Abstract
A 90.degree. elbow for pneumatic transport pipes includes a tubular asymmetric cross-sectional expansion at the entrance side, a baffle plate along the outer elbow side and a tubular asymmetric cross-sectional contraction at the exit side of the elbow. The baffle plate is arranged at an angle between about 55.degree. and 65.degree. relative to the incoming flow direction of bulk material. The inner elbow side is defined by a quadrantal pipe shell, with the remaining area being complemented by segments to provide a closed cross section.
