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.

Rotating projector and method for spraying a coating product

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.

Rotary spray device and method of spraying coating product using such a rotary spray device

This spraying member () comprises at least one outer bowl () and one inner bowl (), each bowl defining a spraying edge (), one inner spreading surface () and one outer surface (). The inner bowl () is positioned radially on the inside of the outer bowl (), whereas a volume (V) defined between the inner surface () of the outer bowl () and the outer surface () of the inner bowl () has a thickness (e), corresponding to the distance between this inner surface () and this outer surface (), decreasing between a first value (e), taken at the zone for inlet of cleaning product into the volume (V), and a second value (e), taken at the spraying edge () of the outer bowl (). The spraying member () comprises means () for the central supply of the inner spreading surfaces ().

Spraying member, spraying device comprising such a member, spraying installation and method of cleaning such a member

The present disclosure describes an atomizer having a body with an inner portion and an outer portion; an atomizer member; and outlet channels about the spraying axis (X) for ejecting air so as to shape the spray of material. The atomizer also has an outlet chamber communicating with the outlet channels; and an inlet duct for feeding air to the outlet channels. The atomizer also includes at least two intermediate chambers juxtaposed and extending about the spraying axis (X); axial intermediate channels, two juxtaposed intermediate chambers being interconnected via a set of intermediate channels distributed about the spraying axis (X); and outlet ducts distributed about the spraying axis (X).
