Description

L'invention concerne une pompe destinée à être montée sur un flacon de sorte à permettre la distribution d'un liquide contenu dans ledit flacon, ainsi qu'un flacon contenant un produit liquide sur lequel une telle pompe est montée.The invention relates to a pump intended to be mounted on a bottle so as to allow the dispensing of a liquid contained in said bottle, and a bottle containing a liquid product on which such a pump is mounted.

Dans une application particulière, le liquide est de type gel ou crème, par exemple pour une utilisation en cosmétique ou pour des traitements pharmaceutiques.In a particular application, the liquid is of the gel or cream type, for example for use in cosmetics or for pharmaceutical treatments.

On connaît des pompes présentant les propriétés suivantes :

  • fermeture étanche de l'orifice d'éjection afin de limiter les contacts entre l'air extérieur et le liquide stationnant dans la pompe, notamment pour éviter un dessèchement et/ou une dégradation dudit liquide dans le temps ;
  • absence de contact entre le liquide et des pièces métalliques, afin d'éviter d'éventuelles dégradations physico-chimiques du liquide ;
  • absence de passage pour la reprise d'air dans le flacon en compensation du produit restitué.
Pumps having the following properties are known:
  • sealing the ejection orifice in order to limit the contacts between the outside air and the liquid stationing in the pump, in particular to prevent drying out and / or degradation of said liquid with time;
  • absence of contact between the liquid and metal parts, in order to avoid any physico-chemical degradation of the liquid;
  • no passage for the return of air in the bottle in compensation for the returned product.

L'invention vise à simplifier la réalisation de telles pompes en proposant une conception constituée de pièces simples à réaliser et en nombre limité.The invention aims to simplify the production of such pumps by proposing a design consisting of simple parts to achieve and limited number.

En outre, la pompe selon l'invention propose une étanchéité de la fermeture qui est améliorée de sorte à pouvoir distribuer des liquides dont la sensibilité à l'air est importante. Par conséquent, l'utilisation combinée d'une pompe selon l'invention avec un flacon contenant un liquide sensible à l'air est particulièrement avantageuse.In addition, the pump according to the invention provides a sealing of the closure which is improved so as to be able to dispense liquids whose sensitivity to air is important. Therefore, the combined use of a pump according to the invention with a bottle containing an air sensitive liquid is particularly advantageous.

En particulier, par sensible à l'air, on prévoit des liquides contenant un solvant susceptible de s'évaporer rapidement, par exemple à base d'alcool ou d'eau, ou contenant des substances photosensibles, par exemple des filtres solaires, ou facilement oxydables, par exemple des vitamines notamment de la vitamine C.In particular, by sensitive to air, there is provided liquids containing a solvent which can evaporate rapidly, for example based on alcohol or water, or containing photosensitive substances, for example sunscreens, or easily oxidizable, for example vitamins including vitamin C.

Par ailleurs, le fonctionnement de la pompe selon l'invention limite la mise en pression du liquide lors de la distribution. Ainsi, l'utilisation combinée d'une pompe selon l'invention avec un flacon contenant un liquide sensible aux contraintes mécaniques est également particulièrement avantageuse.Furthermore, the operation of the pump according to the invention limits the pressure setting of the liquid during dispensing. Thus, the combined use of a pump according to the invention with a bottle containing a liquid sensitive to mechanical stresses is also particularly advantageous.

En particulier, par sensible aux contraintes mécaniques, on prévoit des liquides, par exemple des crèmes, susceptibles de subir une transformation physico-chimiques sous pression, notamment une séparation ou un changement de phase.In particular, sensitive to mechanical stresses, there are provided liquids, for example creams, capable of undergoing physico-chemical transformation under pressure, in particular a separation or a phase change.

Le fonctionnement de la pompe selon l'invention permet également la distribution de liquides particulièrement visqueux.The operation of the pump according to the invention also allows the dispensing of particularly viscous liquids.

