Patent ID: 8888018

Claim:
A system for dispensing pulverulent coating material consisting essentially of a source of pulverulent coating material, a source of compressed gas, a nozzle coupled to the source of pulverulent material, the nozzle providing an opening through which the pulverulent material is dispensed, a deflector spaced from the opening to aid in shaping a cloud of dispensed coating material, a source of high-magnitude electrostatic potential coupled to impart electrostatic potential to the dispensed coating material, wherein the deflector includes an outwardly flaring surface against which the pulverulent material impinges to shape the cloud of dispensed coating material and at least one first passageway extending with a radial component of the deflector and communicating with the source of compressed gas to direct gas with a radial component into the cloud of dispensed coating material, the deflector including a flat front surface and the at least one first passageway angled toward the front surface and positioned radially inward from the outwardly flaring surface, wherein the deflector includes a body including the front surface of the deflector, and a hub including a front surface and a skirt, the hub mounted to the front surface of the body so that the skirt abuts the front surface of the body to create a gallery behind the front surface of the hub and within the skirt, the gallery being in communication with the source of compressed gas, the hub further including the at least one first passageway and a rearward threaded section to mount the hub to a complementary threaded region of the body, the at least one first passageway extending through the skirt from the gallery to the exterior of the hub.
