Definitions

  • the present invention relates to a reservoir for pressurized fluid, more particularly a fluid under high pressure, that is to say much greater than 1 MPa, typically greater than 5 MPa.
  • a particular, but not exclusive, field of application of the invention is that of tanks for liquefied gases, in particular tanks for gases liquefied propane (LPG) used on motor vehicles.
  • LPG gases liquefied propane
  • the object of the invention is to provide a reservoir for pressurized fluid. high does not have these drawbacks and for this purpose offers a reservoir comprising a plurality of elementary tanks connected in parallel to at least a collecting device, and sealing means making it possible to isolate a any of the elementary reservoirs in response to a pressure drop in this one.
  • the elementary reservoirs are advantageously formed by tubes.
  • a first advantage of the invention lies in very great ease adaptation to the space available. Indeed, the resistance to pressure is determined by the section and the wall thickness of each elementary tank, whatever or the general shape of the tank. It is then possible to distribute the volume of the tank in the available space, using elementary tanks of different lengths, or by arranging them in rows with varying numbers by row, or by grouping them into separate subsets linked together. This possibility is particularly interesting for motor vehicles for ensure that the tank housing does not penalize the useful volume.
  • the tank is simple and inexpensive to make. This is particularly so with elementary reservoirs in the form of tubes since the same tubes, cut to the desired lengths, allow tanks of all shapes and volumes to be produced.
  • these elementary reservoirs have an ability to contain an external pressure, typically a relative depression of the tank elementary, that any complex form of container prohibited without an architecture and specific sizing.
  • the present invention also offers the possibility of using various materials for elementary tanks, for example metals, alloys metallic or composite materials. These can be fiber reinforced carbon, "Kevlar” (registered trademark) or glass and resin matrix, by epoxy example.
  • Another advantage of the tank according to the invention is its safety. Thanks to the sealing means, damage to an elementary tank does not jeopardize the entire tank and its contents and limits the nuisance to the environment in the event of a leak. The low flow rate and the total volume of fluid escaping when only one elementary tank is damaged means that certain restrictions on use, such as for example prohibited access to road tunnels, may no longer be justified.
  • the closure means are in the form of a valve, for example formed by a flexible membrane, mounted at each end of elementary tank connected to a collector, the valve closing the end of the elementary reservoir in response to a drop in pressure prevailing in the elementary tank in relation to the pressure prevailing in the manifold.
  • a same flexible membrane can be mounted in a collectcur connected to a plurality ends of elementary tanks, to be common to several tanks elementary.
  • the tank can be fitted with a protective shield covering the minus each spaced area of the tank.
  • the shield advantageously has a shielding structure composed of a rigid covering sheet and a thick underlying layer of foam or honeycomb foam material.
  • the covering sheet for example of composite material, is capable of partially absorbing the energy of an impact or of a projectile and of transmitting the unabsorbed energy to the foam material which is capable of diffusing it over a large area. tank surface to avoid deformation of underlying structures. The value of the shocks to be absorbed without functional damage to the tank, as a whole, will condition the size of the shield.
  • FIGS 1 and 2 show a tank 10 consisting of a plurality of elementary tubes 20 connected in parallel to collectors 30.
  • the tubes 20 are arranged parallel to each other and in several superimposed rows, that is to say with a "bundle” arrangement.
  • the tubes have the same diameter and wall thickness. They are for example made of metal, such than steel or composite material, such as fiber-reinforced epoxy resin carbon or "Kevlar” (registered trademark).
  • the lengths of the tubes 20 and the numbers of tubes in the rows are chosen so as to optimally occupy the volume available for the tank housing, for example under the vehicle chassis.
  • the limits of the available volume are indicated by mixed lines.
  • each tube 20 is connected to a collector 30.
  • each collector 30 is in the form of a tube to which the elementary tubes 20 of the same row of tubes are connected.
  • the additional collectors 32, 34 connect the collectors to one another and in parallel 30 at both ends of the tank.
  • the collectors 32, 34 are connected to a line 36 connecting the reservoir 10 to an outlet for use and to an inlet for filling (not shown).
  • Each elementary tank end 20 is connected to a collector 30 by means of a connector 22 which is screwed or welded at one end 22a, at the end of the elementary tank 20 and which is screwed or welded at its other end, on the manifold tube 30.
  • the connector 22 penetrates slightly into the tube 30, to this other end 22b, this projecting inside the tube ( Figures 3, 4, 5).
  • each set collector at each end of the tank may be constituted by a coil traversing all the rows of tubes, or by a hollow flange.
  • the flange is then formed of two spaced parallel walls connected to each other in a sealed manner on their periphery, and one of the walls being provided with holes through which penetrate the fittings for the elementary tubes.
  • Figures 4 and 5 show a flexible membrane 40 which constitutes a means for closing an elementary tube 20 in the event that the pressure therein would fall for example following a rupture or deterioration resulting from a shock or impact from a projectile.
  • the membrane 40 is in the form of a strip of flexible material which extends over the entire length of the collector 30 with its faces perpendicular to the axes of the elementary tubes 20 of the row associated with the manifold. In this way, the membrane 40 constitutes a shared sealing means by all the tubes 20 of this row. At its ends, the membrane 40 is fixed at the closed ends of the collector 30 for example by gluing or by mechanical means.
  • the flexible membrane 40 is for example made of composite material composed of an elastomer reinforced with fibers. In normal operation, the membrane 40 is not deformed and leaves free access to the tubes 20 connected to the collecting tube 30 ( Figure 4). Maintaining identical pressure on each side of the membrane results from the fact that it does not divide the collector 30 in two longitudinal volumes isolated from each other in a leaktight manner.
  • the use of a flexible membrane is advantageous because of its low cost and reliability, since no moving parts are required.
  • the sealing means may be used, for example example of the non-return valves associated with each end of the elementary tube, the non-return valves can then be subjected to a slight restoring force which keeps open in the absence of depression in the elementary tubes correspondents.
  • a tank even for a high pressure fluid can therefore be significantly lighter than a single-body tank of the same capacity.
  • the tank In order to protect the elementary tubes against shocks and projectiles, it is desirable to provide the tank with a protective shield at the less on each exposed side.
  • Such a shield is shown only in Figure 6.
  • it comprises a layer of foam material 42, in particular in polyurethane foam, which envelops the bundle of elementary tubes 20 and the collecting tubes.
  • the layer 42 is coated by a rigid structure or shell 44 by example in a fiber reinforced epoxy resin matrix composite aramid.
  • the shell 44 can be formed by draping over the foam 42 of textures impregnated fibers and polymerization of the resin. Alternatively, the textures impregnated fibers can be draped on the inside of a mold the interior of which the reservoir is introduced to form the layer of foam covering.
  • This shield can also consist of an envelope of fibers, for example aramid, and of a material thickness in "nest" structure bee "in lieu and function of the foam material.
  • a protective shield is more particularly desirable when the elementary tubes (and the collecting tubes) are in one non-metallic material, in particular a composite material which is often less impact resistant and shows less plasticity than materials metal.
  • the rigid shell 44 distributes the pressure at the foam surface 42. This increases the pressure distribution, so that no deformation is induced on the rear face of the foam, in contact with elementary tank tubes.
  • a reservoir 10 which may have a complex shape but produced in a single set of elementary tubes 20.
  • FIG. 7 shows how to make the reservoir 10 in several sub-assemblies 12, 14.
  • Each sub-assembly comprises a plurality of elementary tubes, the lengths and arrangements are chosen according to the space available.
  • the sub-assemblies 12, 14 are connected to each other by one or more pipes 38.
