Connecting units connect the reservoir by a cylindrical element to a base (8) fixed on the vehicle, and a synthetic envelope (10) protects the reservoir from a solar radiation. The reservoir has shape of parallelepiped, cylindrical or spherical, and is made of steel, and the envelope is made of synthetic material.

Description

-1- -1-

La présente invention concerne un réservoir gaz amovible qui permet sa pose ou sa dépose selon les besoins de son utilisateur. The present invention relates to a removable gas tank that allows its installation or removal according to the needs of its user.

Pour transformer un véhicule essence en bi carburation essence / gaz, on a l'obligation d'aménager un réservoir a demeure sur l'arrière du véhicule avec un orifice de remplissage sur 5 l'aile. La pose du réservoir ainsi que la vanne de remplissage sont les postes les plus importants de la transformation, du fait du prix du réservoir et du coût de la main d'oeuvre pour la pose. Hormis le coût, le réservoir se retrouve dans le coffre avec tous les inconvénients que cela comporte, la réduction du volume du coffre avec la peur de certaine personne à être dans le même habitacle qu'un réservoir sous pression, pour éviter ces désagréments on trouve quelques 10 fois un réservoir torique à la place de la roue de secours ce qui revient à mettre la roue dans le coffre de la voiture mais le point noir reste le remplissage car on a l'obligation de se rendre dans une des très rares stations GNV ou GPL. In order to transform a gasoline vehicle into gas / gas carburetion, it is necessary to arrange an indwelling reservoir on the rear of the vehicle with a filling orifice on the wing. The installation of the tank and the filling valve are the most important items of the transformation, because of the price of the tank and the cost of labor for the installation. Apart from the cost, the tank is found in the trunk with all the disadvantages that this entails, the reduction of the volume of the trunk with the fear of some person to be in the same cockpit as a tank under pressure, to avoid these inconveniences can be found some 10 times a tank in place of the spare wheel which is to put the wheel in the trunk of the car but the black spot is the filling because we have the obligation to visit a very rare CNG stations or LPG.

Ce système est adaptable sur tous les véhicules à moindre frais, car il limite considérablement la main d'oeuvre ainsi que le prix du matériel. This system is adaptable on all vehicles at a lower cost, because it limits considerably the manpower as well as the price of the material.

15 La nouveauté est que le réservoir à l'arrière du véhicule est sûpprimé ainsi que la vanne de remplissage au profit d'un petit réservoir de gaz qui se fixe sur le capot avant de la voiture. Il devient un réservoir amovible que l'on change quand on veut faire le plein de gaz ou que l'on rempli à la station selon ses besoins. Son faible poids d'une quinzaine de kilos permet à son propriétaire de le mettre en place ou non suivant son choix de carburation. Il peut être enlevé dés 20 que le véhicule est immobilisé, la nuit par exemple pour le remettre en fonction le lendemain matin, cette manoeuvre fait de ce système un anti vol naturel et la meilleure protection contre le vol (car si on lève le carburant, la voiture ne peut plus se déplacer), il suffit pour cela que le propriétaire décide de ne fonctionner qu'au gaz pour ces petits déplacements urbain. The novelty is that the tank at the rear of the vehicle is repressed and the filling valve in favor of a small gas tank that attaches to the front hood of the car. It becomes a removable tank that we change when we want to refuel or filled at the station according to his needs. Its low weight of fifteen kilos allows its owner to set up or not according to his choice of carburetion. It can be removed as soon as the vehicle is immobilized, at night for example to put it back into operation the next morning, this maneuver makes this system a natural anti-theft and the best protection against theft (because if you lift the fuel, the car can no longer move), it suffices for the owner to decide to run only on gas for these small urban journeys.

On a décrit ci-après a titre d'exemple non limitatif un mode de réalisation d'un réservoir selon 25 l'invention avec référence aux dessins annexés dans lesquels : An embodiment of a reservoir according to the invention is described below by way of nonlimiting example with reference to the accompanying drawings, in which:

La figure 1 est une vue en perspective avec la coupe du réservoir, de la chambre et de l'enveloppe de protection. Le réservoir est raccordé à son embase. Figure 1 is a perspective view with the section of the tank, the chamber and the protective envelope. The tank is connected to its base.

La figure 2 même vue sans enveloppe, le réservoir est déposé de son embase. La figure 3 est une vue en perspective avec coupe de l'embase. Figure 2 even seen without envelope, the tank is removed from its base. Figure 3 is a perspective view with section of the base.

30 La figure 4 est une vue en perspective de l'électrovanne et de là tige d'acier avec coupe du cylindre creux et de l'embase. Figure 4 is a perspective view of the solenoid valve and steel rod with cut of the hollow cylinder and the base.

La figure 5 est une vue en plan du guide avec la coupe du cylindre creux et de la tige. Figure 5 is a plan view of the guide with the section of the hollow cylinder and the rod.

