Description

Domaine techniqueTechnical area

La présente invention concerne un dispositif de libération rapide d'au moins deux fluides ainsi qu'un conteneur de transport sécurisé de valeurs comportant un tel dispositif pour effectuer le maculage desdites valeurs lors de l'effraction ou tentative d'effraction dudit conteneur.The present invention relates to a device for the rapid release of at least two fluids and a secure transport container of values comprising such a device for smearing said values during the break-in or attempted break-in of said container.

Technique antérieurePrior art

Dans le domaine des dispositifs de libération de fluide, on connaît un certain nombre de systèmes comportant une chambre en forme générale de tube contenant le fluide et un piston apte à coulisser à l'intérieur de ladite chambre de manière à libérer le fluide par un orifice situé dans la chambre du côté opposé au piston. L'une des principales différences entre ces systèmes est la méthode mise en œuvre pour faire coulisser ledit piston. En effet, la mise en mouvement du piston peut être manuelle, hydraulique, aéraulique ou mécanique. Les principaux inconvénients de ces dispositifs antérieurs sont les difficultés de fabrication et de mise en œuvre, ainsi que leur encombrement relatif.In the field of fluid release devices, a number of systems are known comprising a generally tube-shaped chamber containing the fluid and a piston slidable within said chamber so as to release the fluid through an orifice located in the chamber opposite the piston. One of the main differences between these systems is the method used to slide said piston. Indeed, the setting in motion of the piston can be manual, hydraulic, aeraulic or mechanical. The main disadvantages of these prior devices are the difficulties of manufacture and implementation, as well as their relative size.

A cet égard, le brevet EP 1 560 994 divulgue un système de libération de fluide comprenant un réservoir tubulaire ayant une sortie et contenant du fluide, un piston coulissant de manière sensiblement étanche au fluide à l'intérieur dudit réservoir et un moyen d'alimentation en gaz sous pression du réservoir, de sorte que le piston est poussé vers ladite sortie et que le fluide est éjecté par la sortie. Le système comporte également un verrou activé électroniquement destiné à ouvrir ou fermer ledit moyen d'alimentation. Ce dispositif, appliqué au fluide de marquage des valeurs contenues dans un conteneur de transport sécurisé, lors de l'effraction ou tentative d'effraction dudit conteneur, est difficile à mettre en œuvre et est particulièrement encombrant du fait du volume et de l'externalité de la réserve de gaz.In this respect, the patent EP 1 560 994 discloses a fluid delivery system comprising a tubular reservoir having an outlet and containing fluid, a substantially fluid tight sliding piston within said reservoir and a means for supplying pressurized gas to the reservoir, so that the piston is pushed towards said outlet and the fluid is ejected through the outlet. The system also includes an electronically activated lock for opening or closing said supply means. This device, applied to the marking fluid values contained in a secure transport container, during the break-in or attempted break-in of said container, is difficult to implement and is particularly cumbersome because of the volume and externality of the gas reserve.

On connaît par ailleurs des dispositifs plus compacts, tels que ceux divulgués dans les brevets FR 2 846 698 ou EP 1 462 021 , qui recourent à des générateurs de gaz comprimé de type chimique ou pyrotechnique. Toutefois, ces dispositifs ont été conçus de sorte que leur réutilisation et/ou leur rechargement n'est pas envisageable sans remplacement d'un nombre élevé de composants du dispositif, notamment du réservoir de fluide et du piston dans le cas du brevet FR 2 846 698 .In addition, more compact devices are known, such as those disclosed in the patents. FR 2,846,698 or EP 1 462 021 , which use compressed gas generators of the chemical or pyrotechnic type. However, these devices have been designed so that their reuse and / or reloading is not possible without replacing a large number of components of the device, in particular the fluid reservoir and the piston in the case of the patent. FR 2,846,698 .

Enfin, avec ces différents dispositifs, il faut disposer deux dispositifs en parallèle pour libérer deux fluides, ce qui rend cette disposition particulièrement encombrante et plus onéreuse.Finally, with these different devices, it is necessary to have two devices in parallel to release two fluids, which makes this arrangement particularly cumbersome and more expensive.

Exposé de l'inventionPresentation of the invention

Le but de la présente invention est donc de pallier les inconvénients précédemment cités et de proposer un dispositif de libération rapide d'au moins deux fluides qui soit à la fois compact, rechargeable et réutilisable, avec un minimum de consommables, tout en étant particulièrement simple à réaliser et à mettre en œuvre.The object of the present invention is therefore to overcome the aforementioned drawbacks and to propose a device for the rapid release of at least two fluids which is at the same time compact, refillable and reusable, with a minimum of consumables, while being particularly simple to realize and to implement.

