    Abstract: The electrostatic spray device includes a liquid sprayer including a nozzle that spouts a liquid; a voltage applicator that applies a voltage between the liquid sprayer and a heteropolar portion functioning as a pole opposite a pole of the liquid sprayer to generate an electrostatic force for causing the liquid to separate from a distal end of the nozzle in a charging state; and a stabilization electrode that maintains a stable spraying state of the liquid even when a pressure is applied to the liquid to supply the nozzle with the liquid. The stabilization electrode has an electric potential identical to an electric potential of the liquid sprayer, and is disposed near the nozzle such that a jet portion formed at a front of the nozzle by a linear extension of the liquid has a length longer than a length of the jet portion before the stabilization electrode is provided.

    Abstract: A working chamber system for the surface treatment of workpieces comprises at least one tightly closable work chamber (101), a frame-like workpiece holder (10, 20, 30) which is displaceable on a guide rail between a mounting position outside the work chamber (101) and a working position in the work chamber (101), and a manipulator which, as seen in plan view, is arranged next to a group of parallel guide rails within the work chamber (101). At least one of the workpiece holders (10, 20, 30) has an external frame (11, 21, 31), via which it is guided in the guide rails, and an internal frame (12, 22, 32) which is surrounded by the external frame (11, 21, 31) in a transporting position and which is displaceable into a position outside the main plane of the external frame (11, 21, 31) in the mounting position and/or the working position.

    Abstract: A rotary atomizing head (7) is provided with an outer peripheral surface washing passage (14) open onto anatomizing head outer peripheral surface (13) for causing wash fluid supplied from a feed tube (6) to flow out into an annular clearance (20) between the rotary atomizing head (7) and a shaping air ring (15). An outflow opening (14C1) of an outflow passage (14C) constituting the outer peripheral surface washing passage (14) is provided in a position closer to the backside into the annular clearance (20) by a length dimension (L1) than a front end surface (17A) of a front ring section (17) constituting the shaping air ring (15). Further, the outflow opening (14C1) opens to the annular clearance (20) in an angle (α1) that is an acute angle to the atomizing head outer peripheral surface (13).
