ABSTRACT:
A long lasting elbow allowing sharp turns in particulate material handling systems without having undue wear of the elbow is formed with a chamber aligned with but axially offset from the entry port of the elbow. The effect of this chamber is to provide a rotating mass of the conveyed material against which the subsequent material impinges and is directed through the elbow without undue loss of velocity. A vent conduit connects the chamber to the elbow channel to allow purging to the chamber through a venturi action.
