Abstract

Le pistolet de pulvérisation (10), destiné à la pulvérisation de matières conductrices de l'électricité, est muni d'un écran (24) empechant l'accumulation de dépots de voile conducteurs de l'électricité sur des parties de surface non conductrices préalablement déterminées (26) du pistolet (10). L'écran (24) évite ainsi la formation d'un circuit électrique entre une électrode chargée (18) et un élément de suppport mis à la terre (22) du pistolet. Le pistolet convient en particulier au dépot par pulvérisation à grand volume de peintures conductrices de l'électricité.
