Description

La présente invention concerne le domaine des pompes hydrauliques pour piscines.The present invention relates to the field of hydraulic pumps for swimming pools.

Plus particulièrement, la présente invention concerne un corps de partie hydraulique d'un dispositif de pompage et pré filtration ou pompe, ledit corps de partie hydraulique étant apte à coopérer avec un corps de moteur électrique de pompe, ledit corps de partie hydraulique incluant un corps de pré filtre comprenant un orifice d'aspiration apte à coopérer avec un tuyau rigide d'arrivée d'eau provenant d'une piscine, ledit corps de pré filtre comprenant un orifice latéral communiquant ou étant apte à communiquer latéralement avec un corps d'enveloppe de turbine comprenant un orifice de refoulement apte à refouler l'eau en direction de la piscine, de préférence via un filtre à sable ou autre accessoire de traitement de l'eau, de type NCC par exemple, lorsque ladite turbine est entraînée en rotation par un moteur électrique coopérant avec le dit corps d'enveloppe.More particularly, the present invention relates to a body of hydraulic part of a pumping device and pre-filtration or pump, said body of hydraulic part being adapted to cooperate with an electric pump motor body, said body of hydraulic part including a body pre-filter comprising a suction port adapted to cooperate with a rigid water inlet pipe from a pool, said pre-filter body comprising a lateral orifice communicating or being able to communicate laterally with an envelope body turbine comprising a discharge orifice capable of discharging water towards the pool, preferably via a sand filter or other water treatment accessory, NCC for example, when said turbine is rotated by an electric motor cooperating with said envelope body.

On comprend que le corps d'enveloppe de turbine renferme la turbine sous forme d'ailette ou aube, montée en rotation axiale dans le corps d'enveloppe de turbine. Lorsque le corps d'enveloppe de turbine est monté en fixation avec le moteur électrique, la turbine est enveloppée dans un corps qui comprend de l'eau en pression lorsque le moteur électrique est activé, tandis que le corps de pré filtre, lui, est en dépression relative. Donc l'eau arrive dans le corps de pré filtre par ledit orifice d'aspiration, passe à travers un système de filtration à l'intérieur du corps de pré filtre, notamment du type panier, avant d'arriver dans le corps d'enveloppe de la turbine pour être refoulée par ledit orifice de refoulement en direction du filtre à sable ou autre accessoire-de traitement de l'eau.It is understood that the turbine casing body encloses the impeller in the form of blades or vanes, mounted in axial rotation in the turbine casing body. When the turbine casing body is mounted in attachment with the electric motor, the turbine is wrapped in a body which comprises pressurized water when the electric motor is activated, while the pre-filter body, it is in relative depression. Thus the water arrives in the pre-filter body via said suction orifice, passes through a filtration system inside the pre-filter body, in particular of the basket type, before reaching the envelope body. the turbine to be discharged by said discharge port towards the sand filter or other accessory-water treatment.

Une pompe hydraulique de ce type est décrite dans DE 20107470 considéré comme le document décrivant l'état de la technique le plus proche.A hydraulic pump of this type is described in DE 20107470 regarded as the document describing the closest state of the art.

La pose de la pompe et son raccordement au circuit d'arrivée d'eau de la piscine, d'une part, et, d'autre part, à un tuyau d'alimentation du filtre à sable, constituent une des phases quelquefois longues et délicates. Il est, notamment, quelquefois nécessaire de prévoir de nombreux coudes pour faire coïncider le tuyau d'arrivée d'eau provenant de la piscine à partir du skimmer d'aspiration de surface ou de la bonde de fond ou autres aspiration d'eau de la piscine et l'orifice d'aspiration, ce qui, non seulement, pose quelquefois des difficultés d'encombrement mais, en outre, affecte le rendement de la pompe. En effet, la multiplicité des coudes induit inévitablement des pertes de charge.The installation of the pump and its connection to the water inlet circuit of the pool, on the one hand, and, on the other hand, to a sand filter supply pipe, constitute one of the sometimes long phases and delicate. It is, in particular, it is sometimes necessary to provide many elbows to match the water inlet pipe coming from the pool from the surface suction skimmer or the drain or other water suction of the pool and the suction port, which not only sometimes poses difficulties of size but, in addition, affects the efficiency of the pump. Indeed, the multiplicity of elbows inevitably induces loss of load.

