This is therefore neither deformed or damaged when the piston reaches this position of 50. This is the case both at the time of assembly, and at each actuation of the pump.
- the lower edge 54 of the lower lip 51 of the piston 50 can be oblique so that the non-active part the lower edge 54 is in abutting contact with said radial shoulder 11 in said dispensing position, while the active sealing portion 53 is not in contact with said radial shoulder and extends inside said axial clearance 15.

- the present invention thus makes it possible to avoid a degradation of performance of the pump, and therefore to extend the service life of the pump, eliminating any risk of damage or deformation of the lip lower 51 of the piston 50, in particular at its active sealing portion 53.

Abstract
Description
La présente invention concerne une pompe de distribution de produit fluide à actionnement manuel, ainsi qu'un dispositif de distribution de produit fluide comportant une telle pompe.The present invention relates to a product dispensing pump manually operated fluid, as well as a product dispensing device fluid comprising such a pump.
De manière connue, les pompes comportent généralement un corps de pompe dans lequel coulisse un piston entre une position de repos et une position de distribution, ledit piston étant déplacé par l'utilisateur vers sa position de distribution pour distribuer du produit contenu dans ladite pompe, par exemple dans une chambre de pompe. De manière classique, la pompe comporte des moyens pour définir la position de repos et des moyens pour définir la position de distribution du piston. Ces moyens sont généralement réalisés sous la forme de butées qui définissent les positions d'extrémités du piston. Il est connu de réaliser la butée définissant la position de distribution au moyen d'un épaulement dans le corps de pompe, de sorte que lorsque le piston vient buter contre ledit épaulement, il n'est plus possible de déplacer davantage le piston par rapport au corps de pompe, ce qui définit la position d'extrémité d'actionnement ou position de distribution du piston.In known manner, the pumps generally comprise a body of pump in which slides a piston between a rest position and a position of distribution, said piston being moved by the user towards his position of distribution for dispensing product contained in said pump, for example in a pump chamber. In a conventional manner, the pump comprises means for defining the rest position and means for defining the position piston distribution. These means are usually realized in the form stoppers which define the end positions of the piston. It is known to realize the stop defining the distribution position by means of a shoulder in the pump body, so that when the piston abuts against said shoulder, it is no longer possible to further move the piston by relative to the pump body, which defines the actuating end position or dispensing position of the piston.
Cette mise en oeuvre présente toutefois un inconvénient. Ainsi, à chaque actionnement de la pompe, la lèvre d'étanchéité du piston, et notamment la partie active de cette lèvre d'étanchéité, c'est à dire la partie qui forme le contact étanche entre la lèvre et le corps de pompe, vient buter contre l'épaulement radial, de sorte que cette partie active est soumise à des contraintes ou forces axiales. Après plusieurs actionnements de la pompe, ceci peut entraíner une déformation ou un endommagement de la lèvre d'étanchéité du piston, et notamment de sa partie active d'étanchéité, ce qui peut avoir pour conséquence une dégradation des performances de la pompe. De manière similaire, il est fréquent que lors de l'assemblage de la pompe, le piston est déplacé vers sa position de distribution par la machine d'assemblage. Ce déplacement peut être réalisé de manière relativement violente, et en tout cas beaucoup plus fortement que lorsque la pompe est utilisée par un utilisateur. Dans ce cas, la lèvre d'étanchéité inférieure vient buter assez violemment contre l'épaulement radial du corps de pompe lors de l'assemblage de la pompe. Ceci peut avoir comme conséquence une dégradation ou un endommagement de la lèvre d'étanchéité du piston dès l'assemblage de la pompe.This implementation however has a disadvantage. So at each actuation of the pump, the sealing lip of the piston, and in particular the active part of this sealing lip, ie the part that forms the contact sealed between the lip and the pump body, abuts against the shoulder radial, so that this active part is subjected to stresses or forces Axial. After several actuations of the pump, this can lead to deformation or damage to the sealing lip of the piston, and of its active sealing part, which may have the consequence a degradation of the performance of the pump. Similarly, it is often that when assembling the pump, the piston is moved to its dispensing position by the assembly machine. This displacement can be achieved in a relatively violent way, and in any case much more strongly only when the pump is used by a user. In this case, the lip lower seal abuts violently against the radial shoulder pump body when assembling the pump. This can have as consequence degradation or damage to the sealing lip of the piston as soon as the pump is assembled.