A cet effet, la présente invention a pour objet un dispositif de libération rapide comportant un réservoir tubulaire contenant un premier fluide et au moins un deuxième fluide à libérer et fermé à ses extrémités par un premier flasque et un deuxième flasque muni d'un orifice de sortie et de moyens d'obturation dudit orifice de sortie conditionnant la libération des premier et deuxième fluides, un premier piston coulissant de manière étanche à l'intérieur et le long de l'axe longitudinal dudit réservoir, et des moyens de propulsion et aptes à mettre en mouvement ledit premier piston afin de libérer les premier et deuxième fluides par ledit orifice de sortie, ledit dispositif étant remarquable en ce qu'il comporte au moins un deuxième piston disposé en aval dudit premier piston, coulissant de manière étanche à l'intérieur et le long de l'axe longitudinal dudit réservoir et muni d'un orifice de transfert et de moyens d'obturation dudit orifice de transfert autorisant le passage conditionné du premier fluide, les premier et deuxième pistons séparant le réservoir au moins en une chambre amont comprise entre le premier flasque et le premier piston, une première chambre de stockage contenant le premier fluide et comprise entre le premier piston et le deuxième piston, et au moins une deuxième chambre de stockage contenant le deuxième fluide et comprise entre le deuxième piston et le deuxième flasque.For this purpose, the present invention relates to a rapid release device comprising a tubular reservoir containing a first fluid and at least a second fluid to be released and closed at its ends by a first flange and a second flange provided with a outlet and closure means of said outlet orifice conditioning the release of the first and second fluids, a first piston sealingly sliding inside and along the longitudinal axis of said reservoir, and propulsion means and adapted to moving said first piston to release the first and second fluids by said outlet orifice, said device being remarkable in that it comprises at least one second piston disposed downstream of said first piston, sealingly sliding inside and along the longitudinal axis of said reservoir and provided with a transfer orifice and means for closing said transfer orifice allowing the conditioned passage of the first fluid, the first and second pistons separating the reservoir at least in an upstream chamber between the first flange and the first piston, a first chamber of storage containing the first fluid and between the first piston and the second piston, and at least a second storage chamber containing the second fluid and between the second piston and the second flange.

Les moyens d'obturation respectifs de l'orifice de sortie et de l'orifice de transfert sont dimensionnés pour libérer soit simultanément ou soit séquentiellement les premier et deuxième fluides.The respective closure means of the outlet orifice and the transfer orifice are dimensioned to release either simultaneously or sequentially the first and second fluids.

Selon un mode de réalisation préférentiel, les moyens d'obturation de l'orifice de sortie sont un opercule de rupture apte à se déchirer afin de libérer les premier et/ou deuxième fluides lorsque la pression à l'intérieur du réservoir atteint une valeur déterminée.According to a preferred embodiment, the closure means of the outlet orifice are a rupture seal capable of tearing in order to release the first and / or second fluids when the pressure inside the reservoir reaches a predetermined value. .

Selon une variante de réalisation, les moyens d'obturation de l'orifice de sortie sont une vanne commandée ou asservie.According to an alternative embodiment, the closure means of the outlet orifice are a controlled valve or slave.

Selon un mode de réalisation préférentiel, les moyens d'obturation de l'orifice de transfert sont un opercule de rupture apte à se déchirer afin de permettre le passage du premier fluide lorsque la pression à l'intérieur de la première chambre de stockage atteint une valeur déterminée.According to a preferred embodiment, the closure means of the transfer orifice are a rupture seal capable of tearing in order to allow the passage of the first fluid when the pressure inside the first storage chamber reaches a maximum temperature. determined value.

Les moyens de propulsion sont avantageusement un générateur de gaz choisi parmi le groupe chimique, pyrotechnique, hybride ou de type à gaz froids.The propulsion means are advantageously a gas generator chosen from the chemical, pyrotechnic, hybrid or cold gas type group.

De manière avantageuse, les premier et deuxième pistons possèdent respectivement un évidement interne de sorte que leur face de propulsion soit située en amont au moins de la majeure partie des premier et deuxième pistons en contact avec le réservoir.Advantageously, the first and second pistons respectively have an internal recess so that their propulsion face is located upstream of at least most of the first and second pistons in contact with the reservoir.

