DYNAMIC VIBRATION ABSORBER OF COMPRESSOR FOR LOW NOISE

摘要

PURPOSE: A dynamic vibration absorber of compressor for low noise is provided to absorber vibrational noise by minimizing transmission of noise due to vibration generated by a vibration source of a compressor. CONSTITUTION: A dynamic vibration absorber(31) comprises a rigid member(33) contacting with a peripheral surface of an inlet pipe(22) or an outlet pipe(23) to have characteristic frequency same with resonant frequency of the inlet pipe or the outlet pipe so as to absorber frequency noise generated by transmission of vibration of a compressor(21) to the inlet pipe or the outlet pipe; a mass member(32) supported by an end of the rigid member, receiving vibration of the inlet pipe or the outlet pipe to vibrate and absorbing amplitude of vibration of the inlet pipe or the outlet pipe; and a damping member(34) having one end fixed to the mass member and the other end fixed on the peripheral surface of the inlet pipe or the outlet pipe to damp vibration of the mass member.
