La présente invention se rapporte à une valve de distribution d'un produit destinée à équiper un distributeur comprenant un récipient, apte à contenir le produit stocké sous pression sous l'action d'un gaz propulseur. L'invention se rapporte également à un distributeur équipé d'une telle valve. Ce distributeur est destiné, plus particulièrement, au conditionnement et à la distribution d'un produit fluide, tel qu'un produit cosmétique, dermatologique, ménager, alimentaire ou un produit d'atelier, tel que par exemple une laque capillaire, un spray désinfectant, une peinture ou un produit de nettoyage.The present invention relates to a valve for dispensing a product. intended to equip a dispenser comprising a container, capable of containing the product stored under pressure under the action of a propellant gas. The invention is also relates to a distributor equipped with such a valve. This distributor is intended, more particularly, for the packaging and distribution of a fluid product, such as a cosmetic, dermatological, household product, food or a workshop product, such as for example a hairspray, disinfectant spray, paint or cleaning product.
La valve de l'invention équipant ce distributeur est du type qui comprend une tige de manoeuvre disposée axialement dans un corps de valve. La tige de manoeuvre présente un passage pour le produit à distribuer. La valve comprend des moyens d'étanchéité, aptes à fermer ledit passage, la tige de manoeuvre pouvant être déplacée élastiquement par basculement latéral de la tige, dans le corps de valve entre une première position d'obturation du passage, où la tige est en position axiale, dans laquelle le passage est isolé du produit sous pression par les moyens d'étanchéité, et une deuxième position d'ouverture où la tige est inclinée par rapport à l'axe du corps de valve, seconde position dans laquelle ledit passage est en communication avec le produit sous pression, pour permettre la distribution du produit. La valve comprend en outre des moyens élastiques de rappel non métalliques, sollicitant la tige dans ladite première position. Par ailleurs, l'ouverture de la valve peut être provoquée également, par enfoncement axial, ce qui est intéressant pour le remplissage du récipient sur une chaíne de conditionnement.The valve of the invention fitted to this dispenser is of the type which includes a operating rod arranged axially in a valve body. The rod maneuver presents a passage for the product to be dispensed. The valve comprises sealing means, capable of closing said passage, the rod maneuver which can be resiliently displaced by lateral tilting of the rod, in the valve body between a first position for closing the passage, where the rod is in the axial position, in which the passage is isolated of the product under pressure by the sealing means, and a second open position where the rod is inclined relative to the axis of the body valve, second position in which said passage is in communication with the product under pressure, to allow the distribution of the product. The valve further comprises elastic non-metallic return means, biasing the rod in said first position. Furthermore, the opening of the valve can also be caused, by axial depression, which is interesting for filling the container on a chain of conditioning.
On connaít, par exemple, par le document FR-A-2 161 350, une valve comprenant une tige de manoeuvre disposée dans un corps de valve formé par un matériau élastomérique. L'actionnement de cette valve est effectué par enfoncement axial de la tige de manoeuvre à l'encontre de moyens de rappel élastique. Ces moyens sont constitués par une partie du corps de valve, en appui contre la tige. La valve, selon FR-A-2 161 350, est conçue pour être actionnée par enfoncement axial de la tige.We know, for example, from document FR-A-2 161 350, a valve comprising an operating rod arranged in a valve body formed by an elastomeric material. The actuation of this valve is carried out by axial depression of the operating rod against means of elastic reminder. These means consist of a part of the body of valve, pressing against the rod. The valve, according to FR-A-2 161 350, is designed to be actuated by axial depression of the rod.
