Abstract

The reservoir or pressure vessel (1) is constructed in three sections (5,6). Each section is fabricated from two halves and the separate sections are welded together to form a vessel with a lenticular shape. This form is suitable for L.P.G. storage below the boot of a gas powered automobile. The vessel has a safety bolt (15) passing through it having a reduced cross section (16). The bolt is designed to fail if the internal pressure reaches a predetermined level. This will allow the vessel to deform, toward a spherical shape and prevent a rupture.

Description

L'invention se rapporte a un réservoir relativement plat
destiné à contenir un fluide sous pression et plus particu
lièrement mais non exclusivement du gaz de pétrole liquéfié.The invention relates to a relatively flat tank
intended to contain a fluid under pressure and more particu
but not exclusively liquefied petroleum gas.

La consommetion des gaz de pétrole liquéfiés que sont le
butane et le propane ne cesse de croître du fait de leur
qualité de combustibles propres, d'utilisation aisée et
assez économiques
Ces gaz de pétrole liquéfiés sont largement distribues en
bouteilles, mais c'est la vente en vrac qui sé développe le
plus rapidement.The consumption of liquefied petroleum gases which are the
butane and propane keeps growing because of their
quality of clean fuels, easy to use and
fairly economical
These liquefied petroleum gases are widely distributed in
bottles, but it is the bulk sale that is developing the
faster.

Une application intéressante de ces gaz est l'alimenta
tion des moteurs de véhicules automobiles et d'ailleurs,
depuis un certain temps, on peut rencontrer des véhicules
fonctionnant ainsi.An interesting application of these gases is the food
tion of motor vehicle engines and elsewhere,
for some time we can meet vehicles
thus functioning.

Sur ces véhicules, le gaz est préleve dans une bouteille par exemple > ue vingt cinq litres du type adopté dans les foyers domes
tiques pour la cuisson des aliments et le chauffage d'ap-
point et qui, pour les besoins de la cause, est logée dans
le coffre du véhicule.En effet, son encombrement est tel
que cette bouteille ne peut trouver place sous le coffre à
la manière d'un réservoir à essence,
La demande de tels véhicules est malheureusement freinée
par les inconvénients que représentent, d'une part, leinsta-
bilité de cette bouteille, ce à quoi il peut toutefois etre
remeQie, mais surtout, d'autre part, la place importante qui
est nécessaire à cette bouteille qui vient donc encombrer le
coffre.On these vehicles, the gas is taken in a bottle for example> twenty five liters of the type adopted in domes households
ticks for cooking food and heating
point and which, for the needs of the cause, is housed in
the trunk of the vehicle because its size is such
that this bottle cannot find place under the trunk
the way of a petrol tank,
The demand for such vehicles is unfortunately curbed
by the disadvantages which, on the one hand, represent
bility of this bottle, what it can however be
remeQie, but above all, on the other hand, the important place which
is necessary for this bottle which therefore clogs the
chest.

Au point de vue résistance, la forme idéale pour un réserve
voir de fluide sous pression est shérique afin d'équilibrer
les contraintes mais une telie forme pose les mimes problè
mes d'encombrement que la bouteille ci-dessus.In terms of resistance, the ideal form for a reserve
see pressurized fluid is sheric in order to balance
constraints but such a form poses the same problems
dimensions of the bottle above.

Des recherches ont donc été faites pour parvenir å stocker
lc gaz dans un volume relativementplat pour, a' la manière
d'un réservoir d'essence, etre facilement logé contre une
paroi et par exemple sous le plancher du coffre.Research has therefore been done to achieve storage
lc gas in a relatively flat volume for, in the way
of a petrol tank, be easily accommodated against a
wall and for example under the trunk floor.

La solution d'un réservoir classique, par exemple sensible
meot parallélépipèdique, a aussitôt été écartée car même à
pression normale, le gaz de pétrole liquéfié bomberait
aussitôt les faces de ce réservoir qui tendrait ainsi à prendre une forme plus proche d'une sphère dépassant la hauteur admissible.The solution of a conventional, for example sensitive tank
meot parallelepiped, was immediately discarded because even at
normal pressure, liquefied petroleum gas would boom
immediately the faces of this tank which would tend to take a shape closer to a sphere exceeding the admissible height.

L'idée de raidir les faces d'un tel réservoir par des nervures a également dû être écartée car perpendiculairement au raidissage obtenu dans le sens des nervures, la face s'allon- ge et se déforme encore plus facilement. The idea of stiffening the faces of such a reservoir by ribs also had to be discarded because perpendicular to the stiffening obtained in the direction of the ribs, the face lengthens and deforms even more easily.

