Description

La présente invention concerne un dispositif de distribution de produit fluide destiné à être associé à un réservoir de produit fluide pour ainsi former un distributeur de produit fluide. Lorsque le produit fluide est pulvérisé sous la forme de fines gouttelettes, le distributeur est souvent désigné sous le terme de « vaporisateur ». Le domaine d'application privilégié de la présente invention est celui de la parfumerie ou de la cosmétique, mais peut bien entendu s'appliquer à d'autres domaines où une distribution de produit fluide est nécessaire. US 1 373 505 décrit un dispositif selon le préambule de la revendication 1.The present invention relates to a fluid dispenser device intended to be associated with a fluid reservoir to thereby form a fluid dispenser. When the fluid product is sprayed in the form of fine droplets, the dispenser is often referred to as a "vaporizer". The preferred field of application of the present invention is that of perfumery or cosmetics, but can of course be applied to other areas where a distribution of fluid product is necessary. US 1,373,505 describes a device according to the preamble of claim 1.

Le dispositif de distribution de l'invention est d'un type particulier assurant une distribution mélangée ou bi-phasique du produit fluide avec un gaz de propulsion, conventionnellement de l'air. Le dispositif de distribution comprend ainsi généralement un orifice de distribution de produit fluide par lequel le mélange de produit fluide et d'air est distribué sous forme pulvérisée. Le dispositif comprend également un conduit d'air sous pression ayant une extrémité aval débouchant à proximité de l'orifice de distribution, et une chasse d'air, telle qu'une poire souple écrasable, reliée à une extrémité amont du conduit d'air pour alimenter un flux d'air sous pression à travers le conduit d'air jusqu'à l'orifice de distribution. Le dispositif comprend aussi un canal de produit fluide qui se raccorde au conduit d'air à proximité ou au niveau de son extrémité aval, le produit fluide dans le canal étant aspiré par le flux d'air sous pression par effet Venturi, de manière à distribuer un mélange d'air et de produit fluide à travers l'orifice de distribution. Ce type de dispositif de distribution est souvent désigné sous le terme de « pompe à poire », qui provient de l'utilisation d'une chasse d'air sous la forme d'une poire souple écrasable. Ce type de dispositif de distribution est connu depuis longtemps, et confère aujourd'hui un effet classique ou rétro au distributeur de produit fluide. L'utilisation d'un tel distributeur se fait en maintenant le réservoir d'une main et en écrasant la poire de l'autre main. L'orifice de distribution est solidaire du réservoir, de sorte que c'est la main qui tient le réservoir qui dirige l'orifice de distribution et ainsi le jet de produit pulvérisé. Dans ce genre de dispositif de distribution, le mélangé d'air et de produit fluide est effectué à proximité de l'orifice de distribution ou quelque peu en amont de celui-ci. En écrasant la poire souple, de l'air est refoulé sous pression à travers le conduit d'air en direction de l'orifice de distribution. Ce flux d'air a pour effet de créer une dépression à l'intérieur du canal de produit fluide qui est généralement relié au réservoir par un tube plongeur. En conséquence, le produit fluide présent dans le canal de produit fluide est aspiré par le flux d'air sous pression par un phénomène d'effet Venturi bien connu. Ainsi, du produit fluide issu du canal est introduit dans le flux d'air sortant du conduit d'air. Le produit fluide se mélange avec le flux d'air et le mélange ainsi obtenu est expulsé à travers l'orifice de distribution sous la forme de fines gouttelettes de produit fluide.The dispensing device of the invention is of a particular type ensuring a mixed or bi-phasic distribution of the fluid product with a propellant gas, conventionally air. The dispensing device thus generally comprises a fluid dispensing orifice through which the mixture of fluid and air is dispensed in pulverized form. The device also comprises a pressurized air duct having a downstream end opening near the dispensing orifice, and an air flush, such as a collapsible soft bulb, connected to an upstream end of the air duct. for supplying a flow of pressurized air through the air duct to the dispensing orifice. The device also comprises a fluid product channel which connects to the air duct near or at its downstream end, the fluid product in the channel being sucked by the flow of air under pressure by Venturi effect, so as to distribute a mixture of air and fluid through the dispensing orifice. This type of dispensing device is often referred to as a "pear pump", which comes from the use of a flush of air in the form of a crushable soft pear. This type of dispensing device has been known for a long time, and today gives a classic or retro effect to the fluid dispenser. The use of such a dispenser is done by holding the tank with one hand and crushing the pear with the other hand. The dispensing orifice is integral with the reservoir, so that it is the hand that holds the reservoir which directs the dispensing orifice and thus the jet of sprayed product. In this type of dispensing device, the mixture of air and fluid product is carried out near the dispensing orifice or somewhat upstream of it. By crushing the soft bulb, air is forced under pressure through the air duct towards the dispensing orifice. This air flow has the effect of creating a vacuum inside the fluid channel which is generally connected to the tank by a dip tube. Consequently, the fluid product present in the fluid product channel is sucked by the flow of pressurized air by a well-known Venturi effect phenomenon. Thus, the fluid product from the channel is introduced into the air flow leaving the air duct. The fluid product mixes with the air flow and the mixture thus obtained is expelled through the dispensing orifice in the form of fine droplets of fluid product.

