De même, lorsque le récipient est destiné à fonctionner tête en haut, un tube plongeur est monté sur le corps de valve, une des extrémités du corps de valve étant reliée au passage d'entrée du corps de valve, l'autre extrémité étant située sensiblement au fond du réservoir. La réalisation d'une telle PGA, de même que le montage d'un tube plongeur ne pose aucune difficulté dans l'hypothèse où le corps de valve est réalisé en un matériau rigide ou semi rigide, tel qu'un métal ou un plastique de type polypropylène.Typically, a valve consists of a valve body, having a inlet passage and an outlet passage, sealing means for, in response to an actuation command, switch the input passage communication with the outlet passage, and elastic return means to, in the absence of an actuation command, request the resources shutter in closed position. Such valves can be fitted with a additional gas outlet (PGA), in the form of an orifice in the valve body, and opening into the upper part of a container on which valve is mounted, which upper part contains gas used to pressurizing the liquid. The function of the PGA is to enrich the gas with distributed mixture, which may be desirable, especially when distribution of a product in the form of foam. Likewise, when the container is intended to operate head up, a dip tube is mounted on the body valve, one end of the valve body being connected to the passage valve body inlet, the other end being located substantially at the bottom of the tank. The realization of such a PGA, as well as the mounting of a tube plunger poses no difficulty in the event that the valve body is made of a rigid or semi-rigid material, such as metal or plastic polypropylene type.

Toutefois, il est connu, notamment du 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. Le tube plongeur est directement fixé sur le corps de valve en élastomère.However, it is known, in particular from document FR-A-2 161 350, a valve comprising an operating rod disposed in a valve body formed by an elastomeric material. The actuation of this valve is carried out by axial insertion of the operating rod against return means elastic. The dip tube is directly attached to the valve body in elastomer.

Une autre valve de ce type est décrite également dans le brevet DE-A-1 037 377. Selon ce document, les moyens d'obturation sont constitués d'une portion d'extrémité arrondie d'une tige de valve qui, lorsqu'elle est basculée, provoque la mise en communication du passage d'entrée avec le passage de sortie. Selon ce document, le tube plongeur est solidaire du bord libre délimité par le passage d'entrée du corps de valve. Selon un mode de réalisation particulier, le tube plongeur forme une seule et même pièce avec le corps de valve. L'expérience montre que le fait d'avoir le tube plongeur monté directement sur le corps de valve en matériau élastique n'est pas satisfaisant. Dans la pratique, en raison des pressions importantes régnant à l'intérieur du récipient, un accrochage suffisamment solide est difficile, voire impossible à réaliser. En outre, à l'ouverture de la valve, dans le cas d'un accrochage tel que décrit dans le document DE-A-1 037 377, le tube plongeur est soumis à des contraintes relativement importantes, qui risquent de l'endommager ou de le désolidariser du corps de valve. De plus, la réalisation d'un orifice dans le corps de valve élastique pour réaliser une PGA, est quasiment impossible du fait de la nature même du matériau. Dans un tel matériau, il faudrait en effet réaliser un orifice d'un diamètre relativement important pour avoir une PGA effective. Cet orifice de diamètre important serait toutefois préjudiciable à la distribution du produit.Another valve of this type is also described in patent DE-A-1 037 377. According to this document, the sealing means consist of a portion rounded end of a valve stem which, when tilted, causes the communication of the entry passage with the exit passage. According to this document, the dip tube is integral with the free edge delimited by the inlet passage of the valve body. According to a particular embodiment, the dip tube forms a single piece with the valve body. Experience shows that having the dip tube mounted directly on the valve body of elastic material is not satisfactory. In practice, due to the high pressures inside the container, a sufficiently strong attachment is difficult, if not impossible, to achieve. In in addition, when the valve is opened, in the event of an attachment as described in document DE-A-1 037 377, the dip tube is subjected to stresses relatively large, which may damage or dissociate it valve body. In addition, the creation of an orifice in the valve body elastic to achieve a PGA, is almost impossible due to the nature even material. In such a material, it would indeed be necessary to make an orifice of a relatively large diameter to have an effective PGA. This orifice large diameter would however be detrimental to the distribution of the product.

Du document US-A-3 618 832, il est connu de réaliser une valve en un matériau élastomérique, et comportant une tige de valve comportant une première portion émergeant à l'extérieur du récipient de manière à permettre la distribution du produit, et une seconde portion, opposée à la première, disposée dans le passage d'entrée du corps de valve, et émergeant à l'intérieur du récipient, au dessus de la surface du liquide. Une prise de gaz additionnelle est prévue sous forme d'un passage ménagé axialement entre la surface extérieure de la portion de tige disposée dans le passage d'entrée, et une portion correspondante du corps de valve élastomérique. Un des problèmes liés à une telle conception tient au fait que, le passage ainsi réalisé est au moins en partie délimité par le corps de valve en matériau élastomérique, lequel matériau est sujet notamment à des variations de souplesse ou à des gonflements qui vont modifier le débit de gaz additionnel entrant dans la valve. En outre, dans l'hypothèse où il n'est pas souhaitable d'avoir de prise de gaz additionnelle, lors de l'actionnement de la valve, il peut se produire une entrée indésirable de gaz entre ladite seconde portion de la tige de valve et la portion correspondante du corps de valve.From document US-A-3 618 832, it is known to produce a valve in one elastomeric material, and comprising a valve stem comprising a first portion emerging outside the container so as to allow distribution of the product, and a second portion, opposite the first, disposed in the inlet passage of the valve body, and emerging therein of the container, above the surface of the liquid. An additional gas intake is provided in the form of a passage axially arranged between the surface exterior of the rod portion disposed in the inlet passage, and a corresponding portion of the elastomeric valve body. One of the problems linked to such a conception is due to the fact that, the passage thus achieved is at less partially delimited by the valve body made of elastomeric material, which material is subject in particular to variations in flexibility or to swellings which will modify the additional gas flow entering the valve. In addition, in the event that it is not desirable to have a gas outlet additional, upon actuation of the valve, an entry may occur undesirable gas between said second portion of the valve stem and the portion valve body.

