Abstract:
1. 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 rotary 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 secondary surfaces having downstream portions defining respectively at least one inner spraying edge and at least one outer spraying edge, the at least one inner spraying edge being radially spaced from the at least one outer spraying edge, and the downstream portions of the secondary surfaces having, relative to one another, directions such that the product distributed from said outer secondary surface diverges from the product distributed from said inner secondary surface in the downstream direction, and wherein the inner spraying edge has a diameter substantially smaller than the diameter of the outer spraying edge.