On connaít, en outre, une valve actionnable par basculement latéral de la tige de manoeuvre, Ainsi, le document US-A-3 627 179 décrit une valve à basculement comprenant une tige munie d'une couronne d'étanchéité et sollicitée par des moyens de rappel élastiques. La couronne est en contact étanche avec un joint annulaire rapporté en élastomère. Une coupelle métallique est prévue pour assembler le joint sur un corps de valve. Les moyens de rappel élastique sont assurés par un fond du corps de valve, de faible épaisseur de sorte que, lors du basculement latéral de la tige, la couronne déforme élastiquement ce fond.We know, in addition, a valve actuable by lateral tilting of the rod maneuver, Thus, document US-A-3,627,179 describes a valve with tilting comprising a rod provided with a sealing ring and solicited by elastic return means. The crown is in contact waterproof with an elastomeric ring seal. A cup metal is provided to assemble the seal on a valve body. The elastic return means are provided by a bottom of the valve body, thin so that, during lateral tilting of the rod, the crown elastically deforms this background.
Cette valve présente les inconvénients suivants : lors d'actionnements répétés de la valve, le fond risque de se rompre et, ce qui provoquera, par la suite, la dispersion incontrôlée du contenu entier dans l'atmosphère. En outre, la force d'actionnement nécessaire pour la distribution du produit n'est pas constante. En effet, dû à la variation de la pression interne du distributeur, cette force d'actionnement est variable également.This valve has the following drawbacks: during actuations valve repeatedly, the bottom may rupture and, which will cause, by as a result, the uncontrolled dispersion of the entire contents in the atmosphere. In in addition, the actuating force necessary for the distribution of the product is not not constant. Indeed, due to the variation of the internal pressure of the distributor, this actuating force is also variable.
La présente invention vise à remédier aux inconvénients des valves de l'art antérieur, et a, en conséquence, pour objet une valve de construction simple et facile à fixer sur tout type de récipient sous pression. De plus, le prix de revient de cette valve est particulièrement avantageux. Avantageusement, la valve selon l'invention ne comporte aucune pièce métallique.The present invention aims to remedy the drawbacks of valves of the art anterior, and therefore relates to a valve of simple construction and easy to attach to any type of pressure vessel. In addition, the price of returns from this valve is particularly advantageous. Advantageously, the valve according to the invention has no metal parts.
Ainsi, l'invention, se rapporte à une valve de distribution, réalisée entièrement
en matière polymérique, comportant:
En particulier, selon un premier mode de réalisation, la tige présente à l'intérieur du canal de sortie, une portion annulaire formant saillie par rapport au reste de la tige, et dont une section transversale est de forme sphérique, présentant un centre géométrique, le canal de sortie ayant une portion, formant un renfoncement de forme complémentaire à celle de la portion formant saillie, et apte à recevoir, de manière étanche, ladite portion formant saillie, le point d'articulation de la tige coïncidant sensiblement avec le centre géométrique.In particular, according to a first embodiment, the rod has at inside the outlet channel, an annular portion projecting from to the rest of the stem, and whose cross section is spherical, having a geometric center, the outlet channel having a portion, forming a recess of a shape complementary to that of the portion projecting, and adapted to receive, in a sealed manner, said portion forming protrusion, the point of articulation of the rod substantially coinciding with the center geometric.
Selon une forme avantageuse de réalisation, la portion annulaire formant saillie présente un diamètre externe d'environ 4 mm à 7 mm, le reste de la tige ayant un diamètre compris entre 3 mm et 4 mm.According to an advantageous embodiment, the annular portion forming projection has an external diameter of about 4 mm to 7 mm, the rest of the rod having a diameter between 3 mm and 4 mm.
Lorsque ledit renfoncement complémentaire pratiqué dans le canal de sortie est soumis à aucune contrainte élastique, celui-ci présente un rayon de courbure inférieur d'environ 10% à environ 30% au rayon de courbure de la portion formant saillie. Ainsi, on obtient un serrage étanche de la tige dans le corps de valve, et ceci quelle que soit la position de basculement de la tige. When said additional recess made in the outlet channel is subjected to no elastic stress, this one has a radius of curvature about 10% to about 30% less than the radius of curvature of the protruding portion. Thus, a tight tightening of the rod is obtained in the valve body, regardless of the tilting position of the stem.