Aussi, est-ce un des objets de la présente invention que de fournir une valve ne présentant pas les inconvénients mentionnés en référence aux dispositifs conventionnels discutés précédemment.It is therefore one of the objects of the present invention to provide a valve which does not not having the drawbacks mentioned with reference to the devices previously discussed.

C'est en particulier un objet de l'invention que de fournir une valve permettant de contrôler de manière précise l'entrée éventuelle de gaz additionnel, et en particulier, d'empêcher toute prise de gaz additionnelle s'il n'est pas souhaitable d'avoir une telle prise de gaz additionnelle, et de contrôler de manière précise une telle prise de gaz, dans l'hypothèse où elle est souhaitée. It is in particular an object of the invention to provide a valve allowing precisely control the possible entry of additional gas, and particular, to prevent any additional gas intake if it is not desirable to have such an additional gas intake, and to precisely control such a gas intake, in the event that it is desired.

C'est en particulier un objet de l'invention que de fournir une valve dont le corps de valve est réalisé en matériau élastomérique, et autorisant un montage simple mais fiable d'un tube plongeur.It is in particular an object of the invention to provide a valve whose body valve is made of elastomeric material, and allowing mounting simple but reliable of a dip tube.

C'est un autre objet de l'invention que de fournir une valve dont le corps de valve est réalisé en matériau élastomérique, et autorisant de manière simple et effective, la réalisation d'une PGA.It is another object of the invention to provide a valve whose body valve is made of elastomeric material, and allowing in a simple and effective, the realization of a PGA.

D'autres objets de l'invention apparaítront de manière détaillée dans la description qui suit.Other objects of the invention will appear in detail in the description which follows.

Selon l'invention, ces objets sont atteints en réalisant une valve d'axe A pour la distribution sous pression d'un fluide comportant un corps de valve en matériau élastomérique, présentant un passage d'entrée et un passage de sortie, et un organe d'activation, ledit organe d'activation comprenant des moyens d'obturation pour, en réponse à une commande d'actionnement, mettre le passage d'entrée en communication avec le passage de sortie, des moyens de rappel élastique étant prévus pour en l'absence de commande d'actionnement, solliciter les moyens d'obturation en position fermée, la valve comprenant un élément rigide disposé à l'intérieur du passage d'entrée, et dont une portion émerge à l'extérieur du corps de valve, ledit élément étant traversé par un canal d'admission dont une première extrémité débouche hors du corps de valve, et dont une seconde extrémité débouche à l'intérieur du corps de valve, des moyens étant prévus de manière à former étanchéité entre ledit élément rigide et le passage d'entrée dans lequel est monté ledit élément rigide.According to the invention, these objects are achieved by producing an axis A valve for the pressure distribution of a fluid comprising a valve body of material elastomeric, having an inlet passage and an outlet passage, and a activation member, said activation member comprising means shutter to, in response to an actuation command, put the entry passage in communication with the exit passage, means for elastic return being provided for in the absence of an actuation command, request the closure means in the closed position, the valve comprising a rigid element arranged inside the entry passage, and a portion of which emerges outside the valve body, said element being crossed by a inlet channel, a first end of which opens out of the body of valve, and a second end of which opens out inside the valve body, means being provided so as to form a seal between said element rigid and the inlet passage in which said rigid element is mounted.

Ainsi, les seuls écoulements possibles, notamment gazeux, sont ceux permis via le canal d'admission traversant ledit élément rigide. Une telle étanchéité est assurée aussi bien en position d'ouverture que de fermeture de la valve. Dans le cas où une PGA est souhaitée, elle est réalisée par au moins un orifice, notamment radial, mettant en communication le canal d'admission avec le récipient, c'est à dire sans aucune portion délimitée ne serait-ce qu'en partie, par un élément élastomérique. Ceci permet de contrôler de façon relativement précise ladite PGA. Dans l'hypothèse où aucune PGA n'est requise, tout passage de gaz parasite est exclu entre la surface extérieure de l'élément rigide et la surface intérieure du passage d'entrée, et ce, en raison de la présence des moyens d'étanchéité.Thus, the only possible flows, notably gaseous, are those allowed via the intake channel passing through said rigid element. Such a seal is ensured both in the open and closed position of the valve. In if a PGA is desired, it is produced by at least one orifice, in particular radial, putting the intake channel into communication with the container, that is to say without any portion delimited even if only in part, by an elastomeric element. This makes it possible to control relatively specifies said PGA. In the event that no PGA is required, all passage of parasitic gas is excluded between the external surface of the element rigid and the interior surface of the entrance passage, due to the presence of sealing means.

De tels moyens d'étanchéité peuvent être constitués d'un organe maintenu en contact étanche sur la portion de surface extérieure du corps de valve dans laquelle débouche ledit passage d'entrée. De tels moyens peuvent en outre faciliter le positionnement dudit élément rigide dans le passage d'entrée. De plus, ils peuvent empêcher l'organe rigide de remonter de manière intempestive à l'intérieur du corps de valve.Such sealing means may consist of a member maintained in tight contact on the outer surface portion of the valve body in which opens said entry passage. Such means may further facilitate the positioning of said rigid element in the inlet passage. Of more, they can prevent the rigid organ from inadvertently rising inside the valve body.

Ladite portion émergente émerge de préférence de façon sensible pour, le cas échéant, permettre le montage d'une extrémité d'un tube plongeur, lorsque la valve est montée sur un réservoir contenant ledit fluide sous pression. Ainsi, cet élément rigide (par opposition à un matériau élastomérique, relativement mou), disposé dans le passage d'entrée, et émergeant à l'intérieur du réservoir, permet un accrochage simple et solide du tube plongeur. Dans l'hypothèse où les moyens d'étanchéité sont notamment réalisés sous forme d'un bourrelet annulaire, ils permettent de limiter l'enfoncement du tube plongeur autour dudit élément rigide, lorsque le tube plongeur est enfilé à force sur ledit élément rigide.Said emerging portion preferably emerges appreciably for the case if necessary, allow the mounting of one end of a dip tube, when the valve is mounted on a tank containing said fluid under pressure. So this rigid element (as opposed to a relatively soft elastomeric material), disposed in the inlet passage, and emerging inside the tank, allows a simple and solid attachment of the dip tube. Assuming the sealing means are in particular produced in the form of a bead annular, they limit the insertion of the dip tube around said rigid element, when the dip tube is force-fitted onto said element rigid.

