Abstract
The invention relates to a member (10) for spraying a coating product comprising a primary surface (20) for spreading the product and at least two secondary, inner (21) and outer (22) surfaces for spreading the product that extend downstream of the primary surface (20), the primary (20) and secondary (21, 22) surfaces being coaxial (X10-X10), the downstream portions of the secondary surfaces (21, 22) defining an inner spraying edge (23) and an outer spraying edge (24). The downstream portions (21b, 22b) of the secondary surfaces (21, 22) have, relative to one another, directions (A21, A22) that are overall divergent towards the downstream direction. The inner edge (23) has a diameter substantially smaller than the diameter of the outer edge (24).
