Abstract
Disclosed are a Venturi nozzle arrangement for powder conveying injectors and corresponding powder conveying injectors. The Venturi nozzle arrangement has a first region, which serves as a drive nozzle, and a second region, which serves as a collecting nozzle, wherein the second region has a channel that serves as a stream collecting channel with a longitudinal axis, and wherein the first region has a nozzle opening which lies axially opposite the stream collecting channel, the first and second regions of the nozzle arrangement being inseparably connected to one another as a combined component.
Claims25
A powder conveying injector for conveying coating powder comprising a drive nozzle and a collecting nozzle, wherein the collecting nozzle comprises a stream collecting channel disposed axially opposite from the drive nozzle at a distance, and wherein:
- the collecting nozzle and the drive nozzle are consolidated into one component such that the collecting nozzle and the drive nozzle can only be replaced simultaneously.
A powder conveying injector for conveying coating powder comprising a drive nozzle and a collecting nozzle, wherein the collecting nozzle comprises a stream collecting channel disposed axially opposite from the drive nozzle at a distance, and wherein:
- the drive nozzle comprises a powder inlet disposed axially opposite the stream collecting channel at a distance.
A Venturi nozzle assembly for powder conveying injectors, wherein the Venturi nozzle assembly has a first region serving as a drive nozzle and a second region serving as a collecting nozzle, wherein the second region comprises a channel having a longitudinal axis serving as a stream collecting channel, and wherein the first region comprises a nozzle opening axially opposite the stream collecting channel, wherein the first and the second region of the Venturi nozzle assembly are inseparably connected together as one consolidated component.
