Description
f - 1 - L'invention concerne un dispositif de chauffage applicable à un filtre à carburant.f - 1 - The invention relates to a heating device applicable to a fuel filter.
Il est bien connu que le carburant utilisé pour les moteurs Diesel contient aussi de petites quantités de 5 paraffine. Cette substance a l'inconvénient de se solidifier à de basses températures, en particulier à des températures inférieures à 0°C de sorte qu'elle augmente l'obstruction aussi bien des conduits à carburant que des filtres principal ou secondaire prévus dans tout système d'alimen-10 tation de moteur Diesel.It is well known that the fuel used for diesel engines also contains small amounts of paraffin. This substance has the disadvantage of solidifying at low temperatures, in particular at temperatures below 0 ° C so that it increases the obstruction both of the fuel lines and of the main or secondary filters provided in any system. Diesel engine power supply.
* Un but de l'invention est de fournir un dispositif qui permette d'éviter cet inconvénient de façon simple et peu coûteuse.* An object of the invention is to provide a device which makes it possible to avoid this drawback in a simple and inexpensive manner.
L'invention propose un dispositif de chauffage conçu 15 pour être utilisé avec un filtre à carburant et caractérisé * par le fait qu'il comprend au moins une résistance électrique malléable et une bande malléable enroulée autour de la résistance et conçue pour être enroulée autour du filtre.The invention provides a heating device designed to be used with a fuel filter and characterized * by the fact that it comprises at least one malleable electrical resistance and a malleable strip wound around the resistance and designed to be wound around the filtered.
20 On comprendra mieux l'invention à la lecture de la description détaillée ci-après portant sur un mode d’exécution préférentiel de l'invention, donné à titre d'exemple non limitatif et représenté par les dessins annexés sur lesquels : 25 La figure 1 est une perspective par le haut d'un dispositif de chauffage selon l'invention, monté dans „ un exemple d'application, et r La figure 2 est un schéma électrique d'un circuit de commande du dispositif de la figure 1.The invention will be better understood on reading the detailed description below relating to a preferred embodiment of the invention, given by way of nonlimiting example and represented by the appended drawings in which: FIG. 1 is a perspective from above of a heating device according to the invention, mounted in „an example of application, and r Figure 2 is an electrical diagram of a control circuit of the device of Figure 1.
30 On considérera maintenant plus particulièrement la figure 1 ? la référence 1 indique généralement un dispositif de chauffage conçu pour être appliqué à un filtre à carburant 2. Le filtre à carburant 2 présente une structure pratiquement cylindrique et comprend un 35 corps inférieur pratiquement en cuvette 3 fermé à sa partie supérieure par un couvercle 4, le corps et le w ψ \ - 2 - : couvercle étant munis de conduits respectifs 5 et 6 • * servant à l'évacuation et à l'amenée du carburante30 We will now consider more particularly Figure 1? the reference 1 generally indicates a heating device designed to be applied to a fuel filter 2. The fuel filter 2 has a practically cylindrical structure and comprises a practically bowl-shaped lower body 3 closed at its upper part by a cover 4, the body and the w ψ \ - 2 -: cover being provided with respective conduits 5 and 6 • * used for the evacuation and the supply of fuel
Le dispositif de chauffage selon l'invention comprend essentiellement une résistance électrique indiquée par 5 la référence générale 8 et munie de bornes de connexion 9 et 10 et une bande malléable 11 entourant la résistance sur toute sa longueur et ne laissant libres que les bornes 9 et 10. En particulier, la bande 11 se compose de deux bandelettes planes 12 et 13 entre lesquelles est disposée 10 la résistance 8 ; la bandelette 13 présente en direction - transversale de multiples dents 14 qui sont courbées sur la bandelette 12 de manière à former une bande solidaire 11. Les extrémités opposées longitudinalement de la bande 13 sont courbées à 90° et forment des languettes respectives 15 15, 16 présentant chacune un trou passant (non représenté) dans lequel s'engage la tige d'un boulon 17. La résistance 8 et la bande 11 sont formées de matière déformable plastiquement de sorte que l'on peut enrouler la bande 11 autour de filtres de différents diamètres et l'adapter 20 à la forme des filtres.The heating device according to the invention essentially comprises an electrical resistance indicated by the general reference 8 and provided with connection terminals 9 and 10 and a malleable strip 11 surrounding the resistance over its entire length and leaving only the terminals 9 and 10. In particular, the strip 11 is composed of two flat strips 12 and 13 between which the resistor 8 is disposed; the strip 13 has in the transverse direction multiple teeth 14 which are curved on the strip 12 so as to form an integral strip 11. The longitudinally opposite ends of the strip 13 are curved at 90 ° and form respective tongues 15 15, 16 each having a through hole (not shown) in which engages the rod of a bolt 17. The resistor 8 and the strip 11 are formed from plastically deformable material so that the strip 11 can be wound around filters of different diameters and adapt it to the shape of the filters.