De ce fait, une solution tenue à ce jour, consiste à réali ser une réserve formée de plusieurs bouteilles de diamètres
et correspondant sensiblement à la hauteur maximale fixée ffi i sont alors placés cote à cote. Cette niultiplication de bouteilles conduit à un ensemble lourd et complique fortement les problèmes de raccordement à la conduite d'alimentation du moteur.Therefore, a solution kept to this day, consists in realizing a reserve formed of several bottles of diameters
and corresponding substantially to the maximum fixed height ffi i are then placed side by side. This multiplication of bottles leads to a heavy assembly and greatly complicates the problems of connection to the engine supply line.

Découlant de leur indéformabilité, un autre inconvénient présenté par tous les réservoirs connus a ce jour est qu'ils n'coffrent pas de réserve d'expansion en cas de surpression, suite à une utilisation dans des conditions anormales. Arising from their non-deformability, another drawback presented by all the tanks known to date is that they do not offer an expansion reserve in the event of overpressure, following use under abnormal conditions.

Ils risquent donc rapidement d'exploser à moins d'augmenter fortement les épaisseurs des parois et/ou les volumes, ce qui majorerait encore lfencombrement et le poids de la réserve. They therefore risk rapidly exploding unless the wall thicknesses and / or volumes are greatly increased, which would further increase the size and weight of the reserve.

Un résultat que l'invention vise à obtenir est un réservoir relativement plat indéformable aux pressions normales de fluides tels que le gaz de pétrole liquéfié et offrant une réserve d'expansion en cas de surpression accidentelle
A cet effet, elle a pour objet, un réservoir du type cité plus haut, notamment caractérisé en ce qu'il comprend deux parois principales opposées qui ne sont que très faiblement distantes l'une de l'autre et qui sont reliées entre elles par au moins une entretoise dont la section la plus faible a une valeur calibrée, afin que cette entretoise acquiert un point de rupture pidéterminé. A result which the invention aims to obtain is a relatively flat tank which is non-deformable at normal pressures of fluids such as liquefied petroleum gas and which offers an expansion reserve in the event of accidental overpressure.
To this end, it has for its object a reservoir of the type mentioned above, in particular characterized in that it comprises two opposite main walls which are only very slightly distant from each other and which are connected together by at least one spacer of which the smallest section has a calibrated value, so that this spacer acquires a pidetermined breaking point.

L'invetion sera bien comprise à l'aide de la description ci-après faite, à titre d'exemple non limitatif, en regard du dessin ci-annexé qui représente scHématiquement
- figure 1 : le réservoir vu de dessus
- figure 2 : une coupe selon II II de la figure 1
- figure 3 : le réservoir vu de profil.The invention will be clearly understood with the aid of the description below, given by way of nonlimiting example, with reference to the appended drawing which represents schematically
- Figure 1: the tank seen from above
- Figure 2: a section along II II of Figure 1
- Figure 3: the tank seen in profile.

pn se reportant au dessin, on remarque que le réservoir 1 a une forme générale relativement plate.  pn referring to the drawing, it is noted that the reservoir 1 has a relatively flat general shape.

De face (figure 2) et de profil (figure 3), ce réservoir a une section sensiblement ovale très allongée.From the front (Figure 2) and in profile (Figure 3), this tank has a substantially elongated, substantially oval section.

En vue de dessus, on remarque que le réservoir 1 a une forme non angulaire et par exemple circulaire ou ovale ou elliptique ou formée par une telle surface- scindée en deux parties égales raccordées sur les côtés opposés d'une partie centrale carrée ou rectangulaire, comme cela est représenté au dessin ci-annexé. When viewed from above, it can be seen that the reservoir 1 has a non-angular shape and for example circular or oval or elliptical or formed by such a surface divided into two equal parts connected on the opposite sides of a central square or rectangular part, as shown in the accompanying drawing.

Dans cet exemple, le réservoir est réalisé par emboutissage puis assemblage par soudure, d'une partie centrale 2 en deux demi viroles ovales 3,4, et de deux extrémités 5,6 formés chacune par assemblage de deux demi fonds 7,8 ou 9,10. In this example, the reservoir is produced by stamping and then assembly by welding, of a central part 2 into two oval half-ferrules 3,4, and of two ends 5,6 each formed by assembling two half-bottoms 7,8 or 9 , 10.

Du fait de sa section ovale très allongée, ce réservoir 1 ne comprend donc pratiquement que deux parois principales opposées 11,12, régulièrement bombées vers l'extérieur et dont la majeure partie de ces parois principales 11,12 n'est d'ailleurs que faiblement bombée, afin que la distance "D qui les se- pare en leur centre, demeure suffisamment faible pour que le réservoir trouve facilement place sur le c8té ou au-dessous d'un coffre de véhicule automobile. Due to its very elongated oval section, this reservoir 1 therefore practically only comprises two opposite main walls 11,12, regularly curved outwards and the major part of these main walls 11,12 of which is only slightly curved, so that the distance "D which separates them at their center, remains sufficiently small so that the tank can easily be placed on the side or below a trunk of a motor vehicle.