L'invention concerne également un conteneur de transport sécurisé de valeurs, comportant au moins un dispositif de libération selon l'invention.The invention also relates to a secure transport container of values, comprising at least one release device according to the invention.

Meilleure manière de réaliser l'invention techniqueBest way to realize the technical invention

En référence aux figures 1 à 5, le dispositif 1 de libération d'au moins deux fluides, conforme à l'invention, comprend un réservoir 2 en forme générale de tube, un premier flasque 3 de fermeture en forme générale de disque fixé de manière étanche à l'une des extrémités dudit réservoir 2, un deuxième flasque 4 de fermeture en forme générale de disque fixé de manière étanche à l'autre extrémité dudit réservoir 2 et muni d'un orifice de sortie 41 débouchant des deux côtés et aménagé sensiblement au milieu dudit deuxième flasque 4, et un premier piston 5 et au moins un deuxième piston 6.With reference to Figures 1 to 5 , the device 1 for the release of at least two fluids, according to the invention, comprises a reservoir 2 in the general shape of a tube, a first flange 3 of closure in the general shape of a disk sealingly attached to one of the ends of said reservoir 2, a second flange 4 of generally disk-shaped closure sealingly attached to the other end of said reservoir 2 and provided with an outlet opening 41 opening on both sides and arranged substantially in the middle of said second flange 4, and a first piston 5 and at least a second piston 6.

Les premier et deuxième pistons 5,6 séparent le réservoir 2 au moins en trois parties. La première partie comprise entre le premier flasque 3 et le premier piston 5 est la chambre amont 21, la deuxième partie comprise entre le premier piston 5 et le deuxième piston 6 est la première chambre de stockage 22, et la troisième partie comprise entre le deuxième piston 6 et le deuxième flasque 4 est la deuxième chambre de stockage 23.The first and second pistons 5.6 separate the reservoir 2 at least into three parts. The first part between the first flange 3 and the first piston 5 is the upstream chamber 21, the second part between the first piston 5 and the second piston 6 is the first storage chamber 22, and the third part between the second piston 6 and the second flange 4 is the second storage chamber 23.

Lesdites première et deuxième chambres de stockage 22,23 contiennent respectivement un premier fluide 7 et un deuxième fluide 8.Said first and second storage chambers 22, 23 respectively contain a first fluid 7 and a second fluid 8.

Les premier et deuxième pistons 5,6, qui sont avantageusement du type flottant, c'est-à-dire sans tige de liaison, sont aptes à coulisser, de manière sensiblement étanche auxdits premier et/ou deuxième fluides 7,8, à l'intérieur et le long de l'axe longitudinal dudit réservoir 2. Lesdits premier et deuxième pistons 5,6 coulissent entre une position « stockage » où les première et deuxième chambres de stockage 22,23 sont remplies et une position « travail » où la première chambre de stockage 22 et la deuxième chambre de stockage 23 sont respectivement vides.The first and second pistons 5.6, which are advantageously of the floating type, that is to say without connecting rod, are able to slide, substantially sealingly to said first and / or second fluids 7,8, to the and said first and second pistons 5,6 slide between a "storage" position where the first and second storage chambers 22,23 are filled and a "work" position where the first storage chamber 22 and the second storage chamber 23 are respectively empty.

Avec une telle configuration, on comprend bien que le deuxième piston 6 est disposé en aval dudit premier piston 5.With such a configuration, it is well understood that the second piston 6 is disposed downstream of said first piston 5.

On désigne ici par « aval » et « amont » une position qui succède, respectivement qui précède, une autre dans le sens du déplacement des premier et deuxième pistons 5,6, à savoir depuis leur position « stockage » jusqu'à sa position « travail ».Here "downstream" and "upstream" denotes a position that succeeds, respectively preceding, another one in the direction of movement of the first and second pistons 5,6, namely from their "storage" position to its position " job ".

Le dispositif 1 comporte en outre des moyens de propulsion, non représentés sur les figures, avantageusement solidaires du premier flasque 3 et disposés avantageusement au milieu de ce dernier.The device 1 further comprises propulsion means, not shown in the figures, preferably secured to the first flange 3 and advantageously arranged in the middle thereof.

