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, ledit liquide pouvant être un parfum, un produit cosmétique ou un produit pharmaceutique.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, said liquid being able to be a perfume, a cosmetic product or a pharmaceutical product.

On connaît de telles pompes comprenant typiquement un gicleur qui est actionné en translation dans un corps par un bouton poussoir sur une course respectivement de distribution et d'aspiration du fluide. En outre, pour permettre la mise en pression du liquide, un piston est monté sur le gicleur de sorte à présenter, en fonction de ladite pression, un état d'obturation et un état d'ouverture d'un chemin de distribution.Such pumps are known, typically comprising a nozzle which is actuated in translation in a body by a push button on a respective distribution and suction stroke of the fluid. In addition, to allow the pressurization of the liquid, a piston is mounted on the nozzle so as to function, according to said pressure, a closed state and an open state of a distribution path.

Pour permettre le passage du piston réversiblement dans ces deux états, deux réalisations sont connues de l'art antérieur :

  • fixer le piston sur le gicleur, le passage d'un état à l'autre se faisant par déformation élastique dudit piston ;
  • monter coulissant le piston sur le gicleur et contraindre élastiquement le déplacement de l'un par rapport à l'autre, le passage d'un état à l'autre étant alors fonction de la résultante des contraintes exercées respectivement par le moyen de contrainte et par la pression sur le liquide.
To allow the passage of the piston reversibly in these two states, two embodiments are known from the prior art:
  • fixing the piston on the nozzle, the passage from one state to another being by elastic deformation of said piston;
  • slidably mounting the piston on the nozzle and elastically constraining the displacement of one relative to the other, the passage from one state to another then being a function of the resultant of the stresses exerted respectively by the stressing means and by the pressure on the liquid.

Dans les réalisations connues, le bouton poussoir est monté directement sur l'extrémité supérieure du gicleur, ce qui nécessite de prévoir un gicleur de diamètre suffisant pour résister aux sollicitations mécaniques induites lors de l'actionnement de la pompe par l'intermédiaire du bouton poussoir.In known embodiments, the push button is mounted directly on the upper end of the nozzle, which requires the provision of a nozzle of sufficient diameter to withstand the mechanical stresses induced during the actuation of the pump via the push button .

On connait également du document FR 2764005 un tube gicleur raccordé d'une part, à une tige creuse axiale et d'autre part, à une tête de pulvérisation.We also know of the document FR 2764005 a nozzle tube connected on the one hand to an axial hollow rod and on the other hand to a spray head.

Toutefois, ces réalisations présentent l'inconvénient de l'encombrement, qui peut s'avérer limitant pour la réalisation de pompes de dimension axiale réduite.However, these embodiments have the disadvantage of the size, which can be limiting for the realization of reduced axial dimension pumps.

En outre, avec des pompes de dimension réduite, il existe un problème de guidage en translation du gicleur, puisque ce guidage est réalisé sur une dimension axiale limitée.In addition, with pumps of reduced size, there is a problem of guiding in translation of the nozzle, since this guidance is performed on a limited axial dimension.

L'invention vise notamment à surmonter les limitations mentionnées ci-dessus, de sorte à permettre la réalisation d'une pompe de dimension axiale réduite.The invention aims in particular to overcome the limitations mentioned above, so as to allow the realization of a pump of reduced axial dimension.

A cet effet, l'invention propose une pompe selon la revendication 1.For this purpose, the invention proposes a pump according to claim 1.

D'autres objets et avantages de l'invention apparaîtront dans la description qui suit, faite en référence aux figures annexées, dans lesquelles :

  • les figures 1a à 1d sont des vues en coupe longitudinale d'une pompe selon un mode de réalisation de l'invention, ladite pompe étant montée sur la bague d'un flacon par l'intermédiaire d'une coupelle, ladite pompe étant représentée respectivement en position de repos (1a), dans sa course de distribution (1b), en fin de course (1c) et dans sa course d'aspiration (1d) ;
  • la figure 2 est une vue analogue à la figure 1d montrant la jupe de la cloche partiellement non coupée.
Other objects and advantages of the invention will appear in the description which follows, made with reference to the appended figures, in which:
  • the Figures 1a to 1d are views in longitudinal section of a pump according to one embodiment of the invention, said pump being mounted on the ring of a bottle by means of a cup, said pump being represented respectively in the rest position ( 1a), in its dispensing stroke (1b), end of stroke (1c) and in its suction stroke (1d);
  • the figure 2 is a view similar to the figure 1d showing the skirt of the bell partially uncut.

