Description
La présente invention concerne un réservoir de combustible gazeux en phase liquide et plus particulièrement un réservoir amovible ou cartouche pour appareil utilisant la combustion de ce gaz.The present invention relates to a gaseous fuel tank in the liquid phase and more particularly to a removable tank or cartridge for an apparatus using the combustion of this gas.
Un tel réservoir, qui est, généralement, de forme cylindrique, présente un orifice de remplissage au centre de son fond et, à son extrémité opposée au fond, un orifice de soutirage équipé d'un organe de soutirage tel qu'un clapet et d'un réducteur de pression évaporateur, tel qu'un élément poreux de perméabilité adaptée au débit recherché.Such a tank, which is generally of cylindrical shape, has a filling orifice in the center of its bottom and, at its end opposite the bottom, a withdrawal orifice equipped with a withdrawal member such as a valve and d 'An evaporator pressure reducer, such as a porous element of permeability adapted to the desired flow rate.
L'objectif à atteindre est de stocker, dans ce réservoir, la plus grosse quantité de combustible en phase liquide, sans qu'il soit possible que la phase liquide atteigne le réducteur de pression, ce qui provoquerait des crachements nuisibles au bon fonctionnement de l'appareil sur lequel est monté ce réservoir.The objective to be achieved is to store, in this tank, the largest quantity of fuel in the liquid phase, without it being possible for the liquid phase to reach the pressure reducer, which would cause spitting detrimental to the proper functioning of the device on which this tank is mounted.
Une solution consiste à stocker le combustible liquéfié dans un absorbant dans lequel il est retenu à l'état liquide par des forces capillaires. L'absorbant est caractérisée par sa nature et sa densité ; il peut aussi être caractérisé, en utilisation, par l'ascension capillaire du liquide absorbé lorsque l'équilibre est atteint, c'est-à-dire lorsque les forces de gravité sont équilibrées par les forces capillaires.One solution is to store the liquefied fuel in an absorbent in which it is retained in the liquid state by capillary forces. The absorbent is characterized by its nature and density; it can also be characterized, in use, by the capillary rise of the absorbed liquid when equilibrium is reached, that is to say when the gravity forces are balanced by the capillary forces.
Le document EP-A-0 202 172 concerne un réservoir pour gaz liquide, entièrement rempli d'un matériau absorbant, à l'intérieur duquel est ménagée une cheminée centrale perforée dans laquelle est engagé avec jeu un tube plongeur destiné à la sortie du gaz hors du réservoir.Document EP-A-0 202 172 relates to a tank for liquid gas, completely filled with an absorbent material, inside which is provided a perforated central chimney in which is engaged with clearance a dip tube intended for the outlet of the gas out of the tank.
Le document EP-A-0 447 330 concerne un réservoir de combustible stocké en phase liquide, le combustible étant piégé au sein d'une matière poreuse ou fibreuse remplissant le réservoir. Ce réservoir comprend un tube plongeur reliant l'orifice de sortie au centre du réservoir.Document EP-A-0 447 330 relates to a fuel tank stored in the liquid phase, the fuel being trapped within a porous or fibrous material filling the tank. This tank includes a tube plunger connecting the outlet to the center of the tank.
Un certain nombre de milieux absorbants ont été testés et l'ascension capillaire mesurée est de l'ordre de 100 mm. Cette hauteur d'ascension capillaire détermine donc, en fonction des autres dimensions du volume de l'absorbant, la capacité maximum de liquide absorbé.A certain number of absorbent media have been tested and the capillary rise measured is of the order of 100 mm. This capillary rise height therefore determines, according to the other dimensions of the volume of the absorbent, the maximum capacity of absorbed liquid.
Si la plus grande dimension du réservoir est supérieure à cette valeur de 100 mm, il n'est pas possible de remplir le réservoir au-delà de cette capacité maximum sans courir le risque d'avoir du combustible en phase liquide libre qui peut atteindre le réducteur de pression, notamment si le réservoir est tenu avec son orifice de soutirage en position basse.If the largest size of the tank is greater than this value of 100 mm, it is not possible to fill the tank beyond this maximum capacity without running the risk of having fuel in free liquid phase which can reach the pressure reducer, especially if the tank is held with its tapping hole in the low position.
Le but de l'invention est de fournir un réservoir de combustible gazeux en phase liquide, comportant un volume de gaz liquide en excès par rapport au volume absorbé par un matériau absorbant, et dans lequel la phase liquide n'atteint pas le réducteur de pression, même après retournement du réservoir, mouvement au cours duquel une certaine partie de gaz liquide est désorbée, c'est-à-dire n'est plus retenue par le matériau absorbant.The object of the invention is to provide a gas fuel tank in the liquid phase, comprising a volume of liquid gas in excess relative to the volume absorbed by an absorbent material, and in which the liquid phase does not reach the pressure reducer. , even after inverting the tank, movement during which a certain portion of liquid gas is desorbed, that is to say is no longer retained by the absorbent material.
