Abstract

The elbow (10) has guiding elements (26,27), which are led parallel to each other and to the curved inner walls (29) and external walls (25). The guiding elements with a manifold of a flat channel to a circular channel, exchanges from a flat channel to a circular channel in a straight piece direction flat channel. If required, the external guiding elements have another inner guiding element in elliptical form. The width of circular channel connection is proportionate to flat duct connection.
