Abstract

본 발명은 밀폐형 회전식 압축기의 소음저감장치에 관한 것으로, 종래의 소음저감용 공명형 소음기는 공명공간(20)에 유입로(21)가 1개로 고정되어 있는 특정한 주파수 대역 한 곳에서만 소음감쇠효과가 나타나기 때문에 압축기 전체의 소음을 감소시키는데는 미흡한 문제점이 있었는 바, 토출통로 주변부의 실린더 또는 상,하베어링의 일정부위에 공명공간과 유입로를 2개소 이상 형성된 공명형 소음기를 설치하여 특정 주파수 2부분 이상에서 소음감쇠가 이루어지도록 구성한 본 발명을 제공하여 압축기의 압축실 내의 냉매가스가 압축되어 토출공으로 토출시 발생되는 고압력 주파수의 압력 맥동으로 인한 소음을 공명형 소음기를 설치함으로써 감소시키도록 한 것이다.The present invention relates to a noise reduction device of a hermetic rotary compressor, and the conventional noise reduction resonance type silencer has a noise damping effect only at one specific frequency band where one inflow passage 21 is fixed to the resonance space 20. There was a problem in reducing the noise of the whole compressor because it appeared, the resonance silencer formed with two or more resonant spaces and inlet passages in the cylinder or the upper and lower bearings at the periphery of the discharge passage. By providing the present invention configured to the noise attenuation as described above is to reduce the noise due to the pressure pulsation of the high pressure frequency generated when the refrigerant gas in the compression chamber of the compressor is compressed and discharged to the discharge hole by installing a resonance silencer.
