1. A 90°
- elbow adapted for use in pneumatic transport pipes and defining an inner elbow side and an outer elbow side, comprising;
a first pipe socket for attachment of a pipe;
a first pipe section defining an axis and being connected to said pipe socket, said first pipe section including a flared pipe shell extending at the inner elbow side to provide said first pipe section with a cross-sectional expansion expanding in a direction away from said first pipe socket;
a pipe bend including a quadrantal pipe shell connected to said flared pipe shell at the inner elbow side;
a second pipe section including a cylindrical shell which is connected to said quadrantal pipe shell at said inner elbow side, and a tapered pipe shell connected to said cylindrical shell at the outer elbow side to provide said second pipe section with a cross-sectional contraction contracting in a direction away from said quadrantal pipe shell;
said pipe bend further including a baffle plate arranged between said first pipe section and said second pipe section and connected thereto at the outer elbow side and being oriented relative to said axis of said first pipe section at an angle between 55° and
65°
; and
a second pipe socket connected to said second pipe section for attachment of another pipe.

Abstract
A 90° 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° and 65° 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.

- elbow adapted for connecting one pipe to another pipe and defining an inner elbow side and an outer elbow side, comprising;
a first pipe section having first connecting means at one end for connection of the one pipe and including a continuously expanding cross section expanding in a direction away from said first connecting means at the inner elbow side; a second pipe section having second connection means for connection of the other pipe and having a continuously reducing cross section reducing in a direction toward said second connecting means at the outer elbow side; and a pipe bend extending between and connected to said first and second pipe sections and including a baffle plate connected to and arranged at the outer elbow side at an angle between about 55° and
65°
relative to the incoming flow through said first pipe section of bulk material.
