An axis (X2, X'2) of the end-piece is inclined relative to an axis of the ball such that the axis of the end-piece pivots in all directions of an angle (alpha) relative to an axis (XX') of a delivery orifice (1b) or a suction orifice of the pump. The angle is varied from less than alpha-max to more than alpha-max in a range of about 30 to 45 degrees. An independent claim is also included for a water flow installation for a swimming pool, comprising a filtration pump or counter-current swimming pump.

Description

La présente invention concerne une pompe hydraulique de piscine comprenant des raccords de connexion à une tuyauterie de circulation d'un fluide, de préférence de piscine ou bassin, au niveau de l'orifice d'aspiration de fluide de la pompe et/ou de l'orifice de refoulement de fluide de la pompe.The present invention relates to a hydraulic pool pump comprising connections for connection to a pipe for circulating a fluid, preferably a pool or pond, at the level of the fluid suction orifice of the pump and / or the fluid discharge port of the pump.

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 et affecte négativement l'hydraulicité et le rendement de la pompe.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, sometimes necessary to provide many elbows to match the water inlet pipe coming from the pool from the surface suction skimmer or the bottom drain or other suction of water from the pool. the pool and the suction port, which not only sometimes poses difficulties of space, but also affects the efficiency of the pump. Indeed, the multiplicity of elbows inevitably induces loss of load and negatively affects the hydraulicity and efficiency of the pump.

Pour résoudre ce problème, la présente invention fournit une pompe hydraulique de piscine comprenant des raccords de connexion à une tuyauterie de circulation d'un fluide, de préférence de piscine ou bassin au niveau de l'orifice d'aspiration de fluide de la pompe et/ou de l'orifice de refoulement de fluide de la pompe, ladite pompe comprenant au moins un dit raccord de connexion intégré à la pompe au niveau d'un dit orifice de refoulement ou dit orifice d'aspiration, ledit raccord comprenant une rotule sphérique se terminant par un embout tubulaire cylindrique apte à s'emmancher à l'extrémité d'un dit tuyau de circulation de fluide, caractérisé en ce que l'axe X2X'2 dudit embout cylindrique est incliné par rapport à l'axe X1X'1 de ladite rotule sphérique, de sorte que l'axe X2X'2 dudit embout cylindrique peut pivoter dans toutes les directions de rotation par rapport à l'axe XX' dudit orifice de refoulement et/ou d'aspiration de la pompe, et présente une inclinaison par rapport à l'axe XX' dudit orifice de la pompe, d'un angle α inférieur ou égal en valeur absolue à αmax, αmax étant de 25° à 60°, de préférence de 30° à 45°.To solve this problem, the present invention provides a swimming pool hydraulic pump comprising connectors for connection to a flow pipe of a fluid, preferably a pool or pond at the fluid suction port of the pump and / or the fluid discharge port of the pump, said pump comprising at least one said connection fitting integrated with the pump at a said discharge port or said suction port, said coupling comprising a spherical ball joint terminating in a cylindrical tubular tip adapted to engage at the end of a said fluid circulation pipe, characterized in that the axis X 2 X ' 2 of said cylindrical tip is inclined with respect to the X axis 1 X ' 1 of said spherical ball joint, so that the axis X 2 X' 2 of said cylindrical nozzle can pivot in all directions of rotation with respect to the axis XX 'of said delivery port and / or suction port of the pump, and presents a inclination with respect to the axis XX 'of said pump orifice, of an angle α less than or equal to an absolute value at α max, α max being from 25 ° to 60 °, preferably from 30 ° to 45 °.

On comprend donc que l'axe X2X'2 dudit embout cylindrique de la pompe peut pivoter par rapport à l'axe dudit orifice de refoulement ou orifice d'aspiration dans un cône de demi angle au sommet de valeur αmax, c'est-à-dire que l'axe X2X'2 de l'embout cylindrique peut pivoter, dans une orientation donnée en rotation du plan comprenant lesdits axe X2X'2 et l'axe XX' de l'orifice de la pompe, d'une valeur de -αmax à +αmax.It is therefore understood that the axis X 2 X ' 2 of said cylindrical nozzle of the pump can pivot relative to the axis of said discharge orifice or suction orifice in a cone of half angle at the vertex of value αmax. that is, the axis X 2 X ' 2 of the cylindrical endpiece can pivot in a given orientation in rotation of the plane comprising said axis X 2 X' 2 and the axis XX 'of the orifice of the pump , from a value of -αmax to + αmax.