Pour résoudre ce problème, la présente invention fournit un corps de partie hydraulique de pompe comprenant un corps de pré filtre caractérisé en ce que ledit corps de pré filtre comprend :

  • une partie supérieure comprenant une paroi comprenant ledit orifice d'aspiration, et un deuxième grand orifice inférieur, et
  • une partie inférieure comprenant une paroi périphérique comprenant un troisième grand orifice supérieur communiquant avec ledit deuxième grand orifice inférieur, de préférence de même dimension circulaire que celui-ci, et un orifice latéral communiquant ou étant apte à communiquer latéralement avec ledit corps d'enveloppe de turbine, et
  • lesdites partie supérieure et partie inférieure dudit corps de pré filtre sont indépendantes l'une de l'autre et montées en fixation amovible étanche au niveau des rebords périphériques desdits deuxième et troisième grands orifices, de préférence de mêmes sections circulaires, de manière à ce qu'ils coïncident l'un contre l'autre par fixation, l'orientation des deux dites parties supérieure et partie inférieure du corps de pré filtre l'une par rapport à l'autre étant réglable en rotation l'une par rapport à l'autre selon plusieurs positions, de préférence dans au moins 3 positions différentes, de préférence encore au moins 4 positions différentes, de préférence encore selon une position quelconque.
To solve this problem, the present invention provides a pump hydraulic portion body comprising a pre-filter body characterized in that said pre-filter body comprises:
  • an upper part comprising a wall comprising said suction port, and a second large lower port, and
  • a lower part comprising a peripheral wall comprising a third large upper orifice communicating with said second large lower orifice, preferably of the same circular dimension as the latter, and a lateral orifice communicating or being able to communicate laterally with said body of said envelope; turbine, and
  • said upper part and lower part of said pre-filter body are independent of each other and mounted in sealingly removable attachment at the peripheral edges of said second and third large openings, preferably of the same circular sections, so that they coincide one against the other by fixing, the orientation of the two said upper parts and lower part of the pre-filter body relative to each other being adjustable in rotation relative to the another according to a plurality of positions, preferably in at least 3 different positions, more preferably at least 4 different positions, more preferably in any one position.

On comprend qu'il s'agit d'une rotation par rapport à un axe perpendiculaire à un plan de raccordement virtuel ou réel desdits deuxième et troisième grands orifices, ceux-ci pouvant avoir des rebords périphériques de même forme ou de forme complémentaire.It is understood that it is a rotation with respect to an axis perpendicular to a virtual or real connection plane of said second and third large openings, which may have peripheral edges of the same shape or complementary shape.

Ainsi il est possible de modifier l'orientation dudit orifice d'aspiration pour faciliter le raccordement de celui-ci avec ledit tuyau d'arrivée d'eau provenant d'une piscine lorsque l'orifice de refoulement est raccordé avec un tuyau conduisant l'eau vers le filtre à sable.Thus it is possible to change the orientation of said suction port to facilitate connection thereof with said water inlet pipe from a pool when the discharge port is connected with a pipe leading the water to the sand filter.

La présente invention permet donc d'augmenter le débit de la pompe et de diminuer le temps pour l'installation de la pompe, en réduisant les coûts d'éventuels nécessaires pour amener le tuyau rigide d'arrivée d'eau à l'orifice d'aspiration du corps de pré filtre.The present invention therefore makes it possible to increase the flow rate of the pump and to reduce the time for the installation of the pump, by reducing the costs of any necessary to bring the rigid pipe of water supply to the orifice of the pump. suction of the pre-filter body.