L'actionnement de la chasse d'air (poire) peut ainsi être divisé en deux phases, à savoir une phase d'écrasement élastique et une phase de détente élastique. Lors de la phase d'écrasement, le volume utile de la chasse est réduit, de sorte que l'air qu'elle contient est mis sous pression et refoulé à travers une ouverture vers le conduit d'air. Lors de la phase de détente, le volume utile de la chasse augmente sous l'effet de la mémoire élastique de la chasse, et de l'air extérieur doit donc pénétrer à l'intérieur de la chasse. Conventionnellement, la chasse d'air comprend une extrémité au niveau de laquelle est formée l'ouverture reliée au conduit d'air et une autre extrémité opposée au niveau de laquelle est prévu un clapet d'entrée d'air qui est ouvert lors des phases de détente élastique et fermé lors des phases d'écrasement élastique. Par conséquent, une chasse classique comprend deux ouvertures distinctes et séparées, ce qui complique d'une part la fabrication et le montage de la chasse d'air et nuit d'autre part à son aspect esthétique global.The actuation of the flush (pear) can thus be divided into two phases, namely an elastic crushing phase and an elastic expansion phase. During the crushing phase, the effective volume of the flush is reduced, so that the air contained therein is pressurized and discharged through an opening to the air duct. During the relaxation phase, the effective volume of the hunt increases under the effect of the elastic memory of the hunt, and outside air must therefore penetrate inside the hunt. Conventionally, the air flush comprises an end at which the opening connected to the air duct is formed and another opposite end at which an air inlet flap is provided which is open during the phases. resilient and closed relaxation during the phases of elastic crushing. Therefore, a conventional hunt includes two separate and separate openings, which complicates on the one hand the manufacture and assembly of the air flush and night on the other hand to its overall aesthetic appearance.

La présente invention a pour but de remédier à cet inconvénient précité de l'art antérieur en définissant un dispositif de distribution de produit fluide du type « pompe à poire » dont la chasse d'air est plus simple à fabriquer et présente un meilleur aspect esthétique.The object of the present invention is to overcome this aforementioned disadvantage of the prior art by defining a fluid dispenser device of the "pear pump" type, the flushing of which is simpler to manufacture and has a better aesthetic appearance. .

Pour ce faire, la présente invention propose un dispositif de distribution de produit fluide selon la revendication 1. En d'autres termes, le clapet d'entrée d'air a été déplacé d'une extrémité de la chasse d'air à l'autre extrémité où est formée l'ouverture pourvue du manchon de raccord. Une ouverture a ainsi été supprimée au niveau de la chasse d'air qui n'en comprend alors qu'une seule. On peut ainsi réaliser des chasses d'air avec les formes les plus diverses, étant donné qu'il n'est plus nécessaire de prévoir une ouverture spécifique pour le clapet d'entrée d'air. Avantageusement, le clapet d'entrée d'air est disposé au centre de l'ouverture et le flux d'air sous pression qui s'écoule vers le conduit d'air est dirigé sur le clapet d'entrée d'air, le flux d'air sous pression passant ensuite autour du clapet. En variante, le clapet d'entrée d'air est disposé autour du flux d'air sous pression. D'une manière où d'une autre, on assure que le clapet d'entrée d'air est appuyé de manière étanche sur son siège lors des phases d'écrasement élastique.To do this, the present invention provides a fluid dispenser device according to claim 1. In other words, the air inlet valve has been moved from one end of the flush to the air outlet. another end where is formed the opening provided with the coupling sleeve. An opening has been removed at the level of the flush which then includes only one. It is thus possible to perform air evacuation with the most diverse forms, since it is no longer necessary to provide a specific opening for the air inlet valve. Advantageously, the air inlet valve is disposed at the center of the opening and the air flow under pressure that flows to the air duct is directed to the air inlet valve, the flow of pressurized air then passing around the valve. Alternatively, the air inlet valve is disposed around the flow of air under pressure. In one way or another, it is ensured that the air inlet valve is pressed in a sealed manner on its seat during the phases of elastic crushing.

Selon une autre caractéristique avantageuse de l'invention, le manchon de raccord peut comprendre également un clapet anti-retour empêchant une aspiration de produit fluide à travers le conduit d'air jusque dans la chasse lors des phases de détente élastique. Avantageusement, le clapet anti-retour coopère avec un siège de clapet de manière à reposer sur son siège lors des phases de détente élastique. En variante, le clapet anti-retour comprend une fente auto-jointante qui s'ouvre sous la pression du flux d'air généré lors des phases d'écrasement élastique et qui se ferme hermétiquement lors des phases de détente élastique. En variante, le clapet d'entrée d'air et le clapet anti-retour sont solidaires l'un de l'autre en déplacement. Avantageusement, le clapet d'entrée d'air et la fente auto-jointante sont réalisés en une seule pièce de clapet, en une seule matière ou par bi injection de deux matières différentes. Selon une forme de réalisation pratique, la pièce de clapet comprend une douille de fixation sensiblement rigide, pourvue d'un côté d'un dôme formé avec la fente auto-jointante et de l'autre côté d'une membrane souple annulaire qui s'étend vers l'extérieur et qui sert de clapet d'entrée d'air.According to another advantageous characteristic of the invention, the coupling sleeve may also comprise a non-return valve preventing a suction of fluid product through the air duct into the flush during elastic expansion phases. Advantageously, the non-return valve cooperates with a valve seat so as to rest on its seat during elastic expansion phases. Alternatively, the non-return valve comprises a self-sealing slot which opens under the pressure of the air flow generated during the elastic crushing phases and which closes tightly during the elastic expansion phases. Alternatively, the air inlet valve and the non-return valve are integral with each other in displacement. Advantageously, the air inlet valve and the self-sealing slot are made in one piece of valve, in a single material or by two injection of two different materials. According to a practical embodiment, the valve member comprises a substantially rigid fixing sleeve, provided on one side with a dome formed with the self-sealing slot and on the other side with a flexible annular membrane which is extends outward and serves as an air inlet valve.