Cette possibilité de pivotement dudit embout cylindrique au niveau de l'orifice de la pompe, rend beaucoup plus aisé le raccordement de la pompe à une installation de tuyauterie de circulation, notamment dans un local technique. En effet, les directions d'arrivée desdites tuyauteries au niveau de la pompe, sont déterminées par la localisation de la piscine et/ou du matériel tel que le filtre à sable auquel est assujettie la pompe. Or, un décalage de seulement quelques degrés peut rendre nécessaire la mise en oeuvre de plusieurs coudes dans les canalisation pour rattraper ce décalage et que l'axe du tuyau de circulation d'eau à son extrémité de raccordement coïncide avec l'axe de l'embout cylindrique.This possibility of pivoting said cylindrical nozzle at the orifice of the pump, makes it much easier to connect the pump to a circulation pipe installation, especially in a technical room. Indeed, the directions of arrival of said pipes at the pump, are determined by the location of the pool and / or equipment such as the sand filter which is subject the pump. However, an offset of only a few degrees may make it necessary to implement several bends in the pipe to make up for this offset and that the axis of the water circulation pipe at its connecting end coincides with the axis of the cylindrical tip.

D'autre part, la limitation de l'angle de pivotement d'une valeur de 25° à 60° et, de préférence, d'environ de 30 à 45°, permet de conserver une hydraulicité acceptable du fluide circulant à travers l'orifice et les tuyaux de circulation d'eau au niveau de leur raccordement afin de ne pas affecter les performances de débit de la pompe.On the other hand, the limitation of the pivoting angle from 25 ° to 60 ° and preferably from approximately 30 ° to 45 °, makes it possible to maintain an acceptable fluidity of the fluid flowing through the orifice and the water circulation pipes at their connection so as not to affect the flow performance of the pump.

D'une manière générale, la possibilité d'éviter un certain nombre de variations angulaires importantes des tuyaux, notamment des coudes dans le trajet de la tuyauterie de circulation d'eau contribue à améliorer les performances de débit de la pompe pour un moteur donné en diminuant les pertes de charge.In general, the possibility of avoiding a number of significant angular variations of the pipes, especially elbows in the path of the water circulation piping, contributes to improving the flow performance of the pump for a given engine in a particular manner. decreasing the pressure drops.

Les inclinaisons respectives de l'embout cylindrique et de l'angle de pivotement de la rotule sphérique permettent ainsi de combiner une variation angulaire relativement importante, l'inclinaison de l'embout cylindrique par rapport à l'axe de la rotule sphérique et l'angle de pivotement possible de la rotule sphérique par rapport à l'axe de l'orifice de la pompe permettent d'obtenir une variation angulaire d'un angle relativement important de l'embout cylindrique par rapport à l'axe de l'orifice de la pompe sans nécessiter de rotation excessive de la rotule sphérique, ce qui permet de préserver des conditions d'hydraulicité satisfaisantes, ainsi que des conditions d'étanchéité satisfaisantes en ce qui concerne la circulation du fluide dans le raccord à rotule sphérique.The respective inclinations of the cylindrical endpiece and the pivot angle of the spherical joint make it possible to combine a relatively large angular variation, the inclination of the cylindrical tip relative to the axis of the spherical ball and the possible pivot angle of the spherical ball with respect to the axis of the pump orifice allow to to obtain an angular variation of a relatively large angle of the cylindrical nozzle with respect to the axis of the orifice of the pump without requiring excessive rotation of the spherical ball joint, which makes it possible to preserve satisfactory hydraulic conditions, as well as satisfactory sealing conditions with regard to the flow of fluid in the spherical ball joint.

Dans un mode préféré de réalisation, l'axe X2X'2 dudit embout cylindrique dénommé deuxième axe est incliné d'un angle fixe α2 ayant une valeur de 10° à 30°, de préférence 10° à 20°, par rapport à l'axe X1X'1 de ladite rotule sphérique, dénommé premier axe, et ladite rotule sphérique peut pivoter d'un angle α1 de -α1max à +α1max entre son dit premier axe X1X'1 et l'axe de l'orifice de la pompe XX' dans toute direction de rotation par rapport à l'axe XX' de l'orifice de la pompe, α1max étant de 15° à 30°, de préférence 15° à 25°, de sorte que l'axe X2X'2 dudit embout cylindrique peut pivoter par rapport à un axe perpendiculaire à l'axe XX' dudit orifice de la pompe d'une valeur de -|α1 max-α2| à (α1 max+α2) dans un plan donné passant pas lesdits premier et deuxième axes X1X'1 et X2X'2, dans une direction de rotation donnée fixe par rapport à l'axe XX' dudit orifice de la pompe.In a preferred embodiment, the axis X 2 X ' 2 of said cylindrical nozzle called second axis is inclined at a fixed angle α 2 having a value of 10 ° to 30 °, preferably 10 ° to 20 °, relative to to the axis X 1 X ' 1 of said spherical ball joint, referred to as the first axis, and said spherical ball joint can pivot by an angle α 1 from -α 1 max to + α 1 max between said first axis X 1 X' 1 and the axis of the orifice of the pump XX 'in any direction of rotation relative to the axis XX' of the orifice of the pump, α 1 max being from 15 ° to 30 °, preferably 15 ° to 25 °, so that the axis X 2 X ' 2 of said cylindrical nozzle can pivot relative to an axis perpendicular to the axis XX' of said pump orifice by a value of - | α 1 max-α 2 | to (α 1 max + α 2 ) in a given plane passing through said first and second axes X 1 X ' 1 and X 2 X' 2 , in a given direction of rotation relative to the axis XX 'of said orifice the pump.