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 ci-dessous une pompe destinée à être 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 parfum, un produit cosmétique ou un produit pharmaceutique.In connection with the figures, there is described below a pump to be 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 perfume, a cosmetic product or a pharmaceutical product.

Sur les figures, la pompe est montée sur la bague 1 d'un flacon (non représenté) par l'intermédiaire d'une coupelle 2, notamment en aluminium, qui est déformée pour épouser les formes de la zone d'association afin de bloquer axialement et radialement la pompe relativement au flacon. Dans d'autres modes de réalisation, la coupelle 2 peut comprendre une géométrie et/ou des configurations de moyens d'association sur la bague 1 du flacon qui sont différentes.In the figures, the pump is mounted on the ring 1 of a bottle (not shown) via a cup 2, in particular aluminum, which is deformed to fit the shapes of the association zone in order to block axially and radially the pump relative to the bottle. In other embodiments, the cup 2 may comprise a geometry and / or configurations of association means on the ring 1 of the bottle which are different.

La pompe comprend également un corps 3 de pompe sur lequel est montée la coupelle 2, ledit corps présentant une géométrie cylindro-conique qui est délimitée par une surface intérieure. Plus précisément, le corps 3 comprend une zone supérieure 4 qui est destinée à permettre le montage de la pompe sur le flacon, ladite zone comprenant un bourrelet d'étanchéité supérieur 4a et un bourrelet d'étanchéité latéral 4b. Ainsi, le repliement de la coupelle 2 sur la zone 4 permet de mettre une portée radiale et une portée latérale de la coupelle 2 en appui étanche sur respectivement un bourrelet d'étanchéité 4a, 4b. En variante non représentée, un seul type de bourrelets 4a, 4b peut être prévu pour assurer l'étanchéité entre la coupelle 2 et le corps 3 de pompe.The pump also comprises a pump body 3 on which the cup 2 is mounted, said body having a cylindro-conical geometry which is delimited by an inner surface. More specifically, the body 3 comprises an upper zone 4 which is intended to allow mounting of the pump on the bottle, said zone comprising an upper sealing bead 4a and a lateral sealing bead 4b. Thus, the folding of the cup 2 on the zone 4 makes it possible to put a radial bearing surface and a lateral bearing surface of the cup 2 in sealing engagement on a sealing bead 4a, 4b respectively. As a variant not shown, only one type of beads 4a, 4b may be provided for sealing between the cup 2 and the pump body 3.

En outre, un joint interne 5 est prévu entre le corps 3 et la coupelle 2. Le joint 5 est maintenu en appui sur la surface supérieure de la bague 1 par la coupelle 2 et une rainure d'étanchéité 6 est prévue sur la périphérie du corps 3 pour loger de façon étanche l'extrémité intérieure dudit joint. Dans le mode de réalisation représenté, la périphérie du corps 3 présente également, sous la rainure 6, un bourrelet 7 qui permet d'une part la retenue axiale du joint 5 avant le montage de la pompe sur la bague 1, et d'autre part de former étanchéité entre l'intérieur de la bague 1 et le corps 3. Pour ce faire, le diamètre intérieur du bourrelet 7 est inférieur à celui de l'alésage du joint 5 et de l'ordre du diamètre intérieur de la bague 1.In addition, an inner seal 5 is provided between the body 3 and the cup 2. The seal 5 is held in abutment on the upper surface of the ring 1 by the cup 2 and a sealing groove 6 is provided on the periphery of the body 3 to seal the inner end of said seal. In the embodiment shown, the periphery of the body 3 also has, under the groove 6, a bead 7 which allows on the one hand the axial retention of the gasket 5 before mounting of the pump on the ring 1, and secondly to form a seal between the inside of the ring 1 and the body 3. To do this, the inner diameter of the bead 7 is less than that of the bore of the seal 5 and of the order of the inside diameter of the ring 1.