Un principe de l'invention est de regrouper les flux d'air sortant et/ou entrant de la chasse au niveau d'une ouverture unique pourvue d'un manchon de raccord pour le raccordement de la chasse au restant du dispositif de distribution. Ce manchon de raccord comprend un clapet d'entrée d'air et/ou un clapet anti retour.One principle of the invention is to group the outgoing air flow and / or entering the flush at a single opening provided with a connecting sleeve for connecting the flush to the remainder of the dispensing device. This coupling sleeve comprises an air inlet valve and / or an anti-return valve.

L'invention sera maintenant plus amplement décrite en référence aux dessins joints donnant à titre d'exemple non limitatif plusieurs modes de réalisation de l'invention.The invention will now be further described with reference to the accompanying drawings giving by way of non-limiting example several embodiments of the invention.

Le dispositif de distribution de produit fluide de l'invention représenté sur la figure 1 comprend essentiellement quatre éléments constitutifs, à savoir un corps 2, une tête 3, une chasse d'air 4 et un manchon de raccord 5. Le dispositif peut en outre comprendre d'autres éléments constitutifs optionnels ou accessoires, tels qu'une frette d'habillage 22, un joint de col 25 et/ou une capsule d'habillage 34.The fluid dispenser device of the invention shown in FIG. figure 1 comprises essentially four constituent elements, namely a body 2, a head 3, an air flush 4 and a coupling sleeve 5. The device may further comprise other optional or accessory components, such as a ferrule covering 22, a neck seal 25 and / or a covering cap 34.

Le dispositif de distribution est destiné à être monté sur un col 11 d'un réservoir 1 contenant le produit fluide à distribuer. Il peut typiquement s'agir d'un parfum ou d'un produit cosmétique pulvérisable. Le réservoir 1 peut être réalisé avec n'importe quel type de matériau approprié et présenter une certaine rigidité. Le col 11 fait typiquement saillie vers le haut de manière à définir un bord annulaire supérieur 13. Le col 11 peut également former un renfort annulaire externe 12 qui va servir à l'accrochage du dispositif de distribution de l'invention. Il s'agit là de caractéristiques tout à fait conventionnelles pour un réservoir de produit fluide dans les domaines de la parfumerie et/ou de la cosmétique.The dispensing device is intended to be mounted on a neck 11 of a tank 1 containing the fluid product to be dispensed. It can typically be a perfume or a sprayable cosmetic product. The tank 1 can be made with any type of suitable material and have a certain rigidity. The neck 11 typically protrudes upwardly so as to define an upper annular edge 13. The neck 11 may also form an outer annular reinforcement 12 which will serve to attach the dispensing device of the invention. These are quite conventional characteristics for a fluid reservoir in the fields of perfumery and / or cosmetics.

Le corps 2 du dispositif de distribution de l'invention comprend des moyens de fixation permettant de fixer le dispositif sur le col 11 du réservoir 1. Dans l'exemple utilisé pour illustrer la présente invention, le corps 2 comprend une jupe 21 apte à venir s'accrocher sous le renfort annulaire 12 du col 11. L'engagement de la jupe 21 sous le renfort 12 permet en outre d'écraser le joint de col 25 sur le bord supérieur 13 du col. Pour assurer une fixation stable de la jupe 21 autour du col 11, il peut être prévu une frette d'habillage 22 qui entoure la jupe 21 de l'extérieur et qui masque le corps 2 au moins partiellement. La frette d'habillage 22 est de préférence réalisée en métal.The body 2 of the dispensing device of the invention comprises fixing means for fixing the device on the neck 11 of the tank 1. In the example used to illustrate the present invention, the body 2 comprises a skirt 21 adapted to come cling under the annular reinforcement 12 of the neck 11. The engagement of the skirt 21 under the reinforcement 12 further allows to crush the neck seal 25 on the upper edge 13 of the neck. To ensure a stable attachment of the skirt 21 around the neck 11, there may be provided a trim ring 22 which surrounds the skirt 21 from the outside and which masks the body 2 at least partially. The trim band 22 is preferably made of metal.

Le corps 2 forme également une tubulure d'entrée 23 dans laquelle est emmanchée l'extrémité supérieure d'un tube plongeur 24 qui s'étend à l'intérieur du réservoir 1 jusqu'à proximité de son fond (non représenté). La tubulure 23 se prolonge en aval de l'extrémité du tube plongeur 24 de manière à former une première partie 25 d'un canal de produit fluide. Le corps 2 forme encore d'autres éléments, qui ne sont cependant pas critiques pour la présente invention.The body 2 also forms an inlet pipe 23 in which is fitted the upper end of a dip tube 24 which extends inside the tank 1 to near its bottom (not shown). The tubing 23 extends downstream of the end of the plunger tube 24 so as to form a first portion 25 of a fluid channel. The body 2 still forms other elements, which are not however critical for the present invention.

