Description

DOMAINE TECHNIQUETECHNICAL AREA

La présente invention est relative au module de pompage de carburant d'un véhicule et plus particulièrement au limiteur de pression qui équipe un tel module.The present invention relates to the fuel pump module of a vehicle and more particularly to the pressure limiter which equips such a module.

ARRIERE-PLAN TECHNOLOGIQUE DE L'INVENTIONBACKGROUND OF THE INVENTION

Dans le réservoir à carburant d'un véhicule, une pompe aspire le carburant à pression atmosphérique et l'envoi comprimé vers le système d'injection du moteur du véhicule. La pompe est agencée dans un module de pompage. La sortie de la pompe est connectée à une canalisation haute pression et un régulateur de pression dont la version simple est un limiteur de pression normalement fermé. Sous l'effet d'une pression trop élevée dans la canalisation haute pression, le limiteur s'ouvre et permet à une partie du carburant de retourner vers le réservoir et, ainsi de maintenir le carburant dans le système d'injection sous une valeur limite de pression. Les limiteurs de pressions classiques ont un ressort taré qui maintient une bille contre un siège de vanne conique au centre duquel débouche un canal de retour vers le réservoir. Lorsque la pression du carburant dépasse la limite prédéterminée, le carburant repousse la bille qui comprime le ressort et une partie du carburant peut ainsi être évacué vers le réservoir. Les systèmes « start-stop » grâce auquel le moteur s'arrête complètement lorsque le véhicule est à l'arrêt et qui équipent les nouveaux véhicules diesel entrainent des variations de pressions beaucoup plus fréquentes et le limiteur doit s'ouvrir à chaque démarrage du moteur. Le simple limiteur à bille et ressort ne convient plus car mécaniquement trop instable. Effectivement, plutôt que de se déplacer linéairement selon l'axe de compression du ressort, le limiteur peut également subir des oscillations radiales, des mouvements de torsion du ressort ou tout autres combinaisons de qui perturbent le fonctionnement optimal et génèrent du bruit.In the fuel tank of a vehicle, a pump draws fuel at atmospheric pressure and sends it compressed to the vehicle engine injection system. The pump is arranged in a pumping module. The output of the pump is connected to a high pressure line and a pressure regulator whose simple version is a normally closed pressure limiter. Under the effect of too high pressure in the high pressure line, the limiter opens and allows some of the fuel to return to the tank and thus keep the fuel in the injection system under a limit value pressure. Conventional pressure limiters have a calibrated spring that holds a ball against a conical valve seat in the center of which opens a return channel to the reservoir. When the fuel pressure exceeds the predetermined limit, the fuel pushes the ball that compresses the spring and some of the fuel can be discharged to the tank. The "start-stop" systems by which the engine stops completely when the vehicle is stationary and which equips the new diesel vehicles cause much more frequent pressure variations and the limiter must open each time the engine is started. . The simple ball and spring limiter is no longer suitable because mechanically too unstable. Indeed, rather than linearly moving along the compression axis of the spring, the limiter can also undergo radial oscillations, torsional movements of the spring or any other combination of which interfere with the optimal operation and generate noise.

RESUME DE L'INVENTIONSUMMARY OF THE INVENTION

La présente invention vise à remédier aux inconvénients mentionnés précédemment en proposant une solution simple et économique.The present invention aims to remedy the disadvantages mentioned above by proposing a simple and economical solution.

