Abstract (en)
[origin: EP0412289A2] In the feed gas line (4) and in the metering gas line (24) of an injector (2), there is in each case a pressure-adjustment device (6,26) which can be adjusted with respect to the initial pressure. A gas flow meter (46) indicates the entire quantity of feed air and metering air flowing per time unit. As a result, the pressures of the feed air and of the metering air can be varied and, nevertheless, the entire quantity of gas in the powder/gas stream can be kept at a desired value in a simple manner. <IMAGE>