La tête 3 est montée sur le corps 2 de manière à prolonger la première partie de canal 25 sous la forme d'une seconde partie de canal 33 qui communique avec un orifice de distribution 31 au niveau duquel le produit fluide et l'air seront mélangés comme on le verra ci-après. La tête 3 peut être montée fixement sur le corps 2 : en variante, la tête 3 peut être montée avec une possibilité de déplacement axial et/ou rotatif par rapport au corps 2 pour par exemple réaliser une fonction d'obturation du canal de produit fluide 25, 33. Ce déplacement relatif de la tête 3 par rapport au corps 2 peut également être utilisé pour réaliser une fonction d'obturation d'un passage d'évent (non représenté) permettant de faire pénétrer de l'air extérieur à l'intérieur du réservoir 1 à mesure que du produit fluide en est extrait à travers le dispositif de distribution de l'invention.The head 3 is mounted on the body 2 so as to extend the first channel portion 25 in the form of a second channel portion 33 which communicates with a dispensing orifice 31 at which the fluid and the air will be mixed. as will be seen below. The head 3 can be fixedly mounted on the body 2: alternatively, the head 3 can be mounted with a possibility of axial displacement and / or rotational relative to the body 2 for example to perform a shutter function of the fluid product channel 25, 33. This relative displacement of the head 3 with respect to the body 2 can also be used to perform a shutter function of a vent passage (not shown) for introducing outside air to the interior of the tank 1 as the fluid product is extracted through the dispensing device of the invention.

La tête 3 forme également une partie de conduit d'air 32 présentant une extrémité aval qui communique directement avec l'orifice de distribution 31. Ainsi, le produit fluide provenant du canal 25, 33 et l'air sous pression provenant du conduit 32 se mélangent au niveau de l'orifice 31, et ce mélange est expulsé sous la pression de l'air sous la forme de fines gouttelettes de produit fluide. Optionnellement, la tête 3 peut être pourvue d'une capsule d'habillage 34, qui peut avantageusement être réalisée en métal. La capsule d'habillage 34 est pourvue d'un trou au niveau de l'orifice de distribution 31. De manière diamétralement opposée, la capsule 34 présente un autre trou permettant l'insertion du manchon de raccord 5, comme on le verra ci-après. A cet effet, la partie de conduit d'air 32 est formée à son extrémité amont avec un logement de raccordement 35 pour le manchon de raccord 5.The head 3 also forms an air duct portion 32 having a downstream end which communicates directly with the dispensing orifice 31. Thus, the fluid product coming from the channel 25, 33 and the air under pressure from the conduit 32 are mixed at the orifice 31, and this mixture is expelled under the pressure of air in the form of fine droplets of fluid. Optionally, the head 3 may be provided with a covering cap 34, which may advantageously be made of metal. The covering cap 34 is provided with a hole at the dispensing orifice 31. In a diametrically opposed manner, the cap 34 has another hole for the insertion of the connecting sleeve 5, as will be seen hereinafter. after. For this purpose, the air duct portion 32 is formed at its upstream end with a connection housing 35 for the connecting sleeve 5.

La chasse d'air 4 comprend une enveloppe 41 qui est réalisée avec un matériau élastique possédant une mémoire de forme. L'enveloppe 41 peut de manière classique présenter une forme de poire ou d'oeuf. Selon l'invention, l'enveloppe 41 comprend une ouverture unique 43 qui est délimitée par un bord 42, avantageusement renforcé. L'enveloppe 41 est apte à subir les phases répétées d'écrasement élastiques et de détente élastique. Lors des phases d'écrasement, l'air contenu à l'intérieur de l'enveloppe 41 est mis sous pression et refoulé à travers son ouverture 43. Lors des phases de détente élastique, de l'air extérieur pénètre à l'intérieur de l'enveloppe 41 à travers son ouverture unique 43.The air flush 4 comprises an envelope 41 which is made of an elastic material having a shape memory. The envelope 41 may conventionally have a pear or egg shape. According to the invention, the envelope 41 comprises a single opening 43 which is delimited by an edge 42, advantageously reinforced. The envelope 41 is able to undergo the repeated phases of elastic crushing and elastic expansion. During the crushing phases, the air contained inside the casing 41 is pressurized and discharged through its opening 43. During the elastic expansion phases, outside air enters the inside of the casing 41. the envelope 41 through its single opening 43.

