The invention claimed is: 1. A device for the homogeneous distribution and dispersion of a fluid within an enclosure, comprising a diffusion chamber designated to be located at least partially inside the enclosure, substantially on the axis of a conduit supplying fluid to the enclosure, and to be inserted into the conduit, wherein the diffusion chamber comprises on the totality of its lateral walls means of discharging the fluid into a section of the enclosure being filled, and wherein the diffusion chamber comprises a single-unit assembly comprising: a first perforated plate, designed to be located upstream in the direction of fluid flow and allowing the supply of fluid to the diffusion chamber; a second perforated plate located downstream and designed to evacuate part of the fluid towards the inside of the enclosure, the first and second perforated plates having a shape and dimensions substantially identical to those of a transversal section of the conduit to be fitted, and being pierced with holes distributed in a substantially regular fashion across their surface; lateral bands, regularly spaced from one another, placed perpendicularly to the first and second perforated plates and joining them at their periphery, either directly or by means of a skirt; and at least one insert comprising a ring-shaped crown of an outer diameter identical to the inner diameter of the diffusion chamber, the ring-shaped crown being placed perpendicularly to the axis of the supply conduit and projecting towards the inside of the diffusion chamber from the lateral wall or walls thereof, to which it is rigidly affixed, such as to form a lateral obstacle to the flow of the fluid, wherein the surface area of the at least one insert is sufficient for creating, in an upstream section of the diffusion chamber, a pressure superior to that in a downstream section, such as to enforce the supply of fluid to the outermost region of a transversal section of the enclosure. 2. The device according to claim 1, wherein the at least one insert is located in the diffusion chamber at a distance from the first perforated plate comprised between 25% and 75% of the distance separating the first perforated plate from the second perforated plate. 3. The device according to claim 1, wherein the full surface area of the at least one insert represents between 20% and 80% of a transversal section of the diffusion chamber. 4. The device according to claim 1, wherein the fraction of the surface occupied by the perforations on the first perforated plate is greater than the fraction of the surface occupied by the perforations on the second perforated plate. 5. The device according to claim 1, wherein the perforations on the first perforated plate occupy between 10% and 50% of the surface area of the first perforated plate. 6. The device according to claim 1, wherein the perforations on the second perforated plate occupy between 5% and 25% of the surface area of the second perforated plate. 7. The device according to claim 1, wherein intervals between the lateral bands represent between 30% and 70% of an external lateral surface area of the diffusion chamber. 8. The device according to claim 1, wherein the skirt extends from the first perforated plate over a length representing between 10% and 30% of the distance separating the first perforated plate from the second perforated plate. 9. A method of homogeneously distributing a fluid within an enclosure, comprising inserting the device of claim 1 into a supply pipe of the enclosure or into a ring-shaped opening of the enclosure to which the supply pipe is connected, wherein the diffusion chamber of the device has an external transversal section substantially equal to an internal transversal section of the supply pipe to the enclosure or of the ring-shaped opening of the enclosure to which the supply pipe is connected, and wherein the device is inserted into the supply pipe of the enclosure or into the ring-shaped opening to a distance representing between 5% and 50% of its length. 10. The method of homogeneously distributing a fluid within an enclosure according to claim 9, wherein the enclosure is a chemical reactor designated for the processing of a charge which constitutes the fluid to be distributed within the enclosure. 11. The method of homogeneously distributing a fluid within an enclosure according to claim 10, wherein the reactor is a reactor comprising a fixed catalyst bed. 12. The device according to claim 1, wherein the diffusion chamber is inserted into the conduit at the connection between the conduit and the enclosure. 13. The device according to claim 2, wherein the at least one insert is located in the diffusion chamber at a distance from the first perforated plate comprised between 50% and 60% of the distance separating the first perforated plate from the second perforated plate. 14. The device according to claim 3, wherein the full surface area of the at least one insert represents between 40% and 60% of the transversal section of the diffusion chamber. 15. The device according to claim 5, wherein the perforations on the first perforated plate occupy one-third of the surface area of the first perforated plate. 16. The device according to claim 6, wherein the perforations on the second perforated plate occupy between 5% and 10% of the surface area of the second perforated plate. 17. The device according to claim 7, wherein intervals between the lateral bands represent between 40% and 60% of the external lateral surface area of the diffusion chamber. 18. The method of homogeneously distributing a fluid within an enclosure according to claim 9, wherein the device is inserted into the supply pipe of the enclosure or into the ring-shaped opening to a distance representing between 20% and 40% of its length. 19. The method of homogeneously distributing a fluid within an enclosure according to claim 10, wherein the charge comprises a hydrocarbon charge.
