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

摘要

it is equipped with the first means (4) capable of magnetic couplingcooperate with second means (52, 54) of the magnetic couplingfixed on a rotating part) of a projector (5),the first (4) and second (52, 54), coupling means being able to exerciseat least part of the axial force (f3) resulting in rotation of the couplingbowl (3) with a corresponding drive body (11). the radial width(42) of a surface (s42), which is defined by the first ring orcoupling means (4) is greater than the radial width (s) of totalcoupling means (52, 54) carried by the rotary part (5).