Le manchon de raccord 5 est monté dans l'ouverture 43 de l'enveloppe 41, et est de préférence définitivement solidaire de l'enveloppe. Le manchon 5 obture partiellement l'ouverture 43 en définissant cependant une ou plusieurs parties de conduit d'air sortant 51, 52, ainsi qu'un passage d'air entrant 53. Ce passage 53 est pourvu d'un clapet d'entrée d'air 56 apte à laisser entrer de l'air extérieur dans la chasse d'air 4 lors des phases de détente élastique et à empêcher la sortie d'air de la chasse d'air à travers ce passage 53 lors des phases d'écrasement élastique. Pour son raccordement à la tête 3, le manchon 5 comprend un embout d'emmanchage 55 adapté à venir s'emmancher de manière étanche à l'intérieur du logement de raccordement 35 formé par la tête 3. Ainsi, la partie de conduit d'air 51, 52 formée par le manchon 5 peut communiquer directement avec la partie de conduit 32 formée par la tête 3. En écrasant l'enveloppe 41, l'air qu'elle contient est chassé à travers les parties de conduit d'air 51, 52 et 32 pour parvenir jusqu'à l'orifice de distribution 31 où cet air sous pression est mélangé avec le produit fluide en provenance du canal 25, 33. Lors des phases de détente élastique, de l'air extérieur peut pénétrer à l'intérieur de la chasse 4 à travers le passage 53 dont le clapet d'entrée d'air 56 s'ouvre du fait de la dépression générée à l'intérieur de la chasse. La partie de conduit d'air 51, 52 peut avantageusement être pourvue d'un clapet anti retour 58, comme on va maintenant le voir en référence aux figures 2a et 2b. Ces figures 2a et 2b montrent de manière agrandie les détails de réalisation du manchon de raccord 5 utilisé dans le premier mode de réalisation de la figure 1. La figure 2a montre le manchon lors d'une phase d'écrasement élastique, alors que la figure 2b montre ce même manchon 5 lors d'une phase de détente élastique. Les flux d'air sortant et entrant sont représentés par des flèches sur les figures. Le manchon de raccord 5 comprend un corps de base 5a auquel est associée une pièce de clapet 5b.The coupling sleeve 5 is mounted in the opening 43 of the casing 41, and is preferably permanently secured to the casing. The sleeve 5 partially closes the opening 43, however, defining one or more outgoing air duct portions 51, 52, as well as an inward air passage 53. This passage 53 is provided with an inlet flap. air 56 able to let outside air into the air flush 4 during the elastic expansion phases and to prevent the air outlet of the flush of air through this passage 53 during crushing phases elastic. For its connection to the head 3, the sleeve 5 comprises a plug-in connector 55 adapted to come and leak tightly inside the connection housing 35 formed by the head 3. Thus, the conduit portion of 51, 52 formed by the sleeve 5 can communicate directly with the part of conduit 32 formed by the head 3. By crushing the envelope 41, the air it contains is driven through the air duct portions 51, 52 and 32 to reach the dispensing orifice 31 where this pressurized air is mixed with the fluid product from the channel 25, 33. During the elastic expansion phases, outside air can enter the interior of the flush 4 through the passage 53, the flap of which air inlet 56 opens due to the depression generated inside the hunt. The air duct portion 51, 52 may advantageously be provided with an anti-return valve 58, as will now be seen with reference to the Figures 2a and 2b . These Figures 2a and 2b show in enlarged detail the details of embodiment of the coupling sleeve 5 used in the first embodiment of the figure 1 . The figure 2a shows the sleeve during a phase of elastic crushing, while the figure 2b shows the same sleeve 5 during an elastic expansion phase. The outgoing and incoming air flows are represented by arrows in the figures. The coupling sleeve 5 comprises a base body 5a which is associated with a valve member 5b.

Le corps de base 5a peut être réalisé de manière monobloc à partir d'un matériau plastique approprié qui présente une certaine rigidité. Ce corps de base 5a comprend une douille externe 54 qui est engagée de manière étanche à l'intérieur de l'ouverture 43 de l'enveloppe 41. La fixation et/ou l'étanchéité entre l'enveloppe 41 et la douille 54 peuvent être obtenues par n'importe quel moyen approprié, tels que par fixation serrante, encliquetage, harponnage, collage, soudage, surmoulage, bi injection, etc. Cette douille externe 54 comprend intérieurement une douille interne 54b qui s'étend de manière concentrique et coaxiale à l'intérieur de la douille externe 54. Cette douille externe 54b va servir de support pour la pièce de clapet 5b, comme on le verra ci-après. Selon l'invention, un passage d'air 53 est formé entre les douilles externe 54 et interne 54a. A son extrémité aval, le passage d'air entrant 53 comprend un siège de clapet 54a formé par la douille externe 54. D'autre part, la douille interne 54b se prolonge pour former l'embout de raccordement 55 définissant intérieurement une partie 52 du conduit d'air sous pression.The base body 5a can be made integrally from a suitable plastic material which has a certain rigidity. This base body 5a comprises an outer sleeve 54 which is sealingly engaged inside the opening 43 of the casing 41. The fixing and / or sealing between the casing 41 and the sleeve 54 may be obtained by any suitable means, such as by tightening fastening, snapping, spearing, gluing, welding, overmolding, bi injection, etc. This outer sleeve 54 internally comprises an inner sleeve 54b which extends concentrically and coaxially inside the outer sleeve 54. This outer sleeve 54b will serve as a support for the valve member 5b, as will be seen hereinafter after. According to the invention, an air passage 53 is formed between the outer bushings 54 and inner 54a. At its downstream end, the incoming air passage 53 comprises a valve seat 54a formed by the outer sleeve 54. On the other hand, the inner sleeve 54b is extended to form the connection endpiece 55 internally defining a portion 52 of the pressurized air duct.