En leur centre, chacune des parois principales reçoit une plaque de renforcement 13,14. At their center, each of the main walls receives a reinforcing plate 13,14.

Selon une caractéristique essentielle de l'invention, entre leur partie centrale, les parois principales sont reliées par une entretoise 13 dont la section 16 la plus faible a une valeur calibrée, afin que cette entretoise acquiert un point de rupture prédéterminé. According to an essential characteristic of the invention, between their central part, the main walls are connected by a spacer 13 of which the smallest section 16 has a calibrated value, so that this spacer acquires a predetermined breaking point.

Par exemple, si le réservoir est appelé à travailler normalement sous une pression de vingt bars, la section pourra être prédéterminée pour que la rupture de l'entretoise ait lieu à partir d'une pression relativement plus élevée, par exemple de trente bars et consécutive à une anomalie. For example, if the reservoir is called upon to work normally under a pressure of twenty bars, the cross section can be predetermined so that the rupture of the spacer takes place from a relatively higher pressure, for example thirty bars and consecutive to an anomaly.

Par cette rupture de l'entretoise 13, le réservoir jusqu' alors très plat peut, sous la pression, se déformer et tendre vers une forme de plus mande capacité et plus sphérique et donc apte à résister jusqu'à une très forte pression par exemple de soixante bars, sans courir le risque d'une explosion,
Chaque paroi principale 11,12 et sa plaque de renforcement 13,14, présente en son centre, un perçage 17,1E, pour le pas sage de l'entretoise qui présente quant à elle ç l'une de ses extrémités une tête 19 et à l'autre extrémité une partie filetée 20 recevant un écrou 21.By this rupture of the spacer 13, the tank, until then very flat, can, under pressure, deform and tend towards a shape of greater capacity and more spherical and therefore capable of withstanding up to very high pressure, for example sixty bars, without running the risk of an explosion,
Each main wall 11,12 and its reinforcing plate 13,14, has in its center, a hole 17,1E, for the wise pitch of the spacer which has for its part ç at one of its ends a head 19 and at the other end a threaded part 20 receiving a nut 21.

Pour assurer l'étanchéité du passage de l'entretoise, la arexe le teAte 19 et l'écrou 21 prenna sur un joint 22,23, de préférence logé dans une gorge de la collerette 24,23, d'un manchon 26,27, soudé sur la plaque de renforcement et déchex- geant l'entretoise de contraintes de cisaillement. To seal the passage of the spacer, the arexe the teAte 19 and the nut 21 prenna on a gasket 22,23, preferably housed in a groove in the flange 24,23, of a sleeve 26,27 , welded to the reinforcement plate and breaking the shear stress spacer.

Dans une variante de réalisation, de part et d'autre de la section calibrée 16, l'entretoise est montée en série dans un circuit qui s'ouvre à la rupture de l'entretoise, ce qui par exemple peut commander un avertisseur sonore ou lumineux. In an alternative embodiment, on either side of the calibrated section 16, the spacer is mounted in series in a circuit which opens at the rupture of the spacer, which for example can control an audible warning device or luminous.

Dans une autre variante de réalisation, à l'entretoise est raccordée une jauge de contrainte permettant, par l'information quelle fournit, d'éviter une rupture en intervenant à temps pour faire redescendre la pression dans le réservoir. In another alternative embodiment, the spacer is connected to a strain gauge allowing, by the information it provides, to avoid rupture by intervening in time to bring the pressure down in the tank.

Indépendamment des éléments caractéristiques qui précèdent,le réservoir comprend évidemment d'autres éléments tels un orifice de remplissage 28 et un orifice de vidange 29 et éventuellement une prise de raccordement d'un élément manométrique.Independently of the foregoing characteristic elements, the reservoir obviously includes other elements such as a filling orifice 28 and a drainage orifice 29 and possibly a connection socket for a pressure element.

Ci-dessus, on a décrit un mode de réalisation d'un réservoir d'une certaine forme avec une seule entretoise, lequel mode de réalisation est estimé le plus avantageux, mais il est évident que ne sort pas du cadre de cette invention, un réservoir relativement plat d'une autre forme et/ou comportant plusieurs entretoises du type précité. Above, an embodiment of a reservoir of a certain shape with a single spacer has been described, which embodiment is considered the most advantageous, but it is obvious that it is not beyond the scope of this invention, a relatively flat tank of another shape and / or comprising several spacers of the aforementioned type.