Selon un second mode de réalisation, la tige présente à l'intérieur du canal de sortie, une portion formant un évidement sous forme d'une gorge annulaire en forme de portion de tore, présentant un centre géométrique, le canal de sortie ayant une portion formant saillie, de forme complémentaire à celle de l'évidement, et apte à recevoir, de manière étanche, ladite gorge annulaire, le point d'articulation de la tige coïncidant avec le centre géométrique du tore. Avantageusement, lorsque ladite portion formant saillie est soumis à aucune contrainte élastique, celle-ci présente un rayon de courbure inférieur d'environ 10% à environ 30% au rayon de courbure de la portion formant un évidement. Dans ce cas, également, il se produit un serrage étanche de la tige dans le canal de sorte du corps de valve.According to a second embodiment, the rod present inside the channel of outlet, a portion forming a recess in the form of an annular groove in the shape of a torus portion, having a geometric center, the channel of outlet having a protruding portion, of shape complementary to that of the recess, and capable of receiving, in a sealed manner, said annular groove, the articulation point of the rod coinciding with the geometric center of the torus. Advantageously, when said protruding portion is subjected to no elastic stress, this has a smaller radius of curvature from about 10% to about 30% at the radius of curvature of the portion forming a obviously. In this case, too, there is a tight tightening of the rod in the outlet channel of the valve body.
Selon un aspect intéressant de l'invention, les moyens pour sélectivement, mettre en communication, l'extrémité de la tige débouchant dans le corps de valve, avec la chambre interne, comprennent une couronne d'étanchéité, sollicitée par des moyens de rappel élastiques, en appui de façon étanche sur un siège annulaire formé par ledit corps.According to an interesting aspect of the invention, the means for selectively, put in communication, the end of the rod opening into the body of valve, with the internal chamber, include a sealing ring, biased by elastic return means, in leaktight support on an annular seat formed by said body.
Pour faciliter le basculement latéral de la tige dans le canal de sortie du corps de valve, avantageusement, la distance selon l'axe de la tige entre le point d'articulation et le siège annulaire est comprise entre 3 mm et 4 mm. Pour les mêmes raisons, le corps de valve peut présenter, entre le point d'articulation et le siège, une portion tronconique, dont un plus petit diamètre est orienté vers le point d'articulation.To facilitate lateral tilting of the rod in the body outlet channel of valve, advantageously, the distance along the axis of the rod between the point articulation and the annular seat is between 3 mm and 4 mm. For the same reasons, the valve body may present, between the point of articulation and the seat, a frustoconical portion, of which a smaller diameter is oriented towards the point of articulation.
Quant à la réalisation de la tige et de la couronne d'étanchéité, elles sont réalisées, de préférence en une seule pièce, et sont constituées en un matériau thermoplastique rigide, tel que du polypropylène.As for the realization of the rod and the sealing crown, they are made, preferably in one piece, and are made up of a rigid thermoplastic material, such as polypropylene.
En particulier, la couronne d'étanchéité qui est avantageusement solidaire de la tige, est logée dans la chambre de valve et sollicitée en compression par les moyens élastiques de rappel sur le siège annulaire du corps, entourant la tige. Ainsi, lorsque la tige de manoeuvre est au repos, le siège annulaire assure, d'une part une étanchéité parfaite entre la paroi externe de la tige et la chambre de valve, et d'autre part, la couronne isole, en position de fermeture de la valve, la chambre de valve du canal de sortie de la tige. Avantageusement, la couronne d'étanchéité est cylindrique. Lorsque la tige de manoeuvre est actionnée à l'encontre des moyens de rappel, par basculement latéral, la couronne s'écarte partiellement du siège annulaire, et une communication est établie entre la chambre de valve et l'extérieur, permettant la distribution du produit sous pression.In particular, the sealing ring which is advantageously integral with the rod, is housed in the valve chamber and stressed in compression by the elastic return means on the annular seat of the body, surrounding the rod. Thus, when the operating rod is at rest, the annular seat ensures, on the one hand, a perfect seal between the external wall of the rod and the valve chamber, and on the other hand, the crown insulates, in the position of valve closure, the valve chamber of the rod outlet channel. Advantageously, the sealing ring is cylindrical. When the rod maneuver is actuated against the return means, by lateral tilting, the crown deviates partially from the annular seat, and communication is established between the valve chamber and the outside, allowing the distribution of the product under pressure.
