Abstract:
The bowl according to the invention is provided with magnetic elements disposed around a male part which is adapted to be engaged in a central channel of a drive member, the magnetic elements forming outer radial flanges with respect to this male part. In the spraying device, the bowl is associated with a drive rotor, magnetic coupling means being provided which comprise magnetic bodies disposed on either side of at least one magnet borne by the rotor, while the bowl bears ribs formed in a magnetic material. The effort of magnetic coupling obtained has a radial component with respect to the axis of rotation of the bowl.