Dans ce but, l'invention propose un module de pompage de carburant pour véhicule comprenant un corps, définissant un espace basse pression dans lequel est agencée une pompe à la sortie de laquelle est placé un limiteur de pression. Le limiteur de pression comprend un corps tubulaire s'étendant selon un axe principal entre une extrémité avant, où est agencé un siège de vanne au centre duquel débouche un canal de retour du carburant, et une extrémité arrière distante, le limiteur comprenant de plus un noyau pourvu d'un membre obturateur agencé coulissant dans le corps tubulaire entre une position fermée, dans laquelle sa face avant est en appui complémentaire contre le siège obturant le canal de retour et, une position ouverte dans laquelle sa face avant est éloignée du siège permettant l'évacuation d'une partie du carburant vers l'espace basse pression. Le noyau est de plus pourvu d'un membre élastique sollicitant en permanence le membre obturateur vers la position fermée. Ladite face avant du membre obturateur est une surface discale plane. Dans une alternative un joint en élastomère, un disque, ou un joint torique, peut être intercalé entre ladite face avant discale et le siège du limiteur.For this purpose, the invention provides a fuel pump module for a vehicle comprising a body defining a low pressure space in which is arranged a pump at the outlet of which is placed a pressure limiter. The pressure limiter comprises a tubular body extending along a main axis between a front end, which is arranged a valve seat in the center of which opens a fuel return channel, and a rear remote end, the limiter further comprising a core provided with a shutter member arranged sliding in the tubular body between a closed position, in which its front face is in complementary support against the seat closing the return channel and, an open position in which its front face is away from the seat allowing the evacuation of a portion of the fuel to the low pressure space. The core is further provided with an elastic member permanently urging the shutter member to the closed position. Said front face of the shutter member is a flat disc surface. Alternatively, an elastomeric seal, disc, or O-ring may be interposed between said disc front face and the limiter seat.

De plus l'élément élastique est un ressort hélicoïdal axialement comprimé entre la face arrière de l'élément obturateur, face opposée à ladite face avant, et l'extrémité arrière du corps tubulaire.In addition, the elastic element is a helical spring axially compressed between the rear face of the shutter element, face opposite said front face, and the rear end of the tubular body.

Dans une construction particulière le membre obturateur est fixé à une extrémité du ressort au moyen d'une protubérance pourvue sur sa face arrière et permettant un engagement complémentaire avec la dernière spire du ressort de sorte à fixer le membre obturateur au ressort. La protubérance peut être une paroi cylindre.In a particular construction the shutter member is attached to one end of the spring by means of a protuberance provided on its rear face and allowing complementary engagement with the last turn of the spring so as to fix the shutter member to the spring. The protuberance may be a cylinder wall.

De plus, le noyau peut comprendre un autre membre d'extrémité agencé à l'opposé du membre obturateur, entre l'extrémité arrière du corps et le ressort.In addition, the core may comprise another end member arranged opposite the obturator member, between the rear end of the body and the spring.

Il est particulièrement avantageux que le membre obturateur et ledit autre membre d'extrémité soient identiques et symétriquement agencés et maintenus aux extrémités opposées du ressort de sorte que le noyau formé par le ressort, le membre obturateur et ledit autre membre d'extrémité soit symétrique pouvant être agencé dans le corps tubulaire de sorte que l'un quelconque des deux membres coopère avec le siège.It is particularly advantageous that the obturator member and said other end member are identical and symmetrically arranged and held at opposite ends of the spring so that the core formed by the spring, the obturator member and said other end member is symmetrical which can to be arranged in the tubular body so that any one of the two members cooperates with the seat.

En outre, ladite extrémité arrière est pourvue d'une ouverture arrière par laquelle peut être inséré le noyau. Le limiteur est alors pourvu d'au moins un bras flexible, mais plus généralement une pluralité, s'étendant depuis le pourtour de l'ouverture arrière en direction de l'extrémité avant du corps jusqu'à une extrémité libre. Le bras s'écarte radialement lorsque le noyau est inséré et se rabat élastiquement derrière le noyau lorsque celui-ci est entièrement inséré de sorte que le noyau est maintenu en position fermée entre le membre obturateur en appui contre le siège et ledit autre membre d'extrémité contre lequel le bras est arc-bouté, le ressort étant comprimé.In addition, said rear end is provided with a rear opening through which the core can be inserted. The limiter is then provided with at least one flexible arm, but more generally a plurality, extending from the periphery of the rear opening towards the front end of the body to a free end. The arm moves radially away when the core is inserted and resiliently folds behind the core when fully inserted so that the core is held in a closed position between the shutter member resting against the seat and said other member. end against which the arm is braced, the spring being compressed.