La pompe comprend un tube plongeur 8 dont la partie supérieure est emmanchée dans une partie inférieure du corps 3 et dont la partie inférieure est immergée dans le liquide contenu dans le flacon.The pump comprises a dip tube 8 whose upper part is fitted in a lower part of the body 3 and whose lower part is immersed in the liquid contained in the bottle.

Par ailleurs, la pompe comprend un gicleur 9 qui est disposé dans le corps 3. Le gicleur 9 est solidaire d'un bouton poussoir 10 qui est actionnable en translation par l'utilisateur de sorte à déplacer ledit gicleur dans ledit corps sur une course respectivement de distribution du liquide (figure 1b) et d'aspiration du liquide (figure 1d). Par ailleurs, un moyen de rappel élastique 11 de la translation du gicleur 9 dans le corps 3 est prévu.Furthermore, the pump comprises a nozzle 9 which is disposed in the body 3. The nozzle 9 is integral with a push button 10 which is actuatable in translation by the user so as to move said nozzle in said body on a stroke respectively of liquid distribution ( figure 1b ) and suction of the liquid ( figure 1d ). Furthermore, an elastic return means 11 of the translation of the nozzle 9 in the body 3 is provided.

Le gicleur 9 comprend un chemin de distribution sensiblement vertical qui est formé de deux orifices amont radiaux 12 et d'un canal 13 en communication avec lesdits orifices. Par ailleurs, l'extrémité aval du canal 13 est insérée dans le bouton poussoir 10 pour être en communication avec une buse de distribution 14 par l'intermédiaire d'un chemin prévu dans ledit bouton, ladite buse étant intégrée dans le bouton poussoir 10 pour pouvoir distribuer le liquide au travers d'un orifice de distribution 15.The nozzle 9 comprises a substantially vertical distribution path which is formed of two radial upstream orifices 12 and a channel 13 in communication with said orifices. Furthermore, the downstream end of the channel 13 is inserted in the push button 10 to be in communication with a dispensing nozzle 14 via a path provided in said button, said nozzle being integrated in the push button 10 to to be able to distribute the liquid through a dispensing orifice 15.

La pompe comprend également un piston 16 qui est monté en contact frottant contre la surface interne du corps 3. Le piston 16 délimite une chambre de dosage 17 qui est en communication avec le tube plongeur 8 par l'intermédiaire d'un clapet formé d'une bille 18 posée sur un siège réalisé dans le fond du corps 3. Le siège est pourvu de pattes 19 de retenue de la bille 18 de sorte à former une cage de rétention de celle-ci au fond de la chambre de dosage 17.The pump also comprises a piston 16 which is mounted in frictional contact against the inner surface of the body 3. The piston 16 defines a metering chamber 17 which is in communication with the dip tube 8 via a valve formed of a ball 18 placed on a seat made in the bottom of the body 3. The seat is provided with tabs 19 for retaining the ball 18 so as to form a retention cage thereof at the bottom of the metering chamber 17.

Le piston 16 est monté coaxialement autour du gicleur 9 sur une zone d'association de sorte à pouvoir présenter un état d'obturation des orifices amont 12 et un état de mise en communication desdits orifices amont avec la chambre de dosage 17.The piston 16 is mounted coaxially around the nozzle 9 on a zone of association so as to be able to present a state of closure of the orifices upstream 12 and a state of communication of said upstream orifices with the metering chamber 17.

