<p><P>PROBLEM TO BE SOLVED: To provide a turbocharger capable of forming a welded coupled part to connect a disk with a vane support ring without generating any distortion if possible and forming a constant uniform clearance like screw connection as a result. <P>SOLUTION: This turbocharger of variable turbine geometry comprises a vane support ring assembly 1 including the vane support ring 2 and the disk 3 which can be fixed to the vane support ring 2 for creating a flow channel 4, and at least one support pin 5 of which first end part 6 is connected with the vane support ring 2 and second end part 7 is welded to the disk 3. The disk 3 has a recessed part to which a support pin end 7 is welded, and the recessed part is surrounded by a heat throttle part 14. <P>COPYRIGHT: (C)2006,JPO&NCIPI</p> |
