Abstract
An apparatus for the flame spraying of powder materials by means of an autogenous flame comprising a nozzle carrier which has a burner nozzle and which projects into a guide opening of a preferably tubular attachment body provided with coolant guide means surrounding the burner nozzle, in particular an attachment body which is provided with an accelerating tube, is to be improved in that the nozzle carrier (10) is surrounded by a nozzle means (30) for construction of the flame and the nozzle means has an outlet opening or openings for constricting gas, the opening or openings extending axially or radially relative to the burner nozzle (11). The constricting gas is supplied through an annular stabilization chamber (28). In an embodiment the stabilization chamber (28) is of variable and is provided with an annular discharge gap (34) as the outlet opening.