Pour assurer la mobilité de la couronne d'étanchéité dans la chambre interne, celle-ci peut présenter, entre le siège et l'orifice d'entrée, une portion tronconique dont un plus petit diamètre est orienté vers l'orifice d'entrée. Cette portion tronconique facilite, notamment, le basculement de la tige de manoeuvre. To ensure the mobility of the sealing ring in the internal chamber, this may have, between the seat and the inlet, a portion frustoconical with a smaller diameter oriented towards the inlet orifice. This frustoconical portion facilitates, in particular, the tilting of the rod maneuver.
Avantageusement, le canal de distribution de la tige débouche dans le corps de valve par l'intermédiaire d'un passage traversant la tige radialement, à proximité de la couronne d'étanchéité.Advantageously, the rod distribution channel opens into the body valve through a passage through the rod radially, at near the sealing ring.
Pour la réalisation des moyens de rappel élastiques, on a prévu deux possibilités. Selon une première possibilité, les moyens de rappel élastique sont constitués par un ou plusieurs plots élastomériques portés par une paroi de la chambre et solidaire de celle-ci, ce (ou ces) plot(s) étant en appui élastique contre une partie portant la couronne. Avantageusement, le (ou les) plot(s) est (ou sont) venu(s) de matière avec le corps de valve. Notamment, lorsque la chambre de valve comporte un fond constitué d'une portion tronconique, ce (ou ces) plot(s) est (ou sont) disposé(s) sur cette portion tronconique. Avantageusement, le nombre de plots est de 4 ou 6. Ces plots sont, de préférence, de faible dimension par rapport à la chambre, par exemple d'une hauteur de l'ordre de 0,5 mm à 3 mm. Selon une seconde possibilité, le (ou les) plot(s) est (ou sont) porté(s) par une partie portant la couronne et disposé(s) sur la face opposée à la zone d'étanchéité, en appui élastique contre une paroi de la chambre.For the production of elastic return means, two arrangements have been made. possibilities. According to a first possibility, the elastic return means consist of one or more elastomeric studs carried by a wall of the chamber and integral with it, this (or these) stud (s) being in support elastic against a part carrying the crown. Advantageously, the (or the) stud (s) has (or have) come (s) of matter with the valve body. Especially, when the valve chamber has a bottom consisting of a portion frustoconical, this (or these) stud (s) is (or are) arranged (s) on this portion tapered. Advantageously, the number of pads is 4 or 6. These pads are preferably small in relation to the chamber, for example of a height of the order of 0.5 mm to 3 mm. According to a second possibility, the stud (s) is (or are) carried by a party carrying the crown and arranged on the face opposite to the sealing zone, bearing elastic against a wall of the chamber.
Pour la réalisation du corps de valve, on peut prévoir tout matériau élastomérique présentant une dureté Shore A comprise entre 30 et 70.Any material for the valve body can be provided elastomeric with a Shore A hardness between 30 and 70.
Ainsi, on confère au corps de valve à la fois suffisamment d'élasticité pour pouvoir y monter la tige de manoeuvre et suffisamment de rigidité pour assurer sa stabilité de forme. En outre, lorsque les moyens de rappel sont réalisés sous forme de plots portés par une des parois délimitant la chambre interne, ces plots peuvent être déformés par écrasement, lors de l'actionnement de la valve.Thus, the valve body is given both sufficient elasticity to ability to mount the operating rod and sufficient rigidity to ensure its shape stability. In addition, when the return means are made in the form of studs carried by one of the walls delimiting the chamber internally, these pads can be deformed by crushing, during actuation of the valve.