  • un organe d'actionnement solidaire du dispositif de déplacement du pointeau et monté coulissant dans le piston doseur, ledit montage en coulissement étant agencé, par appui sur le bouton poussoir, pour actionner le dispositif de déplacement et pour disposer le clapet en position de fermeture de sorte à permettre l'éjection du liquide depuis la chambre de dosage.
To achieve these different improvements of the pumps according to the prior art, according to a first aspect, the invention provides a pump intended to be mounted on a bottle so as to allow the distribution of a liquid contained in said bottle, said pump comprising:
  • a hoop intended to be secured to the bottle, said hoop comprising a communication port with the liquid;
  • a push button comprising a liquid ejection orifice, said push button being mounted on said hoop in translation constrained by an elastic return means;
  • a metering sleeve mounted in said push button, said sleeve incorporating a closure needle of the ejection orifice and a reversible displacement device of said needle between a closed position and an ejection position;

Selon un deuxième aspect, l'invention propose un flacon contenant un produit liquide, ledit flacon comprenant une bague sur laquelle la frette d'une telle pompe est montée avec l'orifice en communication avec le liquide.According to a second aspect, the invention proposes a bottle containing a liquid product, said bottle comprising a ring on which the hoop of such a pump is mounted with the orifice in communication with the liquid.

D'autres objets et avantages de l'invention apparaîtront dans la description qui suit faite en référence aux figures 1 à 6 annexées qui sont des vues en coupe longitudinale d'un flacon équipé d'une pompe selon un mode de réalisation de l'invention, dans les différentes positions d'utilisation suivantes : au repos (figure 1), en position d'éjection du liquide (figures 2-4), en position d'aspiration du liquide (figure 5) et en position après utilisation (figure 6).Other objects and advantages of the invention will appear in the following description made with reference to Figures 1 to 6 appended which are views in longitudinal section of a bottle equipped with a pump according to one embodiment of the invention, in the following different use positions: at rest ( figure 1 ), in the ejection position of the liquid ( Figures 2-4 ), in the suction position of the liquid ( figure 5 ) and in position after use ( figure 6 ).

Dans la description, les termes de positionnement dans l'espace sont pris en référence à la position de la pompe représentée sur les figures.In the description, the spatial positioning terms are taken with reference to the position of the pump shown in the figures.

En relation avec les figures, on décrit un mode de réalisation d'une pompe montée sur un flacon de sorte à permettre la distribution d'un liquide contenu dans ledit flacon. Dans un exemple d'application, le liquide est un gel ou une crème, pour un usage cosmétique ou pour des traitements pharmaceutiques.In connection with the figures, there is described an embodiment of a pump mounted on a bottle so as to allow the distribution of a liquid contained in said bottle. In an exemplary application, the liquid is a gel or a cream, for cosmetic use or for pharmaceutical treatments.

Le flacon comprend un corps 1 surmonté par une bague 2 sur laquelle la pompe est montée. En outre, un piston d'amené 3 du liquide est monté coulissant dans le corps 1 de sorte à pousser le liquide dans ladite pompe en vue de sa distribution sans reprise d'air. Pour ce faire, le flacon comprend, à l'opposé de la pompe, un trou d'évent 4. Bien que la description soit faite en relation avec une distribution sans reprise d'air, la pompe suivant l'invention peut être utilisée avec d'autres types de distribution.The bottle comprises a body 1 surmounted by a ring 2 on which the pump is mounted. In addition, a plunger 3 of the liquid is slidably mounted in the body 1 so as to push the liquid into said pump for distribution without air intake. To do this, the bottle comprises, opposite the pump, a vent hole 4. Although the description is made in connection with a distribution without air intake, the pump according to the invention can be used with other types of distribution.

