Abstract

L'invention concerne un système de maintien pour un pulvérisateur électrostatique, en particulier un pulvérisateur rotatif, pourvu d'un couplage comprenant une première et une deuxième plaque de couplage (8, 10) par le biais desquelles des conduites de fluide et des câbles conducteurs de courant peuvent être couplés et découplés pour l'alimentation du pulvérisateur. Selon l'invention, pour que ce système soit réalisé de manière robuste et facile à entretenir, un système de connecteurs centraux (16) pourvu de deux éléments connecteurs centraux conçus de manière complémentaire, des moyens de positionnement réalisés entre les plaques de couplage (8, 10), ainsi qu'un élément de couplage sous la forme d'un moyen de traction destiné à découpler et à coupler les plaques de couplage (8, 10) sont présents.