Pour certaines compositions à distribuer, il peut être avantageux de prévoir au moins un orifice dans la portion émergente dudit élément rigide, de manière à réaliser au moins une prise de gaz additionnelle. L'orifice permet ainsi de mettre en communication le canal d'admission avec la partie supérieure du récipient, contenant un gaz propulseur. Le fait de réaliser l'orifice de PGA dans une pièce rigide, par exemple en polypropylène, permet de le dimensionner exactement à la taille nécessaire et suffisante pour jouer pleinement sa fonction, sans nuire à la bonne distribution du produit. L'orifice de PGA peut être réalisé dans le bourrelet mentionné ci-avant. On évite ainsi que l'orifice de PGA soit obturé par le tube plongeur.For certain compositions to be distributed, it may be advantageous to provide at least one orifice in the emerging portion of said rigid element, so as to make at least one additional gas intake. The opening thus allows connect the intake channel with the upper part of the container, containing a propellant. Making the PGA port in a rigid piece, for example made of polypropylene, makes it possible to size it exactly the size necessary and sufficient to fully play its function, without affecting the good distribution of the product. The PGA port can be made in the bead mentioned above. This prevents the orifice from PGA is closed by the dip tube.

Selon un mode de réalisation préféré, ledit élément rigide est solidaire de l'organe d'activation. On facilite dans une large mesure le montage de la valve selon l'invention. De même, on en réduit le coût en limitant le nombre de pièces.According to a preferred embodiment, said rigid element is integral with the activation organ. The assembly of the valve is greatly facilitated according to the invention. Likewise, the cost is reduced by limiting the number of rooms.

Les moyens d'obturation peuvent être reliés, du côté opposé audit élément rigide, à une tige émergente d'axe X, engagée de manière étanche à l'intérieur du passage de sortie, et émergeant de façon sensible à l'extérieur du corps de valve, ladite tige émergente étant traversée par un canal de distribution dont une première extrémité débouche à l'intérieur du corps de valve, en aval des moyens d'obturation, et dont une seconde extrémité débouche à l'extérieur du corps de valve pour la distribution du fluide sous pression. L'actionnement de la tige de valve peut se faire soit par basculement latéral, soit par enfoncement. Alternativement, la valve est du type "femelle". Dans cette hypothèse, les moyens d'obturation forment une cuvette centrale, apte à recevoir un embout mâle d'un organe d'actionnement.The closure means can be connected, on the side opposite to said element. rigid, with an emerging rod of axis X, engaged in a sealed manner inside from the outlet passage, and emerging appreciably outside the body of valve, said emerging rod being traversed by a distribution channel of which a first end opens into the valve body, downstream of the sealing means, and a second end of which opens outside the valve body for the distribution of pressurized fluid. The actuation of the valve stem can be done either by lateral tilting, or by depression. Alternatively, the valve is of the "female" type. In this hypothesis, the sealing means form a central bowl, capable of receiving a nozzle male of an actuator.

La tige émergente peut comprendre des moyens formant butée pour, lorsque la valve est utilisée avec une commande d'actionnement dirigée selon l'axe A de la valve, limiter l'enfoncement de la tige de valve dans le corps de valve. Une telle butée aide également au montage de l'organe d'activation dans le corps de valve, pour ne pas l'enfoncer trop loin.The emerging stem may include stop means for, when the valve is used with an actuation command directed along axis A of the valve, limit the insertion of the valve stem into the valve body. A such a stop also assists in mounting the activation member in the body valve, so as not to push it too far.

Selon le mode de réalisation préférentiel de l'invention, l'organe d'activation est réalisée d'une seule pièce, comportant la tige de valve, les moyens d'obturation, et l'élément destiné au montage du tube plongeur, et/ou à la réalisation de l'orifice de PGA. Le montage de la valve se fait par une seule opération de montage, ce qui limite en particulier les opérations de positionnement de chacune des pièces à l'intérieur du corps de valve. According to the preferred embodiment of the invention, the activation member is made in one piece, comprising the valve stem, the means shutter, and the element intended for mounting the dip tube, and / or for realization of the PGA orifice. The valve assembly is done by a single assembly operation, which in particular limits the operations of positioning of each of the parts inside the valve body.

Typiquement, le montage se fait en introduisant l'organe d'activation dans le corps de valve, via le passage de sortie. Alternativement, l'élément rigide destiné au montage du tube plongeur et/ou à la réalisation d'un orifice de PGA peut être formé d'un élément distinct de l'organe d'activation. En effet, on peut prévoir que cet élément de montage soit réalisé par bi-injection avec le corps de valve, un matériau rigide étant utilisé pour l'élément de montage, et un matériau élastomérique étant utilisé pour le corps de valve. Selon une alternative encore, la fixation de l'élément de montage sur le corps de valve est réalisée au moyens d'éléments d'accrochage (de type harpons) prévus sur le corps de valve, et /ou sur l'élément de montage.Typically, the assembly is done by introducing the activation member into the valve body, via the outlet passage. Alternatively, the rigid element intended for mounting the dip tube and / or for making a PGA orifice may be formed of a separate element from the activation member. Indeed, we can provide that this mounting element is made by bi-injection with the body valve, a rigid material being used for the mounting element, and a elastomeric material being used for the valve body. According to one alternatively, the fixing of the mounting element on the valve body is made by means of hooking elements (harpoons type) provided on the valve body, and / or on the mounting element.