La valve de l'invention est destinée à équiper un distributeur d'un produit liquide. Elle est conçue plus particulièrement pour être montée sur le col d'un récipient rempli du produit et mis sous pression à l'aide d'un gaz propulseur.The valve of the invention is intended to equip a dispenser with a product liquid. It is designed more particularly to be mounted on the neck of a container filled with product and pressurized with a propellant.
Selon un mode de réalisation particulier de l'invention, ce distributeur est exempt de coupelle métallique, habituellement utilisée pour la fixation d'une valve sur un récipient, et la valve est montée directement sur le col du récipient. Dans ce cas, le col est conformé de sorte qu'il puisse coopérer avec les moyens d'encliquetage de la valve.According to a particular embodiment of the invention, this dispenser is free of metal cup, usually used for fixing a valve on a container, and the valve is mounted directly on the neck of the container. In this case, the neck is shaped so that it can cooperate with the latching means of the valve.
Grâce aux moyens d'encliquetage mentionnés ci-dessus l'assemblage du corps de valve sur le récipient peut ainsi être effectué sans avoir besoin de recours à une coupelle classique, car l'élasticité du matériau constitutif du corps de valve assure, d'une part la déformation nécessaire au montage de celui-ci sur le récipient, et d'autre part, une étanchéité suffisante pour résister à la pression interne du récipient. Thanks to the latching means mentioned above, the assembly of the valve body on the container can thus be performed without the need for use of a conventional cup, because the elasticity of the material of the valve body provides, on the one hand the deformation necessary for mounting this on the container, and on the other hand, a sufficient seal to resist to the internal pressure of the container.
Ainsi, la valve conforme à l'invention est de construction simple et ne comporte qu'un nombre de constituants réduit. En effet, elle ne comporte qu'une tige de manoeuvre et un corps de valve qui sont faciles à assembler. En outre, cette valve ne comporte aucune pièce constitutive en métal, susceptible de venir au contact avec le produit à distribuer, risquant, le cas échéant, de dégrader ce produit.Thus, the valve according to the invention is of simple construction and does not contains only a reduced number of constituents. Indeed, it does not include an easy-to-assemble operating rod and valve body. In addition, this valve does not have any metal component, likely to come into contact with the product to be distributed, risking, if necessary degrade this product.
Selon un mode de réalisation intéressant de l'invention, le corps de valve comporte, en outre, des moyens d'encliquetage extérieurs aptes à coopérer avec un orifice d'un récipient de produit liquide sur lequel est montée ladite valve en vue de la distribution dudit produit. De façon avantageuse, ces moyens d'encliquetage sont constitués par une gorge annulaire pratiquée dans la paroi externe du corps de valve.According to an interesting embodiment of the invention, the valve body further comprises external latching means capable of cooperating with an orifice of a container of liquid product on which is mounted said valve for the distribution of said product. Advantageously, these latching means consist of an annular groove made in the outer wall of the valve body.
Le récipient utilisable pour le montage de cette valve peut être choisi parmi les récipients en aluminium, en fer blanc ou en matière plastique. A cet effet, le récipient comporte une extrémité ouverte (ou orifice) apte à coopérer avec les moyens d'encliquetage du corps de valve.The container which can be used for mounting this valve can be chosen from aluminum, tin or plastic containers. To this end, the container has an open end (or orifice) capable of cooperating with the latching means of the valve body.