Plus particulièrement, l'angle α1max est sensiblement égal audit angle α2 d'une valeur de 15° à 25°, de préférence d'une valeur de 22,5°.More particularly, the angle α 1 max is substantially equal to said angle α 2 of a value of 15 ° to 25 °, preferably of a value of 22.5 °.

On comprend en effet qu'avec un pivotement trop important de la rotule sphérique, il devient difficile de conserver l'étanchéité de celle-ci, notamment dans le cadre d'un raccord démontable tel que décrit ci-après en effet, si l'angle de rotation αmax ou α1max de la rotule sphérique est trop important, la portée de la rotule sphérique sur une surface d'appui concave contre laquelle elle glisse en rotation sera insuffisante au regard de l'étanchéité du raccord si par ailleurs, afin de préserver l'hydraulicité, l'extrémité de la rotule sphérique n'empiète pas sur les ouvertures de passage de l'eau au regard de la pompe.It is understood in fact that with excessive pivoting of the spherical ball joint, it becomes difficult to maintain the tightness thereof, particularly in the context of a removable connection as described hereinafter indeed, if the angle of rotation αmax or α 1 max of the spherical ball is too large, the range of the spherical ball on a concave bearing surface against which it slides in rotation will be insufficient in view of the sealing of the connection if, moreover, in order to preserve the hydraulicity, the end of the spherical ball joint does not impinge on the openings for the passage of water with respect to the pump.

Dans une variante de réalisation avantageuse, la pompe est caractérisée en ce que :

Plus particulièrement, ledit raccord à rotule sphérique comprend une dite surface concave sphérique séparée en deux parties au niveau d'un troisième plan de section de sorte que ladite pièce d'appui comprend une première partie de pièce d'appui inférieure comprenant une première surface concave sphérique autour dudit orifice de la pompe, par-dessus laquelle vient en appui une deuxième partie de pièce d'appui supérieure en forme de collerette dont la deuxième surface concave sphérique est en continuité de ladite première surface concave sphérique, ladite deuxième partie de pièce d'appui supérieure en forme de collerette étant maintenue de manière étanche à l'aide d'un joint torique contre ladite première partie de pièce d'appui inférieure par un collier de serrage.More particularly, said spherical ball joint comprises a said spherical concave surface divided into two parts at a third sectional plane so that said support piece comprises a first lower part portion comprising a first concave surface spherical around said pump orifice, over which rests a second part of upper support piece in the form of a flange whose second concave spherical surface is in continuity with said first spherical concave surface, said second part of the spherical concave surface flange-shaped upper support being sealingly held by an O-ring against said first lower bearing part portion by a clamping collar.

Dans un mode préféré de réalisation, la cavité interne tronconique présente une génératrice droite inclinée d'un angle α3 de 20° à 30°, de préférence environ 25° par rapport au dit premier axe de révolution X1X'1.In a preferred embodiment, the frustoconical internal cavity has a straight generatrix inclined at an angle α 3 of 20 ° to 30 °, preferably about 25 ° relative to said first axis of revolution X 1 X ' 1 .

  • the figure 8 represents a spherical ball 210 of a connection according to the invention in sectional view.

Dans les figures, on a représenté une pompe de nage à contre-courant 1, comprenant une partie avec son moteur électrique 10a, qui coopère avec une partie hydraulique 10b contenant une aube interne (non représentée), coiffée par un capot métallique 1c comprenant deux orifices, à savoir un orifice axial 1b correspondant à un orifice d'aspiration de l'eau provenant d'une canalisation d'arrivée d'eau 101, et un orifice latéral 1a, ou orifice de refoulement, permettant le refoulement dans une direction tangentielle, par rapport au mouvement circulaire de circulation d'eau à l'intérieur du capot 1c à section circulaire, de l'eau dans une canalisation 102.In the figures, there is shown a counter-current swimming pump 1, comprising a part with its electric motor 10a, which cooperates with a hydraulic part 10b containing an internal blade (not shown), capped by a metal cap 1c comprising two orifices, namely an axial orifice 1b corresponding to a water suction port from a water inlet pipe 10 1 , and a lateral orifice 1a, or discharge port, allowing the discharge in one direction tangential, compared to the circular movement of water circulating inside the hood 1c circular section, water in a pipe 10 2 .

