Abstract
Electrostatic spray device for coating powder or liquid with at least one charging electrode for electrostatic charging the coating material. The device has at least one, and preferably a plurality, of counter electrodes for the electrostatic removal of free charges (electrons or ions) from the stream of sprayed coating material adjacent a coating material discharge nozzle on the device. The counter electrodes are carrier by a ring which is slipped onto a body of the device. A sleeve screwed onto the body holds the ring in an axial direction on the body. An electrical line for discharging the free charges from the counter electrodes is secured to the ring. The electrical line passes through and is confined in a bore in the body to prevent rotation and axial movement of the ring on the body. When the sleeve is removed from the body, the counter electrode ring and attached electrical line can be withdrawn from the body in the axial direction as a unit.