Ainsi, la valve de l'invention peut être montée sur un tel récipient par une simple opération d'enfoncement, et ne nécessite pas, en outre, de pièces intermédiaires ou de joints d'étanchéité. Un autre avantage réside dans le fait que les récipients susceptibles d'être assemblés avec la valve de l'invention peuvent être choisis parmi les récipients simples et donc économiquement avantageux. A cet effet, l'orifice du récipient dans lequel le corps de valve doit être monté, peut présenter, notamment, des tolérances relativement larges et le montage de la valve sur le récipient ne nécessite pas de façonnage particulier et, en conséquence coûteux.Thus, the valve of the invention can be mounted on such a container by a simple digging operation, and does not further require parts intermediates or gaskets. Another advantage is that that the receptacles capable of being assembled with the valve of the invention can be chosen from simple containers and therefore economically advantageous. For this purpose, the orifice of the container in which the valve body must be mounted, may have, in particular, relatively wide tolerances and mounting the valve on the container does not require shaping particular and therefore expensive.
Pour mieux faire comprendre la présente invention, on va décrire maintenant, à titre d'exemples purement illustratifs et nullement limitatifs, plusieurs modes de réalisation de l'invention, comme représenté sur les dessins annexés. Sur ces dessins :
- la figure 1 représente une coupe axiale d'un premier mode de réalisation d'une valve conforme à l'invention, en position fermée ;
- la figure 2 représente une coupe axiale de la valve de la figure 1, en position ouverte ;
- la figure 3 représente une coupe axiale d'un second mode de réalisation de la valve conforme à l'invention ;
- la figure 4 représente une coupe axiale partielle d'un récipient équipé de la valve de la figure 1, et exempt d'une coupelle porte-valve.
- Figure 1 shows an axial section of a first embodiment of a valve according to the invention, in the closed position;
- 2 shows an axial section of the valve of Figure 1, in the open position;
- Figure 3 shows an axial section of a second embodiment of the valve according to the invention;
- 4 shows a partial axial section of a container equipped with the valve of Figure 1, and free of a valve holder cup.
La valve 1 conforme. à l'invention, représentée sur les figures 1 et 2,
respectivement en position de fermeture et d'ouverture, est destinée à
équiper un distributeur contenant un produit liquide, telle qu'une laque
capillaire par exemple, mis sous pression par l'action d'un gaz propulseur.
Comme visible, notamment à la figure 1, la valve 1 comporte un corps 2
ayant une forme générale en tronc de cône d'axe de révolution A, et une tige
de manoeuvre 3, de forme généralement cylindrique, pourvue d'un axe X. En
position de repos de la valve, les axes A et X sont confondus. La tige 3 est
réalisée en un matériau thermoplastique rigide.
Selon l'invention, le corps de valve 2 est réalisé en un matériau élastiquement
déformable, par exemple un élastomère de caoutchouc de nitrile, dont la
dureté Shore A est comprise dans la gamme comprise entre 30 et 70. Le
corps comporte une grande base 2a et une petite base 2b, reliées par une
partie tronconique 2c et une partie cylindrique 2d.According to the invention, the
A l'intérieur du corps de valve 2 est ménagée une chambre interne 4 de
section circulaire, délimitée par des parois périphériques 4a, 4b, 4c, 4d. La
paroi 4a est de forme cylindrique et est raccordée à une portion tronconique
4b dont le sommet s'ouvre vers l'extérieur de la chambre de valve par un
canal axial d'admission 5.Inside the
Le canal axial d'admission 5, destiné à l'admission du produit à distribuer, est
pratiqué au centre de la petite base 2b et débouche dans la chambre 4. Ce