Sur la figure 1B, on voit qu'en l'absence de raccord à rotule sphérique selon l'invention, le montage des tuyaux 101, 102 peut nécessiter la mise en oeuvre de raccords tubulaires coudés 11a ou raccord à portion de conduite inclinée par rapport à ses extrémités 11b, pour arriver dans l'axe des orifices 1a et 1b de la pompe 1d.On the Figure 1B it can be seen that, in the absence of a spherical ball joint according to the invention, the mounting of the pipes 10 1 , 10 2 may necessitate the use of angled tubular connectors 11a or an inclined pipe portion connection with respect to its ends 11b, to arrive in the axis of the orifices 1a and 1b of the pump 1d.

Sur les figures 1 et 1A, on voit que la pompe 1 selon l'invention comprend deux raccords 200a et 200b selon l'invention, comprenant des rotules sphériques 210.On the figures 1 and 1A it can be seen that the pump 1 according to the invention comprises two connectors 200a and 200b according to the invention, comprising spherical ball joints 210.

Comme représenté sur la figure 1A, lorsque la pompe est disposée sensiblement horizontalement au niveau du sol, par exemple, l'axe de symétrie de l'orifice d'aspiration est disposé sensiblement horizontalement, tandis que l'axe de symétrie dudit orifice de refoulement est disposé perpendiculairement et au-dessus dudit orifice d'aspiration. Toutefois, comme montré sur la figure 1A, les raccords à rotule sphérique selon l'invention permettent de raccorder la pompe à des arrivées 103 desdites canalisations 101 et 102 d'aspiration et de refoulement de l'eau, qui ne sont pas disposées à 90°, et ce, grâce à la rotation de la rotule sphérique desdits raccords, comme il sera expliqué ci-après.As shown on the Figure 1A when the pump is disposed substantially horizontally at ground level, for example, the axis of symmetry of the suction port is disposed substantially horizontally, while the axis of symmetry of said discharge port is disposed perpendicularly and beyond above said suction port. However, as shown on the Figure 1A , the spherical ball joints according to the invention make it possible to connect the pump to inflows 10 3 of said pipes 10 1 and 10 2 of suction and discharge of water, which are not arranged at 90 °, and this thanks to the rotation of the spherical ball of said connectors, as will be explained below.

Sur la figure 1A, les rotules sphériques 210 des raccords 200a et 200b sont pivotées dans deux positions extrêmes opposées, positions extrêmes également illustrées sur les figures 2A et 2B en ce qui concerne le raccord 200b.On the Figure 1A , the spherical hinges 210 of the connectors 200a and 200b are pivoted in two opposite extreme positions, extreme positions also illustrated on the Figures 2A and 2B with regard to the connection 200b.

Une pompe équipée de raccords à rotule sphérique selon l'invention permet qu'au moins un des tuyaux de circulation d'eau 101, 102, au niveau de son extrémité du coté du raccordement à la pompe, soit incliné de telle sorte que l'axe dudit tuyau à son extrémité 103 soit incliné par rapport à l'axe de l'orifice auquel il est relié par l'intermédiaire dudit raccord, et, lorsque les deux tuyaux d'aspiration et de refoulement sont inclinés par rapport à l'axe de symétrie de l'orifice de la pompe avec lequel ils coopèrent, l'angle d'inclinaison peut être différent dans les deux cas.A pump equipped with spherical ball joints according to the invention allows at least one of the water circulation pipes 10 1 , 10 2 , at its end on the side of the connection to the pump, to be inclined so that the axis of said pipe at its end 3 is inclined with respect to the axis of the orifice to which it is connected via said coupling, and when the two suction and discharge pipes are inclined with respect to the axis of symmetry of the orifice of the pump with which they cooperate, the angle of inclination may be different in both cases.

Un raccord à rotule sphérique selon l'invention 200a, 200b, est composé de :

