Description

WO 2004/05841 WO 2004/05841

2 PCT/EP2003/014321 La presente invention a pour objet ('integration d'un clapet anti-retour a bille dans un corps de pompe.
Ce type de clapet comporte .une bille cooperant avec un siege, en' general conique, amenage dans le fiond du corps de pompe. Afin de remplir au mieux sa fonction de clapet anti-retour, la bille doit venir obturer rapiden'ient le siege apres pompage du produit, et par consequent dolt avoir une amplitude de mouvement limitee entre une premiere position, dans laquelle le cfapet est ouvert, et une deuxieme position dans laquelle le clapet est obture.
~ Une solution connue consiste a enfermer la bille dans un espace menage a I'interieur du corps de pompe. Pour empecher la bille de sortir de cet espace, il est frequent de former sur Ve corps de pompe, au-dessus de la bille, des contre-depouilles qui definissent une ouverture sensiblement circulaire de diametre inferieur a celui de la bille. Le mouvement de la bille est alors limite d'un tote par le siege du clapet et de 1'autre par lesdites contre-depouilles.
Plus~les contre-depouilles sont importantes, plus le diametre de I'ouverture qu'elles definissent est faible et meilleure est la retenue de la bille. Or, les procedes de moulage generalement utilises pour realiser le corps de pompe, a 1'exemple du moulage par injection, interdisent la creation directe de contre-depouilles trop importantes duns ledit corps.
Ces dernieres se revelent en efFet considerablement genantes lors de I'etape de demoulage.
Aussi, pour,eviter de creer des contre-depouilles de faible relief qui retiennent mal la bille ou des contre-depouilles trop importantes qui genent le demoulage, il est frequent d'avoir recours a une piece supplemenfaire.
Cette piece disposee au-dessus de la bille remplace les contre depouilles en fermant la cavite dans laquelle la bille est mobile, mais emprisonnee. Cependant, la fabrication dune telle piece represente un tout de production supplementaire et son insertion dans le fond du corps .
de pompe peut s'averer delicate.
La presente iilvention se propose de resoudre les inconvenients des procedes existants et a pour objet ('integration d'un clapet anti-retour a bille dans un corps de pompe, caracterise en ce que CG°i~ ~~ Ctal'~~i?NiATICI~

a) on moule un corps de pompe en menageant sur sa surface interne, au voisinage d'un siege du clapet, des nervures radiates presentant chacune un bord longitudinal et une portion d'extremite detachee de la surface interne, les bords longitudinaux definissant entre eux un espace d'insertion de la bille, au voisinage dudit siege ;
b) on introduit une bille a I'interieur de I'espace menage par lesdites nervures ; et c) on deforme de fa~on plastique les portions d'extremite desdites nervures vers I'interieur d~u corps de pompe, par quoi la bille est emprisonnee a I'interieur dudit espace.
Un tel procede permet de realiser sans difficultes le moulage et le demoulage du corps de pompe. De preference, on moule par injection le corps de pompe. De plus, il n'est plus necessaire d'avoir recours a une piece supplementaire, ce qui facilite le montage du clapet et permet de reduire les Gouts de production.
Avantageusement, les bords longitudinaux desdites nervures radiates s'inscrivent dans une surface cylindrique a base circulaire de diametre inscrit legerement superieur a celui de la bills. L'amplitude du mouvement radial de la bille a I'interieur du cylindre de revolution defini, est ainsi limitee de maniere a fiavoriser le mouvement axial de la bille et par la meme optimiser le fonctionnement du clapet.
Selon un mode, prefere de realisation de ('invention, on utilise, pour I'etape c) du procede un outil introduit axialement a I'interieur du corps de pompe. Cet outil peut presenter un embout plat, cette forme simple permettant de deformer facilement les portions d'extremite des nervures. L'outil utilise peat en outre etre chauffant, la chaleur emise favorisant la deformation desdites portions.
Un deuxieme objet de ('invention est un corps de pompe moule, notamment lors de la mise en oeuvre du procede defini ci-dessus.
lJn tel corps de pompe comprend des nervures radiates sur sa surface interne, reaiisees daps le fond du corps, presentant chacune un bord longitudinal et une portion d'extremite detachee de la surface interne.
De preference, ladite portion d'extremite preserite un bord ~35 superieur qui s'ecarte de ladite surface interne en formant un angle aigu 2 PCT / EP2003 / 014321 The object of the present invention is (the integration of a check valve ball return in a pump body.
This type of valve includes a ball cooperating with a seat, generally conical, feed into the end of the pump body. In order to best fulfill its function of non-return valve, the ball must come close the seat quickly after pumping the product, and therefore must have a limited range of motion between a first position, in which the valve is open, and a second position in which the valve is closed.
~ A known solution is to enclose the ball in a space household inside the pump body. To prevent the ball from coming out of this space, it is common to form on the pump body, above ball, undercuts that define an opening substantially circular in diameter smaller than that of the ball. The movement of the ball is then limited by a tote by the valve seat and on the other by said undercuts.
The larger the undercuts, the greater the diameter of The opening which they define is weak and better is the restraint of the ball. However, the molding processes generally used to carry out the pump body, like injection molding, prohibit the direct creation of too large undercuts in said body.
These latter reveal themselves to be considerably annoying during The demolding step.
Also, to avoid creating undercuts of low relief which hold the ball badly or too large undercuts which cause mold release, it is common to use a part supplemenfaire.
This piece placed above the ball replaces the counter spoils by closing the cavity in which the ball is movable, but imprisoned. However, the manufacture of such a part represents a all of additional production and its insertion into the bottom of the body.
can be tricky.
The present invention proposes to resolve the disadvantages existing processes and has for object ('integration of a non-return valve ball in a pump body, characterized in that CG ° i ~ ~~ Ctal '~~ i? NiATICI ~