canal d'admission 5 est relié à un tube plongeur 6 dont l'extrémité libre (non
représentée) plonge en permanence dans le produit. Ce produit est
conditionné dans un récipient équipé de la valve 1 (voir figure 4).The
Du côté opposé au canal d'admission 5, la paroi cylindrique 4a est raccordée à
une zone annulaire d'étanchéité 4c située dans un plan perpendiculaire à l'axe
A. La zone annulaire 4c se prolonge vers le haut par une seconde portion
tronconique 4d, facilitant le basculement de la tige 3. Le sommet de la portion
tronconique 4d débouche dans un renfoncement 8 de forme sensiblement
sphérique. Ce renfoncement 8 fait partie d'un canal de sortie 10 qui est disposé
dans le prolongement du canal d'admission 5, le canal 10 conduisant, depuis la
chambre interne 4, vers l'extérieur. Le canal de sortie 10 est traversé par la tige
3, la paroi externe de la tige 3 étant en contact d'étanchéité parfaite contre la
paroi délimitant le canal de sortie 10. Sensiblement à mi-hauteur du canal de
sortie 10, la tige 3 présente une portion annulaire 14 formant saillie par rapport
au reste de la tige, et dont la section transversale, axiale est de forme
sphérique, de forme complémentaire à la forme du renfoncement 8. Une
extrémité libre 11 du canal de sortie 10 comporte un alésage conique, tandis
que l'autre extrémité 13 du canal de sortie forme la portion tronconique 4c
précitée.On the side opposite to the
La tige 3 comporte un canal central de distribution 12 traversant la tige depuis
l'extrémité émergente 3b jusqu'à une hauteur située sensiblement à la hauteur
de la zone annulaire 4c. A cette hauteur, le canal central 12 se termine par un
passage radial 15 traversant la tige radialement et aboutissant dans la partie
supérieure de la chambre 4. La partie terminale 3a de la tige est conformée en
tronc de cône 3c comportant une grande 16 et une petite 17 bases reliées par
une partie tronconique 18. La grande base 16 porte une couronne périphérique
19 en appui élastique étanche contre la zone annulaire 4c, qui constitue alors
un siège. En pratique, la couronne présente radialement une faible épaisseur
d1 (environ 0,1 à 0,5 mm, voir figure 2). L'appui élastique de la couronne 19
contre le siège 4c est assuré par plusieurs plots 20, repartis régulièrement sur
la paroi tronconique 4b de la chambre 4 et en appui élastique contre la partie
tronconique 18 de la tige 3. Ainsi, le bord libre de la couronne 19 rentre de
quelques 10èmes de mm dans le siège 4c et crée une étanchéité parfaite entre la
chambre de valve et le canal de distribution.The
Selon un autre mode de réalisation, les plots 20 peuvent être réalisés sur le
tronc de cône 3c de la tige et moulés intégralement avec cette dernière. Ces
plots sont en appui élastique contre la paroi tronconique 4b. Ainsi, lors de
l'actionnement de la valve par basculement de la tige 3, les plots rentrent en
partie dans la paroi 4b.According to another embodiment, the
La tige 3 (y compris le tronc de cône 3c) est réalisée en un matériau
thermoplastique relativement rigide comme le polypropylène. Son diamètre est
d'environ 3 mm à environ 4 mm, sa portion annulaire externe formant saillie 14
ayant un diamètre compris entre 4 mm et 7 mm. Dans ce cas, le renfoncement
complémentaire 8, lorsqu'il est soumis sous aucune contrainte élastique,
présente un diamètre interne inférieur d'environ 10% à 30% au diamètre
externe de la portion formant saillie 14. Avantageusement, le centre P de la
portion en saillie 14 se trouve à une hauteur axiale selon l'axe A, située de 3
mm à 4 mm du siège 4c.The rod 3 (including the
Une zone de transition du corps de valve, située entre la partie cylindrique 2d
et la partie tronconique 2c du corps 2, comporte des moyens d'encliquetage 7
sous forme d'une gorge annulaire de fixation dont le rôle sera expliqué lors de
la description de la figure 3.A transition zone of the valve body, located between the
