An electrostatic spray nozzle that is positioned at an angle above horizontal and less than vertical having a body with an upper fluid emitting end and a lower bottom end. The body having an interior cavity therein. Within the cavity is a shim capable of conducting electricity that defines an opening at the fluid emitting end and a channel that joins the fluid emitting end opening to a supply of flowable material. The body has an enclosed electrode external adjacent to and below the emitting end. Both the shim and the electrode are electrically connected to a voltage source. The nozzle, in operation, bends the field adjacent the emitting end upwardly in accordance with the method of the invention.

Shoot-up electrostatic nozzle and method

In the broader aspects of the invention there is provided an improved nozzle, an improved nozzle assembly and an improved method in which the improved nozzle comprises a protrusion having an distal end and a collar extending backward from the distal end. The collar is surface free of discontinuities. The outer end has an edge and an adjacent point at which the charge is concentrated. The protrusion has a fluid passage. The fluid passage is sealed from the collar surface. The fluid passage has an outlet adjacent the edge. A conductor is disposed in the protrusion. The conductor extends into the passage and is immersed in the fluid being disposed.
