In the state where the rolling piston 34 interlocked with the eccentric portion 24 formed at the bottom of the rotating shaft 23 is in contact with the vanes (not shown), the revolution of the eccentric portion 24 in the inner space of the cylinder 31 is performed. Done.

상기 롤링피스톤(34)의 공회전에 의한 실린더(31) 내부공간의 내주면과 상기 롤링피스톤(34)의 외주면에 의해 형선된 공간부의 체적변화로 고온저압의 냉매가스가 흡입관(40) 및 흡입포트(41)를 통해 실린더(31)의 내부공간으로 흡입되어 고온고압의 상태로 압축된다. Due to the volume change of the space portion formed by the inner circumferential surface of the inner space of the cylinder 31 and the outer circumferential surface of the rolling piston 34 due to the idling of the rolling piston 34, the refrigerant gas having a high temperature and low pressure is introduced into the suction pipe 40 and the suction port ( 41) is sucked into the inner space of the cylinder 31 is compressed to a state of high temperature and high pressure.

그 압축된 고온고압의 냉매 가스는 토출포트(42) 및 토출공(43)을 통해 상부베어링(32)과 소음기(44)의 사이의 공명공간을 통하여 공명 주파수의 소음을 저감시켜 토출된 후 밀폐형 압축기의 밀폐용기 본체(10)의 상측을 밀봉 결합하도록 용접 결합된 일체형 상부덮개부(14)의 덮개부(14)의 중심부에 상측으로 돌출되어 일체로 형성된 토출관부(13)으로 토출된다.The compressed high-temperature, high-pressure refrigerant gas is discharged by reducing the noise of the resonance frequency through the resonance space between the upper bearing 32 and the silencer 44 through the discharge port 42 and the discharge hole 43, and then closed. Protruding upward from the central portion of the cover portion 14 of the integral upper cover portion 14 welded to seal the upper side of the sealed container body 10 of the compressor is discharged to the discharge tube portion 13 formed integrally.

이상 설명한 바와 같이, 본 발명에 따르면, 밀폐형 압축기의 상부공간 공간을 밀폐시키도록 밀폐용기 본체 상단을 밀봉 결합되는 상부덮개의 상측으로 냉매 토출관을 돌출시켜 일체로 형성함으로서 재료비의 절감하고, 상부덮개와 냉매 토출관을 용접하는 용접공정을 삭제함으로서 작업공정의 감소로 인한 생산성을 향상과, 용접작업의 불량에서 기인하는 냉매의 누설을 방지하여 밀폐형 압축기의 신뢰성을 갖도록 하는 효과를 갖는다. As described above, according to the present invention, by lowering the material cost by forming the refrigerant discharge pipe integrally by projecting the upper portion of the upper cover to seal the upper end of the sealed container body to seal the upper space of the hermetic compressor, the upper cover And by eliminating the welding process for welding the refrigerant discharge tube has the effect of improving the productivity due to the reduction of the work process, and to prevent the leakage of the refrigerant caused by the failure of the welding operation to have the reliability of the hermetic compressor.