A cet effet, le réservoir qu'elle concerne, du type comportant une paroi cylindrique allongée fermée par deux fonds transversaux, l'un inférieur et l'autre supérieur pourvu d'un orifice de soutirage équipé d'un organe de soutirage tel qu'un clapet et d'un réducteur de pression, son volume intérieur étant occupé par un milieu absorbant, est caractérisé en ce qu'une chambre est ménagée au-dessus du milieu absorbant, entre celui-ci et le fond supérieur du réservoir, dont le volume est au moins égal au volume de combustible en phase liquide en excès augmenté du volume de combustible liquide libéré par le milieu absorbant après retournement du réservoir et en ce que l'orifice de soutirage est équipé d'un tube de soutirage, d'alésage fin, placé en amont du réducteur de pression-évaporateur, logé axialement dans la chambre haute, et dont la longueur est au moins égale à la hauteur de combustible en phase liquide pouvant se trouver dans cette chambre lorsque le réservoir est en position renversée.To this end, the reservoir which it concerns, of the type comprising an elongated cylindrical wall closed by two transverse bottoms, one lower and the other upper provided with a withdrawal orifice equipped with a withdrawal member such as a valve and a pressure reducer, its internal volume being occupied by an absorbent medium, is characterized in that a chamber is provided above the absorbent medium, between the latter and the upper bottom of the reservoir, the volume is at least equal to the volume of excess liquid phase fuel increased by the volume of liquid fuel released by the absorbent medium after inversion of the tank and in that the withdrawal orifice is equipped with a withdrawal or bore tube end, placed upstream of the reduction gear pressure-evaporator, housed axially in the upper chamber, and whose length is at least equal to the height of fuel in liquid phase which may be in this chamber when the tank is in the inverted position.
Lorsque le réservoir est renversé, l'excédant de combustible en phase liquide occupe la chambre située entre le milieu absorbant et le fond supérieur du réservoir, sans atteindre l'extrémité libre du tube de soutirage.When the tank is overturned, the excess fuel in the liquid phase occupies the chamber located between the absorbent medium and the upper bottom of the tank, without reaching the free end of the withdrawal tube.
Suivant une forme de réalisation de ce réservoir, le milieu absorbant est constitué par de la fibre non tissée à base de cellulose.According to one embodiment of this reservoir, the absorbent medium consists of non-woven fiber based on cellulose.
Avantageusement, afin de réduire le temps d'absorption du combustible en phase liquide par le milieu absorbant, un canal central d'absorption est ménagé suivant l'axe longitudinal du milieu absorbant.Advantageously, in order to reduce the time of absorption of the fuel in liquid phase by the absorbent medium, a central absorption channel is formed along the longitudinal axis of the absorbent medium.
A l'aide d'un tel canal, il est possible d'obtenir une vitesse d'absorption de l'ordre de 35 cm³/mn. Dans une telle configuration, lorsque le réservoir passe d'une position renversée à une position droite, le temps nécessaire à l'absorption du liquide qui avait été précédemment libéré par le milieu absorbant, est considérablement réduite. Cet agencement élimine tout risque de voir l'extrémité libre du tube de soutirage immergée même momentanément par du combustible en phase liquide.Using such a channel, it is possible to obtain an absorption speed of the order of 35 cm³ / min. In such a configuration, when the reservoir passes from an inverted position to an upright position, the time necessary for the absorption of the liquid which had previously been released by the absorbent medium is considerably reduced. This arrangement eliminates any risk of seeing the free end of the withdrawal tube immersed even momentarily by fuel in the liquid phase.
Avantageusement, le tube de soutirage est disposé dans l'axe du canal central du milieu absorbant, et son extrémité libre est disposée dans le plan de la face supérieure du matériau absorbant.Advantageously, the withdrawal tube is arranged in the axis of the central channel of the absorbent medium, and its free end is arranged in the plane of the upper face of the absorbent material.
Selon une possibilité, la face supérieure du matériau absorbant est constituée par une surface conique dont le sommet est tourné du côté du fond inférieur du réservoir.According to one possibility, the upper face of the absorbent material consists of a conical surface, the top of which is turned towards the side of the bottom of the tank.
De toute façon l'invention sera bien comprise à l'aide de la description qui suit en référence au dessin schématique annexé représentant, à titre d'exemples non limitatifs, deux formes d'exécution de ce réservoir :In any case, the invention will be clearly understood with the aid of the description which follows with reference to the appended diagrammatic drawing representing, by way of nonlimiting examples, two embodiments of this reservoir:
Figures 1 et 2 sont deux vues en coupe longitudinale d'une première forme d'exécution de ce réservoir, respectivement en position debout et en position renversée .Figures 1 and 2 are two views in longitudinal section of a first embodiment of this tank, respectively in the upright position and in the inverted position.
Figures 3 et 4 sont deux vues en coupe d'un second réservoir respectivement en position debout et en position renversée.Figures 3 and 4 are two sectional views of a second tank respectively in the upright position and in the inverted position.
