Abstract
The rotary atomizer coater is particularly adaptable to a high voltage rotary atomizer coater which can be robot mounted. A rotatable bell cup, which is mounted on a turbine driven shaft is positioned within a housing. A fluid tube within the housing includes a fluid discharge tip which extends through an inlet opening in the bell cup for supplying charged coating fluid directly to the inner surface of the bell cup interior which is open to atmosphere. An electrical resistor is mounted between the fluid discharge tip and a power supply within the housing. When a grounded object approaches the bell cup, the current between the bell cup and the grounded object will increase and voltage drop across the resistor results, thereby reducing the voltage at the bell cup and diminishing the potential for a high energy spark.
