Spraying member, spraying device comprising such a member and spraying installation comprising such a device

A rotary spraying member for a device for spraying coating product, said spraying member being mounted for rotation when the device is spraying coating product, said rotary spraying member comprising a primary surface for distributing the coating product and an outer secondary surface for distributing the coating product from the primary surface, extending downstream of the primary surface, said spraying member further having a product distributing portion that rotates with said rotary spraying member when said rotary spraying member is in use, said product distributing portion providing an inner secondary surface extending downstream of the primary surface, and said spraying member having coating product passages disposed to conduct coating product from the primary surface to the outer secondary surface, the primary surface and secondary surfaces being coaxial and rotating with said product distribution surface when said product distribution surface rotates, the inner secondary surface having a downstream portion having a downstream end forming an inner spraying edge from which coating product is sprayed and the outer secondary surface having a downstream portion having a downstream end forming an outer spraying edge from which coating product is sprayed, the at least one inner spraying edge being radially spaced from the at least one outer spraying edge, and the inner secondary surface having a direction that is divergent in the downstream direction from the outer secondary surface, such that the product distributed from the inner spraying edge diverges from the product distributed from the outer spraying edge, and wherein the inner spraying edge has a diameter smaller than the diameter of the outer spraying edge.