La présente invention a pour but de fournir une pompe de distribution de produit fluide qui ne reproduit pas les inconvénients susmentionnés.The present invention aims to provide a dispensing pump of fluid product that does not reproduce the aforementioned disadvantages.
La présente invention a ainsi pour but de fournir une pompe de distribution de produit fluide qui protège le piston et évite toute dégradation des performances de la pompe, améliorant ainsi la durée de vie de celle-ci.The present invention thus aims to provide a pump of fluid distribution which protects the piston and avoids any degradation of performance of the pump, thus improving the service life of the pump.
La présente invention a également pour but de fournir une telle pompe de distribution de produit fluide qui soit simple et peu coûteuse à fabriquer et à assembler.The present invention also aims to provide such a pump of fluid dispensing that is simple and inexpensive to manufacture and to assemble.
La présente invention a donc pour objet une pompe de distribution de produit fluide à actionnement manuel, comportant un corps de pompe et un piston coulissant de manière étanche dans ledit corps de pompe entre une position de repos et une position de distribution, ledit piston comportant au moins une lèvre d'étanchéité inférieure en contact étanche avec ledit corps de pompe, ledit corps de pompe comportant un épaulement radial vers l'intérieur, ledit corps de pompe comporte un dégagement annulaire axial au niveau dudit épaulement radial de sorte que la partie active d'étanchéité de la lèvre inférieure est hors de tout contact avec ledit épaulement radial en position de distribution du piston, de sorte qu'aucune force axiale ne s'exerce sur ladite partie active, ledit épaulement radial coopérant avec ladite lèvre inférieure du piston pour former une butée pour ledit piston et définir sa position de distribution.The subject of the present invention is therefore a pump for dispensing fluid product with manual actuation, comprising a pump body and a piston sliding in a sealed manner in said pump body between a rest position and a dispensing position, said piston having less a lower sealing lip in sealing contact with said body of pump, said pump body having a radially inward shoulder, said pump body comprises an axial annular clearance at the level of said radial shoulder so that the active sealing part of the lower lip is out of contact with said radial shoulder in dispensing position of the piston, so that no axial force is exerted on said active part, said radial shoulder cooperating with said lower lip of the piston for forming an abutment for said piston and defining its dispensing position.
Avantageusement, le bord axial inférieur de la lèvre inférieure du piston est oblique, de sorte qu'en position de distribution du piston, la partie non-active du bord inférieur est en contact de butée avec ledit épaulement radial du corps de pompe, alors que la partie active d'étanchéité s'étend dans ledit dégagement annulaire.Advantageously, the lower axial edge of the lower lip of the piston is oblique, so that in the piston distribution position, the non-active part of the lower edge is in abutting contact with said radial shoulder of the body of pump, while the active sealing portion extends into said clearance annular.
La présente invention a également pour objet un dispositif de distribution de produit fluide comportant une pompe telle que définie ci-dessus. The present invention also relates to a dispensing device fluid product comprising a pump as defined above.
D'autres caractéristiques et avantages de la présente invention apparaítront plus clairement au cours de la description détaillée suivante d'un mode de réalisation de celle-ci, faite en référence aux dessins joints, donnés à titres d'exemples non limitatifs, et sur lesquels :
- la figure 1 est une vue schématique en section transversale d'une pompe de distribution de produit fluide à laquelle s'adapte la présente invention ; et
- la figure 2 est une vue schématique agrandie d'une partie de la figure 1, montrant un mode de réalisation avantageux de la présente invention.
- Figure 1 is a schematic cross-sectional view of a fluid dispenser pump to which the present invention fits; and
- Fig. 2 is an enlarged schematic view of a portion of Fig. 1, showing an advantageous embodiment of the present invention.
La figure 1 montre schématiquement une pompe de distribution de produit fluide à laquelle peut s'appliquer la présente invention. Il est toutefois entendu que la présente invention ne se limite pas à la pompe représentée sur la figure 1, mais peut être appliquée à toutes les pompes dans lesquelles un piston coulisse dans un corps de pompe, la position d'extrémité d'actionnement, ou position de distribution, du piston étant définie par une butée coopérant avec la lèvre d'étanchéité du piston.Figure 1 schematically shows a distribution pump of fluid product to which the present invention can be applied. It is however understood that the present invention is not limited to the pump shown on the Figure 1, but can be applied to all pumps in which a piston slides in a pump body, the actuating end position, or distribution position, the piston being defined by a stop cooperating with the sealing lip of the piston.
