Abstract
PURPOSE: To reduce nozzle sound by a simple means, by providing sound absorbing material on a blade inner circumferential part of an air turbine. CONSTITUTION: Air sucked from a suction port strongly collides with a blade 15a of an air turbine 15 to rotate the air turbine 15 at high speed, when the blade 15a cuts a jet current to generate quick pressure change to cause generation of noise. Sound absorbing material 17 is provided at a center part of the air turbine 15 which is close to the sound source. This pressure change is efficiently absorbed by the sound absorbing material 17, so nozzle noise can be largely reduced especially. In addition, pressure fluctuation is also generated at the time when the blade 15a of the air turbine 15 passes around an air communication hole, which becomes an cause of nozzle noise and other noise, but in this case, this pressure fluctuation can be absorbed to reduce noise because the sound absorbing material 17 is positioned at a center of the air turbine 15.