On passe d'une position à l'autre en décalant en rotation d'un angle égal à un multiple de l'angle entre deux dits petits orifices consécutifs, l'une des deux dites partie supérieure et partie inférieure du corps de pré filtre par rapport à l'autre.More particularly, said orifices are small circular orifices adapted to receive a said screw and the orientation of one of said two upper part and lower part of the pre-filter body relative to the other part, being adjustable in rotation according to a a limited number of positions, preferably in at least 3 different positions, more preferably at least 4 different positions, more preferably at least 12 positions, corresponding to the number of said small holes in each said peripheral rim. We move from one position to another shifting in rotation by an angle equal to a multiple of the angle between two said small consecutive orifices, one of said two upper and lower part of the pre-filter body relative to the other.

Selon une autre variante, lesdits orifices sont des fentes s'étendant suivant une direction en arc de cercle sur une portion desdits rebords périphériques circulaires, lesdites fentes s'étendant sur un secteur angulaire. On comprend que l'orientation d'une des deux dites partie supérieure et partie inférieure dudit corps de pré filtre par rapport à l'autre est réglable en rotation par décalage angulaire de ladite partie supérieure ou partie inférieure par rapport à l'autre, les vis restant dans les mêmes fentes, ou par décalage impliquant que lesdites vis occupent des fentes différentes avant et après décalage de ladite partie supérieure ou partie inférieure. La mise en oeuvre de ces fentes permet donc d'opérer un réglage plus précis et plus fin de l'orientation des deux dites parties supérieure et inférieure l'une par rapport à l'autre.According to another variant, said orifices are slots extending in a circular arc direction on a portion of said circular peripheral rims, said slots extending over an angular sector. It will be understood that the orientation of one of said two upper and lower portions of said pre-filter body relative to the other is adjustable in rotation by angular displacement of said upper part or lower part relative to the other, the screw remaining in the same slots, or shift implying that said screws occupy different slots before and after shift of said upper part or lower part. The implementation of these slots makes it possible to operate a more precise and finer adjustment of the orientation of the two said upper and lower parts relative to each other.

On comprend que les deux méplats sont réunis par deux arcs de cercle.Preferably, said upper portion comprises a tubular wall with a partly circular section, comprising two diametrically opposite flats at the fastening elements of said cover. We understand that the two flats are joined by two circular arcs.

Ce mode de réalisation permet de pouvoir rapprocher l'orifice de refoulement du corps d'enveloppe de turbine, sans que les éléments de fixation du couvercle ne viennent le heurter lorsque ledit couvercle est décalé en rotation avec lesdits éléments de fixation au regard dudit orifice de refoulement.This embodiment makes it possible to bring the discharge orifice of the turbine casing body closer, without the fastening elements of the cover coming to strike it when said cover is rotated in rotation with said fastening elements with respect to said orifice of the casing. discharge.

Sur les figures 1 et 2, on a représenté des vues de dessus des différents éléments d'une installation de pompage et filtration dans un local technique 11, comprenant :

  • un filtre à sable 8 doté d'une vanne 6 voies 9,
  • une canalisation d'arrivée d'eau 6 provenant de la piscine, et
  • une installation de pompage et pré filtration 10 en amont du filtre à sable (8).
On the Figures 1 and 2 , top views of the various elements of a pumping and filtration installation are shown in a technical room 11, comprising:
  • a sand filter 8 with a 6-way valve 9,
  • a water supply pipe 6 coming from the pool, and
  • a pumping and pre-filtration plant 10 upstream of the sand filter (8).

