Abstract
The invention relates to a device for pneumatically conveying powder, the device having an injector with a conveying gas connection and a metering gas connection as well as a powder intake channel connected in terms of flow to the injector. To achieve the effect that the powder conveying device can be effectively flushed through in the cleaning mode of said device, it is provided according to the invention that a purging gas connection, which is connected or can be connected to a purging gas line, is provided between the negative pressure region of the injector and the powder intake opening of the powder intake channel for the feeding, as and when required, of purging gas, in particular compressed purging air. Furthermore, a shut-off element is assigned to the purging gas connection to prevent purging gas from being able to escape from the powder output opening of the powder intake channel.
