 17c has a smaller diameter than that of the chamber 14 in which it is centered by three or more three radial projections 17g. Thus, the inputs of the two passages 18 and 19 remain at an equal distance from the wall of the chamber and are supplied under identical conditions. The total diameter of the disc 17c with its projections 17g is slightly less than the inside diameter of the plug 12 so that the assembly 17 is free longitudinally.

laire 16 pour le clapet 17b qui obture normalement le passage 15 grâce à la légère précontrainte du ressort 17a. area 16 for the valve 17b which normally closes the passage 15 thanks to the slight prestressing of the spring 17a.
En variante, le disque 17c peut être lisse et des passages tangentiels 20,21, peuvent être formés dans la face intérieure du fond du bouchon 12, comme illustré sur les figures 2 et 4. La figure 4 montre comment ces passages permettent de créer un tourbillon centré sur l'axe de l'orifice d'atomisation 13. As a variant, the disc 17c can be smooth and tangential passages 20, 21 can be formed in the inner face of the bottom of the plug 12, as illustrated in FIGS. 2 and 4. FIG. 4 shows how these passages make it possible to create a vortex centered on the axis of the atomization orifice 13.
L'atomiseur de la figure 1 fonctionne de manière classique, c'est-à-dire que l'utilisateur exerce une pression intermittente sur le levier 22 pour pomper le liquide d'un récipient (non représenté) dans le passage 15 où il exerce une pression sur le clapet 17b. Lorsque cette pression est suffisante pour surmonter la précontrainte du resort 17a, le clapet 17b s'écarte vers la gauche de son siège annulaire 16 (figure 2) et laisse passer le liquide sous pression du passage 15 dans la chambre 14. Lorsque la chambre 14 est pleine, le liquide entre dans les passages 20,21 et arrive à l'orifice 13 avec un mouvement tourbillonnaire rapide qui est dû aux débits antiparallèles des deux passages. Le liquide est ensuite éjecté par l'orifice 13 où il est atomisé par l'action de la pression et de la force centrifuge. The atomizer of Figure 1 operates in a conventional manner, that is to say that the user exerts an intermittent pressure on the lever 22 to pump the liquid from a container (not shown) in the passage 15 where it exerts pressure on the valve 17b. When this pressure is sufficient to overcome the prestressing of the resort 17a, the valve 17b moves to the left of its annular seat 16 (FIG. 2) and lets the pressurized liquid pass from the passage 15 into the chamber 14. When the chamber 14 is full, the liquid enters the passages 20, 21 and arrives at the orifice 13 with a rapid vortex movement which is due to the antiparallel flows of the two passages. The liquid is then ejected through the orifice 13 where it is atomized by the action of pressure and centrifugal force.
Lorsque l'utilisateur cesse d'appuyer sur le levier 22, le retour de l'organe de pompage à sa position de repos crée une légère dépression dans le passage 15 et la pression atmosphérique normale régnant dans la chambre 14 s'ajoute à la force du ressort 17a pour ramener le clapet 17b contre son siège 16. When the user stops pressing on the lever 22, the return of the pumping member to its rest position creates a slight depression in the passage 15 and the normal atmospheric pressure prevailing in the chamber 14 adds to the force of the spring 17a to bring the valve 17b against its seat 16.
L'opération peut être répétée tant qu'il reste du liquide dans le récipient. The operation can be repeated as long as there is liquid remaining in the container.
Avec la première configuration des figures 1 et 3, le fonctionnement de l'appareil est le même, sauf que le liquide entre s dans les passages 18,19 du disque 17c au lieu des passages 20, 21 du bouchon 12. With the first configuration of FIGS. 1 and 3, the operation of the device is the same, except that the liquid enters the passages 18, 19 of the disc 17 c instead of the passages 20, 21 of the plug 12.
On notera que le disque 17c reste toujours plaqué contre le fond de la chambre 14 dans les deux modes de réalisation. It will be noted that the disc 17c always remains pressed against the bottom of the chamber 14 in the two embodiments.
Le ressort 17a a de préférence une forme en S, comme io illustré, mais on pourrait aussi adopter d'autres formes sinueuses: boucle simple, double S, hélice, etc., à condition de ne pas se coincer contre les parois de la chambre 14 au moment de la compression. La force du ressort 17a peut être changée au moment du moulage de l'ensemble 17 en faisant 15 varier certaines dimensions de l'empreinte du moule ou en utilisant divers matériaux plus ou moins élastiques ou résistants. Par exemple, pour affaiblir le ressort 17a, on peut jouer sur la largeur et/ou l'épaisseur de la languette de matière. The spring 17a preferably has an S shape, as illustrated, but other sinuous shapes could also be adopted: single loop, double S, helix, etc., provided that it does not get caught against the walls of the chamber. 14 at the time of compression. The force of the spring 17a can be changed during the molding of the assembly 17 by varying certain dimensions of the mold cavity or by using various more or less elastic or resistant materials. For example, to weaken the spring 17a, one can play on the width and / or the thickness of the tongue of material.
La matière plastique utilisée pour le moulage de l'ensemble 20 17 est de préférence un polypropylène ou un polyéthylène, mais on pourra choisir d'autres matières ayant les caractéristiques voulues sur le plan de la compatibilité avec les fluides à distribuer, de la stabilité dimensionnelle (pour éviter des variations excessives de la force du ressort, un coincement 25 dans la chambre 14 ou des déformations du disque 17c ou du clapet 17b), de l'élasticité nécessaire et évidemment des propriétés de moulage. The plastic material used for molding the assembly 17 is preferably polypropylene or polyethylene, but other materials having the desired characteristics can be chosen with regard to compatibility with the fluids to be dispensed, dimensional stability. (to avoid excessive variations in the force of the spring, a jamming 25 in the chamber 14 or deformations of the disc 17c or of the valve 17b), of the necessary elasticity and obviously of the molding properties.