Ce petit réservoir (1) de forme parallélépipède, cylindrique ou sphérique sera réalisé en acier dans un premier temps pour être transformé en matériau composite rapidement. Ce 35 réservoir qui contient une dizaine de litres de gaz en haute pression a la particularité de ne délivré en sortie qu'un bar de pression, pour cela on a placé à l'interne un détendeur à gaz (2) compact à débit prédéfinie (fig.1) ce qui permet de limiter tous les risques de la haute pression lors de la pose / dépose du réservoir ainsi que les fuites. -2- A la suite du détendeur, il a été créé une petite chambre (3) qui est fixée sur le fond du réservoir et qui laisse apparaître en dehors un cylindre creux qui permet le raccordement du réservoir (fig.1) à son embase. Lorsque le réservoir est raccordé (fig 1) une tige centrée par deux guides à l'intérieur du cylindre creux (6), pousse une bille (5), cette action comprime un ressort (11), et libère le passage du gaz, de la chambre jusqu'à l'électrovanne (12). Lors de la dépose du réservoir (fig.2), ce ressort se détend en déplaçant la bille qui vient prendre appui sur la partie inferieure de la chambre pour stopper le passage du gaz. La chambre est recouverte d'une couche de téflon ou d'un matériau similaire pour renforcer l'étanchéité lors de l'obturation par cette bille. Sur le coté se trouve un embout normalisé (15) pour remplir le réservoir. This small tank (1) of parallelepipedal shape, cylindrical or spherical will be made of steel at first to be converted into a composite material quickly. This tank, which contains about ten liters of gas at high pressure, has the particularity of outputting only a pressure bar, for which purpose a compact gas regulator (2) with a predefined flow rate has been placed internally ( fig.1) which makes it possible to limit all the risks of the high pressure during the installation / removal of the tank as well as the leaks. -2- Following the regulator, it was created a small chamber (3) which is fixed on the bottom of the tank and which reveals outside a hollow cylinder which allows the connection of the tank (fig.1) to its base . When the reservoir is connected (FIG. 1) a rod centered by two guides inside the hollow cylinder (6), pushes a ball (5), this action compresses a spring (11), and releases the passage of the gas, the chamber to the solenoid valve (12). When removing the tank (fig.2), this spring relaxes by moving the ball that bears on the lower part of the chamber to stop the passage of gas. The chamber is covered with a layer of Teflon or similar material to reinforce the seal during sealing by this ball. On the side is a standard nozzle (15) to fill the tank.

Sur le dessus du réservoir se trouve une pièce démontable (16) pour accédera l'intérieur du réservoir, sur cette pièce a été placé une soupape de sécurité (18) et un manomètre (17). Une embase (8) en alu brossé d'une dizaine de centimètre, équipé d'une électrovanne est fixé a demeure sur le véhicule, ce pack, embase/électrovanne font parties de la même pièce, cette association limite considérablement les parties sous pression. Dans le fond de l'embase, le filetage (9) de l'électrovanne dépasse de quelques centimètres pour permettre le raccordement du réservoir, un joint torique (13) est disposé autour du filetage pour assurer une bonne étanchéité. Trois trous (14) sont disposés sur le fond de l'embase pour éviter que l'eau reste à l'intérieur. Ce réservoir sera protégé par une enveloppe synthétique (10) est isolante pour limiter la montée en pression du gaz dû au rayonnement direct du soleil. On the top of the tank is a removable piece (16) to access the inside of the tank, on this piece was placed a safety valve (18) and a pressure gauge (17). A base (8) in brushed aluminum of about ten centimeters, equipped with a solenoid valve is permanently attached to the vehicle, this pack, base / solenoid valve are part of the same part, this combination considerably limits the parts under pressure. In the base of the base, the thread (9) of the solenoid valve exceeds a few centimeters to allow the connection of the tank, an O-ring (13) is arranged around the thread to ensure a good seal. Three holes (14) are arranged on the bottom of the base to prevent the water remains inside. This tank will be protected by a synthetic envelope (10) is insulating to limit the rise in gas pressure due to direct sunlight.

II en va de soi que la présente invention ne doit pas être considérée comme limité au mode de réalisation ou d'utilisation décrit et représenté mais couvre, au contraire, toutes les variantes du réservoir amovible. C'est ainsi que lorsque ce réservoir que l'on vient de décrire dans sa version recharge, une autre variante du réservoir possède un limiteur de remplissage à 80% pour que les clients puisse faire le plein en station, non plus limité à des raisons esthétiques, comme, dissimuler l'embase ou donner une autre forme à l'enveloppe de protection. On fait ci-dessus la description d'un réservoir qui alimente un véhicule mais ce système peut aussi alimenter tous les types de moteurs, qu'ils fonctionnent en bicarburation ou au gaz uniquement, on peut ainsi alimenter des groupes électrogènes, des pompes, des compresseurs 30 It goes without saying that the present invention should not be considered as limited to the embodiment or use described and shown but covers, on the contrary, all variants of the removable tank. Thus, when this tank, which has just been described in its refueling version, another variant of the tank has a filling limiter at 80% so that customers can refuel in the station, no longer limited to reasons aesthetic, like, conceal the base or give another form to the protective envelope. Above is the description of a tank that supplies a vehicle but this system can also supply all types of engines, whether they operate in bi-fuel or gas only, it can thus feed generators, pumps, compressors 30