Sur le corps en cuvette 3 du filtre 2 est vissé un interrupteur thermique 19 qui comprend de façon non représentée un élément à bilame qui est habituellement ouvert quand la température du filtre est supérieure à 25 -5°C par exemple et qui se ferme quand la température est inférieure à ce niveau. De l'interrupteur thermique 19 partent deux cordons de connexion 21 et 22.On the bowl body 3 of the filter 2 is screwed a thermal switch 19 which comprises, not shown, a bimetallic element which is usually open when the temperature of the filter is above 25 -5 ° C for example and which closes when the temperature is below this level. From the thermal switch 19, two connection cords 21 and 22 leave.
On considérera maintenant particulièrement la figure 2 } entre les bornes 24 et 25 pouvant être reliées à 30 des pôles respectifs opposés d'une source d'énergie électrique sont branchées deux branches en parallèle dont la première comprend, en série, l'interrupteur thermique à bilame 19 et une bobine 26 d'un relais et dont la deuxième comprend, en série, la résistance 8 et 35 un contacteur 27 qui est actionné par la bobine 26. j Enfin, comme le montre la figure 1, autour de la - 3 - r bande 11 est disposée une bandelette 18 formée d'une , · matière calorifuge.We will now particularly consider FIG. 2} between the terminals 24 and 25 which can be connected to 30 of the respective opposite poles of an electric power source are connected two branches in parallel, the first of which comprises, in series, the thermal switch at bimetallic strip 19 and a coil 26 of a relay and the second of which comprises, in series, the resistor 8 and 35 a contactor 27 which is actuated by the coil 26. j Finally, as shown in FIG. 1, around the - 3 - Strip 11 is arranged a strip 18 formed of a heat-insulating material.
On effectue l'assemblage du dispositif de chauffage 1 d'une façon très simple en façonnant la bande 11 autour 5 du filtre 2 et en serrant les languettes 15 et 16 sur la bande 11 au moyen du boulon 17. On décrira maintenant le fonctionnement du dispositif en supposant que la température détectée par 1* interrupteur thermique 19 soit initialement inférieure à -5°C. Dans ces conditions et comme le montre 10 la figure 2, l'interrupteur thermique 19 est fermé, la * bobine 26 est activée et par conséquent le contacteur 27 est fermé. Donc, dans la résistance 8, il passe un courant électrique qui a pour effet de chauffer la résistance 8.The heating device 1 is assembled in a very simple way by shaping the strip 11 around the filter 2 and tightening the tabs 15 and 16 on the strip 11 by means of the bolt 17. We will now describe the operation of the device assuming that the temperature detected by the thermal switch 19 is initially less than -5 ° C. Under these conditions and as shown in FIG. 2, the thermal switch 19 is closed, the coil 26 is activated and therefore the contactor 27 is closed. Therefore, in the resistor 8, it passes an electric current which has the effect of heating the resistor 8.
On considérera à nouveau la figure 1 ; l'énergie 15 thermique engendrée par la résistance 8 se transmet au corps en cuvette 3 du filtre 2 et de celui-ci au carburant qui s'y écoule, causant ainsi une élévation graduelle de la température et facilitant la dissolution des particules de paraffine contenues dans le carburant.We will again consider Figure 1; the thermal energy generated by the resistor 8 is transmitted to the bowl-shaped body 3 of the filter 2 and of the latter to the fuel flowing therein, thereby causing a gradual rise in temperature and facilitating the dissolution of the paraffin particles contained in the fuel.
