VARIABLE-CAPACITY EXHAUST TURBOCHARGER EQUIPPED WITH VARIABLE-NOZZLE MECHANISM |
摘要 |
A variable-capacity exhaust turbocharger is provided which is equipped with a variable-nozzle mechanism having a lever plate and a peripheral structure capable of ensuring regular operability of a nozzle vane and of preventing an occurrence of local excessive stress by increasing rigidity of the lever plate without increasing a thickness of the lever plate. In a variable-capacity exhaust turbocharger equipped with a variable-nozzle mechanism including: a plurality of nozzle vanes; an annular drive ring; and a lever plate provided as many as the number of the nozzle vanes so that one end is connected to an engagement pin portion engaging with a groove portion formed in the drive ring and the other end is fixed to each nozzle vane, the drive ring is disposed between the lever plate and a nozzle mount in an axial direction, and the lever plate is curved in an axial direction from a surface of the lever plate connected to the fixed portion on the side of the nozzle vane so as to be connected to the groove portion of the drive ring.
