  • Powder spray gun comprising a wear resistant electrode support
    Patent number: 11925952
    Abstract: A spray nozzle assembly is provided with an electrode, a wear resistant member, and a compliant sleeve. The wear resistant member supports the electrode and is supported by the compliant sleeve. For coating operations that use abrasive powder such as porcelain enamel, the wear resistant member may comprise ceramic. The compliant sleeve may be made of an elastic material such as plastic, which allows one end of the compliant sleeve to receive an end of a glass powder tube. The wear resistant member may be in the form of a ceramic spider. The electrode may be installed in-line with a powder flow path defined by the powder tube, which extends through a spray gun body.