a) a pump body is molded while providing on its internal surface, at vicinity of a valve seat, radiate ribs presenting each a longitudinal edge and a portion of end detached from the internal surface, the longitudinal edges defining between them a ball insertion space, in the vicinity of said seat;
b) a ball is introduced inside the household space by said ribs; and c) the end portions of said plastics are deformed in a plastic manner ribs inward of the pump body, whereby the ball is imprisoned inside said space.
Such a method makes it possible to carry out the molding without difficulty and demolding the pump body. Preferably, we mold by injection the pump body. In addition, it is no longer necessary to have recourse to a additional piece, which facilitates the mounting of the valve and allows reduce production tastes.
Advantageously, the longitudinal edges of said ribs radiates are part of a cylindrical surface with a circular base of diameter slightly higher than that of the bills. The amplitude of the radial movement of the ball inside the defined cylinder of revolution, is thus limited so as to favor the axial movement of the ball and by the same optimize the operation of the valve.
According to a preferred embodiment of the invention, we use, for step c) of the process, a tool inserted axially inside the pump body. This tool can have a flat tip, this shape simple to easily deform the end portions of ribs. The tool also uses peat to be heated, the heat emitted promoting the deformation of said portions.
A second object of the invention is a molded pump body, in particular during the implementation of the process defined above.
lJn such a pump body includes radiate ribs on its internal surface, reacted on the bottom of the body, each presenting a longitudinal edge and a portion of the end detached from the surface internal.
Preferably, said end portion preserite an edge ~ 35 upper which deviates from said internal surface by forming an acute angle

3 avec elle. L'angle precite est mesure entre la surface interne du corps de pompe et le plan moyen du bord superieur des portions d'extremite.
Avantageusement, chaque portion d'extremite presente un angle vif entre son bord longitudinal et son bord superieur.
Une telle forme est utilisee lots de I'etape c) de deformation des portions d'extremite du procede decrit precedemment. En effet, en raison de I'inclinaison du bord superieur, lorsqu'un outil introduit axialement dans le corps de pompe vient au contact dudit bord, la pression exercee par I'outil contribue a rabattre lesdites portions d'extremites vets I',interieur du corps de pompe.
Une fois la bille inseree dans Le corps de pompe et une fois .
lesdites portions d'extremite repliees, les rainures definissent une sorte de cage dans laquelle la bille est mobile mais emprisonnee. On obtient alors un ensemble constitue d'un corps de pompe et d'un clapet anti-retour a bille, dans lequel le corps de pompe comprend sur sa surface interne, au voisinage du siege du clapet, des nervures radiates presentant chacune un bord longitudinal et une portion d'extremite detachee de la surface interne deformee plastiquement vets I'interieur du corps de pompe,-lesdits bords longitudinaux definissant entre eux un espace d'insertion de la bille, au voisinage dudit siege de preference, cet espace est sensiblement cylindrique a base circulaire et de diametre inscrit legerement superieur a celui de' la bille.
Un autre objet de ('invention est une pompe comprenant un corps de pompe tel que defini precedemment apres moulage et apres deformation plastique.
L'invention et ses avantages seront mieux compris a la lecture de la description detaillee d'un mode de realisation prefere de ('invention.
La description qui suit se refere aux dessins annexes sur lesquels - la figure 1 est une coupe transversale d'un corps de pompe 30. moule selon ('invention ;
- la figure 2A est une coupe transversale du corps de pompe de , la figure 1 dans lequel est disposee une bille et dans lequel on introduit un outil a embout plat ;
- la figure 2B est une coupe selon le plan A-A de la figure 2a. 3 with her. The above angle is measured between the internal surface of the body of pump and the middle plane of the upper edge of the end portions.
Advantageously, each end portion has a sharp angle between its longitudinal edge and its upper edge.
Such a form is used in batches from step c) of deformation of end portions of the process described above. Indeed, due the inclination of the upper edge, when a tool inserted axially into the pump body comes into contact with said edge, the pressure exerted by The tool contributes to folding down said end portions vets I ', interior of pump body.
Once the ball is inserted into the pump body and once.
said end portions folded back, the grooves define a kind of cage in which the ball is mobile but trapped. We then obtain an assembly consisting of a pump body and a non-return valve a ball, in which the pump body comprises on its internal surface, at in the vicinity of the valve seat, radiate ribs each having a longitudinal edge and an end portion detached from the internal surface plastically deformed inside the pump body, said edges longitudinal defining between them an insertion space for the ball, at preferably in the vicinity of said seat, this space is substantially cylindrical with circular base and diameter slightly greater than that of 'the ball.
Another object of the invention is a pump comprising a pump body as defined above after molding and after plastic deformation.
The invention and its advantages will be better understood on reading of the detailed description of a preferred embodiment of the invention.
The following description refers to the accompanying drawings on which - Figure 1 is a cross section of a pump body 30. mold according to the invention;
- Figure 2A is a cross section of the pump body, Figure 1 in which is arranged a ball and in which we introduce a flat tip tool;
- Figure 2B is a section along the plane AA of Figure 2a.

