Abstract
Electrostatic spraying apparatus comprising a housing having an opening, liquid atomization means and induction charging electrode means mounted in said housing to deliver an electrically charged spray of liquid particles outwardly through the opening, inlet means to said housing for delivering to the housing a flow of gas for subsequent envelopment of the electrically charged spray of liquid particles upon exit from the housing, and repelling electrode means of a polarity the same as the electrically charged spray and defining an electrical repulsion zone for repelling said spray immediately prior to and after the exiting of said spray from the opening. Relatedly disclosed are an electrostatic induction charging gas shroud adapter and a repelling electrode adapter, each to be employed with appropriate atomization means to deliver an electrically charged spray of liquid particles as described above.
