Patent ID: 7455250

Claim:
An electrostatic spraying assembly comprising: a housing having a fluid inlet passage that is connectable to a fluid source and communicates with a plurality of first passageways each of which extends through the housing to a downstream end at a discharge end of the housing, said housing having a one piece housing body made of an electrically insulative material, said housing body being formed with an elongated internal channel disposed between front and rear housing walls and end walls at opposite ends of said channel, the whole of said one piece housing body including said front, rear and opposite end walls, a cover enclosing a top end of said housing body and elongated channel; and an electrode assembly including an elongated electrode header disposed in said internal channel and a plurality of elongate electrode elements each of which is supported in coaxial relation to and within a respective one of said first passageways in the housing, said internal channel defining a flow passageway between said fluid inlet passage and said first passageways for directing fluid to said first passageways and into contacting relation with said electrode elements, and said electrode header being electrically connectable to a voltage source for electrically charging said electrode elements and liquid flowing in contact therewith prior to discharge of the liquid from the spraying assembly.
