PCT No. PCT/CH86/00057 Sec. 371 Date Dec. 23, 1986 Sec. 102(e) Date Dec. 23, 1986 PCT Filed Apr. 28, 1986 PCT Pub. No. WO86/06302 PCT Pub. Date Nov. 6, 1986.A flame spray torch which comprises a torch body and a torch head exchangeably connected with each other. Injectors are inserted in recesses of the torch body partly projecting therefrom and extending into recesses of the torch head. Each injector communicates with a respective supply duct for combustion gas and oxidation gas, mixing chambers being provided respectively in each injector and in the torch head, the latter being provided with means to improve the gas mixing. The torque reduces the risk of back-firing and allows the attainment of optimum spraying conditions for a great variety of applications by permitting an easy exchange, particularly with respect to the injectors. |