Avantageusement, la tige émergente présente à l'intérieur du passage de sortie, un profil apte à coopérer avec un profil complémentaire du passage de sortie, lesdits profils étant tels, que quelle que soit la position angulaire de la tige par rapport à l'axe (A), ladite tige soit en contact annulaire étanche avec le passage de sortie. Un tel profil assure une bonne étanchéité, que la tige de valve soit à basculement latéral ou à enfoncement axial. Dans le cas d'une tige à enfoncement axial, un tel profil participe à solliciter les moyens d'obturation en position fermée lorsque cesse la commande d'actionnement.Advantageously, the emerging rod present inside the passage of outlet, a profile capable of cooperating with a profile complementary to the passage of outlet, said profiles being such that whatever the angular position of the rod relative to the axis (A), said rod is in sealed annular contact with the exit passage. Such a profile ensures a good seal, that the rod of valve either with lateral tilting or with axial insertion. In the case of a rod with axial insertion, such a profile participates in requesting the sealing means in the closed position when the actuation command ceases.

La tige peut présenter à l'intérieur du passage 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 (P), le passage 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, ladite tige étant apte, en réponse à une force exercée sensiblement perpendiculairement à l'axe A, à pivoter autour d'un point d'articulation de la tige coïncidant sensiblement avec le centre géométrique (P). A titre indicatif, la portion annulaire formant saillie présente un diamètre externe d'environ 5 à 7 mm, le reste de la tige ayant un diamètre compris entre 3 et 4 mm. The rod may have, inside the outlet passage, an annular portion projecting from the rest of the rod, and having a cross section is spherical, with a geometric center (P), the passage of outlet having a portion, forming a recess of shape complementary to that of the protruding portion, and capable of receiving, in a sealed manner, said protruding portion, said rod being adapted, in response to a force exerted substantially perpendicular to the axis A, to rotate around a point of articulation of the rod substantially coinciding with the geometric center (P). As an indication, the annular portion forming a projection has an external diameter about 5 to 7 mm, the rest of the stem having a diameter between 3 and 4 mm.

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.

L'expérience a montré que l'étanchéité réalisée se trouvait améliorée de façon substantielle quand, lorsque ledit renfoncement complémentaire 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. En effet, on obtient ainsi un serrage étanche de la tige dans le corps de valve, et ceci, quelle que soit la position angulaire de la tigeExperience has shown that the sealing achieved is improved in a way substantial when, when said additional recess is subjected to no elastic stress, it has a smaller radius of curvature from about 10% to about 30% at the radius of curvature of the protruding portion. In fact, a tight tightening of the rod is thus obtained in the valve body, and this, whatever the angular position of the rod

Les moyens d'obturation peuvent être formés d'une couronne d'étanchéité, qui, en absence de commande d'actionnement, est maintenue en appui étanche contre un siège annulaire formé autour du passage de sortie. 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 le corps de valve, et d'autre part, la couronne isole, en position de fermeture de la valve, le corps de valve du canal de distribution de la tige. Lorsque la tige de manoeuvre est actionnée à l'encontre des moyens de rappel élastique, par basculement latéral, la couronne s'écarte partiellement du siège annulaire, et une communication est établie entre le corps de valve et l'extérieur, permettant la distribution du produit sous pression.The sealing means may be formed by a sealing ring, which, in the absence of an actuation command, is held in sealed support against an annular seat formed around the outlet passage. So when the operating rod is at rest, the annular seat provides, on the one hand perfect seal between the external wall of the stem and the valve body, and on the other hand, the crown isolates, in the valve closed position, the body of stem delivery channel valve. When the operating rod is actuated against the elastic return means, by tilting lateral, the crown deviates partially from the annular seat, and a communication is established between the valve body and the outside, allowing the distribution of the product under pressure.

Pour assurer la mobilité de la couronne d'étanchéité dans le corps de valve, celui-ci peut présenter, entre le siège et le passage d'entrée, une portion tronconique dont un plus petit diamètre est orienté vers le passage d'entrée. Cette portion tronconique facilite, notamment, le basculement de la tige de manoeuvre. To ensure the mobility of the sealing ring in the valve body, this may present, between the seat and the entry passage, a portion frustoconical with a smaller diameter oriented towards the inlet passage. This frustoconical portion facilitates, in particular, the tilting of the rod maneuver.

Selon une alternative, la tige présente, à l'intérieur du passage de sortie, une portion formant un évidement sous forme d'une gorge annulaire en forme de portion de tore, présentant un centre géométrique (P), le passage 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, ladite tige étant apte, en réponse à une force exercée sensiblement perpendiculairement à l'axe A, à pivoter autour d'un point d'articulation de la tige coïncidant avec le centre géométrique (P) du tore.According to an alternative, the rod has, inside the outlet passage, a portion forming a recess in the form of an annular groove in the form of torus portion, having a geometric center (P), the exit passage having a protruding portion, of shape complementary to that of the recess, and capable of receiving, in a sealed manner, said annular groove, said rod being capable, in response to a force exerted substantially perpendicular to axis A, to pivot around a point of articulation of the rod coinciding with the geometric center (P) of the torus.

De la même manière que pour le précédent mode de réalisation, l'étanchéité réalisée est améliorée de façon substantielle quand, lorsque ladite portion formant saillie est soumise 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.In the same way as for the previous embodiment, the sealing achieved is improved substantially when, when said portion protruding is subjected to no elastic stress, this presents a radius of curvature about 10% to about 30% less than the radius of curvature of the portion forming a recess.

De préférence, la distance, selon l'axe X, entre le point d'articulation (P) et le siège annulaire, est comprise entre 3 mm et 4 mm.Preferably, the distance, along the X axis, between the point of articulation (P) and the annular seat, is between 3 mm and 4 mm.

De préférence, le canal de distribution débouche à l'intérieur du corps de valve par l'intermédiaire d'un passage traversant la tige radialement.Preferably, the distribution channel opens out inside the valve body via a passage through the rod radially.

De préférence, le corps de valve comporte des moyens d'accrochage extérieurs aptes à coopérer avec une ouverture délimitée par un bord libre dudit réservoir. De tels moyens d'accrochage peuvent être constitués par une gorge annulaire.Preferably, the valve body includes attachment means exteriors able to cooperate with an opening delimited by a free edge of said reservoir. Such attachment means can be constituted by a annular groove.

