<p>The invention relates to a device for forming a junction between a main duct element and an intersecting duct element, where the main duct element is used for fluid flow substantially in one direction, and where at least a portion of the intersecting duct element is passed through and is enclosed by the main duct element. The invention is characterized in that the portion (3b) of the intersecting duct element is adapted to the fluid flow-through (15) in the main duct element (2), the portion (3b) either on its own or together with any profile elements (3a, 3c) mounted thereon having an external cross section (8) which has a first, rounded end (8a) upstream of the fluid flow-through (15) and a second end (8c) which is more pointed than the first, rounded end (8a) downstream of the fluid flow-through (15).</p> |
