Abstract
Description
L'objet de l'invention concerne un dispositif de réarmorçage automatique des circuits d'alimentation en hydrocarbure des moteurs de véhicules en cours de réparation. The object of the invention relates to an automatic reset device for the hydrocarbon supply circuits of vehicle engines under repair.
Il est destiné à se substituer en cas de défaillance aux pompes de réamorçage généralement utilisées à ces fins, et permettre de réaliser instantanément cette opération avec un autorégulateur de pression pour les moteurs diésel et à essence. It is intended to replace, in the event of failure, the priming pumps generally used for these purposes, and allow this operation to be carried out instantly with a pressure regulator for diesel and petrol engines.
Les travaux de réparation et d'entretien du circuit d'alimentation des moteurs à essence ou diésel à la suite de changement de filtre ou autres provoquent très souvent le désamorçage de la pompe. Il faut alors obtenir une circulation et l'arrivée du fluide jusqu'au point le plus élevé de l'installation. Repair and maintenance work on the fuel system of gasoline or diesel engines following a change of filter or others very often cause the pump to prime. It is then necessary to obtain a circulation and the arrival of the fluid to the highest point of the installation.
Jusqu'à ce jour le problème du désamorçage de la pompe exigeait l'emploi de moyens de fortune faisant perdre après la réparation un temps précieux aux professionnels.Up to now, the problem of defusing the pump has required the use of makeshift means making professionals lose precious time after the repair.
Le dispositif suivant l'invention supprime ces inconvénients et permet d'assurer automatiquement le réamorçage des circuits et assurer d'une façon immédiate l'arrivée à une pression régulée de l'hydrocarbure contenu dans le réservoir, soit aux injecteurs, soit au carburateur. The device according to the invention eliminates these drawbacks and makes it possible to automatically restart the circuits and immediately ensure the arrival at a regulated pressure of the hydrocarbon contained in the tank, either at the injectors or at the carburetor.
Il est constitué par la combinaison d 'un compresseur et d'un régulateur à membrane mettant le réservoir sous la pression nécessaire pour la propulsion des hydrocarbures dans les circuits d'alimentation. It consists of the combination of a compressor and a membrane regulator putting the tank under the pressure necessary for the propulsion of hydrocarbons in the supply circuits.
Sur les dessins annexés, donnés à titre d'exemple non limitatif, d'une des formes de réalisation de l'objet de l'invention
La figure 1 représente vu en élévation et en coupe, le dispositif régulateur automatique de pression.In the accompanying drawings, given by way of nonlimiting example, of one of the embodiments of the subject of the invention
Figure 1 shows in elevation and in section, the automatic pressure regulator device.
La figure 2 montre dans les mêmes conditions le fonctionnement du régulateur. Figure 2 shows in the same conditions the operation of the regulator.
Les figures 3 et 4 montrent vu en élévation et en coupe deux variantes de construction du même dispositif. Figures 3 and 4 show in elevation and in section two variants of construction of the same device.
Le dispositif suivant la figure 1 comporte sur le réservoir d'hydrocarbure 1 du véhicule, un injecteur d'air 2 avec valve. Cet air sous pression après avoir rempli le réservoir est amené par le conduit 3 dans la chambre inférieure 4 du régulateur automatique. The device according to Figure 1 comprises on the hydrocarbon tank 1 of the vehicle, an air injector 2 with valve. This pressurized air after filling the tank is brought through line 3 into the lower chamber 4 of the automatic regulator.
L'étanchéité de la chambre 4 est assurée par la membrane déformable 5 serrée par son support 6 entre la chambre 4 et la capacité supérieure 7 en contact avec 1' air libre. The sealing of the chamber 4 is ensured by the deformable membrane 5 clamped by its support 6 between the chamber 4 and the upper capacity 7 in contact with the free air.
Cette membrane est stabilisée dans sa partie centrale par les deux disques 8, 9 recourbés à leur périphérie pour effectuer un cisaillement lors des mouvements. This membrane is stabilized in its central part by the two discs 8, 9 bent at their periphery to effect shearing during movements.