Dans un mode de réalisation préférentiel, ces moyens de propulsion sont un générateur de gaz apte à libérer dans un laps de temps très court une quantité de gaz suffisante pour mettre en mouvement, à l'intérieur du réservoir 2, les premier et deuxième pistons 5,6 de manière à libérer successivement ou simultanément les premier et deuxième fluides 7,8 au travers de l'orifice de sortie 41.In a preferred embodiment, these propulsion means are a gas generator capable of releasing, within a very short period of time, a quantity of gas sufficient to set the first and second pistons 5 in motion inside the tank 2. , In order to successively or simultaneously release the first and second fluids 7,8 through the outlet orifice 41.

Ledit générateur de gaz est de préférence semblable à ceux utilisés dans les systèmes de coussins gonflables de sécurité pour les automobiles. En outre, ce générateur de gaz est de préférence un générateur pyrotechnique, mais il peut être substitué par tout autre générateur de gaz tel que des générateurs de gaz chimiques, hybrides, de types gaz froid ou analogues ou par tout autre moyen de génération de gaz procurant des effets similaires.Said gas generator is preferably similar to those used in airbag systems for automobiles. In addition, this gas generator is preferably a pyrotechnic generator, but it may be substituted by any other gas generator such as chemical gas generators, hybrid generators, cold gas generators or the like, or by any other means of generating gas. providing similar effects.

Toutefois, sans sortir du cadre de la présente invention, ces moyens de propulsion pourront être d'un tout autre type tel que, par exemple, une tige reliée à un actionneur et apte à mettre en mouvement le premier piston 5.However, without departing from the scope of the present invention, these propulsion means may be of a completely different type such as, for example, a rod connected to an actuator and adapted to set in motion the first piston 5.

Par ailleurs, l'Homme du Métier n'aura aucune difficulté à dimensionner le générateur de gaz en fonction notamment des caractéristiques suivantes :

  • le volume des premier et deuxième fluides 7,8 à libérer et leur durée de libération,
  • la vitesse de propulsion des premier et deuxième pistons 5,6.
Moreover, the skilled person will have no difficulty in sizing the gas generator based in particular on the following characteristics:
  • the volume of the first and second fluids 7,8 to be released and their duration of release,
  • the propulsion speed of the first and second pistons 5,6.

En référence à la figure 4, le deuxième flasque 4 présente sensiblement en son milieu un orifice 42 de préférence cylindrique dont le diamètre intérieur est supérieur au diamètre de l'orifice de sortie 41 et débouchant d'un côté à l'extérieur du réservoir 2 et de l'autre côté dans ledit orifice de sortie 41. La partie interne de cet orifice 42 possède une première partie femelle 421.With reference to the figure 4 , the second flange 4 has substantially in its middle a preferably cylindrical orifice 42 whose inside diameter is greater than the diameter of the outlet orifice 41 and opening on one side outside the tank 2 and on the other side in said outlet port 41. The inner portion of this port 42 has a first female portion 421.

Le dispositif 1 comporte un élément tubulaire 9 indépendant, avantageusement de forme globalement cylindrique et comprenant une partie mâle 91 apte à coopérer avec ladite partie femelle 421 de l'orifice 42 de sorte à fixer de manière étanche et non permanente l'élément tubulaire 9 dans le deuxième flasque 4.The device 1 comprises a tubular element 9 independent, advantageously of generally cylindrical shape and comprising a male portion 91 adapted to cooperate with said female portion 421 of the orifice 42 so as to fix tightly and non-permanently the tubular element 9 in the second flange 4.

Pour des raisons économiques évidentes, les parties mâle et femelle 421, 91 sont avantageusement et respectivement un taraudage et un filetage.For obvious economic reasons, the male and female parts 421, 91 are advantageously and respectively a thread and a thread.

La partie interne dudit élément tubulaire 9 est apte à coopérer avec l'extrémité d'une tuyauterie de façon à permettre, par exemple, d'acheminer les premier et deuxième fluides 7,8 à un endroit bien défini.The inner portion of said tubular element 9 is adapted to cooperate with the end of a pipe so as to allow, for example, to route the first and second fluids 7,8 at a well-defined location.

L'élément tubulaire 9 comporte à l'une de ses extrémités un rebord périphérique 92 permettant de limiter la course de déplacement dudit élément tubulaire 9 dans l'orifice 42 en mettant en contact ledit rebord 92 avec le deuxième flasque 4.The tubular element 9 comprises at one of its ends a peripheral rim 92 making it possible to limit the displacement stroke of said tubular element 9 in the orifice 42 by bringing said flange 92 into contact with the second flange 4.