Le matériau élastomérique formant le corps de valve peut présenter une dureté Shore A comprise dans la gamme allant de 30 à 70. Ainsi, on confère au corps de valve à la fois suffisamment d'élasticité pour pouvoir y monter l'organe d'activation 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 le corps de valve, ces plots peuvent être déformés par écrasement, lors de l'actionnement de la valve.The elastomeric material forming the valve body may have a hardness Shore A included in the range from 30 to 70. Thus, the body is given valve at the same time enough elasticity to be able to mount the organ of activation and sufficient rigidity to ensure its shape stability. In moreover, when the return means are produced in the form of supported studs by one of the walls delimiting the valve body, these studs can be deformed by crushing, when the valve is actuated.

Avantageusement, lesdits moyens de rappel élastiques sont constitués par au moins un plot élastomérique porté par une paroi intérieure du corps de valve, et disposé de sorte que les moyens d'obturation puissent, en réponse à une commande d'actionnement, venir en engagement élastique avec ledit (ou lesdits) plot(s). De tels plots sont espacés uniformément tout autour de la surface interne du corps de valve, de manière à permettre au produit, en position ouverte de la valve, de passer entre les plots. Lorsque le corps 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.Advantageously, said elastic return means are constituted by at less an elastomeric stud carried by an inner wall of the valve body, and arranged so that the sealing means can, in response to a actuation command, come into elastic engagement with said (or said) stud (s). Such studs are evenly spaced all around the internal surface of the valve body, so as to allow the product, in open position of the valve, to pass between the studs. When the body of valve has a bottom consisting of a frustoconical portion, this (or these) stud (s) is (or are) disposed (s) on this frustoconical portion. Advantageously, the number of pads is 4 or 6. These pads are preferably of low dimension relative to the chamber, for example a height of the order of 0.5 mm to 3 mm.

Les moyens de rappel élastique peuvent être constitués par au moins un plot porté par les moyens d'obturation, et apte, en réponse à une commande d'actionnement, à venir en engagement élastique avec une portion correspondante de la paroi intérieure du corps de valve.The elastic return means can consist of at least one stud carried by the sealing means, and capable, in response to an order actuation, to come in elastic engagement with a portion corresponding to the inner wall of the valve body.

Selon un autre aspect de l'invention, on réalise également un distributeur comportant un réservoir rempli d'un produit fluide sous pression et une valve pour la distribution dudit produit, caractérisé en ce que la valve est formée d'une valve selon la présente invention.According to another aspect of the invention, a distributor is also produced comprising a reservoir filled with a fluid under pressure and a valve for dispensing said product, characterized in that the valve is formed of a valve according to the present invention.

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'accrochage 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 container neck. In this case, the neck is shaped so that it can cooperate with the means for attaching the valve.

Grâce aux moyens d'accrochage 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 attachment means mentioned above the assembly of the body valve on the container can be performed without the need for recourse to a conventional cup, because the elasticity of the material constituting the valve body on the one hand, ensures the deformation necessary for mounting it on the container, and on the other hand, a sufficient seal to withstand the pressure internal container.

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 un bord libre délimitant une ouverture, et apte à coopérer avec les moyens d'accrochage du corps de valve.The container that can be used for mounting this valve can be chosen from aluminum, tin or plastic containers. To this end, the container has a free edge delimiting an opening, and able to cooperate with the means for attaching 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 économiquement avantageux. A cet effet, l'ouverture du récipient dans laquelle 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 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 and economical containers advantageous. For this purpose, the opening 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 expensive.

La valve 1 représentée à la figure 1, est du type à enfoncement. Elle comporte un corps 2 ayant une forme générale en tronc de cône d'axe de révolution A, et un organe d'activation 400, comportant 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. L'organe d'activation 400 est réalisé en un matériau thermoplastique rigide, notamment en polypropylène.The valve 1 shown in Figure 1 is of the push-in type. It involves a body 2 having a general truncated cone shape with an axis of revolution A, and an activation member 400, comprising an operating rod 3, in the form generally cylindrical, provided with an X axis. In the rest position of the valve, axes A and X are merged. The activation member 400 is produced in a rigid thermoplastic material, in particular polypropylene.

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 valve body 2 is made of an elastically material deformable, for example a nitrile rubber elastomer, the hardness of which Shore A is in the range between 30 and 70. The body has a large base 2a and a small base 2b, connected by a part frustoconical 2c and a cylindrical part 2d.

A l'intérieur du corps de valve 2 est ménagée une chambre interne 4, délimitée par des parois latérales 4a, 4b, 4c, 4d. La paroi 4a est de forme cylindrique et est raccordée à une portion tronconique 4b dont le sommet est orienté vers un passage d'entrée cylindrique 5. Du côté opposé à la portion tronconique 4b, la paroi 4a est reliée, via un plateau annulaire 4c, à une portion tronconique 4d orientée à l'opposé de la portion tronconique 4b.Inside the valve body 2 is provided an internal chamber 4, delimited by side walls 4a, 4b, 4c, 4d. The wall 4a is of cylindrical shape and is connected to a frustoconical portion 4b, the top of which is oriented towards a cylindrical inlet passage 5. On the side opposite to the frustoconical portion 4b, the wall 4a is connected, via an annular plate 4c, to a frustoconical portion 4d oriented opposite the frustoconical portion 4b.

Le passage d'entrée 5, destiné à l'admission du produit à distribuer, est pratiqué au centre de la petite base 2b et débouche dans la chambre 4.The inlet passage 5, intended for the admission of the product to be dispensed, is practiced in the center of the small base 2b and leads into room 4.