Plus particulièrement le corps tubulaire est en plastique moulé venu de matière avec le corps du module.More particularly the tubular body is made of molded plastic material with the body of the module.

DESCRIPTION DES MODES DE REALISATION PREFERESDESCRIPTION OF THE PREFERRED EMBODIMENTS

Un module de pompage 10 de carburant C est représenté sur la figure 1. Il est prévu pour être agencé dans le réservoir d'un véhicule et baigner dans le carburant C. Le module comporte une électronique de commande placée dans un boitier étanche agencé au-dessus d'une partie basse comprenant un bol 12 en plastique moulé fermé par un couvercle 14 également en plastique moulé. L'intérieur du bol 12 définit un espace basse pression 16 dans lequel est agencée une pompe qui d'une part aspire le carburant C à la pression atmosphérique, la basse pression, pour l'envoyer en haute pression vers le système d'injection du moteur du véhicule. Dans le bas du module 10 représenté, un dispositif de niveau à balancier et flotteur est agencé permettant de déterminer la quantité de carburant C restant dans le réservoir.A fuel pumping module 10 is shown on the figure 1 . It is intended to be arranged in the tank of a vehicle and bathe in the fuel C. The module comprises a control electronics placed in a waterproof housing arranged above a lower part comprising a bowl 12 in molded plastic closed by a lid 14 also of molded plastic. The inside of the bowl 12 defines a low pressure space 16 in which is arranged a pump which on the one hand sucks the fuel C at atmospheric pressure, the low pressure, to send it at high pressure to the injection system of the vehicle engine. In the bottom of the module 10 shown, a rocker and float level device is arranged to determine the amount of fuel C remaining in the tank.

Le carburant C à haute pression quitte le bol 12 via une canalisation haute pression 18 qui traverse le couvercle 14. Des raccords tubulaires de la canalisation haute pression 18 sont venus de matière avec le couvercle 14.The high pressure fuel C leaves the bowl 12 via a high pressure line 18 which passes through the lid 14. The tubular connections of the high pressure line 18 are integral with the lid 14.

Le module 10 comprend de plus un limiteur de pression 20 agencé, dans l'exemple choisi pour illustrer cette description, dans l'épaisseur du couvercle 14. Le limiteur 20 comprend un corps tubulaire 22 s'étendant selon un axe principal A sensiblement perpendiculaire à la canalisation haute pression 18 entre une extrémité avant 24, où est agencé un siège 26 de vanne, et une extrémité arrière 28 distante de la canalisation haute pression 18. Le siège 26 est une surface complémentaire tel par exemple une surface torique ou une surface plane annulaire transversale à l'axe principal A. Une canalisation de retour 30 s'étend entre la canalisation haute pression 18 et la première extrémité 24 du corps 22 où elle débouche au centre du siège 26. Entre les deux extrémités 24, 28, le corps 22 est ajouré 32 tant vers l'intérieur que vers l'extérieur du bol 12. L'extrémité arrière 28 du corps 22 est pourvue d'une ouverture arrière 34 circulaire du pourtour de laquelle s'étendent, en direction de la première extrémité 24 et de manière légèrement centripète, des bras 36 allongés et flexibles. Tout en s'étendant, les bras 36 se rapprochent légèrement de l'axe principal A. Ils sont pourvus à leur extrémité libre de terminaisons 38 formant de manière imagée, une main à angle quasiment droit avec le bras tendu, la paume étant orientée vers l'avant. Tel que visible sur les figures 3 et 4, le corps 22 et les bras 36 sont en plastique moulé venus de matière avec le couvercle 14.The module 10 further comprises a pressure limiter 20 arranged, in the example chosen to illustrate this description, in the thickness of the lid 14. The limiter 20 comprises a tubular body 22 extending along a main axis A substantially perpendicular to the high pressure line 18 between a front end 24, which is arranged a valve seat 26, and a rear end 28 remote from the high pressure line 18. The seat 26 is a complementary surface such for example a toric surface or a flat surface annular transverse to the main axis A. A return pipe 30 extends between the high pressure pipe 18 and the first end 24 of the body 22 where it opens at the center of the seat 26. Between the two ends 24, 28, the body 22 is perforated 32 inwards and outwards of the bowl 12. The rear end 28 of the body 22 is provided with a circular rear opening 34 around which extend towards the first end 24 and in a slightly centripetal manner, elongate and flexible arms 36. While extending, the arms 36 are slightly closer to the main axis A. They are provided at their free end endings 38 forming an imaged manner, a hand at almost right angle with the arm extended, the palm being oriented towards forward. As visible on the Figures 3 and 4 , the body 22 and the arms 36 are molded plastic integrally with the lid 14.

