도 2는 종래 기술에 따른 압축기용 머플러의 냉매흡입관의 결합구조를 나타내는 단면도로서, 상기 머플러는 흡입머플러이다.Figure 2 is a cross-sectional view showing a coupling structure of the refrigerant suction pipe of the compressor muffler according to the prior art, the muffler is a suction muffler.

상기 흡입머플러(13)는 일정한 공간을 형성한 몸체(21)와, 상기 몸체(21)의 일측으로 돌출 형성되어 냉매를 유입하기 위한 흡입구(23)와, 상기 흡입구(23)를 통하여 유입된 냉매를 압축 기구부(7)측으로 보내기 위한 한 쌍의 유출구(25)를 포함한다.The suction muffler 13 has a body 21 having a predetermined space, a suction port 23 protruding to one side of the body 21 to introduce the refrigerant, and the refrigerant introduced through the suction port 23.