Le plateau annulaire 4c, mentionné précédemment, constitue 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. Le sommet de la portion tronconique 4d débouche dans un passage de sortie 10 qui est disposé en alignement avec le passage d'entrée 5, le passage 10 conduisant, depuis la chambre interne 4, vers l'extérieur. A l'intérieur du passage de sortie 10 est disposée la tige 3 de l'organe d'activation 400, la paroi externe de la tige 3 étant en contact d'étanchéité parfaite contre la paroi délimitant le passage de sortie 10. A l'extérieur du corps de valve, du côté opposé au réservoir, la tige 3 présente une collerette annulaire 107, apte à venir en butée contre le bord du corps de valve 2 délimitant le passage de sortie 10. Une telle collerette participe au montage de l'organe d'activation 400 à l'intérieur du corps de valve, en évitant que la tige de valve 3 soit enfoncée trop loin dans le corps de valve 2. En outre elle limite les mouvements axiaux de l'organe d'activation 400 lorsque la tige de valve 3 est du type à enfoncement.The annular plate 4c, mentioned above, constitutes an annular zone seal 4c located in a plane perpendicular to the axis A. The annular zone 4c is extended upwards by a second frustoconical portion 4d. The top of the frustoconical portion 4d opens into an outlet passage 10 which is arranged in alignment with the inlet passage 5, the passage 10 leading, from the internal chamber 4, towards the outside. Inside exit passage 10 is arranged the rod 3 of the activation member 400, the external wall of the rod 3 being in perfect sealing contact against the wall delimiting the passage of outlet 10. Outside the valve body, on the side opposite the reservoir, the rod 3 has an annular flange 107, capable of abutting against the edge of the valve body 2 delimiting the outlet passage 10. Such a flange participates mounting the activation member 400 inside the valve body, avoiding the valve stem 3 is pushed too far into the valve body 2. In addition it limits the axial movements of the activation member 400 when the rod of valve 3 is of the push-in type.

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 15 traversant la tige radialement et aboutissant dans la partie supérieure de la chambre 4. L'organe d'activation 400 comporte également un élément d'obturation 100, solidaire de la tige de valve 3, et disposé à l'intérieur de la chambre 4. L'élément d'obturation 100 est conformé en tronc de cône, 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 (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 l'élément d'obturation 100. 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 4 et le canal de distribution 12. Selon un autre mode de réalisation, les plots 20 peuvent être réalisés sur la partie tronconique 18 de l'élément 100 de l'organe d'activation 400, et moulés intégralement avec celui-ci. 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.The rod 3 comprises a central distribution channel 12 passing through the rod from the emerging end 3b to a height situated substantially at the height of the annular zone 4c. At this height, the central channel 12 ends in a passage 15 passing through the rod radially and ending in the upper part of the chamber 4. The activation member 400 also includes a shutter element 100, integral with the rod of valve 3, and placed inside the chamber 4. The shutter element 100 is in the form of a truncated cone, comprising a large 16 and a small 17 bases connected by a frustoconical part 18. The large base 16 carries a peripheral ring 19 in sealed elastic support against the annular zone 4c, which then constitutes a seat. In practice, the crown has a small thickness radially (approximately 0.1 to 0.5 mm, see FIG. 2). The elastic support of the crown 19 against the seat 4c is provided by several studs 20, distributed regularly on the frustoconical wall 4b of the chamber 4 and in elastic support against the frustoconical part 18 of the closure element 100. Thus, the free edge of the crown 19 enters by some 10 th of mm in the seat 4c and creates a perfect seal between the valve chamber 4 and the distribution channel 12. According to another embodiment, the studs 20 can be produced on the frustoconical part 18 of the element 100 of the activating member 400, and molded integrally therewith. These studs are in elastic support against the frustoconical wall 4b. Thus, when the valve is actuated by tilting the rod 3, the studs partially enter the wall 4b.

Du côté opposé à la tige émergente 3, l'organe d'activation 400, se prolonge par un élément 101, relié à l'organe d'obturation 100, et inséré de manière étanche dans le passage d'entrée 5 du corps de valve 2. L'élément 101 a une portion 109 émergeant de façon sensible à l'intérieur du réservoir, hors du corps de valve. L'élément 101 est traversé par un canal d'admission 102 dont une extrémité débouche axialement dans le réservoir, et dont l'autre extrémité débouche dans un passage radial 103 débouchant à l'intérieur de la chambre 4, au voisinage de sa portion inférieure. L'élément 101 forme partie intégrante de l'organe d'activation 400. Selon une caractéristique importante de l'invention, la portion 109 de l'élément 101 forme un bourrelet annulaire 104 destiné à venir en contact étanche contre le bord 2b du corps de valve 2, autour de l'orifice d'entrée du passage d'entrée 5, empêchant ainsi tout passage de gaz parasite à l'extérieur de l'élément 101. Outre l'étanchéité, le bourrelet 104 participe au maintien de l'organe d'activation 400 à l'intérieur du corps de valve 2. En outre, le bourrelet 104 est traversé par un passage radial 105 formant un orifice de prise de gaz additionnel. Le passage 105 débouche d'une part à l'intérieur du réservoir, au dessus du niveau de produit, de manière à être en communication avec le gaz contenu au dessus de la surface libre du produit, et d'autre part, à l'intérieur du canal d'admission.On the side opposite to the emerging rod 3, the activation member 400, is extended by an element 101, connected to the shutter member 100, and inserted in a sealed manner in the inlet passage 5 of the valve body 2. The element 101 has a portion 109 emerging appreciably inside the tank, outside the valve body. The element 101 is crossed by an intake channel 102, one end of which opens axially into the tank, and the other end of which opens into a radial passage 103 opening into the interior of the chamber 4, in the vicinity of its lower portion. Element 101 forms an integral part of the organ activation 400. According to an important characteristic of the invention, the portion 109 of the element 101 forms an annular bead 104 intended to come into contact watertight against the edge 2b of the valve body 2, around the inlet port of the inlet passage 5, thus preventing any passage of parasitic gas outside of element 101. In addition to sealing, the bead 104 participates in maintaining the activation member 400 inside the valve body 2. In addition, the bead 104 is crossed by a radial passage 105 forming a gas intake orifice additional. The passage 105 opens on the one hand inside the tank, at the above the product level, so as to be in communication with the gas content above the free surface of the product, and on the other hand, inside the intake channel.