  1. a- une rotule sphérique interne 210, comportant une surface externe convexe, de section sphérique, 211, surmontée par un embout tubulaire creux 230 venant dans la prolongation d'une cavité interne de passage de fluide, délimitée par une surface de révolution de type tronconique 220, ici représenté à génératrice droite, ladite cavité tronconique 220 présentant un premier axe de révolution X1X'1. Ladite cavité tronconique présente une petite base ouverte au niveau d'un premier plan de section 221 et une grande base circulaire ouverte au niveau d'un deuxième plan de section 222, les deux plans de section étant perpendiculaires à l'axe X1X'1. On comprend que ces deux plans de section 221 et 222 délimitent la section sphérique de ladite rotule sphérique 210. Ladite rotule sphérique comporte à son extrémité, du coté de ladite petite base ouverte circulaire au niveau du premier plan de section 221, un embout tubulaire cylindrique 230, dont le deuxième axe de révolution X2X'2 est incliné d'une angle α2 par rapport audit premier axe de révolution X1X'1 de ladite cavité interne tronconique 220, la cavité interne tronconique 220 se prolongeant par la cavité interne tubulaire 213 dudit embout tubulaire cylindrique. De par l'inclinaison α2 entre les deux axes X2X'2 et X1X'1, la cavité interne tubulaire 231 présente une extrémité biseautée au niveau de la petite base ouverte circulaire de la cavité interne tronconique au niveau du premier plan de section 221, et une deuxième extrémité droite apte à s'emmancher à l'extrémité d'un tuyau de circulation d'eau 101, 102.
  2. b- une pièce d'appui 240 en deux parties 240a et 240b. Cette pièce d'appui comprend une surface interne concave de section sphérique contre laquelle glisse en rotation la surface convexe externe 211 de section sphérique de la rotule sphérique. La première pièce d'appui 240a comprend une première surface concave sphérique interne 241a perforée de manière centrale 243 de manière à s'adapter au niveau d'un embout tubulaire d'orifice 1a, 1b de pompe ou directement sur l'orifice de pompe, ladite surface d'appui concave sphérique 241a-241b présentant le même axe de révolution XX' que l'orifice de la pompe. Cette première surface concave sphérique 241a coopère avec la partie de la surface convexe sphérique 211 de la rotule sphérique 210 du coté de sa grande base, au niveau du deuxième plan de section 222. La partie restante de la surface convexe sphérique 211 de la rotule sphérique 210 coopère en glissement et en appui avec une deuxième surface interne concave sphérique 241b d'une deuxième partie 240b de pièce d'appui qui vient en continuité de la première surface concave sphérique lorsque la deuxième partie 240b de pièce d'appui est appliquée contre la première partie de pièce d'appui 240a. La deuxième partie de pièce d'appui se présente sous la forme d'une collerette, maintenue de manière étanche à l'aide d'un premier joint torique 244 contre ladite première partie de pièce d'appui 240a par un collier de serrage 250. Le collier de serrage 250 comprend un filetage interne apte à coopérer avec un filetage externe complémentaire sur le pourtour externe cylindrique de la partie supérieure de la première partie 240a de la pièce d'appui.
A spherical ball joint according to the invention 200a, 200b, is composed of:
  1. a- an internal spherical ball 210, having a convex outer surface, of spherical cross-section, 211, surmounted by a hollow tubular end-piece 230 coming in the prolongation of an internal cavity for fluid passage, delimited by a frustoconical surface of revolution. 220, here represented at right generator, said frustoconical cavity 220 having a first axis of revolution X 1 X ' 1 . Said frustoconical cavity has a small open base at a first section plane 221 and a large circular base open at a second section plane 222, the two section planes being perpendicular to the axis X 1 X ' 1 . It will be understood that these two section planes 221 and 222 delimit the spherical section of said spherical ball joint 210. Said spherical ball joint comprises at its end, on the side of said small circular open base at the level of the first section plane 221, a cylindrical tubular endpiece. 230, whose second axis of revolution X 2 X ' 2 is inclined at an angle α 2 with respect to said first axis of revolution X 1 X' 1 of said frustoconical internal cavity 220, the frustoconical internal cavity 220 extending through the cavity tubular internal member 213 of said cylindrical tubular nozzle. By the inclination α 2 between the two axes X 2 X ' 2 and X 1 X' 1 , the tubular internal cavity 231 has a beveled end at the small circular open base of the frustoconical internal cavity at the first section plane 221, and a second right end adapted to be fitted at the end of a water circulation pipe 10 1 , 10 2 .
  2. b- a support piece 240 in two parts 240a and 240b. This support piece comprises a concave inner surface of spherical section against which the outer convex surface 211 of spherical section of the spherical ball rotates in rotation. The first abutment 240a comprises a first internally perforated inner spherical concave surface 241a 243 adapted to fit at a tubular port end 1a, 1b of pump or directly on the pump port, said spherical concave bearing surface 241a-241b having the same axis of revolution XX 'as the orifice of the pump. This first spherical concave surface 241a cooperates with the portion of the spherical convex surface 211 of the spherical ball 210 on the side of its large base, at the level of the second section plane 222. The remaining portion of the spherical convex surface 211 of the spherical ball joint 210 co-operates in sliding and in abutment with a second spherical concave internal surface 241b of a second part 240b of bearing piece which comes in continuity with the first spherical concave surface when the second part 240b of the support part is applied against the first part of support piece 240a. The second bearing part is in the form of a collar, sealingly held by a first O-ring 244 against said first bearing part 240a by a clamp 250. The clamping collar 250 comprises an internal thread adapted to cooperate with a complementary external thread on the cylindrical outer periphery of the upper part of the first part 240a of the support piece.