De plus, le deuxième flasque 4 du dispositif 1 comporte des moyens d'obturation de l'orifice de sortie 41 aptes à n'autoriser la libération d'au moins le deuxième fluide 8 que sous conditions telles que, par exemple, lorsque la pression à l'intérieur de la deuxième chambre de stockage 23 du réservoir 2 atteint une valeur déterminée.In addition, the second flange 4 of the device 1 comprises closure means of the outlet orifice 41 able to allow the release of at least the second fluid 8 only under conditions such as, for example, when the pressure inside the second storage chamber 23 of the tank 2 reaches a determined value.

En référence à la figure 4, selon un mode de réalisation préférentiel, ces moyens d'obturation sont un opercule 10 de rupture. Cet opercule 10 permet d'obturer le réservoir 2 et de maintenir les premier et deuxième fluides 7,8 à l'intérieur dudit réservoir 2 quand les premier et deuxième pistons 5,6 sont en position « stockage », et est apte à se déchirer afin de libérer les premier et/ou deuxième fluides 7,8 lorsque les premier et/ou deuxième pistons 5,6 commencent à coulisser et que la pression à l'intérieur du réservoir 2 augmente et atteint une valeur déterminée. Pour cela, ledit opercule 10 sera avantageusement réalisé en aluminium de faible épaisseur, par exemple 0,1 mm, ou encore en élastomère, saturé ou non, avec un point de rupture.With reference to the figure 4 , according to a preferred embodiment, these sealing means are a rupture cap. This cap 10 makes it possible to close the reservoir 2 and to keep the first and second fluids 7.8 inside said reservoir 2 when the first and second pistons 5, 6 are in the "storage" position, and is capable of tearing in order to release the first and / or second fluids 7,8 when the first and / or second pistons 5,6 begin to slide and the pressure inside the tank 2 increases and reaches a determined value. For this, said lid 10 will advantageously be made of thin aluminum, for example 0.1 mm, or elastomer, saturated or not, with a breaking point.

De plus, pour maintenir en position l'opercule 10 de rupture, l'élément tubulaire 9 est dimensionné de sorte que, lorsque son rebord 92 est en contact avec le deuxième flasque 4, ledit opercule 10 est maintenu de façon étanche par l'élément tubulaire 9 à l'intérieur de l'orifice 42 du deuxième flasque 4.In addition, in order to maintain the rupture cap 10 in position, the tubular element 9 is dimensioned so that, when its flange 92 is in contact with the second flange 4, said cap 10 is held tightly by the element tubular 9 inside the orifice 42 of the second flange 4.

Les moyens d'obturation de l'orifice de sortie 41 pourrait être d'un tout autre type, tel que par exemple une vanne commandée ou asservie, sans sortir du cadre de la présente invention.The closure means of the outlet orifice 41 could be of a completely different type, such as for example a controlled or controlled valve, without departing from the scope of the present invention.

En référence à la figure 5, le deuxième piston 6 comporte un orifice de transfert 61 permettant le passage du premier fluide 7 de la première chambre de stockage 22 à la deuxième chambre de stockage 23 et des moyens d'obturation dudit orifice de transfert 61 aptes à n'autoriser la libération du premier fluide 7 contenu dans la première chambre de stockage 22 du réservoir 2 que sous conditions telles que, par exemple, lorsque la pression à l'intérieur de ladite première chambre de stockage 22 atteint une valeur déterminée.With reference to the figure 5 the second piston 6 comprises a transfer orifice 61 allowing the first fluid 7 to pass from the first storage chamber 22 to the second storage chamber 23 and means for closing off said transfer orifice 61 able to authorize the release the first fluid 7 contained in the first storage chamber 22 of the tank 2 only under conditions such as, for example, when the pressure inside said first storage chamber 22 reaches a predetermined value.

Selon un mode de réalisation préférentiel analogue à celui des moyens d'obturation de l'orifice de sortie 41 du deuxième flasque 4 précédemment décrits, ces moyens d'obturation sont un opercule 11 de rupture. Cet opercule 11 du deuxième piston 6 permet d'obturer la première chambre de stockage 22 du réservoir 2 et de maintenir le premier fluide 7 à l'intérieur de cette dernière et est apte à se déchirer afin de libérer le premier fluide 7 lorsque la pression à l'intérieur de ladite première chambre de stockage 22 augmente. Pour cela, ledit opercule 11 sera avantageusement réalisé en aluminium de faible épaisseur, par exemple 0,1 mm, ou encore en élastomère avec un point de rupture.According to a preferred embodiment similar to that of the closure means of the outlet orifice 41 of the second flange 4 described above, these sealing means are a rupture cap 11. This seal 11 of the second piston 6 closes the first storage chamber 22 of the reservoir 2 and maintains the first fluid 7 inside the latter and is able to tear in order to release the first fluid 7 when the pressure within said first storage chamber 22 increases. For this, said seal 11 will advantageously be made of thin aluminum, for example 0.1 mm, or elastomer with a point of break.

