ABSTRACT:
A fan-type manifold for multi-cylinder internal-combustion engines has several first individual pipe sections which are connected in pairs to respective ones of second pipe sections. The first individual pipe sections are undeformed on the end and are cut off at a specific angle. The second pipe sections are produced by an internal high pressure deforming process. The first pipe sections are plugged into the second pipe sections at respective Y-type combining points to form Y-shaped connections and are sealingly welded to each other via surrounding fillet welds. One of the second pipe sections has an additional Y-type combining point for the lateral connection of the other second pipe sections, which are sealingly welded thereto via surrounding fillet welds.