Tel que représenté sur les figures 6 et 7, l'étanchéité du raccord 200a, 200b, au niveau de la jonction entre lesdites première partie 240a et deuxième partie 240b de pièces d'appuis, est complétée par deux autres joints toriques 245 et 246. Le deuxième joint torique 245 est intercalé entre la première surface concave sphérique 241a et la surface convexe sphérique 211. Le troisième joint torique 246 est intercalé entre la première surface concave sphérique 241a de ladite première partie de pièce d'appui et la surface convexe sphérique 211 de la rotule sphérique. Lesdits deuxième joint torique 245 et troisième joint torique 246 sont situés, respectivement, à proximité de l'extrémité desdites deuxième et première surfaces concaves sphériques 241b et 241a, de part et d'autre et à proximité dudit premier joint torique 244. A l'autre extrémité 248 de la deuxième surface concave sphérique 241b, on a placé un quatrième joint torique 247 qui, lui aussi, assure l'étanchéité entre la surface convexe sphérique 211 et la deuxième surface concave sphérique 241b.As shown on the figures 6 and 7 , the sealing of the connection 200a, 200b, at the junction between said first portion 240a and second portion 240b of support members, is completed by two other O-rings 245 and 246. The second O-ring 245 is interposed between the first spherical concave surface 241a and the spherical convex surface 211. The third O-ring 246 is interposed between the first spherical concave surface 241a of said first support part. and the convex spherical surface 211 of the spherical ball. Said second O-ring 245 and third O-ring 246 are located, respectively, near the end of said second and first spherical concave surfaces 241b and 241a, on either side and in proximity to said first O-ring 244. At the another end 248 of the second spherical concave surface 241b, a fourth O-ring 247 is placed which also seals between the convex spherical surface 211 and the second spherical concave surface 241b.

Le raccord à rotule sphérique 200a, qui coopère avec l'orifice d'aspiration 1a, a une première partie 240a de pièce d'appui qui présente en sous-face des nervures ou arêtes de renfort 242 qui viennent en appui contre la surface supérieure du capot 1c, autour de l'orifice d'aspiration 1a, compte tenu du fait que le courant d'eau a tendance à écraser la pièce d'appui contre ledit capot de par le sens de circulation d'eau de l'extérieur vers l'intérieur de la pompe à ce niveau-là.The spherical ball joint 200a, which cooperates with the suction orifice 1a, has a first part 240a of support piece which has on the underside ribs or reinforcing edges 242 that bear against the upper surface of the 1c cover, around the suction port 1a, given that the water flow tends to crush the support piece against said hood in the direction of water flow from the outside to the inside the pump at this level.

La surface tronconique de la cavité tronconique 220 présente une inclinaison α3 d'environ 25° par rapport audit premier axe de révolution X1X'1 de ladite cavité tronconique 220. Lorsque la rotule sphérique est telle que son dit premier axe de révolution X1X'1 est dans l'alignement de l'axe XX' de l'orifice de la pompe et de l'orifice central 243 de ladite première surface concave sphérique 240a, la jonction entre lesdites première et deuxième surfaces concaves sphériques 240a et 240b et ledit premier joint torique 244 correspond sensiblement à l'équateur de la surface concave sphérique 211.The frustoconical surface of the frustoconical cavity 220 has an inclination α 3 of about 25 ° relative to said first axis of revolution X 1 X ' 1 of said frustoconical cavity 220. When the spherical ball is such that its said first axis of revolution X 1 X ' 1 is in alignment with the axis XX' of the pump orifice and the central orifice 243 of said first spherical concave surface 240a, the junction between said first and second spherical concave surfaces 240a and 240b and said first O-ring 244 substantially corresponds to the equator of the spherical concave surface 211.

Le deuxième axe de révolution X2X'2 de l'embout cylindrique 230 est incliné d'un angle α2 de 13°par rapport audit premier axe de révolution X1X'1 de la cavité interne tronconique 220 de la rotule 210. La rotule 210 peut pivoter d'un angle α1 par rapport à l'axe XX' dudit orifice central 243 ou de l'orifice 1a, 1b de la pompe, inférieur ou égal à α1max de 17°.The second axis of revolution X 2 X ' 2 of the cylindrical nozzle 230 is inclined at an angle α 2 of 13 ° with respect to said first axis of revolution X 1 X' 1 of the frustoconical internal cavity 220 of the ball 210. The ball 210 can pivot by an angle α 1 with respect to the axis XX 'of said central orifice 243 or the orifice 1a, 1b of the pump, less than or equal to α 1 max of 17 °.

