Claims

[Claims for Utility Model Registration] A supercharger having an exhaust turbine, a compressor driven by the exhaust turbine, and a variable turbine nozzle formed of a row of tiltable vanes located upstream of the exhaust turbine. The drive mechanism for tilting the vane includes an operating shaft passing through a hole drilled in a center housing of the supercharger, and an arm member fixed to the operating shaft;
A variable turbine comprising: an engagement means provided on the shaft portion of the vane so as to be engageable with the arm member, and a seal ring interposed between the hole and the operating shaft. Nozzle type supercharger.