La pièce de clapet 5b comprend, dans cet exemple de réalisation, une section de fixation 57 qui présente une configuration sensiblement cylindrique. Cette section de fixation 57 est engagée, par exemple par serrage, à l'intérieur de la douille externe 54b. Cette section de fixation 57 est creuse et définit intérieurement une partie 51 du conduit d'air sous pression. A une de ces extrémités, la section de fixation 57 forme un dôme souple 58a pourvu d'une fente auto jointante 58. Une fente auto jointante est une fente dont les bords sont jointifs et étanches en condition de repos. En revanche, ces bords vont se séparer de manière à définir une ouverture lorsqu'ils sont soumis à une pression suffisante. La fente 58 permet de séparer les deux parties de conduit d'air 51, 52. En d'autres termes, lorsque la fente est fermée ou jointante, la partie 51 ne peut pas communiquer avec la partie 52. Le dôme 58a est disposé de telle sorte que sa fente 58 ne s'ouvre que lorsque de l'air sous pression provient de la partie 51. Lorsque de l'air sous pression provient de la partie 52, la fente 58 reste fermée de manière étanche. Ainsi, cette fente 58 constitue un clapet anti retour, en ce sens qu'elle interdit toute entrée d'air à l'intérieur de la chasse 4 lors des phases de détente élastique. Ceci est illustré sur la figure 2b. En revanche, la fente 58 va largement s'ouvrir pour laisser passer l'air de la chasse lors des phases d'écrasement élastique. Ceci est illustré sur la figure 2a. La pièce de clapet 5b forme également un clapet d'entrée d'air 56 sous la forme d'une membrane annulaire qui s'étend vers l'extérieur à partir d'une extrémité de la section de fixation 57, qui est opposée à celle du dôme 58a. La périphérie externe libre 56a de la membrane repose sélectivement de manière étanche sur le siège 54a formé par la douille externe 54. La membrane 56 obture ainsi l'extrémité aval du passage d'air 53. Du fait de sa disposition à l'intérieur de la chasse 4, le clapet d'entrée d'air 56 est plaqué sur son siège 54a lors des phases d'écrasement élastique (figure 2a), et décollé de son siège lors des phases de détente élastique (figure 2b), pour laisser pénétrer de l'air extérieur dans la chasse à travers le passage d'air 53.The valve member 5b comprises, in this embodiment, a securing section 57 which has a substantially cylindrical configuration. This fixing section 57 is engaged, for example by clamping, inside the outer sleeve 54b. This fixing section 57 is hollow and internally defines a portion 51 of the air duct under pressure. At one of these ends, the securing section 57 forms a flexible dome 58a provided with a self-sealing slot 58. A self-sealing slot is a slot whose edges are contiguous and tight in rest condition. On the other hand, these edges will separate so as to define an opening when they are subjected to a sufficient pressure. The slot 58 separates the two air duct portions 51, 52. In other words, when the slot is closed or sealant, the portion 51 can not communicate with the portion 52. The dome 58a is disposed of so that its slot 58 opens only when pressurized air comes from the part 51. When pressurized air comes from the part 52, the slot 58 remains sealed. Thus, this slot 58 constitutes a check valve, in that it prohibits any air intake inside the flush 4 during elastic expansion phases. This is illustrated on the figure 2b . In contrast, the slot 58 will open wide to let the air of the hunting during phases of elastic crushing. This is illustrated on the figure 2a . The valve member 5b also forms an air inlet valve 56 in the form of an annular membrane which extends outwardly from one end of the attachment section 57, which is opposite to that of the dome 58a. The free external periphery 56a of the membrane selectively rests in a sealed manner on the seat 54a formed by the outer sleeve 54. The membrane 56 thus closes the downstream end of the air passage 53. Because of its arrangement inside the the flush 4, the air inlet valve 56 is pressed onto its seat 54a during the phases of elastic crushing ( figure 2a ), and detached from its seat during the phases of elastic relaxation ( figure 2b ), to allow outside air to enter the flush through the air passage 53.

Il faut également noter que le clapet d'entrée d'air 56 est formé autour de la partie de conduit d'air 51 et est donc soumis à la pression générée par le flux d'air, de manière à plaquer sa périphérie externe 56a de manière étanche sur son siège 54a. Ainsi, on se sert du flux d'air sous pression généré par la chasse pour assurer une parfaite étanchéité du clapet d'entrée d'air lors des phases d'écrasement élastique. En revanche, lors des phases de détente élastique, la fente auto jointante 58 est maintenue fermée par la dépression régnant à l'intérieur de la chasse, et l'air extérieur est ainsi aspiré à travers le passage d'air 53 jusque dans la chasse en forçant le clapet d'entrée d'air 56 en position ouverte.It should also be noted that the air inlet valve 56 is formed around the air duct portion 51 and is therefore subjected to the pressure generated by the air flow, so as to press its outer periphery 56a tightly on its seat 54a. Thus, the pressurized air flow generated by the flush is used to ensure a perfect seal of the air inlet valve during elastic crushing phases. On the other hand, during the phases of elastic expansion, the self-sealing slot 58 is kept closed by the depression prevailing inside the flush, and the outside air is thus sucked through the air passage 53 into the flush forcing the air inlet valve 56 to the open position.

A la place du clapet à membrane 56, on peut aussi utiliser un clapet à volet comprenant un ou plusieurs volets adaptés à obturer des trous de passage correspondants. Ces volets peuvent être découpés dans une bride annulaire sensiblement rigide ayant la forme de la membrane 56.Instead of the membrane valve 56, it is also possible to use a flap valve comprising one or more flaps adapted to close corresponding through holes. These flaps can be cut in a substantially rigid annular flange having the shape of the membrane 56.

On peut également remarquer que la pièce de clapet 5b peut être réalisée de manière monobloc avec une seule matière plastique : les caractéristiques de rigidité et de déformabilité étant uniquement assurées par des variations d'épaisseur de paroi. En effet, on peut remarquer sur les figures 2a et 2b que la section de fixation 57 présente une épaisseur de paroi bien supérieure à celle du dôme 58a ou de la membrane 56. En variante représentée sur la figure 3, la pièce de clapet 5b peut être réalisée avec une section de fixation 57 formée de deux parties 57' et 57" qui peuvent avantageusement être surmoulées ou bi injectées. La partie 57' peut être réalisée en un matériau plastique souple, alors que la pièce 57" est réalisée avec un matériau plastique rigide conférant à l'ensemble la rigidité suffisante pour assurer une fixation stable de la pièce de clapet 5b dans la douille interne 54b.It can also be noted that the valve member 5b can be made integrally with a single plastic material: the rigidity and deformability characteristics being solely provided by wall thickness variations. Indeed, we can notice on Figures 2a and 2b that the securing section 57 has a wall thickness much greater than that of the dome 58a or the membrane 56. As a variant shown in FIG. figure 3 the valve member 5b can be made with an attachment section 57 formed of two parts 57 'and 57 "which can advantageously be overmolded or bi-injected, the part 57' can be made of a flexible plastic material, whereas the part 57 "is made of a rigid plastic material giving the assembly sufficient rigidity to ensure a stable attachment of the valve member 5b in the inner sleeve 54b.

