ABSTRACT:
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.