Sur les figures 6 et 7, on a représenté les deux positions de rotation maximale opposées de la rotule sphérique.On the figures 6 and 7 the two opposite maximum rotation positions of the spherical ball are shown.

Sur la figure 6, la rotule sphérique est en position de rotation minimale, son premier axe de révolution X1X'1 étant incliné d'un angle - (α1max - α2) par rapport à l'axe XX' de l'orifice 1b, 1b de la pompe et de l'orifice central 243 de ladite pièce d'appui 240. Dans cette position la base 213 de l'extrémité biseautée de l'embout cylindrique 230, au niveau de la rencontre de son grand coté avec la surface concave sphérique 211, vient buter contre l'extrémité 248 de la deuxième partie 240b de la pièce d'appui, sensiblement au niveau du quatrième joint torique 247.On the figure 6 the spherical ball is in the minimum rotational position, its first axis of revolution X 1 X ' 1 being inclined by an angle - (α 1 max - α 2 ) with respect to the axis XX' of the orifice 1b, 1b of the pump and the central orifice 243 of said support piece 240. In this position the base 213 of the beveled end of the cylindrical end piece 230, at the level of the meeting of its large side with the concave surface spherical 211, abuts against the end 248 of the second portion 240b of the support piece, substantially at the fourth O-ring 247.

De la même manière, dans l'autre position maximale d'inclinaison de la figure 7, dans laquelle ledit deuxième axe de révolution X2X'2 de l'embout cylindrique 230 est incliné d'un angle maximal α1max + α2 par rapport à l'axe XX' de l'orifice central 243 et orifice 1a, 1b de la pompe, c'est la base 212 du petit coté de l'extrémité biseauté de l'embout cylindrique 230, au niveau de la jonction avec la surface convexe sphérique 211 qui vient buter contre l'extrémité 248 de ladite deuxième partie 240b de la pièce d'appui.In the same way, in the other maximum position of inclination of the figure 7 in which said second axis of revolution X 2 X ' 2 of the cylindrical nozzle 230 is inclined at a maximum angle α 1 max + α 2 with respect to the axis XX' of the central orifice 243 and orifice 1a, 1b of the pump, it is the base 212 of the short side of the bevelled end of the cylindrical nozzle 230, at the junction with the convex spherical surface 211 which abuts against the end 248 of said second portion 240b of the support piece.

Dans les deux positions des figures 6 et 7, on voit que l'autre extrémité 214 de la surface convexe sphérique 211, qui délimite la grande base circulaire ouverte de la cavité tronconique 220 au niveau dudit premier plan de section 221, n'empiète pas sur ledit orifice central 243, de façon à ne pas affecter l'hydraulicité de la pompe, et du coté diamétralement opposé, l'extrémité 214 de ladite surface convexe 211 reste en deçà dudit troisième joint torique 246, de façon à préserver une étanchéité optimale audit raccord à rotule sphérique.In both positions figures 6 and 7 it can be seen that the other end 214 of the convex spherical surface 211, which delimits the large open circular base of the frustoconical cavity 220 at said first section plane 221, does not impinge on said central orifice 243, so as to do not affect the hydraulicity of the pump, and the diametrically opposite side, the end 214 of said convex surface 211 remains below said third O-ring 246, so as to maintain an optimum seal to said spherical ball joint.

On comprend que la surface convexe sphérique 211 délimitée entre les deux plans de section 221 et 222 doit être suffisamment longue dans la direction de l'axe X1X'1 pour que ladite surface convexe sphérique reste toujours en appui sur une lesdites première et deuxième surfaces concaves sphériques d'appui, mais pas trop longue pour que l'extrémité 214 de ladite surface convexe sphérique 211 n'empiète pas sur l'orifice central 243, le choix des valeurs des angles α2 et α1max mentionnés ci-dessus permet de concilier ces deux exigences.It is understood that the convex spherical surface 211 delimited between the two section planes 221 and 222 must be sufficiently long in the direction of the axis X 1 X ' 1 so that said spherical convex surface always remains supported on a said first and second concave spherical bearing surfaces, but not too long for the end 214 of said spherical convex surface 211 n does not encroach on the central orifice 243, the choice of the values of the angles α 2 and α 1 max mentioned above makes it possible to reconcile these two requirements.