En se référant aux figures 4a et 4b, il est représenté un manchon de raccord 5 selon un second mode de réalisation de l'invention. Ce manchon comprend également un corps de base 5a ainsi qu'une pièce de clapet 5b. Toute comme dans le mode réalisation précédent, le manchon de raccord 5 est monté de manière fixe et étanche, et avantageusement définitive, dans l'ouverture 43 de la chasse d'air 4. Pour cela, le manchon 5 comprend une douille externe 54 qui peut avantageusement être pourvue de crans d'accrochage sous la forme de harpons. Le corps de base 5a forme également un embout de raccordement 55 destiné à être inséré dans le logement correspondant 35 de la tête. Cet embout 55 forme intérieurement une partie de conduit d'air 52. La pièce de clapet 5b est montée à l'intérieur de la douille externe 54. Pour cela, la pièce de clapet 5b comprend une bague 59 qui forme deux sièges de clapet 590 et 591. D'autre part, la pièce de clapet 5b comprend un organe mobile de clapet 57b qui forme un clapet d'entrée d'air 56b ainsi qu'un clapet anti retour 58b. Le clapet 56b est destiné à venir sélectivement en appui étanche sur le siège 591, alors que le clapet 58b est destiné à venir sélectivement en appui étanche sur le siège 590. Le clapet d'entrée d'air 56b se présente sous la forme d'une corolle sensiblement tronconique, alors que le clapet anti retour 58b se présente sous la forme d'un disque légèrement concave. Les deux clapets 56b et 58b sont reliés ensemble par une tige de liaison 568, de sorte que les deux clapets sont solidaires l'un de l'autre en déplacement. Plus précisément, l'organe mobile de clapet 57 est déplaçable selon un axe unique qui est imposé par la structure de la bague 59. Ainsi, seul un clapet à la fois peut reposer de manière étanche sur son siège. Sur la figure 4a, c'est le clapet 56b qui repose de manière étanche sur son siège 591, alors que sur la figure 4b c'est le clapet 58b qui repose sur son siège 590. La configuration de la figure 4a correspond à une phase d'écrasement élastique, au cours de laquelle l'air contenu dans la chasse d'air est mis sous pression et refoulé à travers le manchon de raccord 5. Le trajet de l'air est représenté par la ligne qui se termine par une flèche. On peut alors remarquer que le clapet 56b est fermé. La figure 4b correspond à une phase de détente élastique, au cours de laquelle de l'air extérieur peut pénétrer à l'intérieur de la chasse d'air à travers le passage d'entrée d'air 53 qui est ouvert, du fait que le clapet 56b est décollé de son siège 591. Le passage d'entrée d'air 53 se présente sous la forme de plusieurs ports latéraux formés par la bague 59. Ces ports latéraux se rejoignent au niveau d'un passage central dans lequel s'étend la tige de liaison 57b.Referring to Figures 4a and 4b , there is shown a coupling sleeve 5 according to a second embodiment of the invention. This sleeve also comprises a base body 5a and a valve member 5b. As in the previous embodiment, the coupling sleeve 5 is fixedly mounted and sealed, and advantageously permanently, in the opening 43 of the air flushing 4. For this, the sleeve 5 comprises an outer sleeve 54 which can advantageously be provided with notches hanging in the form of harpoons. The base body 5a also forms a connecting end 55 intended to be inserted into the corresponding housing 35 of the head. This nozzle 55 internally forms an air duct portion 52. The valve member 5b is mounted inside the outer sleeve 54. For this, the valve member 5b comprises a ring 59 which forms two valve seats 590 and 591. On the other hand, the valve member 5b includes a movable valve member 57b which forms an air inlet valve 56b and a check valve 58b. The valve 56b is intended to come selectively in tight abutment on the seat 591, while the valve 58b is intended to come selectively in tight abutment on the seat 590. The air inlet valve 56b is in the form of a substantially frustoconical corolla, while the nonreturn valve 58b is in the form of a slightly concave disk. The two valves 56b and 58b are connected together by a connecting rod 568, so that the two valves are integral with each other in displacement. Specifically, the movable valve member 57 is movable along a single axis which is imposed by the structure of the ring 59. Thus, only one valve at a time can stand tightly on its seat. On the figure 4a it is the valve 56b that sits tightly on its seat 591, whereas on the figure 4b it is the valve 58b which rests on its seat 590. The configuration of the figure 4a corresponds to a phase of elastic crushing, during which the air contained in the flush of air is pressurized and discharged through the connecting sleeve 5. The air path is represented by the line which is ends with an arrow. It can then be noted that the valve 56b is closed. The figure 4b corresponds to an elastic expansion phase, during which outside air can penetrate inside the air flush through the air inlet passage 53 which is open, because the valve 56b The air intake passage 53 is in the form of several lateral ports formed by the ring 59. These lateral ports meet at a central passage in which the rod extends. link 57b.