De même, l'opercule 11 de rupture est maintenu de façon étanche par un élément tubulaire 12 solidaire du deuxième piston 6, de manière étanche et non permanente.Similarly, the rupture seal 11 is held tightly by a tubular element 12 integral with the second piston 6, in a sealed and non-permanent manner.

Les moyens d'obturation respectifs de l'orifice de sortie 41 et de l'orifice de transfert 61 sont dimensionnés pour libérer soit simultanément ou soit successivement les premier et deuxième fluides 7,8. Ainsi, en fonction de l'utilisation du dispositif 1, on pourra soit libérer le deuxième fluide 8 puis le premier fluide 7, si on ne souhaite pas mélanger les premier et deuxième fluides 7,8, soit libérer d'abord le premier fluide 7 dans la deuxième chambre de stockage 23 afin que ce dernier se mélange avec le deuxième fluide 8, puis libérer le mélange obtenu à l'extérieur du réservoir 2.The respective closure means of the outlet orifice 41 and the transfer orifice 61 are dimensioned to release either simultaneously or successively the first and second fluids 7,8. Thus, depending on the use of the device 1, it will be possible to release the second fluid 8 and then the first fluid 7, if it is not desired to mix the first and second fluids 7, 8 or first to release the first fluid 7 in the second storage chamber 23 so that the latter mixes with the second fluid 8, then release the mixture obtained outside the tank 2.

Compte tenu de ce qui précède, on comprend bien que le dispositif 1 est facilement réutilisable, après la déchirure des opercules 10,11 respectifs du deuxième flasque 4 et du deuxième piston 6 suivie de la libération totale des premier et deuxième fluides 7,8. Pour cela, il suffit de remplacer, d'une part, lesdits opercules 10,11 en démontant les éléments tubulaires 9,12 associés et, d'autre part, le générateur de gaz qui est avantageusement fixé de façon étanche et non permanente sur le premier flasque 3.In view of the above, it is clear that the device 1 is easily reusable, after the tearing of the respective lids 10,11 of the second flange 4 and the second piston 6 followed by the total release of the first and second fluids 7,8. For this, it suffices to replace, on the one hand, said lids 10,11 by dismounting the associated tubular elements 9,12 and, on the other hand, the gas generator which is advantageously fixed in a sealed and non-permanent manner on the first flange 3.

De manière classique, les premier et deuxième pistons 5,6 sont en forme globale de cylindre aplati plein. Toutefois, chacun des premier et deuxième pistons 5,6 pourra avoir une toute autre forme sans sortir du cadre de la présente invention.In a conventional manner, the first and second pistons 5, 6 are in the form of a flattened full cylinder. However, each of the first and second pistons 5,6 may have a different shape without departing from the scope of the present invention.

Ainsi, en référence aux figures 3 et 4,selon un mode de réalisation préférentiel, compte tenu des caractéristiques dynamiques du dispositif 1, les premier et deuxième pistons 5,6 possèdent respectivement un évidement interne 51,62 de sorte que leur face de propulsion 52,63, qui est respectivement du côté des moyens de propulsion et en contact avec le premier fluide 7, soit située en amont au moins de la majeure partie des premier et deuxième pistons 5,6 en contact avec le réservoir 2. Ainsi, dans cette configuration, lesdits gaz exercent sur ladite face de propulsion une force qui peut être assimilée à une force de traction et non pas une force de poussée limitant ainsi les risques d'arc-boutement des premier et deuxième pistons 5,6 à l'intérieur du réservoir 2.Thus, with reference to Figures 3 and 4 , according to a preferred embodiment, taking into account the dynamic characteristics of the device 1, the first and second pistons 5,6 respectively have an internal recess 51,62 so that their propulsion face 52,63, which is respectively on the side of the propulsion means and in contact with the first fluid 7, is located upstream at least of the major part of the first and second pistons 5,6 in contact with the reservoir 2. Thus, in this configuration, said gases exert on said propulsion surface a force which can be likened to a traction force and not a thrust force thus limiting the risk of jamming of the first and second pistons 5,6 inside the tank 2.