Dans toutes les directions de rotation d'un plan passant par ledit deuxième axe de révolution X2X'2 et dit axe XX' de l'orifice central 243, rotation sur 360° par rapport audit axe XX' de l'orifice 243, ledit deuxième axe X2X'2 peut être incliné d'une valeur de -αmax à +αmax, avec αmax = α2+α1max. Mais, dans une direction donnée, en l'absence de rotation par rapport à l'axe XX', c'est-à-dire dans un plan fixe donné passant par lesdits premier et deuxième axes X1X'1 et X2X'2 et l'axe XX' de l'orifice central 243, l'axe X2X'2 peut pivoter par rapport à un axe perpendiculaire à XX' et être incliné par rapport à l'axe XX' de l'orifice central 243 d'une valeur de - |α1 max-α2| à (α1 max+α2). Entre ces deux extrêmes, l'axe de pivotement de l'embout cylindrique X2X'2 par rapport à l'axe XX' passe par une valeur de α = 0, correspondant à une position dans laquelle ledit deuxième axe de révolution X2X'2 de l'embout cylindrique est parallèle à l'axe XX' de l'orifice central 243, dans la mesure où l'inclinaison de l'embout cylindrique par rapport à l'axe X1X'1 de la cavité tronconique de la rotule 210 crée un déport latéralement de l'axe de l'embout cylindrique X2X'2 par rapport à l'axe XX' de l'orifice central 243.In all directions of rotation of a plane passing through said second axis of revolution X 2 X ' 2 and said axis XX' of the central orifice 243, rotation over 360 ° with respect to said axis XX 'of the orifice 243, said second axis X 2 X ' 2 can be inclined from a value of -αmax to + αmax, with αmax = α 2 + α 1 max. But, in a given direction, in the absence of rotation relative to the axis XX ', that is to say in a given fixed plane passing through said first and second axes X 1 X' 1 and X 2 X 2 and the axis XX 'of the central orifice 243, the axis X 2 X' 2 can pivot relative to an axis perpendicular to XX 'and be inclined with respect to the axis XX' of the central orifice 243 of a value of - | α 1 max-α 2 | at (α 1 max + α 2 ). Between these two extremes, the axis of pivoting of the cylindrical tip X 2 X ' 2 with respect to the axis XX' passes through a value of α = 0, corresponding to a position in which said second axis of revolution X 2 X ' 2 of the cylindrical nozzle is parallel to the axis XX' of the central orifice 243, insofar as the inclination of the cylindrical nozzle relative to the axis X 1 X ' 1 of the frustoconical cavity of the ball 210 creates an offset laterally of the axis of the cylindrical tip X 2 X ' 2 with respect to the axis XX' of the central orifice 243.

Le diamètre D2 de la cavité interne tubulaire 231 de l'embout cylindrique 230 est légèrement supérieur au diamètre D1 de l'orifice central 243 car les extrémités des tuyaux 101, 102, de même diamètre D1 que l'orifice central 243 ou diamètre de l'orifice de la pompe, viennent s'emmancher à l'intérieur de l'embout cylindrique 230.The diameter D2 of the tubular internal cavity 231 of the cylindrical nozzle 230 is slightly greater than the diameter D1 of the central orifice 243 because the ends of the pipes 10 1 , 10 2 , of the same diameter D1 as the central orifice 243 or diameter of the pump orifice, come to get inside the cylindrical nozzle 230.

  • diamètre de la grande base circulaire ouverte de la rotule sphérique ou distance entre ses deux extrémités 214, L = 96 mm.

The turbine casing body 10b is mounted in attachment with the electric motor 10a.

Le corps de pré filtre est en dépression relative lorsque la pompe fonctionne, 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 de type panier, avant d'arriver dans le corps d'enveloppe de la turbine pour être refoulé par ledit orifice de refoulement en direction du filtre à sable ou autre accessoire de traitement de l'eau. On peut notamment mettre en oeuvre des raccords à rotule sphérique selon l'invention dans une pompe telle que décrite dans la demande de brevet en France n° 07 59635 .However, as previously mentioned, the couplings according to the present invention can be applied to hydraulic pumps for swimming pools, more particularly to a pump comprising a body of hydraulic part adapted to cooperate with a body of electric pump motor, said body of hydraulic part. including a pre-filter body comprising a suction port adapted to cooperate with a rigid pipe for the supply of water from a pool, said pre-filter body comprising or being able to cooperate with a turbine casing body comprising a discharge orifice whose cover 1c comprises a tangential discharge orifice adapted to discharge water in a pipe towards the pool, preferably via a filter to sand or other water treatment accessory for example, when said turbine is rotated by an electric motor cooperating with said casing body. The pre-filter body is in relative depression when the pump is running, the water arrives in the pre-filter body via said suction orifice, passes through a filtration system inside the pre-filter body, in particular basket type, before arriving in the casing body of the turbine to be discharged by said discharge port towards the sand filter or other water treatment accessory. Spherical ball joints according to the invention may in particular be used in a pump as described in French patent application no. 07 59635 .
