Definitions

  • the technical sector of the present invention is that enclosures intended to contain fluids under pressure, such as tanks subjected to internal pressure, and more particularly petroleum gas tanks liquefied, known as LPG, for vehicles.
  • fluids under pressure such as tanks subjected to internal pressure, and more particularly petroleum gas tanks liquefied, known as LPG, for vehicles.
  • enclosures intended to contain pressurized fluids are made of a material sheet metal, formed to obtain a reservoir substantially cylindrical, the ends of which appear in the form of a portion of a sphere.
  • LPG tanks used for example in automobiles are cylindrical as previously described or toric. Their present shape the advantage of being well suited to a uniform distribution constraints on the periphery of the tank.
  • toroidal tanks are mounted at the location of the spare tire. Their capacity is limited due to the lack of space available for this location.
  • Cylindrical tanks are generally arranged at the bottom of the trunk of the automobile, where they reduce so considerable the volume of it, especially as the compartment which is intended to accommodate them is parallelepiped and the volume between the angles of the compartment and the arc of the tank is empty. he there is therefore a loss of useful volume, both for the trunk and for the tank.
  • Cylindrical tanks can also be mounted under the rear overhang trunk. In that case, the available space being limited in height, we use a cylindrical tank of small diameter, or more small diameter cylindrical tanks connected together by a pipe welded radially on the periphery of the cylinders. This solution avoids encroaching on the trunk volume. It is nevertheless expensive and does not allow not use the entire volume available under the chest since there is an empty part between the two cylindrical tanks attached.
  • the toric and cylindrical tanks therefore do not give not fully satisfied. Indeed, they are heavy because their walls are thick. In addition, they are often brought to be mounted in shaped compartments rectangular whose space is not available used optimally.
  • the purpose of the present invention is to provide a light and resistant tank. His characteristics mechanical must allow it to withstand the pressure internal involved in the storage of pressurized fluid, external stresses, such as a shock, when the vehicle is deformed during an accident and increasing internal pressure in the event of a vehicle fire.
  • the tank must have a shape making it suitable for be housed in compartments with forms composed of parallelepipeds according to document NL 8 300 434.
  • the present invention relates to a reservoir intended to contain a fluid under pressure and able to fit in a shaped compartment substantially parallelepiped, characterized in that it comprises at least two opposite vaulted walls provided with less than one well whose edges are curved toward the inside of the tank in a circular arc profile and a reinforcement comprising a seat at each of its ends flared according to the same profile in an arc of a circle as that of the well to fit into the corresponding well of each of the two opposite walls and maintain the spacing of these two walls.
  • the reservoir intended to contain fluid under pressure and able to be housed in a compartment of a vehicle is also characterized in that it comprises at least two opposite vaulted walls comprising at least one well whose edges are curved towards the inside of the tank according to a profile substantially in an arc of a circle and at least reinforcement whose ends are flared in shape corolla in the same arcuate profile as that from the well to fit edge to edge with the well correspondent of each of the two opposite walls of the tank and maintain the spacing of these two walls.
  • the reinforcement can be constituted by a solid bar connecting the seats together.
  • the reinforcement can be constituted by a hollow tube connecting the seats between them.
  • the reservoir according to the invention is characterized in that at least two opposite walls comprising the wells have a vault-shaped profile.
  • the reservoir according to the invention is characterized in that at least one of the other walls of the tank is domed.
  • the tank according to the invention is advantageously characterized in that the interior of the tank is presented in the form of an arch.
  • the tank according to the invention is advantageously characterized in that the seat of the reinforcement is applied to a portion of the well in which it is inserted.
  • the tank can have two sets of wells arranged in two parallel rows in which reinforcements are engaged.
  • the reinforcements are produced under the form of a single piece whose ends are in corolla.
  • the reinforcements are made in at at least three parts, one substantially cylindrical extended on both sides by a cap in the shape of corolla.
  • each reinforcement is constituted by a hollow tube connecting the edge of the wells to each other, made in the form of a single piece whose ends are corolla.
  • Reinforcements can also be made in at least three parts, one substantially cylindrical, extended by on either side by a corolla-shaped cap.
  • An advantage of the tank according to the invention consists in what its structure allows it to be light, to be resistant and able to deform without breaking.
  • Yet another advantage of the invention lies in the structure of the tank has continuity between the walls and the reinforcements, which improves the resistance of the tank to pressure.
