The invention relates to a rotary projector for a coating product that comprises a spraying member (1) having at least one ridge (12) capable of forming a jet of product, a means for rotating the member (1), a stationary body (2) having primary (4) and secondary (6) openings formed on primary and secondary outlines surrounding the rotation axis (X1) of the member (1) and for respectively outputting primary and secondary air jets (J6). Each primary air jet is inclined relative to the rotation axis (X1) in a primary direction such that the primary air jet freely crosses the area where the ridge (12) is located, while each secondary air jet is inclined relative to the rotation axis (Xl) in a secondary direction (J6) having at least one axial component (A6) and one radial component (R6), said components (A6, R6) being such that the secondary air jet (J6) impinges on an outer surface (13) of the spraying member (1).
摘要:
An installation for spraying coating product, such as water-soluble or metallic paint to be sprayed onto automobile bodies, comprises a coating product change unit on a downstream side of which is at least one distribution pipe. This feeds at least one sprayer for the coating product. An intermediate storage tank for the coating product formed in the distribution pipe(s) consists of a section of the pipe itself. An arrangement is provided for feeding rinsing product into the distribution pipe(s) and, by virtue of a selective connection device, the coating product is propelled by the rinsing product during spraying.

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).

摘要:
The bowl according to the invention is equipped with first magnetic coupling means adapted to cooperate with second complementary magnetic coupling means fixed on a non-rotary part of a sprayer, these first and second coupling means being adapted to exert an at least partially axial effort inducing the coupling in rotation of the bowl with a corresponding drive member. The radial width of an annular or truncated surface defined by the first coupling means is greater than the total radial width of the coupling means borne by the non-rotary part.
