SPRAY BOWL, ROTARY PROJECTOR INCORPORATING SAID BOWL AND PROJECTION SYSTEM INCORPORATING SAID PROJECTOR

摘要

The bowl is provided with first magnetic coupling means (4) which can cooperate with additional second magnetic coupling means (52-54) which are fixed on a non-rotary part (5) of a projector, said first (4) and second (52-54) coupling means exerting an at least partially axial effort (F3) resulting in rotational coupling of the bowl (3) to a corresponding drive element (11). The radial width (l42) of an annular or sectional surface (S42) defined by the first coupling means (4) is greater than the total radial width (l'52) of the coupling means (52-54) borne by the non-rotary part (5).