La pompe comprend une frette 5 solidarisée dans la bague 2 du flacon, ladite frette comprenant un orifice 6 de mise en communication de la pompe avec le liquide contenu dans le corps 1. Plus précisément, la frette 5 est montée de façon étanche sur la bague 2 avec l'orifice 6 en communication avec le liquide.The pump comprises a hoop 5 secured in the ring 2 of the bottle, said hoop comprising an orifice 6 for placing the pump in communication with the liquid contained in the body 1. More specifically, the hoop 5 is sealingly mounted on the ring 2 with the orifice 6 in communication with the liquid.

La frette 5 peut être réalisée par moulage d'un matériau plastique, notamment en polypropylène, et comprend un fond dans lequel l'orifice 6 est formé axialement. Par ailleurs, la frette 5 présente une géométrie cylindrique de révolution et, depuis le fond, s'étendent de façon concentrique :

  • un manchon extérieur 7 dont une partie de la surface extérieure est emmanchée dans la bague 2 ;
  • un manchon intérieur 8 dont l'extrémité inférieure est pourvue d'une gorge 9 ; et
  • un manchon central 10 sur la paroi inférieure duquel l'orifice de distribution 6 est formé.
The hoop 5 can be made by molding a plastic material, in particular polypropylene, and comprises a bottom in which the orifice 6 is formed axially. Furthermore, the hoop 5 has a cylindrical geometry of revolution and, from the bottom, extend concentrically:
  • an outer sleeve 7, a portion of the outer surface is fitted in the ring 2;

Par ailleurs, dans le mode de réalisation représenté, le flacon comprend un capot 11 qui est monté sur l'extérieur du manchon extérieur 7, au dessus de la partie emmanchée dans la bague 2.Furthermore, in the embodiment shown, the bottle comprises a cover 11 which is mounted on the outside of the outer sleeve 7, above the portion fitted in the ring 2.

La pompe comprend un bouton poussoir 12 qui est pourvu d'un orifice d'éjection 13 du liquide, ledit bouton poussoir étant monté sur la frette 5 en translation contrainte par un moyen de rappel élastique formé d'un ressort 14. Plus précisément, le bouton poussoir comprend une jupe pourvue de l'orifice 13 pour une éjection sensiblement radiale. En outre, la jupe comprend un jonc annulaire 15 qui coopère, sur la course de translation, avec une gorge 16 formée sur le manchon extérieur 7.The pump comprises a push button 12 which is provided with an ejection orifice 13 of the liquid, said push button being mounted on the hoop 5 in translation constrained by an elastic return means formed of a spring 14. More specifically, the push button comprises a skirt provided with the orifice 13 for a substantially radial ejection. In addition, the skirt comprises an annular ring 15 which cooperates, on the translation stroke, with a groove 16 formed on the outer sleeve 7.

La pompe comprend également un manchon doseur 18 qui est monté dans le bouton poussoir 12 pour être solidaire de lui sur la course de translation. Le manchon 18 est entouré par une jupe extérieure 19 qui comprend un rebord annulaire 20 coopérant avec une rainure 21 formée dans la jupe du bouton poussoir 12, de sorte à former zone d'association étanche entre ledit manchon et ledit bouton poussoir.The pump also comprises a metering sleeve 18 which is mounted in the push button 12 to be secured to it on the translational stroke. The sleeve 18 is surrounded by an outer skirt 19 which comprises an annular flange 20 cooperating with a groove 21 formed in the skirt of the button pusher 12, so as to form sealed association zone between said sleeve and said push button.

Par ailleurs, la paroi radiale 22 de liaison entre la jupe 19 et le manchon 18 forme surface de butée du ressort 14, ledit ressort étant en outre disposé autour du manchon intérieur 8 de la frette 5.Furthermore, the radial wall 22 connecting the skirt 19 and the sleeve 18 forms a stop surface of the spring 14, said spring being furthermore disposed around the inner sleeve 8 of the hoop 5.

