Abstract

The device consists of a cylinder (1) fitted with input and output apertures for the fuel. A float (2) moves vertically inside this cylinder (1). This float (2) is fitted with an electrically conductive component which slides along a resistor, thus forming a variable resistance which is a function of the level of fuel. The resistor is formed by two small plates (7) which are formed of metallic, or plastics material. The plates have a printed resistor on one face. These two small plates (7) are fixed back to back with the resistors on the outside. The conductive component (8) fixed onto the float (2) comprises two supple strips (9) connected together at one end, the other ends of which slide along the resistive plates (7).

A l'intérieur de ce corps se déplace verticalement un flotteur. Toujours à l'intérieur du corps cylindrique est disposée une résistance electrique sur laquelle coulisse un élément conducteur qui fait partie de cette résistance pour constituer une résistance variable en fonction du niveau du combustible. Le corps cylindrique creux est fermé à sa partie inférieure par un bouchon muni d'un filtre de combustible et, à sa partie superieure par une tête ou bloc superieur.Le corps est traversé par un tuyau d'aspiration de combustible qui traverse également le bouchon inférieur et la tête supérieure. The present application relates to a device emitting an electrical signal of liquid level in fuel tanks, applicable in particular to flat tanks of vehicles, of the type of those comprising a hollow cylindrical body, provided with small inlet and outlet openings. of the fuel they contain. Inside this body moves a float vertically. Also inside the cylindrical body is disposed an electrical resistance on which slides a conductive element which is part of this resistance to constitute a variable resistance according to the level of the fuel. The hollow cylindrical body is closed at its lower part by a cap fitted with a fuel filter and, at its upper part by a head or upper block. The body is crossed by a fuel suction pipe which also passes through the cap lower and upper head.

Dans son essence, le dispositif dont il est ici question est caractérise par le fait que ladite résistance est constitué par deux réglettes planes en matière plastique ou métallique, portant chacune, imprimée sur une face, une résistance électrique et étant adossées entre elles par leur face non munie de cette résistance, de telle sorte qu'elles sont reliées par un élement conducteur constitué de deux tiges ou lames souples disposes sur le flotteur, reliées elles-mêmes par l'une de leurs extrémités et mises en contact coulissant par l'autre extrémité avec la résistance électrique imprimée sur la reglette correspondante. In its essence, the device in question here is characterized by the fact that said resistance consists of two flat strips of plastic or metallic material, each carrying, printed on one side, an electrical resistance and being leaned together by their face not provided with this resistor, so that they are connected by a conductive element consisting of two flexible rods or blades arranged on the float, themselves connected by one of their ends and brought into sliding contact by the other end with the electrical resistance printed on the corresponding slide.

D'autres caractéristiques et avantages du dispositif émetteur objet de la présente demande vont se dégager de la description suivante qui correspond aux dessins ci-joints, servant d'illustration d'un mode de réalisation de ce dispositif, à titre d'exemple non limitatif. Other characteristics and advantages of the emitting device which is the subject of this application will emerge from the following description which corresponds to the attached drawings, serving to illustrate an embodiment of this device, by way of non-limiting example .

La figure i est une vue en projection, avec coupe, du dispositif émetteur dont il est question. Figure i is a projected view, in section, of the transmitter device in question.

La figure 2 montre une coupe transversale selon II-II de la figure 1. Figure 2 shows a cross section along II-II of Figure 1.

La figure 3 est une vue de dessus du dispositif représenté sur la figure 1. Figure 3 is a top view of the device shown in Figure 1.

Ces dessins permettent de voir que le dispositif émetteur dont il est ici question, comporte un corps cylindrique creux à l'intérieur duquel se déplace dans le plan vertical, un flotteur qui surnage à la surface du combustible. These drawings show that the emitting device in question here comprises a hollow cylindrical body inside which moves in the vertical plane, a float which floats on the surface of the fuel.

Ce corps cylindrique creux 1 est fermé par deux bouchons, un bouchon inférieur 3 muni d'un filtre de combustible 4 et, un bouchon supérieur 5. Ce corps 1 est traversé par un tuyau 6 d'aspiration du combustible, qui traverse également le bouchon inférieur 3 et le bouchon supérieur 5. This hollow cylindrical body 1 is closed by two plugs, a lower plug 3 provided with a fuel filter 4 and, an upper plug 5. This body 1 is crossed by a fuel suction pipe 6, which also passes through the plug lower 3 and the upper plug 5.

A l'intérieur du corps cylindrique creux 1 est placée une résistance électrique constituée par deux réglettes plates 7 en matière plastique ou métallique, portant chacune sur l'une des faces une résistance électrique. Les deux réglettes sont dos à dos par leur face non munie de résistance, de telle sorte qu'elles sont mises en contact entre elles par un élément conducteur 8 qui participe avec la résistance électrique à la formation d'une résistance variable en fonction du niveau de combustible. Inside the hollow cylindrical body 1 is placed an electrical resistance constituted by two flat strips 7 of plastic or metallic material, each carrying on one of the faces an electrical resistance. The two strips are back to back by their side not provided with a resistance, so that they are brought into contact with each other by a conductive element 8 which participates with the electrical resistance in the formation of a variable resistance depending on the level of fuel.

En outre, chaque réglette porte, imprimée, une piste conductrice prévue pour refermer le circuit d'une lampe témoin de la réserve de combustible contenue dans le réservoir, grâce au même élément conducteur 8.In addition, each strip carries, printed, a conductive track provided for closing the circuit of a lamp indicating the fuel reserve contained in the tank, thanks to the same conductive element 8.

Cet élément conducteur 8 est constitué par deux tiges ou lames souples 9, assemblées solidairement sur le flotteur 2, reliées entre elles par l'une de leurs extrémités à l'aide de la plaquette 10 et mises de façon coulissante par l'autre extrémité, en contact avec la résistance électrique respective de l'une des réglettes 7. This conductive element 8 is constituted by two flexible rods or blades 9, assembled integrally on the float 2, connected to one another by one of their ends using the plate 10 and slidably put by the other end, in contact with the respective electrical resistance of one of the strips 7.

Le bouchon supérieur 5 est moulé en une seule pièce de matière plastique et est muni des contacts électriques Il pour la transmission du signal ohmique à l'aiguille d'un indicateur, de même que d'un passage 12 pour le tuyau 6 d'aspiration du combustible, d'un tuyau 13 de retour de combustible en excès provenant du carburateur, d'un tuyau d'aération 14 et d'un tuyau de refoulement 15 permettant d'éviter la formation de mousse à la surface du combustible. The upper plug 5 is molded in a single piece of plastic and is provided with electrical contacts II for the transmission of the ohmic signal to the needle of an indicator, as well as a passage 12 for the suction pipe 6 fuel, a pipe 13 for return of excess fuel coming from the carburetor, a ventilation pipe 14 and a discharge pipe 15 making it possible to prevent foaming on the surface of the fuel.

La paroi du corps cylindrique creux 1 est constituée d'une feuille, en matière plastique ou métallique, enroulée sur elle-même. The wall of the hollow cylindrical body 1 consists of a sheet, of plastic or metallic material, wound on itself.

I1 est précisé que tout ce qui n'altère, ne change ou ne modifie pas l'essentiel du dispositif émetteur du signal électrique de niveau de liquide dans les réservoirs de combustible décrit, peut subir des aménagements de détail.  I1 is specified that anything which does not alter, does not change or does not modify the essentials of the device emitting the electrical signal of liquid level in the fuel tanks described, can undergo detailed arrangements.
