상기 실린더(5a)의 흡입실(16)에는 냉매 가스가 실린더(5a)의 내부로 유입되는 흡입구(21)가 형성되고, 상기 흡입구(21)는 밀폐 용기(1a)의 측부에 설치되는 어큐뮬레이터(23) 및 냉매 유입관(22)에 의해 연결되어 있다.An intake port 21 through which refrigerant gas flows into the cylinder 5a is formed in the suction chamber 16 of the cylinder 5a, and the intake port 21 is an accumulator installed at the side of the sealed container 1a ( 23) and the refrigerant inlet pipe 22.
또한, 상기 토출 포트(19)의 측부에 위치하도록 실린더(5a)의 일측에는 소정의 두께와 면적을 갖도록 형성된 베인(18)이 삽입되고, 상기 베인(18)은 스프링(24)에 의해 탄성적으로 지지되어 베인(18)의 일측 단부가 롤링 피스톤(15)에 접촉되며, 상기 밀폐 용기(1a)내의 바닥면에는 슬라이딩이 일어나는 부품에 공급되는 오일이 채워져 있으며, 상기 밀폐 용기(1a)의 상부에는 밀폐 용기(1a) 내부에서 압축된 냉매 가스가 외부로 토출되는 토출관(25)이 설치되어 있다.In addition, a vane 18 formed to have a predetermined thickness and an area is inserted into one side of the cylinder 5a so as to be located at the side of the discharge port 19, and the vane 18 is elastic by a spring 24. And one end of the vane 18 is in contact with the rolling piston 15, and the bottom surface of the sealed container 1a is filled with oil supplied to a component in which sliding occurs, and an upper portion of the sealed container 1a is provided.

이와 같은 밀폐형 회전식 압축기는 인가되는 전류에 의해 회전자(9)가 회전하면서 회전축(11)을 회전시키게 되면, 회전축(11)의 회전에 의해 회전축(11)의 편심부(10)에 결합되어 있는 롤링 피스톤(15)이 베인(18)과 접촉된 상태에서 실린더(5a)의 압축 공간(P)에서 편심 회전하게 되고, 상기 롤링 피스톤(15)의 편심 회전에 의한 실린더(5a)에 형성된 압축 공간(P)의 체적 변화로 저온 및 저압의 냉매 가스가 어큐뮬레이터(23)에 연통 설치된 냉매 유입관(22)과 흡입구(21)를 통해 실린더(5a)의 내부로 흡입되어 고온 및 고압의 상태로 압축되며, 압축된 고온 및 고압의 냉매 가스는 실린더(5a)의 토출 포트(19) 및 메인 베어링(12)의 토출공(20)을 통해 실린더(5a)의 외부로 토출되어 고정자(8)와 회전자(9) 사이를 통해서 밀폐 용기(1a)내의 상부로 이동하여 토출관(25)을 통해 밀폐 용기(1a)의 외부로 토출되는 사이클을 반복하게 된다.The hermetic rotary compressor is coupled to the eccentric portion 10 of the rotary shaft 11 by the rotation of the rotary shaft 11 when the rotary shaft 11 rotates while the rotor 9 rotates by an applied current. In the state in which the rolling piston 15 is in contact with the vane 18, the compression space P of the cylinder 5a is eccentrically rotated, and the compression space is formed in the cylinder 5a by the eccentric rotation of the rolling piston 15.

This occurs, and the internal deformation generated in this way causes internal leakage during compression of the refrigerant, resulting in deterioration of the performance of the compressor, and deformation of the swelling portion increases friction with the vanes 18 during operation. There was a problem.
