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 through a pipe or an inlet pipe and an outlet pipe. CONSTITUTION: A dynamic vibration absorber(31) with characteristic frequency same with resonant frequency of an inlet pipe(22) or an outlet pipe(23) is installed on a peripheral surface of the inlet pipe or the outlet pipe and comprises a stiffness member(33) contacting the peripheral surface of the inlet pipe or the outlet pipe and a mass member(32) supported by an end of the stiffness member, receiving vibration of the inlet pipe or the outlet pipe and vibrating to absorber amplitude of vibration of the inlet pipe or the outlet pipe so as to absorber noise of frequency generated by transmission of vibration of a compressor(21) to the inlet pipe or the outlet pipe.
