The invention relates to a spray bowl, a discharge device comprising one such bowl and a discharge installation comprising one such device. The inventive bowl (3) is provided with magnetic elements (36) which are disposed around a male part (32) which can be inserted into the central channel (12) of a drive member (1), said magnetic elements (36) forming outer radial collars in relation to the aforementioned male part (32). According to the invention, the bowl (3) of the discharge device is connected to a drive rotor (11). Moreover, the invention also comprises magnetic coupling means (36, 52) consisting of magnetic bodies (52) which are disposed on either side of at least one magnet (51) which is supported by the rotor (1) while the bowl (3) is provided with ribs (36) which are made from a magnetic material. The magnetic coupling force obtained comprises a radial component in relation to the axis (X-X') of rotation of the bowl (3). |