Le manchon doseur 18 intègre également, en une seule pièce par exemple réalisée par moulage, un pointeau d'obturation 23 de l'orifice d'éjection 13 et un dispositif de déplacement réversible dudit pointeau entre une position d'obturation et une position d'éjection. En particulier, le pointeau 23 est disposé dans le volume étanche formé dans la partie supérieure du bouton poussoir 12, et plus précisément sous la paroi supérieure dudit bouton poussoir. Pour permettre le passage du liquide vers l'orifice d'éjection 13, des orifices sont prévus sur la partie supérieure du manchon doseur 18.The metering sleeve 18 also integrates, in one piece, for example made by molding, a closure needle 23 of the ejection orifice 13 and a device for reversibly moving said needle between a closed position and a position of ejection.

Le piston 24 est monté en translation étanche dans la frette 5 entre une position d'ouverture et une position de fermeture de l'orifice 6 au moyen du clapet 26. Par ailleurs, le manchon doseur 18 et le piston 24 sont montés en translation étanche l'un par rapport à l'autre de sorte à définir entre eux une chambre de dosage du liquide.The piston 24 is mounted in sealed translation in the hoop 5 between an open position and a closed position of the orifice 6 by means of the valve 26. Moreover, the metering sleeve 18 and the piston 24 are mounted in sealed translation relative to each other so as to define between them a liquid dosing chamber.

Plus précisément, la paroi extérieure du piston doseur 24 est montée en coulissement étanche dans le manchon intérieur 8 par l'intermédiaire du manchon doseur 18. Pour ce faire, la paroi extérieure du piston doseur 24 comprend :

  • en partie inférieure, un jonc 27 qui coopère avec la gorge 9 formée dans le manchon intérieur 8, de sorte à définir la course du piston doseur 24 entre les positions d'ouverture et de fermeture du clapet 26 ;
  • en partie supérieure, une lèvre annulaire d'étanchéité 28 qui est en contact frottant sur la paroi intérieure du manchon doseur 18.
More specifically, the outer wall of the metering piston 24 is slidably mounted in the inner sleeve 8 via the metering sleeve 18. To do this, the outer wall of the metering piston 24 comprises:
  • in the lower part, a rod 27 which cooperates with the groove 9 formed in the inner sleeve 8, so as to define the stroke of the metering piston 24 between the open and closed positions of the valve 26;
  • in the upper part, an annular sealing lip 28 which is in rubbing contact on the inner wall of the metering sleeve 18.

Par ailleurs, le canal de distribution 25 est monté en coulissement étanche dans le manchon central 10. Le clapet 26 est formé d'un téton qui, en position de fermeture, vient s'engager de façon étanche dans l'orifice de distribution 6, ledit téton étant monté dans l'extrémité inférieure du canal 25 par l'intermédiaire de ponts de matière permettant le passage de liquide autour dudit téton en position d'ouverture. En outre, une lèvre annulaire d'étanchéité 29 est formée sur la paroi extérieure du canal 25, autour du téton, de sorte à venir en contact frottant sur la paroi intérieure du manchon central 10.Furthermore, the distribution channel 25 is mounted in leaktight sliding in the central sleeve 10. The valve 26 is formed of a nipple which, in the closed position, engages sealingly in the dispensing orifice 6, said nipple being mounted in the lower end of the channel 25 via material bridges allowing the passage of liquid around said nipple in the open position. In addition, an annular sealing lip 29 is formed on the outer wall of the channel 25, around the stud, so as to come into rubbing contact on the inner wall of the central sleeve 10.

La pompe comprend également un organe d'actionnement 30 qui est solidaire du dispositif de déplacement du pointeau 23 et monté coulissant dans le piston doseur 24. Le montage coulissant est agencé, par appui sur le bouton poussoir 12, pour actionner le dispositif de déplacement et pour disposer le clapet 26 en position de fermeture de sorte à permettre l'éjection du liquide depuis la chambre de dosage.The pump also comprises an actuating member 30 which is integral with the needle displacement device 23 and slidably mounted in the metering piston 24. The sliding assembly is arranged, by pressing the push button 12, to actuate the displacement device and for arranging the valve 26 in the closed position so as to allow ejection of the liquid from the metering chamber.