Dans le mode de réalisation représenté, la zone d'association est agencée pour permettre un coulissement relatif du piston 16 autour du gicleur 9 entre son état d'obturation et son état de mise en communication. En outre, le coulissement est contraint par un moyen élastique de précontrainte 20 qui est monté en appui entre le piston 16 et le gicleur 9. En variante non représentée, le passage du piston 16 entre ses deux états peut être réalisé par déformation de celui-ci en fonction de la pression appliquée.In the embodiment shown, the association zone is arranged to allow relative sliding of the piston 16 around the nozzle 9 between its closed state and its communication state. In addition, the sliding is constrained by an elastic prestressing means 20 which is mounted in abutment between the piston 16 and the nozzle 9. In a variant not shown, the passage of the piston 16 between its two states can be achieved by deformation of the latter. depending on the applied pressure.

Ainsi, dans son état de repos (figure 1a), le piston 16 est dans son état d'obturation et, un appui sur le bouton poussoir 10, met en pression le liquide contenu dans la chambre de dosage 17 pour, par compensation de l'effort exercé par le moyen de précontrainte 20, faire passer le piston 16 dans son état de distribution (figure 1b) jusqu'en fin de course (figure 1c). Ensuite, par relâchement de l'appui sur le bouton poussoir 10, le moyen de rappel 11 déplace le gicleur 9 sur sa course d'aspiration (figure 1 c) dans laquelle le piston 16 est dans son état d'obturation et la bille 18 est remontée pour permettre l'alimentation de la chambre de dosage 17 en liquide.So, in his state of rest ( figure 1a ), the piston 16 is in its closed state and, pressing on the push button 10, pressurizes the liquid contained in the metering chamber 17, by compensation of the force exerted by the prestressing means 20, to move the piston 16 to its dispensing state ( figure 1b ) until the end of the race ( figure 1c ). Then, by releasing the support on the push button 10, the return means 11 moves the nozzle 9 on its suction stroke ( Figure 1 (c) in which the piston 16 is in its closed state and the ball 18 is raised to allow the supply of the metering chamber 17 in liquid.

Pour assurer l'étanchéité de la chambre de dosage 17, le piston 16 comprend une lèvre d'étanchéité inférieure 16a qui est en contact frottant sur la surface interne du corps 3. La lèvre 16a est annulaire et s'étend en direction de la chambre de dosage 17 en s'écartant de l'axe du piston 16. Le piston 16 comprend en outre une lèvre d'étanchéité supérieure 16b qui est en contact frottant sur la surface interne du corps 3, ladite lèvre supérieure s'étendant à l'opposé de la lèvre inférieure 16a par rapport à la direction de translation du piston 16.To ensure the sealing of the metering chamber 17, the piston 16 comprises a lower sealing lip 16a which is in rubbing contact on the inner surface of the body 3. The lip 16a is annular and extends towards the chamber the piston 16 further comprises an upper sealing lip 16b which is in rubbing contact on the inner surface of the body 3, said upper lip extending to the opposite of the lower lip 16a with respect to the direction of translation of the piston 16.

Pour compenser les éventuels défauts d'alignement entre l'axe de la poussée exercée sur le bouton poussoir 10 et l'axe du corps 3, la zone d'association de la pompe selon le mode de réalisation représenté est agencée pour permettre un rotulage étanche entre le piston 10 et le gicleur 9. Ainsi, en cas d'appui désaxé sur le bouton poussoir 10, le désalignement du gicleur 9 par rapport au corps 3 est compensé par le rotulage afin de maintenir le piston 16 dans l'axe, de sorte notamment à maintenir l'étanchéité de la chambre de dosage 17. En particulier, le rotulage permet de maintenir les lèvres d'étanchéité 16a, 16b en contact sur la surface interne du corps 3.To compensate for any misalignment between the axis of the thrust exerted on the push button 10 and the axis of the body 3, the association zone of the pump according to the embodiment shown is arranged to allow a sealed swivel between the piston 10 and the nozzle 9. Thus, in case of support off the push button 10, the misalignment of the nozzle 9 relative to the body 3 is compensated by the swiveling to maintain the piston 16 in the axis, so in particular to maintain the sealing of the metering chamber 17. In particular, the swiveling maintains the sealing lips 16a, 16b in contact with the inner surface of the body 3.