Le bourrelet 104 forme en outre une butée axiale apte à limiter l'enfoncement d'un tube plongeur 6 sur l'extrémité libre de l'élément 101. Typiquement, l'enfoncement du tube plongeur sur l'extrémité libre de l'élément 101 se fait sur une hauteur axiale d'environ 5 à 7 mm. La tenue du tube plongeur 6 sur l'élément 101 est améliorée par la présence d'un harpon d'accrochage 106.The bead 104 also forms an axial stop capable of limiting the sinking a dip tube 6 on the free end of the element 101. Typically, the insertion of the dip tube on the free end of the element 101 is done on an axial height of approximately 5 to 7 mm. The holding of the dip tube 6 on the element 101 is improved by the presence of a hanging harpoon 106.

Avantageusement, l'organe d'activation 400 est obtenu de moulage d'un matériau thermoplastique relativement rigide comme le polypropylène. Alternativement, ledit organe d'activation peut être réalisé en deux pièces, rendues solidaires l'une de l'autre par toute technique appropriée (collage, soudure, montage en force, etc.).Advantageously, the activation member 400 is obtained by molding a relatively rigid thermoplastic material such as polypropylene. Alternatively, said activation member can be produced in two parts, made integral with each other by any appropriate technique (bonding, welding, strength mounting, etc.).

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'accrochage sous forme d'une gorge annulaire 108 de fixation apte à coopérer avec un bord libre 7 du réservoir, délimitant une ouverture dans laquelle est montée la valve 1.A transition zone of the valve body, located between the cylindrical part 2d and the frustoconical part 2c of the body 2, comprises means for hooking under shape of an annular groove 108 for fixing capable of cooperating with a free edge 7 of the reservoir, delimiting an opening in which the valve 1 is mounted.

Le fonctionnement de cette valve est le suivant. Par l'intermédiaire d'un bouton poussoir (non représenté), l'utilisateur exerce une pression axiale sur l'organe d'activation 400, laquelle pression provoque l'enfoncement de la tige de valve 3. Lors de cet enfoncement, la couronne d'étanchéité 19 se décolle du siège 4c. Le produit remonte depuis le réservoir, par le tube plongeur 6, débouche dans la chambre 4, par le passage 103. Le produit passe entre la couronne annulaire 19 et le siège 4c et entre dans le canal de distribution 12 par l'intermédiaire du passage radial 15. Le produit sort alors par l'orifice de sortie 3b. En relâchant la pression sur l'organe d'activation 400, la tige de valve 3, sous l'action de rappel élastique produite par les plots 20, remonte jusqu'à ce que la couronne annulaire 19 soit en appui étanche sur le siège 4c.The operation of this valve is as follows. Via a button push button (not shown), the user exerts an axial pressure on the organ activation 400, which pressure causes the valve stem to sink 3. During this insertion, the sealing ring 19 comes off the seat 4c. The product rises from the tank, through the dip tube 6, opens in chamber 4, through passage 103. The product passes between the crown ring 19 and seat 4c and enters distribution channel 12 through through the radial passage 15. The product then exits through the outlet orifice 3b. By releasing the pressure on the activation member 400, the valve stem 3, under the elastic return action produced by the studs 20, goes up until that the annular ring 19 is in leaktight support on the seat 4c.

Dans le mode de réalisation des figures 2 et 3 auxquelles il est maintenant fait référence, la valve se distingue du mode de réalisation précédent par la présence de moyens assurant une meilleure étanchéité entre la tige de valve 3 et le passage de sortie 10. De tels moyens sont particulièrement adaptés dans le cas d'une valve à basculement latéral, mais présentent également un intérêt dans le cas d'une valve à enfoncement. Dans la description qui suit, seuls les éléments nouveaux par rapport au mode de réalisation précédent, seront décrits en détail.In the embodiment of Figures 2 and 3 which is now made reference, the valve differs from the previous embodiment by the presence of means ensuring a better seal between the valve stem 3 and the outlet passage 10. Such means are particularly suitable in the case of a side-tilt valve, but are also of interest in the case of a push-in valve. In the following description, only the new elements compared to the previous embodiment, will be described in detail.

Sensiblement à mi-hauteur du passage 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 passage de sortie 10 comporte un alésage conique, tandis que l'autre extrémité 13 du passage de sortie forme la portion tronconique 4d précitée.Substantially halfway up the outlet passage 10, the rod 3 has a annular portion 14 projecting from the rest of the rod, and the cross section, axial is spherical, complementary to the shape of the recess 8. A free end 11 of the outlet passage 10 has a tapered bore, while the other end 13 of the passage of outlet forms the aforementioned frustoconical portion 4d.

Le diamètre de la tige est d'environ 3 mm à environ 4 mm, sa portion annulaire externe formant saillie 14 ayant un diamètre compris maximal entre 4 mm et 7 mm. Dans ce cas, le renfoncement complémentaire 8, ménagé dans le passage de sortie 10, 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 diameter of the rod is from about 3 mm to about 4 mm, its annular portion external protrusion 14 having a maximum diameter between 4 mm and 7 mm. In this case, the complementary recess 8, formed in the passage outlet 10, when subjected to no elastic stress, has a internal diameter approximately 10% to 30% less than the external diameter of the portion protruding 14. Advantageously, the center P of the protruding portion 14 located at an axial height along axis A, located 3 mm to 4 mm from seat 4c.