L'organe d'actionnement 30 est formé d'une tige qui est montée coulissante à l'intérieur du canal de distribution 25 avec une interférence suffisante pour actionner le pointeau 23 et le clapet 26. Pour ce faire, la tige est pourvue d'un jonc de coulissement 31 dans le canal 25, ledit jonc comprenant un rebord arrière qui coopère avec une butée radiale 32 prévue sur la périphérie du canal 25 de sorte à définir la fin de course supérieure dudit jonc à l'intérieur dudit canal. Par ailleurs, l'organe d'actionnement 30, et notamment le jonc 31, peut être réalisé en matériau plastique dont la dureté est supérieure à celle formant le piston 24, par exemple en polypropylène pour l'organe 30 et en polyéthylène pour le piston 24.The actuating member 30 is formed of a rod which is slidably mounted inside the distribution channel 25 with sufficient interference to actuate the needle 23 and the valve 26. To do this, the rod is provided with a sliding ring 31 in the channel 25, said ring comprising a rear flange which cooperates with a radial abutment 32 provided on the periphery of the channel 25 so as to define the upper limit of said ring within said channel. Furthermore, the actuating member 30, and in particular the rod 31, may be made of plastic material whose hardness is greater than that forming the piston 24, for example polypropylene for the member 30 and polyethylene for the piston 24.

En outre, l'organe d'actionnement 30 comprend des ailettes radiales 33 qui s'étendent à partir de la tige de sorte à former entre elles des passages axiaux de liquide au travers dudit organe.In addition, the actuating member 30 comprises radial fins 33 which extend from the rod so as to form axial fluid passages therebetween through said member.

Dans le mode de réalisation décrit, le pointeau 23 comprend un bras 34 dont l'extrémité avant est pourvue d'une tête d'obturation 35 qui vient s'engager de façon étanche dans l'orifice d'éjection 13. Par ailleurs, l'extrémité arrière du bras 34 est associée au manchon doseur 18 par l'intermédiaire du dispositif de déplacement.In the embodiment described, the needle 23 comprises an arm 34 whose front end is provided with a sealing head 35 which engages sealingly in the ejection orifice 13. the rear end of the arm 34 is associated with the metering sleeve 18 via the displacement device.

Le dispositif de déplacement du pointeau 23 comprend une collerette 36 associée à l'organe d'actionnement 30 et une biellette 37 agencée pour transformer un déplacement axial de l'organe d'actionnement 30 en translation du bras 34 relativement au bouton poussoir 12.The device for moving the needle 23 comprises a flange 36 associated with the actuating member 30 and a connecting rod 37 arranged to transform an axial displacement of the actuating member 30 in translation of the arm 34 relative to the pushbutton 12.

Pour ce faire, la biellette 37 est pourvue de trois articulations - interne, externe, supérieure - avec respectivement ladite collerette, l'intérieur du manchon doseur 18 et l'extrémité arrière du bras 34. En outre, la biellette 37 est élastiquement déformable entre les articulations interne et externe.To do this, the rod 37 is provided with three joints - internal, external, upper - with respectively said flange, the inside of the metering sleeve 18 and the rear end of the arm 34. In addition, the link 37 is elastically deformable between internal and external joints.

Par ailleurs, la biellette 37 comprend une paroi arrière 38 formée entre les articulations externe et supérieure et, dans le mode de réalisation représenté, la biellette 37 comprend un pont de matière 39 élastiquement déformable qui est incurvé pour relier la paroi arrière 38 à la collerette 36.Furthermore, the rod 37 comprises a rear wall 38 formed between the outer and upper hinges and, in the embodiment shown, the rod 37 comprises a bridge 39 of elastically deformable material which is curved to connect the rear wall 38 to the collar 36.

