Abstract
Description
La présente invention concerne un procédé d'intervention sur circuit hydraulique de véhicule, et plus particulièrement un procédé de remplissage ou de vidange et remplissage de circuit de freinage et/ou d'embrayage ; elle concerne également la station d'intervention pour la miseen oeuvre du procédé. The present invention relates to a method of intervention on a vehicle hydraulic circuit, and more particularly to a method of filling or draining and filling the braking and / or clutch circuit; it also relates to the intervention station for implementing the method.
Cette station vise aussi bien à effectuer un remplissage de circuit vide qu'à effectuer un remplacement de liquide usagé. This station aims to fill an empty circuit as well as to replace a used liquid.
I1 est en effet nécessaire de changer régulièrement le liquide de freinage sur les véhicules car il se détériore assez rapidement, perd ses qualités et il est fréquent de voir se former des dépots qui altèrent les parois des organes du circuit. La vidange des circuits visant à remplacer totalement le liquide est une opération délicate à mener si le produit est fortement altéré. Dans la majorité des cas, elle s'effectue en se servant de la pédale de frein, ou d'embrayage, comme pompe pour vider puis pour remplir le circuit et de plus l'opération de purge, nécessite deux personnes. Cette opération est délicate car bien souvent, l'usage de la pédale pour chasser le liquide entraine des détériorations du maitre cylindre et des coupelles lorsque l'on déplace la pédale au-delà de sa course habituelle. I1 is indeed necessary to regularly change the brake fluid on vehicles because it deteriorates fairly quickly, loses its qualities and it is common to see deposits forming which alter the walls of the organs of the circuit. Draining the circuits to completely replace the liquid is a delicate operation to carry out if the product is severely altered. In most cases, it is done using the brake pedal, or clutch, as a pump to empty then to fill the circuit and moreover the purge operation, requires two people. This operation is delicate because very often, the use of the pedal to chase the liquid causes damage to the master cylinder and the cups when the pedal is moved beyond its usual stroke.
L'invention vise à réduire ces risques de dégradations accidentelles des organes du circuit de freinage d'une part, mais elle vise aussi à permettre cette intervention d'une manière beaucoup plus rapide, avec une seule personne, de façon très efficace et en tous lieux, d'autre part. The invention aims to reduce these risks of accidental damage to the organs of the braking circuit on the one hand, but it also aims to allow this intervention in a much faster manner, with a single person, very effectively and in all places, on the other hand.
Selon l'invention, la station d'intervention est constituée : - d'un récipient portable contenant le liquide adapté au type de circuit et d'intervention, - d'une moto-pompe de mise en circulation du liquide sous pression, - d'un chapeau étanche d'adaptation sur le réservoir de liquide du circuit du véhicule. According to the invention, the intervention station consists of: - a portable container containing the liquid suitable for the type of circuit and intervention, - a motor pump for circulating the pressurized liquid, - d '' a tight fitting cap on the liquid tank of the vehicle circuit.
Selon une disposition préférentielle de l'invention, la moto-pompe est alimentée directement sur la batterie d'accumulateurs du véhicule. According to a preferred arrangement of the invention, the motor-pump is supplied directly from the vehicle's storage battery.
Selon une autre disposition de l'invention, la pression du liquide envoyée par la moto-pompe est limitée par une soupape régulatrice ou directement par les capacités de la pompe. According to another arrangement of the invention, the pressure of the liquid sent by the motor-pump is limited by a regulating valve or directly by the capacities of the pump.
L'invention sera mieux comprise à l'aide de la description et du dessin annexé donné à titre indicatif. The invention will be better understood with the aid of the description and of the appended drawing given for information.
Tel que représenté, la station d'intervention est constituée d'un récipient 1 portable contenant le liquide 2 destiné aux circuits hydrauliques de freinage et/ou d'embrayage pour véhicules. As shown, the intervention station consists of a portable container 1 containing the liquid 2 intended for hydraulic braking and / or clutch circuits for vehicles.