Sur la figure 1, l'installation de pompage et pré filtration 10 comprend :

  1. a- un corps de pré filtre selon la technique antérieure 1'a, comprenant un orifice d'aspiration 2a de l'eau provenant de la conduite 6, ce corps de pré filtre 1'a étant un corps monobloc, l'orifice d'aspiration 2a étant positionné de façon inamovible dans l'axe général de l'installation (axe de la turbine et axe du moteur 1c),

L'ensemble du corps de pré filtre 1'a et du corps d'enveloppe de turbine 1b constitue ce que l'on appelle le corps de partie hydraulique de l'installation 10.The entire pre-filter body 1'a and turbine casing body 1b constitutes the so-called hydraulic part body of the plant 10.

Sur la figure 2, on a représenté une installation similaire à celle de la figure 1, avec la différence que l'on a mis en oeuvre un corps de pré filtre 1a selon la présente invention, de sorte que l'embout correspondant à l'orifice d'aspiration 2a du corps de pré filtre, a été pivoté à 90° par rapport à un axe vertical du corps de pré filtre. Ceci a permis d'atteindre le point d'arrivée 6a de la conduite d'eau 6 dans le local technique, sans faire de coude, ce qui représente un gain de temps pour la mise en place de l'installation de pompage et de pré filtration et un gain de débit ou rendement en opération.On the figure 2 , there is shown an installation similar to that of the figure 1 with the difference that a pre-filter body 1a according to the present invention has been implemented, so that the tip corresponding to the suction port 2a of the pre-filter body has been rotated by 90 ° relative to a vertical axis of the pre-filter body. This made it possible to reach the end point 6a of the water pipe 6 in the technical room, without making an elbow, which represents a saving of time for the installation of the pumping and meadow installation. filtration and a gain of flow or yield in operation.

Dans le mode de réalisation des figures 3 à 6, le corps de pré filtre 1a est indépendant du corps d'enveloppe de turbine 1b, avec lequel il est apte à coopérer en fixation amovible, comme il sera décrit ci-après.In the embodiment of Figures 3 to 6 , the pre-filter body 1a is independent of the turbine casing body 1b, with which it is adapted to cooperate in removable attachment, as will be described below.

Sur les figures 3 et 4, on a représenté une première variante de réalisation d'un corps de pré filtre comme décrit ci-après.On the figures 3 and 4 , there is shown a first embodiment of a pre-filter body as described below.

Sur les figures 3 à 6, le corps de pré filtre 1a comprend une partie inférieure 3, laquelle comprend une paroi périphérique tubulaire 3b à section circulaire dont l'extrémité supérieure délimite un grand orifice supérieur 3c dénommé "troisième grand orifice supérieur 3c", et dont l'extrémité inférieure est fermée par un fond 3e pour former un réceptacle d'un panier de filtration 5. La paroi tubulaire 3b comprend un orifice latéral 3a formé par un embout tubulaire 3-1. Cet embout latéral 3-1 formant un orifice 3a est apte à coopérer en fixation amovible avec un orifice latéral correspondant du corps d'enveloppe de turbine 1b au niveau de son rebord périphérique respectif 3-2.On the Figures 3 to 6 , the pre-filter body 1a comprises a lower part 3, which comprises a tubular peripheral wall 3b with a circular cross-section whose upper end delimits a large upper orifice 3c called "third large upper orifice 3c", and whose lower end is closed by a third bottom to form a receptacle of a filter basket 5. The tubular wall 3b comprises a lateral orifice 3a formed by a tubular nozzle 3-1. This lateral end 3-1 forming an orifice 3a is adapted to cooperate in removable attachment with a corresponding lateral orifice of the turbine casing body 1b at its respective peripheral rim 3-2.

Le troisième grand orifice supérieur 3c de ladite partie inférieure 3 comprend un rebord périphérique 3d avec une rainure circulaire 6d sur sa face supérieure, dans laquelle on peut loger un joint torique élastomère 6a. A l'extérieur de la rainure 6d et du joint torique 6a, sont disposés régulièrement espacés les uns des autres une pluralité (12) de perforations 6e qui permettent de fixer l'une à l'autre ladite partie inférieure 3 et une partie supérieure 2 du corps de pré filtre, comme il sera décrit ci-après, à l'aide de vis 6b et boulons 6c.The third large upper orifice 3c of said lower portion 3 comprises a peripheral rim 3d with a circular groove 6d on its upper face, in which an elastomeric O-ring 6a can be housed.