La pompe de la figure 1 comporte un corps de pompe 10 dans lequel
coulisse un premier piston 50 relié, de préférence de manière monobloc, à une
tige d'actionnement 60, avantageusement creuse et incorporant un canal
d'expulsion 61. La pompe de l'exemple de la figure 1 comporte en outre un
second piston 55 qui coulisse dans une partie de diamètre réduit du corps de
pompe. Une chambre de pompe 20 est définie entre ces deux pistons 50 et 55,
ainsi qu'entre un clapet d'entrée 30 et un clapet de sortie 40. Lors de
l'actionnement de la pompe, le second piston 55 se déplace plus rapidement que
le premier piston 50, en raison des différences de diamètre, et le second piston 55
est adapté à ouvrir mécaniquement le clapet de sortie 40 en fin de course
d'actionnement du piston 50. Un virole 80 est en outre emmanchée dans le bord
supérieur du corps de pompe 10 pour définir la position de repos du piston 50, et
la pompe représentée peut être assemblée sur un réservoir (non représenté) au
moyen d'une bague de fixation 1 qui peut être quelconque, et notamment
vissable, sertissable ou encliquetable. De manière connue, un joint de col 5 est
généralement interposé entre la bague de fixation 1 et le bord supérieur du
réservoir (non représenté). Un ressort 70 est adapté à ramener automatiquement
la pompe vers sa position de repos après chaque actionnement.The pump of FIG. 1 comprises a
La figure 2 montre l'objet de la présente invention. Il est à noter que la figure 2 est une représentation très schématique, dans laquelle certaines formes ou déformations ont été exagérées pour simplifier la représentation.Figure 2 shows the object of the present invention. It should be noted that Figure 2 is a very schematic representation, in which certain forms or distortions have been exaggerated to simplify the representation.
Selon l'invention, le corps de pompe 10 comporte un épaulement radial
vers l'intérieur 11 qui définit la position de distribution du piston 50. Pour éviter
un endommagement de la lèvre d'étanchéité 51 du piston 50, et plus
particulièrement de la partie active d'étanchéité 53 de cette lèvre inférieure 51, le
corps de pompe comporte au niveau dudit épaulement radial 11 un dégagement
annulaire axial 15. Ainsi, lorsque le piston 50 est en position de distribution, qui
est celle représentée sur la figure 2, la partie active d'étanchéité 53 de la lèvre
inférieure 51 n'est pas en contact avec l'épaulement radial 11 mais s'étend à
l'intérieur dudit dégagement annulaire axial 15, de sorte qu'aucune force ou
contrainte axiale ne s'exerce sur ladite partie active 53. Celle-ci n'est donc ni
déformée ni endommagée lorsque le piston arrive dans cette position de
distribution 50. Ceci est le cas à la fois lors de l'assemblage, et à chaque
actionnement de la pompe.According to the invention, the
Comme représenté schématiquement sur la figure 2, le bord inférieur 54
de la lèvre inférieure 51 du piston 50 peut être oblique de sorte que la partie non-active
du bord inférieur 54 est en contact de butée avec ledit épaulement radial
11 dans ladite position de distribution, alors que la partie active d'étanchéité 53
n'est pas en contact avec ledit épaulement radial et s'étend à l'intérieur dudit
dégagement axial 15. La dimension radiale et/ou la profondeur dudit
dégagement annulaire 15 peut être adaptée à la forme particulière du bord
inférieur 54 de la lèvre inférieure 51 du piston 50, du moment qu'en position de
butée, la partie active 53, c'est à dire celle formant l'étanchéité n'entre pas en
contact avec le fond dudit dégagement axial 15. As shown schematically in FIG. 2, the
La présente invention permet donc d'éviter une dégradation des
performances de la pompe, et donc d'allonger la durée de vie de celle-ci, en
éliminant tous risques d'endommagement ou de déformation de la lèvre
inférieure 51 du piston 50, notamment au niveau de sa partie active d'étanchéité
53.The present invention thus makes it possible to avoid a degradation of
performance of the pump, and therefore to extend the service life of the pump,
eliminating any risk of damage or deformation of the lip
lower 51 of the
Bien que la présente invention ait été décrite en référence à un mode de réalisation particulier de celle-ci, il est entendu qu'un homme du métier peut y apporter toutes modifications sans sortir du cadre de la présente invention tel que défini par les revendications annexées.Although the present invention has been described with reference to a particular embodiment of it, it is understood that a person skilled in the art may make any modifications without departing from the scope of the present invention as defined by the appended claims.