Dans le mode de réalisation représenté, le rotulage est obtenu en prévoyant une zone d'association comprenant une saillie 21 de centrage et d'étanchéité du piston 16 autour du gicleur 9 et un espace annulaire 22 permettant un débattement angulaire du gicleur 9 relativement au piston 16. Plus précisément, sur les figures, le piston 16 comprend un alésage qui présente un diamètre supérieur délimitant l'espace annulaire 22 autour de la périphérie du gicleur 9, et un diamètre inférieur formant saillie radiale 21 de centrage qui est en contact étanche autour de la périphérie du gicleur 9. Dans cette réalisation, le piston 16 comprend une cheminée 23 autour du diamètre supérieur, le ressort de précontrainte 20 étant en appui sur la surface supérieure de ladite cheminée. En variante non représentée, la géométrie de la périphérie du gicleur 9 pourrait être adaptée pour former la zone d'association permettant le rotulage.In the embodiment shown, the swiveling is obtained by providing a zone of association comprising a projection 21 for centering and sealing the piston 16 around the nozzle 9 and an annular space 22 allowing an angular displacement of the nozzle 9 relative to the piston 16. More specifically, in the figures, the piston 16 comprises a bore which has a larger diameter defining the annular space 22 around the periphery of the nozzle 9, and a lower diameter 21 radial centering projection which is in sealing contact around the periphery of the nozzle 9. In this embodiment, the piston 16 comprises a chimney 23 around the upper diameter, the prestressing spring 20 being in abutment on the upper surface of said chimney. As a variant not shown, the geometry of the periphery of the nozzle 9 could be adapted to form the association zone for swiveling.

Pour permettre le rotulage dans une plage angulaire adaptée, le rapport entre les dimensions axiales des diamètres supérieur et inférieur peut être compris entre 8 et 4.To allow swiveling in a suitable angular range, the ratio between the axial dimensions of the upper and lower diameters may be between 8 and 4.

La pompe comprend en outre une cloche supérieure 24 qui est interposée entre le gicleur 9 et le bouton poussoir 10, ladite cloche permettant de renforcer localement le gicleur 9, de sorte à pouvoir réaliser un gicleur 9 de diamètre réduit dans les zones moins sollicitées mécaniquement. En outre, la périphérie de la cloche 24 comprend une surface d'emmanchement 25 d'un alésage du bouton poussoir 10, ladite surface étant pourvue d'une gorge annulaire 26 dans laquelle une saillie formée dans l'alésage du bouton poussoir est introduite pour fiabiliser ledit emmanchement.The pump further comprises an upper bell 24 which is interposed between the nozzle 9 and the push button 10, said bell for locally reinforcing the nozzle 9, so as to make a nozzle 9 of reduced diameter in areas less mechanically stressed. In addition, the periphery of the bell 24 comprises a fitting surface 25 of a bore of the push button 10, said surface being provided with an annular groove 26 in which a projection formed in the bore of the push button is introduced to to make said fitting more reliable.

La cloche 24 est emmanchée autour de la partie supérieure du gicleur 9 en laissant une surface supérieure 27 dudit gicleur libre afin que le bouton poussoir 10 vienne en appui axial sur ladite surface formant ainsi butée.The bell 24 is fitted around the upper part of the nozzle 9 leaving an upper surface 27 of said free nozzle so that the push button 10 bears axially on said surface thus forming a stop.

La pompe représentée comprend également un extenseur 28 solidarisé au corps 3 par emmanchement étanche à l'intérieur dudit corps, le piston 16 étant monté coulissant dans l'extenseur 28. L'extenseur 28 présente une géométrie cylindro-conique comprenant une portée inférieure 29 en contact avec la périphérie du piston 16, et notamment en contact étanche avec la périphérie de la cheminée 23, de sorte à assurer le guidage dudit piston en limitant son rotulage par rapport audit corps.The pump shown also comprises a stent 28 secured to the body 3 by sealing inside said body, the piston 16 being slidably mounted in the stent 28. The stent 28 has a cylindro-conical geometry comprising a lower bearing surface 29. contact with the periphery of the piston 16, and in particular in sealing contact with the periphery of the chimney 23, so as to ensure the guidance of said piston by limiting its swiveling relative to said body.