20 Quand la température devient supérieure au minimum préétabli (par exemple +5°C), l'interrupteur thermique 19 s'ouvre, ce qui interrompt l'alimentation de la bobine 26 et, par celle-ci, de la résistance 8. L'action combinée de la résistance 8 et de l'interrupteur thermique 19 25 permet en tout cas de maintenir la température à l'intérieur ’ du filtre 2 au-dessus du niveau minimal préétabli.20 When the temperature becomes higher than the preset minimum (for example + 5 ° C), the thermal switch 19 opens, which interrupts the supply of the coil 26 and, by this, of the resistor 8. L The combined action of the resistor 8 and of the thermal switch 19 makes it possible in any case to maintain the temperature inside the filter 2 above the preset minimum level.
D'après l'analyse des caractéristiques du dispositif r de chauffage 1 selon l'invention, on peut noter que celui-ci permet de surmonter les inconvénients susdits.According to the analysis of the characteristics of the heating device 1 according to the invention, it can be noted that this makes it possible to overcome the above-mentioned drawbacks.
30 En particulier, le dispositif selon l'invention est extrêmement facile à assembler et en outre, il s'adapte à n'importe quel type de filtre, à condition que le système d'accouplement entre les languettes 15 et 16 soit éventuellement modifié selon les dimensions du 35 filtre à chauffer. La structure extrêmement simple du dispositif 1 permet de réduire à un minimum le prix de I - - 4 - Γ - y revient de celui-ci tandis que le circuit de commande * ♦ correspondant, représenté par la figure 2, permet au dispositif 1 de fonctionner de façon entièrement automatique.In particular, the device according to the invention is extremely easy to assemble and, moreover, it adapts to any type of filter, provided that the coupling system between the tongues 15 and 16 is possibly modified according to the dimensions of the filter to be heated. The extremely simple structure of the device 1 makes it possible to reduce the price of I - - 4 - Γ - to a minimum therefrom while the corresponding control circuit * ♦, represented by FIG. 2, allows the device 1 to operate fully automatically.
5 Enfin, il est évident que l'on peut apporter de nombreuses modifications au dispositif de chauffage 1 et au circuit de commande électronique correspondant sans s'écarter du cadre de l'invention. Par exemple, on peut apporter de larges modifications à la structure du 10 filtre 2 ; en particulier, la bande 11 pourrait être formée d'un corps d'un seul tenant en caoutchouc de silicone et la résistance 8 pourrait être formée de plusieurs résistances en parallèle. On pourrait modifier “ largement le circuit de commande représenté par la figure 15 2, par exemple en disposant l'interrupteur 19 directement en série avec la résistance 8 ou en remplaçant l'interrupteur thermique 19 par un interrupteur à actionnement manuel placé sur le tableau de bord du véhicule automobile. Enfin, on peut appliquer le dispositif de chauffage 1 20 à n'importe quel filtre à carburant de véhicule automobile, en particulier aussi au filtre disposé autour du tuyau d'aspiration, à l'intérieur du réservoir à carburant du . véhicule et dans tout dispositif où le carburant circule,,Finally, it is obvious that many modifications can be made to the heating device 1 and to the corresponding electronic control circuit without departing from the scope of the invention. For example, large modifications can be made to the structure of filter 2; in particular, the strip 11 could be formed from a one-piece body made of silicone rubber and the resistor 8 could be formed from several resistors in parallel. We could modify “the control circuit shown in FIG. 15 2 to a large extent, for example by placing the switch 19 directly in series with the resistor 8 or by replacing the thermal switch 19 with a manually operated switch placed on the control panel. on board the motor vehicle. Finally, the heater 1 20 can be applied to any motor vehicle fuel filter, in particular also to the filter disposed around the suction pipe, inside the fuel tank. vehicle and in any device where fuel flows,