La partie supérieure 2 du corps de pré filtre comprend une paroi tubulaire à section circulaire 2b comprenant un embout latéral 2-1 formant un orifice d'aspiration 2a, et délimitant à ses extrémités supérieure et inférieure des premier grand orifice supérieur 2c et, respectivement, deuxième grand orifice inférieur 2d.The upper part 2 of the pre-filter body comprises a tubular wall with circular section 2b comprising a lateral end 2-1 forming a suction orifice 2a, and delimiting at its upper and lower ends first large upper orifice 2c and, respectively, second large lower port 2d.

Ledit deuxième grand orifice inférieur 2d est entouré par un rebord périphérique 2e de même forme plate et circulaire que le rebord périphérique 3d dudit troisième grand orifice supérieur 3c de la partie inférieure 3. Ces rebords périphériques 2e et 3d comprennent également un même nombre de perforations 6e.Said second large lower orifice 2d is surrounded by a peripheral rim 2e of the same flat and circular shape as the peripheral edge 3d of said third large upper orifice 3c of the lower part 3. These peripheral rims 2e and 3d also comprise the same number of perforations. .

Les trois dits premier, deuxième et troisième grands orifices ont le même diamètre, de sorte qu'il est possible de rentrer ou sortir le panier 5 par le haut, lorsque l'on ouvre le couvercle 4 comme il sera exposé plus loin.The three said first, second and third large openings have the same diameter, so that it is possible to enter or exit the basket 5 from above, when the lid 4 is opened as will be explained later.

Lesdites partie supérieure 2 et partie inférieure 3 dudit corps de pré filtre sont montées en fixation dans un plan de raccordement 6 au niveau des premiers rebords périphériques 2e, 3d, desdits deuxième et troisième grands orifices 2d, 3c, de manière à ce que lesdits rebords périphériques desdits deuxième grand orifice inférieur 2d et troisième grand orifice supérieur 3c s'adaptent l'un contre l'autre, ladite fixation des deux dites partie supérieure 2 et partie inférieure 3 du corps de pré filtre au niveau des deux dits rebords périphériques 2e, 3d, étant orientable en rotation dans ledit plan de raccordement 6, de façon variable l'un par rapport à l'autre, par décalage angulaire de 30°, soit selon 12 positions différentes, selon l'orientation que l'on veut donner à l'orifice d'aspiration 2a selon la position d'arrivée 6a dans le local technique du conduit de circulation d'eau 6.Said upper part 2 and lower part 3 of said pre-filter body are fixedly mounted in a connection plane 6 at the first peripheral edges 2e, 3d, of said second and third large orifices 2d, 3c, so that said peripheral rims of said second large lower orifice 2d and third large upper orifice 3c fit one against the other, said attachment of both said upper part 2 and lower part 3 of the pre-filter body at the two said peripheral edges 2e, 3d, being rotatable in said connection plane 6, in a variable manner relative to each other, by angular offset of 30 °, or in 12 positions different, depending on the orientation that is to be given to the suction port 2a according to the arrival position 6a in the technical room of the water circulation duct 6.

Le premier grand orifice supérieur 2c de la partie supérieur 2 comprend un rebord périphérique 2g, avec une rainure circulaire 4e sur sa face externe supérieure dans laquelle on peut loger un joint torique élastomère d'étanchéité 4a assurant l'étanchéité avec le couvercle 4.The first large upper orifice 2c of the upper part 2 comprises a peripheral rim 2g, with a circular groove 4e on its upper outer face in which an elastomeric sealing O-ring 4a can be housed, sealing the lid 4.