Le ressort de rappel 11 est en appui sur l'extérieur de la portée inférieur 29. En outre, la périphérie de l'extenseur 28 comprend une saillie radiale 30 qui forme butée axiale de l'extenseur 28 sur une marche formée dans le corps 3. Par ailleurs, un trou d'évent 31 est formé dans le corps 3 en dessous de la zone d'emmanchement de l'extenseur 28.The return spring 11 is resting on the outside of the lower bearing surface 29. In addition, the periphery of the expander 28 comprises a radial projection 30 which forms an axial stop of the expander 28 on a step formed in the body 3 In addition, a vent hole 31 is formed in the body 3 below the fitting zone of the stent 28.

Pour améliorer le guidage en translation du gicleur 9, la cloche 24 comprend une jupe inférieure 32 qui s'étend sous la surface d'emmanchement 25 du bouton poussoir 10, ladite jupe présentant un diamètre extérieur permettant un glissement sans jeu de ladite jupe dans l'extenseur 28 lors du déplacement en translation du gicleur 9. En outre, cette réalisation permet de limiter l'angle de rotulation du gicleur 9. Par ailleurs, la présence de la jupe 32 masque latéralement les ressorts 11, 20 lorsque la pompe est en position de repos.To improve the translational guidance of the nozzle 9, the bell 24 comprises a lower skirt 32 that extends under the fitting surface 25 of the push button 10, said skirt having an outer diameter allowing a play free sliding of said skirt in the liner. expander 28 during displacement in translation of the nozzle 9. In addition, this embodiment makes it possible to limit the angle of rotation of the nozzle 9. Moreover, the presence of the skirt 32 laterally masks the springs 11, 20 when the pump is in rest position.

Comme représenté sur la figure 2, la jupe 32 présente au moins une zone en creux 40 débouchant axialement de sorte à permettre le passage d'air entre ladite jupe et l'extenseur 28. Ainsi, la différence de pression entre l'intérieur et l'extérieur de l'extenseur 28 est limitée de sorte à ne pas interférer sur la course d'aspiration du gicleur 9.As shown on the figure 2 , the skirt 32 has at least one hollow zone 40 opening axially so as to allow the passage of air between said skirt and the expander 28. Thus, the pressure difference between the inside and the outside of the expander 28 is limited so as not to interfere with the suction stroke of the nozzle 9.

Le ressort de rappel 11 et le ressort de précontrainte 20 sont disposés de façon concentrique, ledit ressort de rappel présentant le plus grand diamètre. Les ressorts 11, 20 sont d'une part en appui sur la cloche 24 et d'autre part en appui respectivement sur l'extenseur 28 et le piston 16. Cette réalisation permet d'éviter la mise en contact des ressorts 11, 20 avec le fluide, et de contribuer à la compacité axiale de la pompe. Par ailleurs, les ressorts 11, 20 n'étant pas visibles dans la pompe, on peut prévoir que le corps 3, la bille 18 et/ou le tube plongeur 8 soit réalisé dans un matériau transparent ou au moins translucide de sorte à fournir une pompe particulièrement discrète et esthétique. En outre, la compacité de la pompe permet son logement dans la bague 1, seul le tube plongeur 8 dépassant à l'intérieur du flacon.The return spring 11 and the preload spring 20 are concentrically arranged, said return spring having the largest diameter. The springs 11, 20 are on the one hand resting on the bell 24 and on the other hand bearing respectively on the expander 28 and the piston 16. This embodiment makes it possible to prevent the springs 11, 20 from coming into contact with each other. fluid, and contribute to the axial compactness of the pump. Moreover, the springs 11, 20 not being visible in the pump, it is possible for the body 3, the ball 18 and / or the dip tube 8 to be made of a transparent material or at least a translucent material so as to provide a particularly discreet and aesthetic pump. In addition, the compactness of the pump allows its housing in the ring 1, only the dip tube 8 protruding inside the bottle.

