La présente invention a pour objet un dispositif d'alimentation en carburant monté dans le réservoir d'un véhicule. The present invention relates to a fuel supply device mounted in the tank of a vehicle.
Le brevet principal concerne un dispositif d'alimentation en carburant monté dans le réservoir d'un véhicule, comportant une enceinte reposant sur le fond du réservoir et qui est en communication à sa base par des orifices avec l'intérieur du réservoir, ladite enceinte qui est munie d'une aspiration de carburant étant prolongée à sa partie supérieure par une cheminée qui comporte à sa partie supérieure une platine fixée sur le réservoir et sur laquelle sont fixées une tubulure d'évent en communication à l'une de ses extrémités avec l'intérieur du réservoir et dont ;'autre extrémité est reliée à ltatmosphère par un conduit une tubulure d'aspiration de carburant et une tubulure de retour de carburant. The main patent relates to a fuel supply device mounted in the tank of a vehicle, comprising an enclosure resting on the bottom of the tank and which is in communication at its base by orifices with the interior of the tank, said enclosure which is provided with a fuel suction being extended at its upper part by a chimney which comprises at its upper part a plate fixed on the tank and on which are fixed a vent pipe in communication at one of its ends with the 'interior of the tank and whose;' other end is connected to the atmosphere by a conduit a fuel suction pipe and a fuel return pipe.
Toutefois, lorsque ce dispositif est utilisé avec certains types de réservoirs et notamment des réservoirs en matière plastique, le problème de la hauteur de puisage se pose avec une plus grande acuité qu'avec les réservoirs métalliques, car elle est impossible à maitriser, si les trois paramètres suivants viennent modifier en permanence cette hauteur
. la cotede fabrication, à tolérance large pour tenir compte des impératifs du soufflage,
la déformation au vieillissement due au matériau employé qui n'est pas stabilisé dans le temps,
la déformation au chargement due à la poussée du liquide sur le fond du réservoir.However, when this device is used with certain types of tanks and in particular plastic tanks, the problem of the drawing height arises with greater acuity than with metal tanks, because it is impossible to control, if the the following three parameters permanently modify this height
. the manufacturing cost, with wide tolerance to take into account the requirements of blowing,
deformation due to aging due to the material used which is not stabilized over time,
loading deformation due to the thrust of the liquid on the bottom of the tank.
Conformément à la présente addition, l'enceinte est maintenue plaquée contre le fond du réservoir par un moyen de rattrapage de hauteur disposé entre la cheminée et ladite enceinte. In accordance with this addition, the enclosure is held pressed against the bottom of the tank by a height adjustment means disposed between the chimney and said enclosure.
Cette disposition permet de maintenir l'enceinte plaquée sur le fond du réservoir quelle que soit la hauteur de celui-ci. This arrangement makes it possible to maintain the enclosure pressed against the bottom of the tank whatever the height thereof.
Suivant une autre caractéristique de l'invention, l'enceinte repose sur le fond du réservoir avec interposition d'une semelle de compensation des vibrations. According to another characteristic of the invention, the enclosure rests on the bottom of the tank with the interposition of a vibration compensation sole.

Aux figures 1 et 2, on a représenté le dispositif d'alimentation en carburant suivant l'invention dans lequel l'enceinte 2 repose sur le fond la du réservoir avec interposition d'une semelle 31 de compensation pour absorber les vibrations. In Figures 1 and 2, there is shown the fuel supply device according to the invention in which the enclosure 2 rests on the bottom of the tank with the interposition of a compensation sole 31 to absorb vibrations.
L'enceinte 2 est munie à sa partie supérieure d'une tige 32 qui est montée coulissante dans un alésage 33 d'un manchon 34 solidaire de la cheminée 7 qui s'étend jusqu'8 la paroi supérieure du réservoir 1 ainsi qu'il a été décrit dans le brevet principal. The enclosure 2 is provided at its upper part with a rod 32 which is slidably mounted in a bore 33 of a sleeve 34 integral with the chimney 7 which extends to the upper wall of the tank 1 as well as has been described in the main patent.
Entre la cheminée 7 et la partie supérieure de l'enceinte 2 est en appui un ressort 35 qui repousse l'enceinte 2 contre le fond la du réservoir et maintient celle-ci en appui contre ledit fond, la tige 32 étant susceptible de se déplacer d'une distance X. Between the chimney 7 and the upper part of the enclosure 2 is in support a spring 35 which pushes the enclosure 2 against the bottom 1a of the tank and keeps the latter in abutment against said bottom, the rod 32 being capable of moving from a distance X.
L'enceinte 2 est reliée aux tubulures de sortie et d'entrée du carburant par des conduits d'aspiration 12 et de retour 13 qui sont munis sur une certaine partie de leur longueur de soufflets 36, 37 permettant de rattraper les différences de hauteur du réservoir. The enclosure 2 is connected to the fuel outlet and inlet pipes by suction 12 and return 13 pipes which are provided over a certain part of their length with bellows 36, 37 making it possible to make up for the differences in height of the tank.