La paroi périphérique tubulaire 2b comprend deux étriers externes 2f diamétralement opposés pour la fixation du couvercle 4. Le couvercle 4 comprend également deux encoches latérales diamétralement opposées 4c. Les encoches 4c et étriers 2f permettent la fixation étanche et amovible du couvercle 4 sur le rebord périphérique 2g du premier grand orifice supérieur 2c, à l'aide de vis 4b équipées de petits blocs tubulaires de fixation 4g. Ces blocs 4g comprennent une perforation avec pas de vis, de sorte que le vissage de la tige filetée 4d des vis de fixation 4b permet, lorsque le petit bloc tubulaire 4g est inséré dans des perforations 2h s'étendant transversalement à travers les deux branches formant l'étrier 2f, de fixer par serrage le couvercle 4 contre le rebord périphérique 2g de la partie supérieure 2 du corps de pré filtre lorsque des vis de fixation 4b sont logés dans les encoches 4c du couvercle, puis la tige filetée 4d des vis 4b est vissée dans la perforation du petit bloc tubulaire 4g à l'aide des boutons 4h des vis 4b retenus par les encoches 4c.The tubular peripheral wall 2b comprises two diametrically opposed external stirrups 2f for fixing the cover 4. The cover 4 also comprises two diametrically opposite lateral notches 4c. The notches 4c and 2f stirrups allow the waterproof and removable attachment of the cover 4 on the peripheral rim 2g of the first large upper orifice 2c, using screws 4b equipped with small tubular fixing blocks 4g. These blocks 4g comprise a perforation with screw thread, so that the screwing of the threaded rod 4d of the fixing screws 4b allows, when the small tubular block 4g is inserted into perforations 2h extending transversely through the two branches forming the stirrup 2f, clamping the cover 4 against the peripheral flange 2g of the upper part 2 of the pre-filter body when fixing screws 4b are housed in the notches 4c of the cover, then the threaded rod 4d of the screws 4b is screwed into the perforation of the small tubular block 4g using 4h buttons 4b screws retained by the notches 4c.

Le mode de réalisation des figures 5 et 6 diffère de celui des figures 3 et 4 par le mode de fixation desdites partie supérieure 2 et partie inférieure 5. Dans les figures 5 et 6, on met en oeuvre deux demi colliers 6g dont les extrémités 6h sont diamétralement opposées, c'est-à-dire que chaque demi collier parcourt un demi cercle. Sur la face interne de chaque demi collier, une rainure 6i permet de bloquer l'un contre l'autre les rebords périphériques 2e et 3d desdits deuxième grand orifice inférieur 2d et troisième grand orifice supérieur 3c qui viennent se loger dans ladite rainure 6i, lorsque l'on serre l'un contre l'autre les deux demi colliers de serrage 6g. les extrémités 6h bout à bout de chaque demi collier comportent une perforation 6j, dans laquelle on peut insérer des vis 6k dans une perforation 6j d'un premier demi collier coopérant avec des boulons 61 à l'extérieur de la perforation 6j du deuxième demi collier.The embodiment of the figures 5 and 6 differs from that of figures 3 and 4 by the method of fixing said upper part 2 and part 5. In the figures 5 and 6 two half collars 6g are used whose ends 6h are diametrically opposite, that is to say that each half-collar travels a half-circle. On the inner face of each half-collar, a groove 6i makes it possible to block one against the other the peripheral edges 2e and 3d of said second large lower orifice 2d and third greater upper orifice 3c which are housed in said groove 6i, when the two half clamps 6g are tightened against each other. the ends 6h end to end of each half collar comprise a perforation 6j, in which screws 6k can be inserted into a perforation 6j of a first half-collar cooperating with bolts 61 outside the perforation 6j of the second half-collar .

