Abstract: The subject matter of the application is a device for pneumatically or hydraulic feeding of dust-like, powdery or granulated bulk goods which has a feed line with an inner pipe mounted therein extending concentrically thereto, being provided with outlet and inlet openings. In order subject the bulk goods in the feed line of such a device to a continuous strong turbulence, so that no plugs of goods can form, but on the other hand to have the possibility to dissolve such plugs of goods if they form it is provided as a solution that a vertically disposed disk (5) is provided in the inner pipe (2) between an outlet and an inlet opening (3,4) which is provided with at least one opening (6) which preferably consists of a circular hole, being provided in the center of disk (5), or which consists of a slot (13). Thereby, the disk (5) may be eccentrically disposed between the outlet opening and inlet opening (3,4) and may be exchangeably mounted in inner pipe (2).