Le ressort 11 est en appui sous la jupe 32, ce qui permet d'utiliser un ressort de diamètre important afin que les efforts exercés par ledit ressort puissent contribuer à la stabilité angulaire du gicleur 9 relativement au corps 3. Par ailleurs, les ressorts 11, 20 sont à spires inversées pour faciliter la rotation dans les deux sens du bouton poussoir 10 autour de son axe.The spring 11 is supported under the skirt 32, which allows the use of a large diameter spring so that the forces exerted by said spring can contribute to the angular stability of the nozzle 9 relative to the body 3. In addition, the springs 11 20 are inverted turns to facilitate rotation in both directions of the push button 10 about its axis.

La partie inférieure du gicleur 9 qui est disposée dans la chambre de dosage 17 est agencée pour former un volume mort 33 afin de limiter la vitesse d'amorçage de la pompe. Toutefois, pour conserver une dose constante, le volume mort 33 est en communication avec la chambre de dosage par l'intermédiaire de passages radiaux 34.The lower portion of the nozzle 9 which is disposed in the metering chamber 17 is arranged to form a dead volume 33 to limit the priming speed of the pump. However, to maintain a constant dose, the dead volume 33 is in communication with the metering chamber via radial passages 34.

Selon la réalisation représentée, la partie inférieure comprend une couronne 35 présentant des créneaux 36, lesdits créneaux étant agencés pour définir la fin de course du gicleur 9 en venant en appui sur la paroi inférieure de la chambre de dosage 17 (figure 1c). Ainsi, le volume mort 33 est défini sous la couronne 35 et les passages radiaux 34 sont formés entre les créneaux 36 adjacents. En outre, la présence des créneaux 36 permet, en fin de course, d'éviter un effet ventouse de la couronne 35 sur la paroi inférieure de la chambre de dosage 17.According to the embodiment shown, the lower part comprises a ring 35 having slots 36, said slots being arranged to define the end of stroke of the nozzle 9 while bearing on the bottom wall of the metering chamber 17 ( figure 1c ). Thus, the dead volume 33 is defined under the ring 35 and the radial passages 34 are formed between the adjacent slots 36. In addition, the presence of the slots 36 allows, at the end of the race, to avoid a suction effect of the ring 35 on the bottom wall of the metering chamber 17.

Par ailleurs, la couronne 35 présente une génératrice inclinée extérieurement par rapport à l'axe du gicleur 9 et le piston 16 comprend une zone d'étanchéité 37 qui, dans l'état d'obturation, est en contact sur la surface extérieure de la couronne 35. En outre, la portée inférieure 29 est agencée pour coopérer avec une portée complémentaire du piston 16 de sorte, dans l'état d'obturation, que l'effort exercé par le moyen de rappel 11 améliore l'étanchéité de la chambre de dosage 17 au niveau de ladite zone d'étanchéité en contact avec la couronne 35.Furthermore, the ring 35 has a generatrix inclined externally relative to the axis of the nozzle 9 and the piston 16 comprises a sealing zone 37 which, in the closed state, is in contact on the outer surface of the In addition, the lower bearing surface 29 is arranged to cooperate with a complementary bearing surface of the piston 16 so that, in the closed state, the force exerted by the return means 11 improves the sealing of the chamber. metering device 17 at said sealing zone in contact with the ring gear 35.

Plus précisément, la surface extérieure de la portée complémentaire présente une surface annulaire qui est inclinée extérieurement, et une surface annulaire radiale. Ainsi, par appui sur cette surface, la zone d'étanchéité 37 qui est prévue à l'opposé, est plaquée sur la surface extérieure de la couronne 35. Cette réalisation permet d'assurer l'étanchéité entre l'extenseur 28 et le piston 16 et également d'améliorer la puissance d'aspiration de la pompe.More specifically, the outer surface of the complementary surface has an annular surface which is inclined externally, and a radial annular surface. Thus, by pressing on this surface, the sealing zone 37 which is provided opposite, is pressed against the outer surface of the ring 35. This embodiment makes it possible to seal between the expander 28 and the piston 16 and also improve the suction power of the pump.