Sur les figures 7 et 8 on a représenté un dispositif de pré filtration et pompage 10 avec un corps de pré filtre 1a coopérant avec un corps d'enveloppe de turbine 1b renfermant une turbine 7 comprenant des aubes à palettes ou à ailettes, coopérant avec un moteur électrique 1c, de manière à pouvoir l'entraîner en rotation. La partie inférieure 3 du corps de pré filtre comporte un orifice de communication 3a qui communique avec un orifice 7a du corps de d'enveloppe de turbine. L'orifice latéral 3a du corps de pré filtre est formé par un embout tubulaire 3-1 qui vient s'emmancher à l'intérieur de l'orifice tubulaire 7a du corps d'enveloppe de turbine. Plus précisément, le rebord périphérique externe 3-2 de l'embout tubulaire 3-1 vient buter sur un rebord périphérique interne d'une butée interne 7-1 de l'orifice latéral 7a du corps d'enveloppe de turbine. Ledit corps d'enveloppe de turbine 1c comporte un flasque de raccordement 7b apte à coopérer avec un flasque de raccordement correspondant 10a d'un corps de moteur électrique 1c de la pompe 10.On the Figures 7 and 8 there is shown a pre-filtration and pumping device 10 with a pre-filter body 1a cooperating with a turbine casing body 1b enclosing a turbine 7 comprising vanes with vanes or blades, cooperating with an electric motor 1c, so as to to be able to drive it in rotation. The lower portion 3 of the pre-filter body has a communication port 3a which communicates with an orifice 7a of the turbine casing body. The lateral orifice 3a of the pre-filter body is formed by a tubular nozzle 3-1 which is engaged within the tubular orifice 7a of the turbine casing body. More specifically, the outer peripheral rim 3-2 of the tubular nozzle 3-1 abuts on an inner peripheral rim of an internal stop 7-1 of the lateral orifice 7a of the turbine casing body. Said turbine casing body 1c comprises a connecting flange 7b adapted to cooperate with a corresponding connection flange 10a of an electric motor body 1c of the pump 10.

Sur la figure 9, on a représenté un corps de pré filtre, dans lequel les partie inférieure 3 et partie supérieure 2 sont fixées l'une à l'autre à l'aide d'une bride de serrage 6n contenant, sur sa face interne, un filetage femelle apte à coopérer avec un filetage mâle sur la périphérie dudit troisième grand orifice supérieur 3c de la partie inférieure 3, à l'extrémité supérieure de ladite partie inférieure 3. Plus précisément, la bride de serrage 6n vient plaquer le rebord périphérique 2e entourant le deuxième grand orifice inférieur 2d de la partie supérieure 2, et le filetage mâle coopérant avec le filetage femelle interne de ladite bride de serrage 6n, est réalisé sur la face externe périphérique du rebord périphérique 3d entourant ledit troisième grand orifice supérieur 3c.On the figure 9 , there is shown a pre-filter body, in which the lower part 3 and the upper part 2 are fixed to each other by means of a clamping flange 6n containing, on its internal face, a female thread. adapted to cooperate with a male thread on the periphery of said third large upper orifice 3c of the lower part 3, at the upper end of said lower part 3. More precisely, the clamping flange 6n comes plating the peripheral flange 2e surrounding the second large lower orifice 2d of the upper part 2, and the male thread cooperating with the internal female thread of said clamping flange 6n, is formed on the peripheral outer face of the peripheral flange 3d surrounding said third major upper orifice 3c.

De même, sur la figure 9, on a représenté un mode de réalisation dans lequel le couvercle 4 du premier grand orifice supérieur de sortie de panier 2c est fixé sur ledit premier grand orifice supérieur 2c par serrage en faisant coopérer un filetage périphérique interne femelle dudit couvercle avec un filetage périphérique externe mâle autour dudit premier grand orifice supérieur 2c dudit corps de pré filtre 1a.Similarly, on the figure 9 there is shown an embodiment in which the lid 4 of the first large upper basket outlet orifice 2c is fixed on said first large upper orifice 2c by clamping by cooperating a female internal peripheral thread of said lid with a male external peripheral thread. around said first large upper orifice 2c of said pre-filter body 1a.