Figure 5 est une vue d'une variante du réservoir de figure 1.Figure 5 is a view of a variant of the tank of Figure 1.
Comme montré au dessin, le réservoir de combustible stocké en phase liquide suivant l'invention comporte une paroi cylindrique allongée 2 fermée à ses extrémités par deux fonds circulaires respectivement un fond circulaire inférieur 3 et un fond circulaire supérieur 4.As shown in the drawing, the fuel tank stored in the liquid phase according to the invention comprises an elongated
Le fond inférieur 3 est pourvu d'un orifice de remplissage 5 d'un type connu et par conséquent non décrit en détail. Le fond supérieur 4 présente, outre des moyens de raccordement à l'appareil que ce réservoir est destiné à alimenter, un orifice de soutirage 6 équipé de manière connue en soi d'un organe de soutirage tel qu'un clapet 7 et d'un réducteur de pression-évaporateur 8.The lower bottom 3 is provided with a
Dans l'exemple illustré au dessin, les moyens de raccordement de ce réservoir à l'appareil à alimenter sont constitués par une virole cylindrique 9 filetée extérieurement. En outre, comme montré au dessin, l'intérieur du réservoir est occupé, à partir de son fond inférieur 3, et sur une longueur L1, d'un milieu absorbant 11. Entre le fond supérieur 4 du réservoir et le milieu absorbant 11 est ménagée une chambre 12 s'étendant sur une longueur L2. Le volume de la chambre 12 est au moins égal au volume de combustible en phase liquide en excès, c'est-à-dire non absorbé par le milieu 11, augmenté du volume de combustible liquide libéré par le milieu absorbant, après retournement du réservoir.In the example illustrated in the drawing, the means for connecting this reservoir to the device to be supplied are constituted by a
Selon une autre caractéristique de l'invention, un tube de soutirage 13 équipe l'orifice de soutirage, en amont du réducteur de pression évaporateur 8. Ce tube 13 est disposé axialement dans le réservoir, et sa longueur 1 est au moins égale à la hauteur de combustible en phase liquide pouvant se trouver dans la chambre 12 lorsque le réservoir est en position renversée, comme montré à la figure 2.According to another characteristic of the invention, a
Ainsi, que le réservoir se trouve en position droite, comme montré à la figure 1 ou en position retournée comme montré à la figure 2, l'extrémité 13a du tube de soutirage n'est jamais immergée dans le combustible liquide, de telle sorte que la phase liquide n'atteint pas le réducteur de pression, assurant ainsi un excellent fonctionnement à l'appareil sur lequel est monté le réservoir.Thus, whether the reservoir is in an upright position, as shown in FIG. 1 or in an inverted position as shown in FIG. 2, the
Dans la forme d'exécution représentée aux figures 3 et 4, dans laquelle les mêmes éléments sont désignés par les mêmes références que précédemment, un canal central et axial s'étend sur toute la longueur L1 du milieu absorbant 11, ayant pour effet une augmentation sensible des surfaces en contact avec le milieu absorbant 11 et le combustible en phase liquide.In the embodiment shown in Figures 3 and 4, in which the same elements are designated by the same references as above, a central and axial channel extends over the entire length L1 of the
Grâce à la présence de ce canal central d'absorption 17, la vitesse d'absorption du combustible en phase liquide est de l'ordre de 35 cm³ par min. Comme montré au dessin, l'extrémité 13a du tube de soutirage 13 est disposée sensiblement dans le plan de la face supérieure du matériau absorbant 11.Thanks to the presence of this
L'avantage de cette seconde solution par rapport à la première est que, lorsque le réservoir est manipulé de sa position renversée à sa position droite, le combustible en phase liquide qui a été libéré par le milieu absorbant 11 est réabsorbé beaucoup plus rapidement par celui-ci.The advantage of this second solution compared to the first is that, when the tank is manipulated from its inverted position to its upright position, the fuel in the liquid phase which has been released by the
Le réservoir représenté à la figure 5 est une variante du réservoir de figure 1, dans lequel les mêmes éléments sont désignés par les mêmes références. Dans ce réservoir, la face supérieure 14 du matériau absorbant 11 n'est pas plane mais est constituée par une surface conique dont le sommet est tourné du côté du fond inférieur 3 du réservoir, ce qui permet une augmentation de la longueur du tube 13. Un tel agencement pourrait également s'appliquer au matériau absorbant 11 représenté aux figures 3 et 4.The reservoir shown in FIG. 5 is a variant of the reservoir in FIG. 1, in which the same elements are designated by the same references. In this tank, the
Dans les trois exemples illustrés sur le dessin, l'extrémité libre 13a du tube de soutirage 13 est représenté comme l'extrémité ouverte d'un tube cylindrique normal. Bien entendu il est possible que cette extrémité libre ouverte 13a soit conformée de façon différente, par exemple par ménagement d'une ouverture constituée par une fente longitudinale aménagée le long de l'une des génératrices du tube à partir de l'extrémité de celui-ci.In the three examples illustrated in the drawing, the
