PROCESS FOR MAKING A MULTIPLE DUCT DISTRIBUTOR AND DISTRIBUTOR

摘要

Process forming a multiple duct (5) distributor having a varying cross section where a work piece (1) is extruded having inner walls (2) forming multiple ducts (5), a first and second end section and a constant cross section. The work piece (1) is contracted at a first end section (a) of the work piece (1) and expanded at a second end section (e) of the work piece (1) leaving parts of the work piece having an increasing cross section during the expansion process. Distributor having inner walls (2) forming multiple ducts (5) which are maintained through the distributor. The distributor is made of a work piece (1) which is expanded over one section and contracted over a second section thereby forming a distributor having a varying cross section.
