END DEVICE FOR SUPPRESSION OF HYDRODYNAMIC NOISE

摘要

FIELD: mechanical engineering; devices for suppression of noise in hydraulic and air systems. SUBSTANCE: device is provided with silencer used as prototype which is made in form of perforated envelope with high coefficient of perforation terminating in rubber insert having taper chambers charged with air; this insert rests against watertight blank. EFFECT: enhanced acoustic efficiency of noise suppression; dampening of vibrations, extended field of application due to reduction of vibratory energy of hydrodynamic noise at increased total acoustic resistance of device.
