摘要： This invention relates to a triboelectric projector of pulverulent coating product, comprising a channel for charging the coating product, a supply conduit connecting a source of coating product to said projector, a mixture of air and of coating product circulating in said conduit, an injector of air for dilution and/or acceleration of said mixture of air and coating product, characterized in that the outlet orifice of said injector is disposed on the path of said mixture of air and coating product in an inner chamber of the projector, downstream of the admission of said conduit in said projector and upstream of the inlet of the charging channel. The invention also relates to a process for controlling such a projector, consisting in measuring the charge obtained in the charging channel and in servo-controlling by this charge the instantaneous flowrate of air injected by the injector.
