Abstract

Uppfinningen avser ett utblåsmunstycke (1, la-b) omfattande en inloppsport och en utblåsyta med utblåshål (5a-g, 5h1-2), där utblåsytan är delad i utblåsområden med olika arealt utblåsmotstånd. Från inloppsporten sträcker sig tilloppskanaler (7a-c, 13a-c), där varje tilloppskanal (7a-c, 13a-c) löper till ett utblåsområde. Tilloppskanalema ger (7a-c, 13a-c) en styrning av utflödet genom respektive utblåsområde. De ger även en ökning av homogeniteten på flödet inom respektive utblåsområde.The invention relates to an exhaust nozzle (1, 1a-b) comprising an inlet port and an exhaust surface with exhaust holes (5a-g, 5h1-2), where the exhaust surface is divided into exhaust areas with different areal exhaust resistance. Supply channels (7a-c, 13a-c) extend from the inlet port, where each supply channel (7a-c, 13a-c) runs to an exhaust area. The supply channels (7a-c, 13a-c) provide control of the outflow through the respective exhaust area. They also provide an increase in the homogeneity of the flow within the respective exhaust area.