Par ailleurs, les premier et deuxième pistons 5,6 sont de préférence munis respectivement d'au moins une gorge périphérique 53,64 apte à accueillir un organe d'étanchéité, non représenté sur les figures, de sorte à assurer leur étanchéité statique ou dynamique au premier et/ou deuxième fluides 7,8 contenus dans les première et/ou deuxième chambre de stockage 22,23 du réservoir 2. Pour des raisons économiques et de simplicité, ledit organe d'étanchéité est de préférence un joint torique.Furthermore, the first and second pistons 5.6 are preferably respectively provided with at least one peripheral groove 53, 64 adapted to receive a sealing member, not shown in the figures, so as to ensure their static or dynamic sealing. to the first and / or second fluids 7,8 contained in the first and / or second storage chamber 22,23 of the tank 2. For reasons of economy and simplicity, said sealing member is preferably an O-ring.

De même, selon un mode de réalisation préférentiel, les premier et deuxième flasque 3,4 possèdent une gorge 43 périphérique apte à recevoir un organe d'étanchéité, non représenté sur les figures, qui est de préférence un joint torique.Similarly, according to a preferred embodiment, the first and second flange 3,4 have a peripheral groove 43 adapted to receive a sealing member, not shown in the figures, which is preferably an O-ring.

Compte tenu de ce qui précède, le réservoir 2 et les premier et deuxième flasques 3,4 sont avantageusement métalliques. Pour des raisons de limitation de poids, ils sont réalisés à partir d'un alliage léger ; de préférence il s'agit d'un alliage d'aluminium.In view of the foregoing, the tank 2 and the first and second flanges 3,4 are advantageously metallic. For reasons of weight limitation, they are made from a light alloy; preferably it is an aluminum alloy.

L'Homme du Métier n'aura aucune difficulté à concevoir d'une autre manière les différents assemblages étanches, en remplaçant par exemple les différents organes d'étanchéité par tout autre moyen d'étanchéité procurant des effets similaires comme par exemple du mastic ou des joints à lèvres, sans sortir du cadre de la présente invention.Those skilled in the art will have no difficulty in designing the different waterproof assemblies in another way, for example by replacing the various sealing members with any other sealing means providing similar effects, for example mastic or lip seals, without departing from the scope of the present invention.

De même, afin de résister aux contraintes mécaniques générées notamment par la réaction pyrotechnique, l'Homme du Métier n'aura aucune difficulté à dimensionner les éléments constitutifs du dispositif 1 et notamment leur épaisseur.Similarly, in order to withstand the mechanical stresses generated in particular by the pyrotechnic reaction, the skilled person will have no difficulty in sizing the constituent elements of the device 1 and in particular their thickness.

Enfin, il va de soi que les matériaux employés pour réaliser les éléments constitutifs du dispositif 1 doivent être compatibles avec les premier et deuxième fluides 7,8 contenus dans le réservoir 2, notamment être chimiquement inertes vis-à-vis desdits fluides.Finally, it goes without saying that the materials used to produce the constituent elements of the device 1 must be compatible with the first and second fluids 7.8 contained in the reservoir 2, in particular be chemically inert vis-à-vis said fluids.

On comprend bien que le dispositif 1 est particulièrement intéressant car il est de conception simple et permet, dans un encombrement réduit, de stocker et de libérer simultanément ou successivement au moins deux fluides compatibles chimiquement ou non.It is understood that the device 1 is particularly interesting because it is simple in design and allows, in a small footprint, to store and release simultaneously or successively at least two fluids chemically compatible or not.

Enfin, on comprend bien que le dispositif 1 selon l'invention peut comporter plusieurs deuxièmes pistons 6 disposés les uns à la suite des autres, en aval du premier piston 5, de sorte à créer dans le réservoir 2 une troisième, une quatrième, ... etc. chambres de stockages contenant respectivement un troisième, un quatrième, ... etc. fluide.Finally, it is well understood that the device 1 according to the invention may comprise a plurality of second pistons 6 arranged one after the other, downstream of the first piston 5, so as to create in the reservoir 2 a third, a fourth. .. etc. storage rooms containing respectively a third, a fourth, ... etc. fluid.