Le fonctionnement de la valve 1 est schématisé sur la figure 3. 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 l'organe d'activation 400, et en particulier de la tige 3 est incliné par rapport à l'axe A du corps de valve, l'angle a formé entre les deux axes étant de l'ordre de 2° à 10°. Il est à noter que l'ensemble du corps de valve 2 se déforme en réponse à ce basculement de la tige 3 de sorte que l'étanchéité entre l'élément 101 et le passage d'entrée 5 est maintenue tout pendant l'actionnement. Lors de ce pivotement, une partie 19a de la couronne 19 s'éloigne du siège 4c. En même temps, le (ou les) plot(s) 20 qui se trouve(nt) sur la paroi tronconique 4b, du côté opposé à la partie de la couronne 19 qui s'éloigne du siège 4c, est (sont) écrasé(s) par la partie tronconique 18 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 le canal 102, dans la chambre 4, pour arriver dans le canal de distribution 12. Lorsque cesse l'actionnement, 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 passage 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 valve 1 is shown diagrammatically in FIG. 3. To cause opening the valve 1, the rod 3 is pivoted around the hinge point P, in the direction of arrow B. During this pivoting, the X axis of the activation member 400, and in particular of the rod 3 is inclined relative to to the axis A of the valve body, the angle formed between the two axes being of the order from 2 ° to 10 °. It should be noted that the entire valve body 2 deforms into response to this tilting of the rod 3 so that the seal between the element 101 and the entry passage 5 is maintained throughout during actuation. When from this pivoting, a part 19a of the ring 19 moves away from the seat 4c. In at the same time, the pad (s) 20 which is (are) on the frustoconical wall 4b, on the side opposite to the part of the crown 19 which moves away from the seat 4c, is (are) crushed by the frustoconical part 18 of the rod. In the example of realization considered, four pads 20 of elongated shape were made of height of about 1 mm, width of about 1.5 mm and length about 1.5 mm. Under the thrust of a propellant, the product is then routed via the dip tube 6 and the channel 102, in the chamber 4, to arrive in the distribution channel 12. When the actuation ceases, the distribution of the product stops, because the crown 19 returns to leaktight contact against seat 4c. Thus, during the pivoting of the rod in the passage of outlet, it remains in sealed annular contact with the channel, at all or part of its spherical portion 14.

Il est à noter que la valve telle que représentée aux figures 2 et 3 peut être utilisée aussi bien en basculement qu'en enfoncement. Dans l'hypothèse où la valve est utilisée en enfoncement, les profils complémentaires 8 et 14, outre l'étanchéité entre la tige de valve 3 et le passage de sortie 10, favorisent en raison de leurs profils respectifs, le retour par rappel élastique de la tige de valve 3 en position fermée. Quel que soit le mode de fonctionnement, le bourrelet 104 reste en contact étanche contre la surface 2b du corps de valve, même en cours d'actionnement de la valve, les contraintes d'actionnement étant absorbées par le matériau élastomérique.It should be noted that the valve as shown in Figures 2 and 3 can be used both in tilting and driving. In the event that the valve is used when driving in, additional profiles 8 and 14, in addition to the seal between the valve stem 3 and the outlet passage 10, favor in because of their respective profiles, the return by elastic return of the rod valve 3 in closed position. Whatever the operating mode, the bead 104 remains in sealed contact against the surface 2b of the valve body, even during valve actuation, actuation constraints being absorbed by the elastomeric material.

Sur la figure 4, on a représenté une variante du mode de réalisation des figures 2 et 3. Cette valve, représentée en position de repos, se distingue de la valve des figures 2 et 3 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. De la même manière que pour les modes de réalisation précédents, un bourrelet 104 est en appui étanche contre la surface 2b du corps de valve, de manière à empêcher tout écoulement intempestif de gaz entre la surface externe de l'élément 101 et la surface intérieure délimitant le passage d'entrée 5. Le gaz ne peut entrer à l'intérieur du corps de valve, uniquement via l'orifice 105 traversant radialement le bourrelet 104.In FIG. 4, a variant of the embodiment of the figures is shown. 2 and 3. This valve, shown in the rest position, differs from the valve Figures 2 and 3 by the fact that the shape of the profile of the annular portion of the rod, as well as the shape of the complementary profile of the outlet channel are reversed. In the same way as for the previous embodiments, a bead 104 is sealingly pressed against the surface 2b of the valve body, so as to prevent any inadvertent flow of gas between the surface external of element 101 and the internal surface delimiting the entry passage 5. Gas cannot enter inside the valve body, only through the orifice 105 crossing radially the bead 104.

Ainsi, la tige 3 présente, à l'intérieur du canal de sortie, sensiblement à mi-hauteur, une portion 14 formant un évidement sous forme d'une gorge annulaire en forme de portion de tore, présentant un centre géométrique P, le canal de sortie 10 ayant une portion 8 formant saillie, de forme complémentaire à celle de l'évidement 14, et apte à recevoir de manière étanche la gorge annulaire, le point d'articulation de la tige 3 coïncidant avec le centre géométrique P du tore. Le fonctionnement de la valve selon ce mode de réalisation est analogue au fonctionnement de la valve du mode de réalisation des figures 2 et 3.Thus, the rod 3 has, inside the outlet channel, approximately halfway up, a portion 14 forming a recess in the form of a groove annular in the shape of a torus portion, having a geometric center P, the outlet channel 10 having a portion 8 projecting, of complementary shape to that of the recess 14, and capable of sealingly receiving the groove annular, the point of articulation of the rod 3 coinciding with the center geometric P of the torus. The operation of the valve according to this mode of embodiment is analogous to the operation of the valve of the embodiment Figures 2 and 3.

Sur la figure 5, on voit la valve conforme à la figure 4, 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, dont un bord libre 7 délimite un orifice pour le montage de la valve.In Figure 5, we see the valve according to Figure 4, mounted on a container 202 without valve holder cup. This container is an aluminum bottle, in particular in one piece, or in a rigid plastic material such as polyethylene terephthalate (PET). The container 202 has a neck 204 of which the open end is folded back square forming an annular plate 206, of which a free edge 7 delimits an orifice for mounting the valve.

Dans l'orifice du récipient 202 est fixé le corps de valve 2, par enfoncement de celui-ci, de sorte que le plateau annulaire 206 vienne se loger dans la gorge annulaire 108 du corps de valve 2. Du fait de l'élasticité du corps 2, le montage de ce dernier dans l'ouverture du récipient 202 peut être effectué par une opération simple. De plus, lorsque l'ouverture 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 orifice of the container 202 is fixed the valve body 2, by pushing in this one, so that the annular plate 206 comes to be housed in the groove annular 108 of the valve body 2. Due to the elasticity of the body 2, the mounting of the latter in the opening of the container 202 can be effected by a simple operation. In addition, when the opening has variations in diameter, relatively large tolerances are compensated by elasticity valve body, without risk of leakage of propellant gas. This assembly is particularly advantageous from the economic point of view.