Le fonctionnement de la valve 1 est schématisé sur la figure 2. Pour
provoquer l'ouverture de la valve 1, on provoque un pivotement de la tige 3
autour du point d'articulation P, en direction de la flèche B. lors de ce
pivotement, l'axe X de la tige est incliné par rapport à l'axe A du corps de
valve, l'angle α formé entre les deux axes étant de l'ordre de 2° à 10°. Lors
de ce pivotement, une partie 19a de la couronne 19 s'éloigne du siège 4c,
créant un écartement d2 . En même temps, le (ou les) plot(s) 20 qui se
trouve(nt) sur la paroi tronconique 4b, du côté opposé à l'écartement d2 , est
(sont) écrasé(s) par la partie tronconique 3c de la tige. Dans l'exemple de
réalisation considéré, quatre plots 20 de forme allongée ont été réalisés de
hauteur d'environ 1 mm, d'une largeur d'environ 1,5 mm et d'une longueur
d'environ 1,5 mm. Sous la poussée d'un gaz propulseur, le produit est alors
acheminé via le tube plongeur 6 et l'orifice d'entrée 5 dans la chambre 4, pour
arriver dans le canal de distribution 12 via l'écartement d2 et le passage radial
15. Lorsque cesse le pivotement, la distribution du produit s'arrête, car la
couronne 19 revient en contact étanche contre le siège 4c. Ainsi lors du
pivotement de la tige dans le canal de sortie, celle-ci reste en contact
annulaire étanche avec le canal, au niveau de tout ou partie de sa portion
sphérique 14.The operation of the
Sur la figure 3, on a représenté un second mode de réalisation d'une valve
conforme à l'invention portant dans son ensemble la référence 101. Cette
valve, représentée en position de repos, se distingue de la valve des figures
1 et 2 par le fait que la forme du profil de la portion annulaire de la tige, ainsi
que la forme du profil complémentaire du canal de sortie sont inversées. Les
parties de la valve 101 identiques ou jouant un rôle semblable aux parties de
la valve des figures 1 et 2, portent les mêmes références majorées de 100.
Leur description ne sera pas reprise que succinctement.In Figure 3, there is shown a second embodiment of a valve
according to the invention as a whole bearing the
Ainsi, la tige de valve 103 traverse le canal de sortie 110 qui relie la chambre
de valve 104 avec l'extérieur. La tige présente, à l'intérieur du canal de sortie,
sensiblement à mi-hauteur, une portion 114 formant un évidement sous forme
d'une gorge annulaire en forme de portion de tore, présentant un centre
géométrique P, le canal de sortie 110 ayant une portion 108 formant saillie,
de forme complémentaire à celle de l'évidement 114, et apte à recevoir de
manière étanche la gorge annulaire, le point d'articulation de la tige 103
coïncidant avec le centre géométrique P du tore.Thus, the
Le fonctionnement de la valve 103 est analogue au fonctionnement de la
valve 1.The operation of the
Sur la figure 4, on voit la valve conforme aux figures 1 et 2, montée sur un
récipient 202 sans coupelle porte-valve. Ce récipient est un flacon en
aluminium, notamment monobloc, ou en un matériau plastique rigide tel que
du polyéthylène téréphthalate (PET). Le récipient 202 comporte un col 204
dont l'extrémité ouverte est repliée d'équerre formant un plateau annulaire
206, pourvu d'un orifice circulaire 208.In Figure 4, we see the valve according to Figures 1 and 2, mounted on a
Dans l'orifice 208 est fixé le corps 2 de valve 1, par enfoncement de celui-ci,
de sorte que le plateau annulaire 206 vienne se loger dans la gorge annulaire
7 du corps 2 de valve. Du fait de l'élasticité du corps 2, l'enfoncement de ce
dernier dans l'orifice 208 peut être effectué par une opération simple. De
plus, lorsque l'orifice 208 présente des variations de diamètre, les tolérances
relativement grandes sont compensées par l'élasticité du corps de valve,
sans risques de fuite de gaz propulseur. Ce montage est particulièrement
avantageux, du point de vue économique.In the