Dans le mode de réalisation représenté aux figures 1, 2, 2a, le passage du conduit de retour 12 est contrôlé par un organe obturateur 38 susceptible de mettre en communication par la gorge 39 la partie 12a du conduit de retour avec la partie 12 du conduit aboutissant à l'enceinte 2 ou avec l'orifice de sortie 40 (figure 2a) débouchant directement dans le réservoir. L'organe obturateur 38 est actionné par une capsule thermostatique 41 en contact avec le fluide du conduit d'aspiration 13, ladite capsule agissant à l'encontre d'un ressort 42 en appui d'un côté contre l'organe obturateur et de l'autre côté contre le fond d'un logement 43 ménagé dans le puits 7. Cette disposition permet une régulation thermique qui module la température à l'entrée de la pompe et évite toute surchauffe du carburant. In the embodiment shown in FIGS. 1, 2, 2a, the passage of the return conduit 12 is controlled by a shutter member 38 capable of bringing the part 12a of the return conduit into communication with the groove 39 with the part 12 of the conduit ending at the enclosure 2 or with the outlet orifice 40 (FIG. 2a) opening directly into the tank. The shutter member 38 is actuated by a thermostatic capsule 41 in contact with the fluid of the suction duct 13, said capsule acting against a spring 42 bearing on one side against the shutter member and the 'other side against the bottom of a housing 43 formed in the well 7. This arrangement allows a thermal regulation which modulates the temperature at the inlet of the pump and prevents any overheating of the fuel.
A la figure 3, on a représenté une semelle 31a qui est disposée entre l'enceinte 2 et le fond la du réservoir et qui présente une forme ovale comme celle utilisée aux figures 1 et 2. In FIG. 3, a sole 31a has been shown which is disposed between the enclosure 2 and the bottom 1a of the tank and which has an oval shape like that used in FIGS. 1 and 2.
Aux figures 5 et 6, on a représenté un autre mode de réalisation d'une semelle circulaire 31b dont le bord 44 est effilé ainsi qu'il est représenté à la figure 4. In FIGS. 5 and 6, another embodiment of a circular sole 31b is shown, the edge 44 of which is tapered as shown in FIG. 4.
Aux figures 7 et 8, on a représenté un dispositif dans lequel le puits 7 est muni sur l'une de ses faces d'une jauge 45 mesurant le niveau du liquide dans le réservoir et qui est reliée électriquement de façon connue à un organe indicateur. In Figures 7 and 8, there is shown a device in which the well 7 is provided on one of its faces with a gauge 45 measuring the level of the liquid in the reservoir and which is electrically connected in a known manner to an indicator member .
La jauge 45 comporte un bras pivotant 46 qui est muni à l'une de ses extrémités d'un flotteur 47 qui suit les déplacements du liquide dans le réservoir.The gauge 45 comprises a pivoting arm 46 which is provided at one of its ends with a float 47 which follows the movements of the liquid in the tank.
A la figure 9, on a représenté une enceinte 2 dans laquelle est disposée une pompe d'alimentation 48 du type immergé et qui est fixée à la partie supérieure de l'enceinte 2. In FIG. 9, an enclosure 2 is shown in which a supply pump 48 of the submerged type is arranged and which is fixed to the upper part of the enclosure 2.
La pompe 48 comporte des conduits d'aspiration 12 et de refoulement 13 comme il a été décrit ci-dessous. The pump 48 includes suction 12 and discharge 13 ducts as described below.
A la figure 10, on a représenté un dispositif constituant l'une des partie d'une jauge électronique et qui comprend une enveloppe cylindrique 49 fixée à sa partie supérieure sur une platine 8 solidaire de la paroi supérieure du réservoir, ladite enveloppe étant disposée autour de 11 enceinte 2 et du puits 7. In Figure 10, there is shown a device constituting one of the parts of an electronic gauge and which comprises a cylindrical casing 49 fixed at its upper part on a plate 8 secured to the upper wall of the tank, said casing being arranged around of 11 enclosure 2 and well 7.
A sa base, l'enveloppe présente des orifices 3 comme l'enceinte 2. At its base, the envelope has orifices 3 like the enclosure 2.
Par ailleurs, à l'extérieur de l'enveloppe 49 est disposée une piste conductrice hélicoidale 50 qui est constituée de barres parallèles 51 espacées par des intervalles. Furthermore, outside the envelope 49 is arranged a helical conductive track 50 which consists of parallel bars 51 spaced apart by intervals.
Le bottier 21 qui est garni intérieurement d'une matiere isolante est muni d'un moyen de fixation inviolable. The shell 21 which is lined internally with an insulating material is provided with a tamper-proof fixing means.
A l'intérieur de l'enceinte 2 sont prévues des chicanes destinées à favoriser le dégazage. Inside the enclosure 2 are provided baffles intended to promote degassing.
Bien entendu, l'invention n'est pas limitative et l'homme de l'art pourra y apporter des modifications sans sortir pour cela du domaine de l'invention. Of course, the invention is not limiting and those skilled in the art may make modifications to it without departing from the scope of the invention.