Dans ce second mode de réalisation, on a vu que les deux clapets 58b et 56b sont solidaires l'un de l'autre en déplacement. Ils pourraient théoriquement être réalisés de manière monobloc, mais pour des raisons de montage pratique, ils sont réalisés en deux pièces. En effet, le disque 58b faisant office de clapet peut être moulé de manière monobloc avec la tige de liaison 57b. Le clapet d'entrée d'air 56b peut être réalisé sous la forme d'un capuchon formé avec une corolle servant de clapet. Ce capuchon peut être monté par serrage sur l'extrémité libre de la tige de liaison 57b.In this second embodiment, it has been seen that the two valves 58b and 56b are integral with each other in displacement. They could theoretically be made in one piece, but for reasons of practical assembly, they are made in two pieces. Indeed, the disk 58b acting valve can be molded integrally with the connecting rod 57b. The air inlet valve 56b can be made in the form of a cap formed with a flap serving as a valve. This cap can be mounted by clamping on the free end of the connecting rod 57b.

Comme on l'a vu, le fonctionnement de ce manchon à double clapet est identique à celui du premier mode réalisation. La seule différence est que les deux clapets sont couplés mécaniquement en déplacement.As we have seen, the operation of this double-valve sleeve is identical to that of the first embodiment. The only difference is that the two valves are mechanically coupled in displacement.

En se référant à la figure 5, on voit un troisième mode de réalisation pour un manchon de raccord 5. Celui-ci comprend également un corps de base 5a associé à une pièce de clapet 5b. Cette pièce de clapet 5b forme le passage d'entrée d'air 53, ainsi que deux sièges de clapet 561 et 581. Le clapet d'entrée d'air 56c est ici formé par une bille adaptée à reposer sélectivement de manière étanche sur son siège 561. Le clapet anti retour 58c se présente sous la forme d'un disque destiné à reposer sélectivement de manière étanche sur son siège 581. Le fonctionnement de ce manchon à double clapet est identique à ceux des modes de réalisation précédents. Toutefois, dans ce mode de réalisation les deux clapets 56c et 58c sont totalement découplés, puisqu'il n'y a aucune liaison entre eux.Referring to the figure 5 , we see a third embodiment for a connecting sleeve 5. This also comprises a base body 5a associated with a valve member 5b. This valve part 5b forms the air inlet passage 53, as well as two valve seats 561 and 581. The air inlet valve 56c is here formed by a ball adapted to selectively rest on a watertight manner. seat 561. The non-return valve 58c is in the form of a disc for selectively resting sealingly on its seat 581. The operation of this double-valve sleeve is identical to those of the previous embodiments. However, in this embodiment the two valves 56c and 58c are completely decoupled, since there is no connection between them.

La figure 6 montre un quatrième mode de réalisation pour un manchon de raccord 5 selon l'invention. Ce manchon comprend également un corps de base 5a associé à une pièce de clapet 5b. La pièce de clapet 5b forme une section de fixation 57 qui se termine d'un côté par un siège de clapet 571 et de l'autre côté par une bride annulaire souple 56d adaptée à reposer de manière étanche sélectivement sur un siège 541 formé par la douille externe 54 du corps de base 5a. Le passage d'entrée d'air 53 est formé à la manière du premier mode de réalisation, c'est-à-dire entre la douille externe 54 et une douille interne 54b recevant à l'intérieur la pièce de clapet 5b. Le clapet anti retour 58d se présente ici sous la forme d'une bille reposant sélectivement de manière étanche sur le siège 571. Le clapet d'entrée d'air 56d est formé par la bride souple annulaire. La figure 6 été représentée au cours d'une phase de détente élastique, l'air extérieur étant aspiré à travers le passage d'air 53 jusqu'à l'intérieur de la chasse avec le clapet d'entrée d'air ouvert.The figure 6 shows a fourth embodiment for a coupling sleeve 5 according to the invention. This sleeve also comprises a base body 5a associated with a valve member 5b. The valve member 5b forms a securing section 57 which terminates on one side by a valve seat 571 and on the other side by a flexible annular flange 56d adapted to selectively sealably rest on a seat 541 formed by the outer sleeve 54 of the basic body 5a. The air inlet passage 53 is formed in the manner of the first embodiment, that is to say between the outer sleeve 54 and an inner sleeve 54b receiving inside the valve member 5b. The check valve 58d is here in the form of a ball selectively sealingly resting on the seat 571. The air inlet valve 56d is formed by the annular flexible flange. The figure 6 was shown during an elastic expansion phase, the outside air being sucked through the air passage 53 to the inside of the flush with the open air inlet valve.

Dans ce mode réalisation, le siège du clapet anti retour 571 est réalisé de manière monobloc avec le clapet d'entrée d'air 56d.In this embodiment, the seat of the non-return valve 571 is made integrally with the air inlet valve 56d.

Dans tous les modes de réalisation représentés sur les figures, le manchon de raccord 5 comprend à la fois un clapet d'entrée d'air et un clapet anti retour. Toutefois, le manchon de raccord pourrait seulement comprendre un seul clapet, avantageusement le clapet d'entrée d'air.In all the embodiments shown in the figures, the coupling sleeve 5 comprises both an air inlet valve and a nonreturn valve. However, the coupling sleeve could only include a single valve, preferably the air inlet valve.

Grâce à l'invention, on dispose d'une chasse d'air à ouverture unique grâce à l'utilisation d'un manchon de raccord intégrant un ou deux clapets.Thanks to the invention, it has a single-opening air flush through the use of a coupling sleeve incorporating one or two valves.