A l'intérieur du récipient 1 on trouve une moto-pompe 3 immergée dans le liquide 2 et maintenue au fond par tous moyens appropriés. Le fait de maintenir la moto-pompe immergée présente l'avantage de refroidir automatiquement son moteur par échange avec la masse de liquide du récipient 1. Ce moteur de la pompe 3 est alimenté par un cordon 4, directement sur la batterie d'accumulateurs du véhicule ce qui permet, dans un garage par exemple, d'effectuer une intervention en tous endroits. La pompe 3 débite le liquide sous pression à travers une conduite 5 dont l'extrémité est raccordée à un chapeau étanche 6 pouvant s'adapter sur le réservoir d'alimentation 7 du circuit de freinage 8. Inside the container 1 there is a motor-pump 3 immersed in the liquid 2 and held at the bottom by all appropriate means. Keeping the motor-pump submerged has the advantage of automatically cooling its motor by exchange with the mass of liquid in container 1. This motor of pump 3 is supplied by a cord 4, directly on the storage battery of the vehicle which allows, in a garage for example, to carry out an intervention in all places. The pump 3 delivers the liquid under pressure through a line 5, the end of which is connected to a sealed cap 6 which can be fitted to the supply tank 7 of the braking circuit 8.
Pour éviter toute déformation du réservoir 7, la pression du liquide envoyé par la pompe est limitée soit au moyen d'une soupape régulatrice de pression, soit directement par les capacités de la pompe elle-meme. To avoid any deformation of the reservoir 7, the pressure of the liquid sent by the pump is limited either by means of a pressure regulating valve, or directly by the capacities of the pump itself.
Le procédé d'intervention sur le circuit, pour le remplir s'il est vide ou encore pour réaliser sa vidange et son remplissage, est le suivant - on met en place le chapeau étanche 6 sur le réservoir 7 d'alimentation du circuit - on branche le cordon d'alimentation de la moto-pompe 3 sur la batterie du véhicule pour amener sous pression le liquide 2 du récipient 1, dans le réservoir 7 du circuit 8 - on ouvre la purge pour laisser s'échapper l'air, si le circuit était vide, ou le liquide usagé si l'on effectue un remplacement - on referme la purge dès que le circuit est vide d'air ou rempli de liquide neuf - on débranche l'alimentation de la moto-pompe 3 et le chapeau étanche 6. The intervention procedure on the circuit, to fill it if it is empty or to carry out its emptying and filling, is as follows - the waterproof cap 6 is put in place on the circuit supply tank 7 - we connect the power cord of the motor-driven pump 3 to the vehicle battery to bring the liquid 2 from the container 1 under pressure into the tank 7 of the circuit 8 - the purge is opened to let the air escape, if the circuit was empty, or the used liquid if a replacement is carried out - the purge is closed as soon as the circuit is empty of air or filled with new liquid - the power supply to the motor-driven pump 3 and the cap is disconnected waterproof 6.
Lorsqu'il s'agit d'un circuit de freinage, l'opération de purge s'effectue successivement sur chacune des vis de purge. In the case of a braking circuit, the bleeding operation is carried out successively on each of the bleeding screws.
L'invention ne se limite aucunement au mode de réalisation décrit, elle embrasse toutes les variantes. The invention is in no way limited to the embodiment described, it embraces all variants.
C'est ainsi que l'on peut prévoir une moto-pompe 3 flottante à la surface du liquide 2, pour lui assurer un bon refroidissement et lui éviter d'être totalement noyée dans un liquide parfois très corrosif comme les liquides employés dans les circuits de freinage. La pompe 3 pourra même être située en-dehors du récipient 1. This is how one can provide a motor-pump 3 floating on the surface of the liquid 2, to ensure good cooling and to prevent it from being completely drowned in a liquid which is sometimes very corrosive like the liquids used in the circuits. braking. The pump 3 may even be located outside of the container 1.
De meme, l'usage d'une telle station ne se limite pas aux seuls circuits de freinage et/ou d'embrayage, elle peut dans certains cas etre utilisée pour vidanger des circuits de carburant par exemple en adaptant le chapeau étanche 6. Likewise, the use of such a station is not limited to only the braking and / or clutch circuits, it can in certain cases be used to drain fuel circuits, for example by adapting the waterproof cap 6.
