Abstract:
A nozzle angle regulator for adjustable nozzle mechanism, said mechanism comprising; a number of variable nozzle vanes, which are arranged along the circumference of the turbine and provided on the nozzle shafts which are supported on the nozzle mount fixed to the turbine casing in such a way that the nozzle vanes can rotate, and which vary the vane angle; a nozzle driving member having a ring shape for rotating the nozzle shafts of the nozzle vanes, the nozzle driving member being capable of rotating around the turbine shaft by the actuator; and a plurality of joint members of the same number as the nozzle vanes, which connect a plurality of nozzle shafts for nozzle vanes and the nozzle driving member, and which rotate the nozzle shafts with a swing motion forced by the nozzle driving member:wherein said nozzle angle regulator is provided with two full-opening stopper surfaces provided on at least two neighboring joint members to move said nozzle vanes towards the opening direction and stop said nozzle vanes at the full-opening position by contacting said two neighboring joint members to each other.
