DE 2 838 613 divulgue une pompe selon le préambule de la revendication 1. DE 2 838 613 discloses a pump according to the preamble of claim 1.

Avantageusement, lesdits moyens de reprise d'air sont formés par un trou réalisé dans la partie inférieure du corps pompe.Advantageously, said air intake means are formed by a hole made in the lower part of the pump body.

Avantageusement, lesdits moyens d'isolation comportent une enveloppe externe disposée autour dudit corps de pompe.Advantageously, said isolation means comprise an outer envelope disposed around said pump body.

Avantageusement, un passage d'air est défini entre ladite enveloppe et ledit corps de pompe, ledit passage d'air étant relié au trou d'évent de la pompe.Advantageously, an air passage is defined between said envelope and said pump body, said air passage being connected to the vent hole of the pump.

Avantageusement, le trou d'évent comporte un filtre adapté à filtrer l'air entrant.Advantageously, the vent hole comprises a filter adapted to filter the incoming air.

Avantageusement, ladite enveloppe est emmanchée autour du corps de pompe, ledit passage d'air étant défini par au moins une rainure ménagée dans la paroi externe du corps de pompe et/ou dans la paroi interne de l'enveloppe.Advantageously, said envelope is fitted around the pump body, said air passage being defined by at least one groove formed in the outer wall of the pump body and / or in the inner wall of the casing.

Avantageusement, ladite enveloppe comporte une bride radiale formant l'étanchéité avec un réservoir sur lequel la pompe est assemblée.Advantageously, said casing comprises a radial flange forming the seal with a reservoir on which the pump is assembled.

Avantageusement, ladite bride radiale forme un joint de col.Advantageously, said radial flange forms a neck seal.

Avantageusement, ladite enveloppe comporte une chaussette formant l'étanchéité avec la paroi externe du corps de pompe.Advantageously, said envelope comprises a sock forming a seal with the outer wall of the pump body.

Avantageusement, ladite chaussette est élastiquement déformable pour laisser passer de l'air sortant de l'intérieur du corps de pompe à travers lesdits moyens de reprise d'air.Advantageously, said sock is elastically deformable to let air exiting the inside of the pump body through said air intake means.

La présente invention a en outre pour objet un dispositif de distribution de produit fluide comportant une pompe telle que définie ci-dessus, ladite pompe étant montée sur un réservoir au moyen d'une bague ou capsule de fixation.The present invention further relates to a fluid dispenser device comprising a pump as defined above, said pump being mounted on a reservoir by means of a ring or fixing cap.

D'autres caractéristiques et avantages de la présente invention apparaîtront plus clairement au cours de la description détaillée suivante d'un mode de réalisation avantageux de celle-ci, faite en référence au dessin joint, donnés à titre d'exemple non limitatif, et sur lequel la figure unique représente une vue schématique en section transversale d'une pompe de distribution selon un mode de réalisation de la présente invention, en position de repos.Other features and advantages of the present invention will appear more clearly in the course of the following detailed description of an advantageous embodiment thereof, made with reference to the accompanying drawing, given by way of non-limiting example, and on wherein the single figure shows a schematic cross-sectional view of a dispensing pump according to an embodiment of the present invention, in the rest position.

La pompe de la présente invention comporte un corps de pompe 10 qui définit une chambre de dosage 20 entre un piston haut 30 et un piston bas 40. Le piston haut 30 coulisse dans une partie supérieure de corps de pompe 11 et le piston bas 40 coulisse dans une partie inférieure 12 de corps de pompe. De préférence, le piston bas 40 est monté flottant à l'intérieur du corps de pompe et coopère avec un ressort 50 qui est monté sur une paroi de fond du corps de pompe 10 et qui forme le ressort de rappel de la pompe.The pump of the present invention comprises a pump body 10 which defines a metering chamber 20 between a top piston 30 and a bottom piston 40. The top piston 30 slides in an upper part of the pump body 11 and the bottom piston 40 slides. in a lower portion 12 of the pump body. Preferably, the low piston 40 is mounted floating inside the pump body and cooperates with a spring 50 which is mounted on a bottom wall of the pump body 10 and which forms the return spring of the pump.

