Abstract

L'invention concerne un pulvérisateur, qui a : un boîtier supérieur (20) ; un boîtier inférieur (22) ; une lame fixe (30) ; des lames rotatives de pulvérisation fine (32) ; des lames rotatives de pulvérisation grossière (34) qui tournent autour d'une ligne centrale de rotation et qui pulvérisent de façon relativement grossière une pièce à travailler ; et une enceinte de capot (42) qui recouvre une partie des lames rotatives de pulvérisation grossière (34). Le boîtier inférieur (22) comporte un élément de support d'enceinte de capot (44) qui comprend une surface de réception (44a) qui reçoit l'enceinte de capot (42). Le boîtier supérieur (22) comporte un mécanisme de positionnement d'enceinte de capot (20d) qui vient en contact avec l'enceinte de capot (42), de façon à positionner ainsi l'enceinte de capot (42) dans la direction d'extension de la ligne centrale de rotation (C1) des lames rotatives.
