Abstract
656,430. Centrifugal compressors &c. MASCHINENFABRIK OERLIKON. Jan. 11, 1949, No. 780. Convention date, Jan. 26, 1948. [Class 110(i)] Noise in centrifugal compressors and blowers is reduced by an acoustic resonator, situated at the diffuser and tuned to the rotor vane frequency. Resonators 4, which are provided in the wall of the casing 2 near the inlets of diffusers 3, each comprise either a recess in the wall or, as shown, a tube 5 closed at one end. The tuning is varied by an adjustable piston 7.