Selon l'invention, ce ressort 50 est complètement isolé du produit fluide qui est distribué par la pompe. Ceci signifie qu'aucun produit ne pénètre dans la chambre de ressort c'est à dire dans la partie inférieure du corps de pompe dans laquelle se trouve le ressort. Afin d'assurer un fonctionnement sur et fiable de la pompe, la présente invention prévoir de réaliser des moyens de reprise d'air 15 dans la partie inférieure 12 du corps de pompe pour permettre l'entrée et/ou la sortie d'air lors de l'actionnement de la pompe. Ainsi, lorsque le piston bas 40 se déplace à l'intérieur de la partie inférieure du corps de pompe de l'air peut être chassé hors des moyens de reprise d'air 15 alors que lorsque le piston bas remonte, alors de l'air peut être aspiré à travers lesdits moyens de reprise d'air 15. Avantageusement, ces moyens de reprise d'air 15 sont réalisés sous la forme d'un trou réalisé dans la partie inférieure 12 du corps de pompe.According to the invention, this spring 50 is completely isolated from the fluid product which is distributed by the pump. This means that no product enters the spring chamber that is to say in the lower part of the pump body in which the spring is located. In order to ensure an efficient and reliable operation of the pump, the present invention provides for making air intake means 15 in the lower part 12 of the pump body to allow the entry and / or exit of air during actuation of the pump. Thus, when the low piston 40 moves inside the lower part of the pump body, the air can be driven out of the air intake means 15 whereas when the low piston rises, then air can be sucked through said air intake means 15. Advantageously, these air intake means 15 are made in the form of a hole made in the lower part 12 of the pump body.

Selon l'invention, des moyens d'isolation 60 sont prévus pour empêcher la pénétration de produit fluide à l'intérieur de la partie inférieure du corps de pompe, pour garantir que le ressort 50 n'entre pas en contact avec le produit fluide. L'absence totale de contact entre le ressort, généralement métallique et le produit fluide à distribuer est particulièrement important dans le cas de certains produits pharmaceutiques qui risquent d'être altérés par un contact avec ce ressort.According to the invention, isolation means 60 are provided to prevent the penetration of fluid into the lower part of the pump body, to ensure that the spring 50 does not come into contact with the fluid. The total absence of contact between the spring, generally metallic and the fluid to be dispensed is particularly important in the case of certain pharmaceutical products that may be altered by contact with this spring.

Les moyens d'isolation 60 sont avantageusement réalisés sous la forme d'une enveloppe externe qui est emmanchée autour du corps de pompe et qui recouvre le trou 15 pour empêcher le produit fluide de pénétrer dans celui-ci. Avantageusement, l'enveloppe externe a une forme identique à celle du corps de pompe de sorte que l'emmanchement est réalisé avec un contact sur toute la paroi, un passage d'air 61 étant toutefois ménagé entre le corps de pompe 10 et l'enveloppe externe 60, ce passage d'air étant relié au trou d'évent 100 de la pompe. Dans l'exemple représenté sur la figure, le trou d'évent est disposé dans la partie supérieure de la pompe, au niveau du joint de pompe 80 qui forme l'étanchéité entre la pompe et la bague ou capsule de fixation 70, qui est adapté à monter la pompe sur un réservoir (non représenté). Dans l'exemple représenté, le joint 80 est un joint filtrant c'est à dire que l'air qui entre dans la pompe pour remplacer le volume de produit distribué passe à travers ledit filtre 80 qui retire toutes les bactéries et/ou impuretés qui risqueraient d'altérer la qualité du produit.The insulating means 60 are advantageously made in the form of an outer envelope which is fitted around the pump body and which covers the hole 15 to prevent the fluid from entering it. Advantageously, the outer casing has a shape identical to that of the pump body so that the fitting is made with a contact on the entire wall, an air passage 61 being however formed between the pump body 10 and the outer casing 60, this air passage being connected to the vent hole 100 of the pump. In the example shown in the figure, the vent hole is disposed in the upper part of the pump, at the pump seal 80 which forms the seal between the pump and the fixing ring or cap 70, which is adapted to mount the pump on a tank (not shown). In the example shown, the seal 80 is a filter seal, that is to say that the air that enters the pump for replacing the volume of product dispensed passes through said filter 80 which removes all bacteria and / or impurities that could affect the quality of the product.