Le dispositif de déplacement du pointeau 23 comprend en outre un élément 40 élastiquement déformable qui est pourvu d'une articulation interne avec la collerette 36 et d'une articulation externe avec l'intérieur du manchon doseur 18. L'élément 40 élastiquement déformable est formé d'un pont de matière en U sur chaque extrémité duquel sont formées les articulations. Selon la réalisation représentée, les articulations sont réalisées par amincissement de matière.The needle displacement device 23 further comprises an elastically deformable element 40 which is provided with an internal articulation with the flange 36 and an external articulation with the inside of the metering sleeve 18. The elastically deformable element 40 is formed a bridge of U-shaped material on each end of which are formed the joints. According to the embodiment shown, the joints are made by thinning material.

L'élément 40 élastiquement déformable est prévu à l'opposé de la biellette 37 par rapport à l'axe du manchon doseur 18. Plus précisément, la collerette 36 présente une géométrie sensiblement rectangulaire dont chaque petit coté porte respectivement une articulation interne. La collerette 36 comprend également un orifice dans lequel la tête 41 de l'organe d'actionnement 30 est encliquetée.The elastically deformable element 40 is provided opposite to the link 37 with respect to the axis of the metering sleeve 18. More specifically, the collar 36 has a substantially rectangular geometry, each small side of which carries an internal articulation, respectively. The flange 36 also comprises an orifice in which the head 41 of the actuating member 30 is snapped.

On obtient ainsi un dispositif de déplacement qui est particulièrement fiable et résistant, notamment en ce qu'il prévoit une double élasticité de part et d'autre de la zone d'appui de l'organe d'actionnement 30. En outre, la disposition de l'organe d'actionnement 30 dans le dispositif de déplacement s'en trouve également simplifiée.This gives a displacement device which is particularly reliable and resistant, in particular in that it provides a double elasticity on either side of the bearing zone of the actuating member 30. In addition, the arrangement the actuating member 30 in the displacement device is also simplified.

En outre, dans le mode de réalisation représenté, en position d'éjection (figures 2-4) :

  • l'orifice est surmonté d'une paroi axiale 42 qui vient en appui sur la tige 34 du pointeau 23 ;
  • le manchon 18 comprend une butée arrière 43 pour la paroi 38 ; et
  • la géométrie de l'arrière de la tête d'obturation 35 est agencée pour venir en butée contre une surface complémentaire 44 prévue sur la jupe 19.
In addition, in the embodiment shown, in the ejection position ( Figures 2-4 ):
  • the orifice is surmounted by an axial wall 42 which bears on the rod 34 of the needle 23;
  • the sleeve 18 comprises a rear stop 43 for the wall 38; and
  • the geometry of the rear of the closure head 35 is arranged to abut against a complementary surface 44 provided on the skirt 19.

Ces différents moyens, qui pourraient être prévus de façon indépendante, permettent notamment de maintenir mécaniquement le pointeau 23 lorsqu'il est en position d'éjection, de sorte à le préserver des contraintes induites par le coulissement de l'organe d'actionnement 30 dans le canal de distribution 25.These various means, which could be provided independently, notably make it possible to mechanically maintain the needle 23 when it is in the ejection position, so as to preserve it from the stresses induced by the sliding of the actuating member 30 in the distribution channel 25.