Un deuxième objet de la présente invention est un conteneur de transport et/ou de stockage sécurisé de valeurs mettant en œuvre un dispositif 1 de libération rapide de fluide permettant pour le maculage desdites valeurs, lors de l'effraction ou tentative d'effraction dudit conteneur.A second object of the present invention is a container for transport and / or secure storage of securities implementing a device 1 for rapid fluid release for smearing said values, during the break-in or attempted break-in of said container .

En effet, avec le développement des billets de banque polymères, le besoin d'ajouter un deuxième composant favorisant l'accroche d'un liquide d'altération tel que, par exemple, de l'encre de maculage indélébile, sur lesdits billets polymères est apparu. Toutefois, ce deuxième composant peut avoir un impact négatif au contact de l'encre. Il est donc primordial de pouvoir stocker l'encre et ledit deuxième composant indépendamment et de pouvoir libérer les deux fluides de façon successive et/ou séquentielle.Indeed, with the development of polymeric banknotes, the need to add a second component promoting the attachment of an alteration liquid such as, for example, indelible smearing ink, on said polymer banknotes is appeared. However, this second component can have a negative impact on contact with the ink. It is therefore essential to be able to store the ink and said second component independently and to be able to release the two fluids successively and / or sequentially.

Dans cette application, le dispositif 1 est disposé à l'intérieur dudit conteneur de transport à côté du compartiment de stockage des valeurs et est relié par l'élément tubulaire 9 à un dispositif d'aspersion, par exemple une rampe, permettant de maculer lesdites valeurs.In this application, the device 1 is disposed inside said transport container next to the value storage compartment and is connected by the tubular element 9 to a spraying device, for example a ramp, for staining said values.

Les premier et deuxième fluides 7,8 sont de préférence choisis parmi le groupe non limitatif de couples de matériaux suivant :

  • colle, gel ou mastic + primaire,
  • colle, gel ou mastic + activateur,
  • liquide agressif + colorant indélébile,
  • liquide agressif ou colorant indélébile + primaire,
  • liquide agressif ou colorant indélébile + traceur chimique,
  • liquide agressif ou colorant indélébile + gaz odorant ou inerte,
  • polyol + traceur chimique + isocyanate.
The first and second fluids 7,8 are preferably chosen from the following nonlimiting group of material pairs:
  • glue, gel or putty + primer,
  • glue, gel or mastic + activator,
  • aggressive liquid + indelible dye,
  • aggressive liquid or indelible + primary dye,
  • aggressive liquid or indelible dye + chemical tracer,
  • aggressive liquid or indelible dye + odorous or inert gas,
  • polyol + chemical tracer + isocyanate.

L'utilisation d'un traceur chimique permet de relier à un vol ou une agression donnée des valeurs maculées retrouvées postérieurement.The use of a chemical tracer makes it possible to connect to a given flight or aggression stained values found later.

Ainsi, lors de l'effraction ou tentative d'effraction dudit conteneur, le générateur de gaz se déclenche, propulse le piston 8 et libère les premier et deuxième fluides 7,8 à travers l'orifice 41, l'élément tubulaire 9 et le dispositif d'aspersion pour marquer de façon permanente les valeurs.Thus, during the burglary or attempted break-in of said container, the gas generator is triggered, propels the piston 8 and releases the first and second fluids 7,8 through the orifice 41, the tubular element 9 and the spraying device to permanently mark the values.

Possibilités d'application industriellePossibilities of industrial application

Le dispositif de soufflage 1 selon l'invention s'applique plus particulièrement aux conteneurs de transport sécurisé de valeurs, mais il peut également être utilisé dans d'autres domaines tels que, par exemple, les seringues utilisées dans le milieu médical, la protection incendie ou encore des milieux où la manipulation est difficile ou périlleuse (milieu sous-marin, ...).The blowing device 1 according to the invention applies more particularly to safe transport containers of values, but it can also be used in other fields such as, for example, syringes used in the medical environment, fire protection or else environments where handling is difficult or perilous (underwater environment, ...).

Enfin, il va bien entendu de soi que la présente invention n'est pas limitée à l'exemple de réalisation préférentiel et à la mise en œuvre décrits, mais qu'elle peut être modifiée ou adaptée en fonction des besoins ou des exigences particulières, sans pour autant sortir du cadre de l'invention.Finally, it goes without saying that the present invention is not limited to the preferred embodiment and implementation described, but that it can be modified or adapted according to the needs or special requirements, without departing from the scope of the invention.