4 - la figure 3 est une coupe transversals du meme corps de pompe apres ,deformation plastique. des portions d'extrsmite desdites rainures, et ;
- la figure 4 est une coupe transversaie d'un ensemble constitus d'un corps de pompe moule et d'un clapet anti-retour a bills.
Le corps de pompe 1 moule tel que represents sur la figure 1 comprend, sur sa surface interns 3 et au-dessus du siege du clapet 5 destine a etre obture par une bills, des nervures radiates 7.
Ces nervures 7 prssentent chacune un bord longitudinal 9 et une portion d'extrsmits 11 detaches de la surface , interns 3, le bord superieur plan 12, de la portion d'extrsmite 11 s'ecartant de la surface interns 3 en formant un angle a.aigu, avec ells.
De plus, du cots oppose a la surface ~interne 3, ladite portion d'extrsmite 11 presents un angle vif, cet angle est defini par son bord longitudinal 9 et son bord superieur 12. Dans I'exemple represents, Tangle vif precits est complsmentaire de Tangle a.
En reference a la figure.2A, on introduit une bills 13 a I'interieur du corps de pompe 1. Cette bills 13 vient .alors se loger a I'interieur de I'espace d'insertion dsfini par les bords longitudinaux 9 des nervures 11, au voisinage du siege du clapet. Ces bords s'inscrivent de preference dans une surface cylindrique a base circulaire, de diametre inscrit legerement superieur a celui de la bills 1, comme represents sur la figure 2B. Un outii a embout plat l5 est ensuite introduit axialement a I'interieur du corps de pompe 1.
~ En reference a la figure 3, I'embout plat de I'outil 15 vient au contact des portions d'extremits 11 dstachees de la surface interns 3 et exerce sur elles une pression qui les force a se .replier vers I'intsrieur du corps de pompe i. Les portions d'extremite 11 se rabattent de cette maniere en raison de I'inclinaison de leurs bords superieurs 12, sur lesquels la pression de I'outil 15 s'exerce.
Une fois~ deformees plastiquement, les portions d'extrsmite 11 eriferment la bills 13 a I'intsrieur de I'espace dsfini par les bords longitudinaux 9 des nervures 7. La figure 4 reprssente ('ensemble obtenu, constitue au corps de pompe et du clapet anti-retour a bills integre ainsi 35. forms. 4 - Figure 3 is a cross section of the same body of pump afterwards, plastic deformation. end portions of said grooves, and;
- Figure 4 is a cross section of an assembly a mold pump body and a bill check valve.
The pump body 1 mold as shown in Figure 1 includes, on its interns surface 3 and above the valve seat 5 intended to be closed by a bills, radiated ribs 7.
These ribs 7 each have a longitudinal edge 9 and a portion of extremities 11 detached from the surface, interns 3, the edge upper plane 12, of the end portion 11 deviating from the surface interns 3 at an acute angle, with ells.
In addition, costs opposite the internal surface ~ 3, said portion end 11 has a sharp angle, this angle is defined by its edge longitudinal 9 and its upper edge 12. In the example represents, Tangle vif abovementioned is complementary to Tangle a.
With reference to figure 2A, we introduce a bills 13 inside of the pump body 1. This bills 13 is then housed inside of The insertion space defined by the longitudinal edges 9 of the ribs 11, in the vicinity of the valve seat. These edges are preferably part of a cylindrical surface with a circular base, of slightly inscribed diameter higher than that of bills 1, as shown in Figure 2B. A tool with flat tip l5 is then introduced axially inside the body of pump 1.
~ Referring to Figure 3, the flat tip of the tool 15 comes to contact of the end portions 11 detached from the internal surface 3 and exerts a pressure on them which forces them to fold back towards the interior of the pump body i. The end portions 11 fold down from this way due to the inclination of their upper edges 12, on which the pressure of the tool 15 is exerted.
Once plastically deformed, the end portions 11 erectly the bills 13 inside the space defined by the edges longitudinal 9 of the ribs 7. FIG. 4 shows (the assembly obtained, built into the pump body and the integrated non-return bill valve 35. forms.
