<p>PURPOSE:To reduce noise and vibration arising from a nozzle guide vane, by constituting a side wall of the nozzle guide vane of a side late, separately prepared from a partition, and detaching the point end part of the partition and the nozzle guide vane from a turbine impeller inlet. CONSTITUTION:A turbine scroll 14 is divided into two scroll chambers 14a, 14b by a partition 15. A guide vane 16c is provided in a nozzle part 16a communicating with the scroll chamber 14b. A side plate 15b which is separately provided from the partition 15 consisting of high heat resisting material in relatively small thickness, is inserted between the partition 15 and the nozzle guide vane 16c by detaching its trailing edge and also a point end part 15a of the partition 15, to the same extent to the trailing edge of the nozzle guide vane, from a turbine impeller inlet part 11a, and a point end part 15a' of said side plate 15b is placed approaching to the turbine impeller inlet part 11a.</p> |
