Abstract
Rotating projector for a coating product including a spraying device having a circular spraying edge, driving means for driving the spraying device around a rotational axis, a body including primary openings arranged on a primary contour for ejecting primary air jets in a primary direction. The air jets having an axial component and an orthoradial component which are nonzero. The primary direction has a nonzero radial component, which is centrifugal relative to the rotation axis. Each primary jet extends along the rotational axis at a distance from the rotational axis than the radius of the spraying edge. The body includes secondary openings arranged on a secondary contour for ejecting the secondary air jets in a secondary direction having axial and centripetal radial components. The secondary jets hit an external surface of the spraying device. The contours coincide with a circle centered about the rotation axis.
