摘要
Appts. consists of two nozzles (5) slit longitudinally in their front region, with each wire fed through the internal bore of the corresp. nozzle. Appts. has a wrapper element (10) covering the region (5a) of the nozzles and having a central opening for passage of the spray wires (7). Furthermore, the inner sides of the nozzles rest on sliding surface (4a) arranged centrally on an axially movable gas spray nozzle (4). Both the gas spray nozzle (4) and the wrapper element (10) are made of a dielectric material. Region of the inner surface of the contact nozzle (5) is pref. located in the flow path of the spray gas. Wrapper element (10) os the contact nozzles is pref. tightened by a nut (9) or a similar device against a shoulder element. Slit in the nozzle region (5a) is pref. located roughly perpendicular to the bearing area of the wrapper element (10). Wrapper element (10) can be shaped as a part of annular nozzle for supplying another stream of spray gas. Wrapper element (10) can also be shaped so that its central opening is located either over the spray wires (7) over the cylindrical part of the contact nozzles (5). USE/ADVANTAGE - Used in metal spraying installations. Good electrical contact properties and better conditions for adjustment and centering of the contact nozzles, are obtd..