Sur la figure 10, on a représenté une variante avantageuse de réalisation de la partie supérieure 2 du corps de partie hydraulique de pompe, dans laquelle les petits orifices 6e du rebord 2e de l'extrémité inférieure de la paroi tubulaire 2b, entourant ledit deuxième grand orifice inférieur 2d, sont remplacés par des fentes 6f s'étendant sur une portion dudit rebord circulaire sur un secteur angulaire donné.On the figure 10 , there is shown an advantageous variant of embodiment of the upper part 2 of the pump hydraulic part body, in which the small orifices 6e of the 2nd edge of the lower end of the tubular wall 2b, surrounding said second large lower orifice 2d, are replaced by slots 6f extending over a portion of said circular flange on a given angular sector.

On comprend que le rebord périphérique 3d, entourant ledit troisième grand orifice supérieur 3c de la partie inférieure 3, doit comporter les mêmes fentes, en même nombre, disposées en coïncidence avec celles du rebord périphérique 2e de la partie supérieure 2.It is understood that the peripheral flange 3d, surrounding said third large upper orifice 3c of the lower part 3, must comprise the same slots, in the same number, arranged in coincidence with those of the peripheral flange 2e of the upper part 2.

Cette variante de réalisation permet d'opérer des réglages angulaires plus précis et plus fins, permettant le décalage de la partie supérieure 2 par rapport à la partie inférieure, sans avoir à déplacer les vis 6b d'une fente à l'autre dudit rebord périphérique 2e de la partie supérieure 2.This variant embodiment makes it possible to operate more precise and finer angular adjustments, allowing the upper part 2 to be shifted relative to the lower part, without having to move the screws 6b from one slot to the other of said peripheral flange. 2nd of the upper part 2.

Sur la figure 10, on a également représenté une paroi tubulaire 2b comportant une section circulaire partielle avec deux méplats 2k, diamétralement opposés au niveau des éléments de fixation 2f du couvercle 4. Ce mode de réalisation est avantageux car il permet de diminuer la distance entre l'orifice de refoulement 1d, sans que les éléments de fixation du couvercle 2f ne viennent buter dessus lorsque la partie supérieure 2 et le couvercle 4 sont décalés en rotation avec lesdits éléments de fixation 2f au regard dudit orifice de refoulement 1d du corps d'enveloppe de turbine 1b.On the figure 10 a tubular wall 2b having a partial circular section with two flat surfaces 2k diametrically opposite at the level of the fastening elements 2f of the cover 4 is also shown. This embodiment is advantageous because it makes it possible to reduce the distance between the discharge 1d, without the fastening elements 2f of the lid do not abut when the upper portion 2 and the lid 4 are offset in rotation with said fasteners 2f with respect to said discharge port 1d of the turbine casing body 1b.

Sur la figure 11, on a représenté une variante de réalisation d'un corps de partie hydraulique de pompe dont la partie inférieure 3 du corps de pré filtre forme un corps monobloc avec ledit corps d'enveloppe 1c de turbine avec lequel elle communique au niveau de l'orifice latéral 3a de ladite paroi périphérique 3b du réceptacle de la partie inférieure 3. Le corps d'enveloppe de turbine 1b renferme la turbine 7 et le moteur 1c, représenté sur la figure 12, vient se plaquer contre le flasque 7bOn the figure 11 , there is shown an alternative embodiment of a pump hydraulic portion body whose lower part 3 of the pre-filter body forms a one-piece body with said turbine casing body 1c with which it communicates at the orifice side 3a of said peripheral wall 3b of the receptacle of the lower portion 3. The turbine casing body 1b encloses the turbine 7 and the motor 1c, shown in FIG. figure 12 , comes to flatten against flange 7b