En relation avec les figures, on décrit le fonctionnement de la pompe décrite ci-dessus. En position de repos (figure 1), le clapet 26 est en position d'ouverture et le pointeau 23 en position d'obturation. En outre, la butée 32 prévue dans le canal de distribution 25 est disposée de sorte, sous l'effet du ressort de rappel 14, à contraindre vers le bas l'organe d'actionnement 30 afin, par l'intermédiaire du dispositif de déplacement, de pousser la tête 35 dans l'orifice d'éjection 13. On obtient ainsi une bonne étanchéité au niveau de la fermeture de l'orifice d'éjection 13.In relation to the figures, the operation of the pump described above is described. In the rest position ( figure 1 ), the valve 26 is in the open position and the needle 23 in the closed position. In addition, the stop 32 provided in the distribution channel 25 is arranged so, under the effect of the return spring 14, to constrain the actuating member 30 downwards, via the displacement device pushing the head 35 into the ejection orifice 13. A good seal is thus obtained at the level of the closure of the ejection orifice 13.

Par appui sur le bouton poussoir 12 (figure 2), en début de course de distribution, le pointeau 23 est déplacé en position d'éjection par appui de la collerette 36 qui est mobile sur l'organe d'actionnement 30 qui est fixe. Pour ce faire, la force nécessaire pour déplacer le jonc 31 dans le canal 25 est agencée pour être supérieure à celle nécessaire pour actionner le dispositif de déplacement par l'intermédiaire de la collerette 36. On remarquera que l'ouverture de l'orifice d'éjection 13 a été réalisée sensiblement sans mettre sous pression le liquide, seulement par interaction mécanique entre les pièces de la pompe.By pressing the pushbutton 12 ( figure 2 ), at the start of the dispensing stroke, the needle 23 is moved to the ejection position by pressing the flange 36 which is movable on the actuating member 30 which is fixed. To do this, the force required to move the rod 31 in the channel 25 is arranged to be greater than that required to actuate the displacement device via the flange 36. It will be noted that the opening of the orifice ejection 13 was carried out substantially without pressurizing the liquid, only by mechanical interaction between the parts of the pump.

Sur la suite de la course de distribution (figure 3), le déplacement du bouton poussoir 12 est transmis au piston doseur 24 pour positionner le clapet 26 en position de fermeture. Pour ce faire, la force nécessaire pour déplacer le piston 24 est agencée pour être inférieure à celle nécessaire pour déplacer le jonc 31 dans le canal 25. En variante, on pourrait prévoir une inversion des états montrés sur les figures 2 et 3, c'est-à-dire que le clapet 26 serait d'abord fermé puis l'orifice d'éjection 13 ouvert.On the rest of the race ( figure 3 ), the displacement of the pushbutton 12 is transmitted to the metering piston 24 to position the valve 26 in the closed position. To do this, the force required to move the piston 24 is arranged to be less than that necessary to move the rod 31 in the channel 25. Alternatively, it could be provided an inversion of the states shown on the figures 2 and 3 , that is to say that the valve 26 would first be closed and then the ejection orifice 13 open.

Sur la figure 4, le jonc 31 se déplace dans le canal 25 de sorte à réduire le volume de la chambre de dosage et donc à provoquer la distribution du liquide au travers de l'orifice d'éjection 13. Lors de la distribution du liquide, la mise sous pression du liquide est également très limitée.On the figure 4 , the rod 31 moves in the channel 25 so as to reduce the volume of the metering chamber and thus to cause the distribution of the liquid through the ejection orifice 13. During the distribution of the liquid, the setting liquid pressure is also very limited.

La figure 5 montre le bouton poussoir 12 en fin de course de distribution, jusqu'avant la remontée sous l'effet du ressort 14. Sur cette figure, l'arrêt de l'appui sur le bouton poussoir 12 déplace le pointeau 23 en position d'obturation. Ensuite, le clapet 26 est déplacé en position d'ouverture (figure 6) pour permettre l'aspiration du liquide dans la chambre de dosage lors de la remontée du bouton poussoir 12.The figure 5 shows the push button 12 at the end of the dispensing stroke, until before the ascent under the effect of the spring 14. In this figure, the stop of pressing the push button 12 moves the needle 23 in the closed position . Then, the valve 26 is moved to the open position ( figure 6 ) to allow the aspiration of the liquid into the metering chamber during the raising of the push button 12.
