Abstract

PURPOSE: To decrease the capacity of a servomotor by utilizing a force from the motor reasonably through adjusting the angle formed longitudinally by a lever and tangentially by a guide ring to a right angle at the time of a guide vane opening whereat an unbalanced torque becomes maximum.
CONSTITUTION: A guide ring 1, a guide vane 2 and a lever 3 are connected so as to have an angle α formed longitudinally by the lever 3 and tangentially by the guide ring 1 at a right angle when an opening of the guide vane 2 is kept at 45 degrees whereat an unbalanced torque becomes maximum, and an arrangement is such that the guide vane 2 can be operated at maximum torque somewhat larger than the maximum unbalanced torque. Thus the capacity of a servomotor to turn the guide ring 1 can be decreased.