  • the tank 1 shown in Figure 1 has a general curved shape with six walls defining a set of arches, two upper walls 2 and lower 3, two side walls 4 and 5 and two front walls 6 and rear 7. Each of the walls is obtained from a sheet metallic conforming to the desired curvature. Walls 2 and 3 are larger than the other walls and are joined by reinforcements described below.
  • the reservoir 1 can be produced under the shape of two half shells 8 assembled according to a plan longitudinal and joined by internal reinforcements 9. Only one quarter of a half shell is shown in Figure 2 for convenience.
  • the two half shells 8 and the reinforcements 9 can be assembled by welding.
  • the opposite walls 2 and 3 of each half-shell appear in the form of a vault whose concavity is directed towards inside the tank.
  • the upper vaulted wall 2 is connected to the adjacent curved side walls 4 and 6 by an extension 10 ensuring continuity in the evolution of the angles between the vaulted wall and the curved walls of the tank, so as to avoid the invention all sharp edges.
  • the plan joint 11 of wall 2 and four side walls adjacent 4-7 is rectangular with rounded edges at the corners. The radius of curvature of the curved faces 4-7 gradually evolves towards the radius of curvature of arched faces 2 and 3.
  • the two vaulted walls 2 and 3 of the tank have wells 12 of circular arc profile, the edges of which are curved in a continuous profile with that of the vaults. It is the multi-arch shape of the large walls 2 and 3 of the tank which optimizes its useful volume in a housing parallelepiped, while homogenizing the constraints in the walls.
  • the tank according to the invention can be made of varied manner. We can for example assemble by welding the six walls 2-7 made in isolation with planes of seal similar to seal 11 as can be seen on the figure 2. We can still make two half shells, possibly symmetrical, which we assemble according to a any joint plane. These two half shells are obtained by stamping and when provided symmetrical, they are obtained from the same mold.
  • the different wells 12 of the two opposite walls 2 and 3 of the tank are arranged opposite one another. They are designed to receive reinforcements 9. Reinforcements allow to take the efforts of the large walls arched 2 and 3 of the tank, so as to remove the bending moments at the junction between the vaulted walls and the curved walls.
  • FIG 3 there is shown a section of the wall 2 (or 3) practiced at the level of wells 12.
  • Two rows of wells 12a and 12b are provided at the walls 2 and 3.
  • Each well 12 has an arcuate profile oriented towards the inside of the tank and is terminated by an edge 14.
  • the reinforcements 9 are constituted by a spacer full flared at each of its ends, giving it thus a form of valve.
  • Each reinforcement has a rod 13 whose diameter is identical to that of the edge 14 of the well 12 opening into the interior of the reservoir and a seat 15 at each end with a radius of curvature corresponds to that of the arc-shaped profile of the wells 12 practiced in the vaulted walls 2 and 3 of the tank and into which it is introduced.
  • the reinforcements 9 are constituted by a tube 16 flared at each of its ends to define a seat 17 whose radius of curvature corresponds to that of the arc-shaped profile of the wells 12 practiced in the vaulted walls 2 and 3 of the tank.
  • the rupture pressure of a reservoir thus produced with tubular or full reinforcements is 12.10 6 Pa for a total mass of the order of 45 kg, a useful volume of 95 liters and a useful volume / bulk volume ratio of 0, 78.
  • the rod 10 of the reinforcements 3 could have a variable diameter and be thinned towards the joint plane 6.
  • FIG 8 there is shown a section of the wall 2 practiced at wells 20.
  • Two rows of wells 20a and 20b are for example provided at each wall 2.
  • Each well 20 has an arcuate profile oriented towards the inside of the tank whose terminal edge comes in continuity with the edge of the reinforcement 21 opposite. So, a weld 22 can be made edge to edge between the well 20a and the reinforcement 21a which does not modify the stresses in the tank when it is filled with a fluid under pressure.
  • the reinforcement 21a is tubular with a flared end in the shape of a corolla; but, we could use a reinforcement in the same way consisting of a solid rod.
  • a reinforcement 21b appearing under the form of a tube extended by a cap 23 having a tubular end connected by the weld 24 to the reinforcement 21b and a flared end in the shape of a corolla connected to the well 20b by the weld 25.
  • the welds 24 and 25 are carried out as explained previously edge to edge. This realization allows to better control the process of manufacturing.
  • edge welding is understood to mean on board a joint weld with weld double-sided, a joined assembly in a single weld, a non-joined assembly in a single weld with batten removable, an assembly with welded edge or a assembly with corner weld on permanent lath.
