摘要

The powder delivery device has a rod-shaped housing (1), a fluidizing air channel feeding fluidizing air to a fluidizing unit and a delivery air channel (2) delivering delivery air to an injector nozzle (7), having a controlled feed air channel (3), which feeds controlled feed air to a catchment nozzle (8). A powder channel (4) for transport of powder is provided, which has first and second channel sections (4.1,4.3). The longitudinal axes (4.2,4.4) of the two channel sections are inclined to each other. The longitudinal axes (7.1,8.1) of the injector nozzle and the catchment nozzle run parallel to the longitudinal axis (4.4) of the second channel section (4.3).