Le limiteur 20 comprend également un noyau mobile telle que détaillé sur la figure 2. Le noyau comprend un ressort 40 hélicoïdal de compression muni à chacune de ses extrémité d'un embout 42. Les embouts 42 sont strictement identiques et à ce titre repérés par la même référence 42. Ils sont en plastique moulé, ils ont une face discale 44 plane pourvue d'un côté d'une portion cylindrique 46 d'axe perpendiculaire à la face discale 44. La portion cylindrique 46 a sensiblement le diamètre intérieur du ressort 40 de sorte que chaque embout 42 peut être maintenu à une extrémité du ressort 40 en insérant sa portion cylindrique 46 dans la dernière spire du ressort 40. L'assemblage du ressort 40 et des deux embouts 42 forme un noyau parfaitement symétrique 48. De nombreuses alternatives peuvent facilement être développées quant au mode de fixation des embouts et du ressort. Par exemple, plutôt que de s'insérer dans le ressort, la partie cylindrique pourrait être plus large de sorte à recevoir le ressort. De plus, le choix de réaliser un ensemble symétrique a des avantages qui seront explicités plus avant mais, rien n'empêche d'équiper le ressort d'embouts différents, voire d'un seul embout. Pour parfaire l'étanchéité, si cela était jugé nécessaire, il est possible d'intercaler un joint en élastomère entre le siège 26 et l'embout 42. Le joint peut par exemple être un joint plat ou bien un joint torique.The limiter 20 also comprises a mobile core as detailed on the figure 2 . The core comprises a helical compression spring 40 provided at each end thereof with a tip 42. The end pieces 42 are strictly identical and, as such, marked with the same reference numeral 42. They are made of plastic molded, they have a flat disc face 44 provided on one side with a cylindrical portion 46 of axis perpendicular to the disc face 44. The cylindrical portion 46 has substantially the inner diameter of the spring 40 so that each endpiece 42 can be maintained at one end of the spring 40 by inserting its cylindrical portion 46 in the last turn of the spring 40. The assembly of the spring 40 and the two ends 42 forms a perfectly symmetrical core 48. Many alternatives can easily be developed as to the mode of attachment of the ends and the spring. For example, rather than inserting into the spring, the cylindrical portion could be wider to receive the spring. In addition, the choice to achieve a symmetrical assembly has advantages that will be explained further, but nothing prevents to equip the spring of different tips, even a single tip. To perfect the seal, if it were deemed necessary, it is possible to insert an elastomeric seal between the seat 26 and the nozzle 42. The seal may for example be a flat seal or an O-ring.

