摘要

Device for pneumatic or hydraulic conveying of dust-like, powdery or granular bulk material, with a supply line, an axially parallel inner tube in the feed line, which has openings in intervals and flow resistances in the internal tube, which in the area of the openings a aufströmseitige and an outflow-side surface as a result of which outlet openings in the feed line and inlet openings in the inner tube are formed for the pumping medium, wherein the aufströmseitige surface with the axis of the inner tube forms an angle 90° and the incident flow deflects towards the outlet port.
