Abstract
A rotary device for spraying a coating product is provided. The rotary device includes a spray member having an edge and able to form a jet of coating product, a device for driving the rotation of the spray member and a body which is fixed. The body that is fixed includes primary orifices arranged on a primary outline surrounding the axis of rotation and intended to eject a primary air jet in a primary direction and secondary orifices arranged on a secondary outline surrounding the axis of rotation and intended to eject a secondary air jet in a secondary direction. The respective orientations and positions of each primary direction and of each secondary direction cause combined jets to be formed, each resulting from the intersection between a primary air jet and a secondary air jet that are associated with one another, the region of intersection lying upstream of the edge.