Selon la figure 5 le noyau symétrique 48 est mis en place dans le corps 22 après l'avoir inséré axialement A au travers de l'ouverture arrière 34. Au cours de cette opération les bras 36 se sont légèrement déformés en s'écartant pour laisser passer le noyau 48. Celui-ci est inséré jusqu'à ce que l'embout 42 situé à l'avant arrive en contact complémentaire avec le siège 26 et soit alors bloqué. On comprendra alors que l'embout avant 42 soit un membre obturateur du canal de retour 30. On poursuit l'insertion en comprimant le ressort 40 jusqu'à ce que l'embout 42 situé à l'arrière ait dépassé les extrémités libres des bras 36 et qu'alors les bras 36 reprennent élastiquement leur forme libre et que les terminaisons 38 se placent contre la face discale 44 de l'embout arrière 42. On comprendra ici que les terminaisons 38, ci-avant les « mains », offrent un appui stable contre la face arrière 44 et dans ce but puissent être réalisées selon diverses formes tel le coin, le T ou autre. Par ailleurs, le grand intérêt de réaliser un noyau symétrique 48 apparait immédiatement puisque celui-ci peut être inséré indifféremment dans le corps 22 sans que soit nécessaire un quelconque repérage ou système détrompeur.According to figure 5 the symmetrical core 48 is placed in the body 22 after having inserted axially A through the rear opening 34. During this operation the arms 36 have slightly deformed by moving apart to let the core 48 This is inserted until the tip 42 located at the front comes into complementary contact with the seat 26 and is then blocked. It will be understood that the front end 42 is a shutter member of the return channel 30. The insertion is continued by compressing the spring 40 until the tip 42 located at the rear has passed the free ends of the arms 36 and that the arms 36 elastically resume their free form and that the endings 38 are placed against the disc face 44 of the rear end 42. It will be understood here that the endings 38, here before the "hands", provide a stable support against the rear face 44 and for this purpose can be made in various forms such as the corner, the T or other. Moreover, the great advantage of producing a symmetrical core 48 appears immediately since it can be inserted indifferently into the body 22 without the need for any identification or keying system.

Ainsi mis en place dans le corps 22, le ressort 40 est comprimé entre la face discale 44 avant qui est complémentairement appuyée contre le siège 26 et qui obture ainsi le canal de retour 30, et la face discale 44 arrière contre laquelle les bras 36 sont arc-boutés.Thus placed in the body 22, the spring 40 is compressed between the disc face 44 which is further pressed against the seat 26 and which thus closes the return channel 30, and the rear disc face 44 against which the arms 36 are braced.

La compression du ressort 40 créée une force d'appui F1 de l'embout 42 avant contre le siège 26. Lorsque le carburant C circule dans la canalisation haute pression 18 il exerce sur l'embout 42 avant une force F2 s'opposant à celle du ressort 4. Tant que la force F2 exercée par le carburant C est inférieure à celle exercée par le ressort 40, tel que selon la figure 6, le limiteur 20 est maintenu en position fermée PF. Lorsque la pression du carburant C augmente au-delà d'une limite L choisie, la force F2 qu'il exerce sur l'embout avant 42 vain la force F1 exercée par le ressort 40 de sorte que le ressort 40 se comprime et que l'embout avant 42 est repoussé tel que selon la figure 7 et s'éloigne du siège 26. Le limiteur 20 est alors en position ouvert PO et, du carburant C sous pression peut alors s'échapper en s'écoulant par le canal de retour 30 et revenir dans l'espace basse pression 16 en passant par les ajours 32 du corps 22 du limiteur 20.The compression of the spring 40 creates a bearing force F1 of the tip 42 before the seat 26. When the fuel C flows in the high pressure line 18 it exerts on the tip 42 before a force F2 opposing that 4. As long as the force F2 exerted by the fuel C is lower than that exerted by the spring 40, such as according to the figure 6 the limiter 20 is held in the closed position PF. When the pressure of the fuel C increases beyond a limit L chosen, the force F2 that it exerts on the front end 42 vain F1 force exerted by the spring 40 so that the spring 40 is compressed and that the front end 42 is pushed back as according to the figure 7 and move away from the seat 26. The limiter 20 is then in the open position PO and fuel C under pressure can then escape by flowing through the return channel 30 and back into the low pressure space 16 by passing through the openings 32 of the body 22 of the limiter 20.