L'axe du support immobilise un élément tubulaire 10 porteur d'une valve 11, au repos le pontet 12 appuie sur la vis de réglage 13 qui limite la course de l'ensemble mobile en fonctionnement sous l'effet de la pression, l'ensemble membrane et valve s'élève et comprime le ressort antagoniste 14. The axis of the support immobilizes a tubular element 10 carrying a valve 11, at rest the trigger guard 12 presses on the adjustment screw 13 which limits the stroke of the mobile assembly in operation under the effect of the pressure, the membrane and valve assembly rises and compresses the opposing spring 14.
La valve 11 coulisse dans le guide 15 dont le filetage permet le réglage de la course en hauteur;
Lorsque la pression atteint le niveau désiré et avant que la valve 11 ne touche le fond du guide 15 (figure 2), l'aiguille 16 de la valve 11 bute sur l ' ergot central 17. L'air contenu dans la cuvette 4 s'échappe par les orifices 18 du guide.The valve 11 slides in the guide 15, the thread of which allows the height stroke to be adjusted;
When the pressure reaches the desired level and before the valve 11 touches the bottom of the guide 15 (Figure 2), the needle 16 of the valve 11 abuts on the central lug 17. The air contained in the bowl 4 s 'escapes through the holes 18 of the guide.
La rondelle 19 placée sur le ressort 14 est aménagée pour obtenir par l'intermédiaire du levier articulé 20 des variations de tension sur la membrane afin de modifier la pression suivant les nécessités du travail. The washer 19 placed on the spring 14 is arranged to obtain, by means of the articulated lever 20, variations in tension on the membrane in order to modify the pressure according to the requirements of the work.
En plaçant le levier 20 sur l'indication choisie sur le cadran 21 on obtient la pression désirée. By placing the lever 20 on the indication chosen on the dial 21, the desired pressure is obtained.
Suivant la variante d'exécution de la figure 3, la valve 22 qui alimente en air le réservoir de carburant 1 est directement fixée sur le carter supérieur de l'appareil et, est reliée par le conduit 23, qu'on fixe sur un embout de raccordement intégré au dit réservoir. According to the alternative embodiment of FIG. 3, the valve 22 which supplies air to the fuel tank 1 is directly fixed on the upper casing of the appliance and is connected by the conduit 23, which is fixed on a nozzle. connection integrated to said tank.
L'air sous pression passe par l'ajutage 2, puis par la valve 23. I1 ressort du réservoir par la canalisation souple 25 et pénètre dans la chambre 4 dans laquelle se trouve la membrane souple 5. The pressurized air passes through the nozzle 2, then through the valve 23. I1 leaves the reservoir through the flexible pipe 25 and enters the chamber 4 in which the flexible membrane 5 is located.
L'échappen.ent d'air s'effectue exactement comme le décrit les figures 1 et 2, par la chambre 7. The air escape takes place exactly as described in FIGS. 1 and 2, through the chamber 7.
L'adrr,ission d'air dans le réservoir 1 suivant la figure 4 s'effectue par le circuit 26. Par contre, l'arrivée d'air sous pression est branché sur l'embout 27. L'échappement prévu s'effectue toujours par le même procédé dans le conduit 28. The addition of air to the tank 1 according to FIG. 4 is carried out by the circuit 26. On the other hand, the supply of pressurized air is connected to the nozzle 27. The intended exhaust is carried out always by the same process in line 28.
On a ainsi un réamorçage automatique des circuits d'alimentation en carburant des moteurs de toutes natures sans avoir à utiliser les pompes de réamorçage dont le fonctionnement ne permet généralement pas d'effectuer instantanément cette opération. There is thus an automatic priming of the fuel supply circuits of engines of all kinds without having to use the priming pumps whose operation generally does not allow this operation to be carried out instantaneously.
Toutefois les formes, dimensions et dispositions des différents éléments avec d ' ailleurs les matières utilisées pour leur fabrication, pourront varier dans la limite des équivalents, sans changer pour cela, la conception générale de l'invention qui vient d'être décrite. However, the shapes, dimensions and arrangements of the various elements with, moreover, the materials used for their manufacture, may vary within the limit of the equivalents, without changing the general conception of the invention which has just been described.
