VARIABLE DISPLACEMENT TURBINE

摘要

By disposing a support pin (24) at a position in front of a front edge (19a) of a movable nozzle blade (19) in a state in which the movable nozzle blade (19) is located at a rating opening position B set between a maximum opening position A and a minimum opening position C, aerodynamic affect of the support pin when flow rate is small is reduced, and a turbine efficiency when the flow rate is small is enhanced.
