<p><P>PROBLEM TO BE SOLVED: To provide a supercharger effectively preventing erosion caused by combustion residue included in exhaust gas and suppressing an increase of a production cost. <P>SOLUTION: A turbine impeller 15 is rotatably provided in a turbine housing 17, and nozzle blades 28 are fixedly provided at predetermined angle intervals around the turbine impeller. The nozzle blades form a nozzle blade ring 29 which directs exhaust gas flowing into the turbine housing, toward the center. The turbine housing has inside a tongue part for separating the flowing-in exhaust gas and exhaust gas swirling in the turbine housing after flowing therein. The tongue part is formed to locate one of the nozzle blades on the extension of the tongue part. <P>COPYRIGHT: (C)2007,JPO&INPIT</p> |