Avantageusement, l'enveloppe 60 comporte une bride radiale 65 qui est adaptée à former l'étanchéité avec le col du réservoir (non représenté). De préférence, cette bride radiale 65 peut même former le joint de col de la pompe. Dans ce cas, toutefois le trou d'évent 100 est directement relié au passage d'air 61 réalisé entre le corps de pompe et l'enveloppe externe 60, et il faut donc prévoir des moyens de passage d'air, permettant à cet air d'éventation de pénétrer à l'intérieur de la pompe. Ceci est de préférence réalisé au moyen d'une chaussette 62 réalisée de préférence à l'extrémité inférieure de l'enveloppe externe 60, cette chaussette formant d'une part l'étanchéité avec la paroi externe du corps de pompe 10, mais étant élastiquement déformable pour laisser passer l'air d'éventation.Advantageously, the casing 60 comprises a radial flange 65 which is adapted to form the seal with the neck of the reservoir (not shown). Preferably, this radial flange 65 can even form the neck seal of the pump. In this case, however, the vent hole 100 is directly connected to the air passage 61 made between the pump body and the outer casing 60, and it is therefore necessary to provide means for air passage, allowing this air venting to penetrate inside the pump. This is preferably achieved by means of a sock 62 preferably made at the lower end of the outer shell 60, this sock forming on the one hand sealing with the outer wall of the pump body 10, but being elastically deformable to let air vent.

Ainsi, la présente invention permet de garantir une absence totale de contact entre le ressort de rappel de la pompe 50 et le produit fluide, tout en permettant un fonctionnement sur et fiable de la pompe puisque l'air contenu dans la chambre du ressort 50 peut librement circuler en fonction du déplacement du piston bas 40. Parallèlement, les moyens d'isolation, en particulier l'enveloppe externe assure une étanchéité contre l'entrée de produit en contact avec ce ressort, de sorte que les objectifs de la présente invention sont atteints par ce moyen très simple et peu coûteux constitué par l'enveloppe 60. Dans son mode de réalisation représenté sur la figure, dans lequel il forme en outre le joint de col 65 par sa bride radiale supérieure, la présente invention limite en outre le nombre de pièces constitutives pour réaliser l'objectif de l'invention.Thus, the present invention makes it possible to guarantee a total absence of contact between the return spring of the pump 50 and the fluid product, while allowing the pump to operate on and reliably since the air contained in the chamber of the spring 50 can freely move according to the movement of the low piston 40. In parallel, the insulation means, in particular the outer casing provides a seal against the product inlet in contact with this spring, so that the objectives of the present invention are achieved by this very simple and inexpensive means constituted by the casing 60. In its embodiment shown in the figure, in which it further forms the neck seal 65 by its upper radial flange, the present invention further limits the number of component parts to achieve the object of the invention.

Bien que l'invention ait été décrite en référence à un mode de réalisation particulier de celle-ci, la présente invention n'est pas limitée à ce mode de réalisation, mais toutes modifications pourraient y être apportées par un homme du métier sans sortir du cadre de la présente invention tel que défini par les revendications annexées.Although the invention has been described with reference to a particular embodiment thereof, the present invention is not limited to this embodiment, but any modifications could be made by a person skilled in the art without departing from the invention. the scope of the present invention as defined by the appended claims.
