It is provided in the main bearing 1 with one end of the discharge valve 3.

또한, 상기 실린더(12)의 흡입실(14)에는 냉매 가스가 실린더(12)의 내부로 유입되는 흡입구(20)가 형성되고, 상기 흡입구(20)는 밀폐 용기(5)의 측부에 설치되는 어큐뮬레이터(21) 및 냉매 유입관(22)에 의해 연결된다.In addition, a suction port 20 through which refrigerant gas flows into the cylinder 12 is formed in the suction chamber 14 of the cylinder 12, and the suction port 20 is provided at the side of the sealed container 5. It is connected by the accumulator 21 and the refrigerant inlet pipe 22.

그리고, 상기 토출 포트(17)의 측부에 위치하도록 실린더(12)의 일측에는 소정의 두께와 면적을 갖도록 형성된 베인(16)이 삽입되고, 상기 베인(16)은 스프링(23)에 의해 탄성적으로 지지되어 베인(16)의 일측 단부가 롤링 피스톤(13)에 접촉된 상태로 설치되며, 상기 밀폐 용기(5)내의 바닥면에는 슬라이딩이 일어나는 부품에 공급되는 오일이 채워져 있으며, 상기 밀폐 용기(5)의 상부에는 밀폐 용기(5) 내부에서 압축된 냉매 가스가 외부로 토출되는 토출관(24)이 설치되어 구성된다.In addition, a vane 16 formed to have a predetermined thickness and an area is inserted into one side of the cylinder 12 so as to be positioned at the side of the discharge port 17, and the vane 16 is elastic by a spring 23.

따라서, 밀폐형 회전식 압축기가 인가되는 전류에 의해 회전자(7)가 회전하면서 크랭크축(9)을 회전시키게 되면, 크랭크축(9)의 회전에 의해 크랭크축(9)의 편심부(10)에 결합되어 있는 롤링 피스톤(13)이 베인(16)과 접촉된 상태에서 실린더(12)의 압축 공간(P)에서 편심 회전하게 되고, 상기 롤링 피스톤(13)의 편심회전에 의해 실린더(12)에 형성된 압축 공간(P)의 체적 변화로 저온 및 저압의 냉매 가스가 어큐뮬레이터(21)에 연통 설치된 냉매 유입관(22)과 흡입구(20)를 통해 실린더(12)의 내부로 흡입되어 고온 및 고압의 상태로 압축된다.Therefore, when the crankshaft 9 is rotated while the rotor 7 rotates by the current applied by the hermetic rotary compressor, the crankshaft 9 rotates to the eccentric portion 10 of the crankshaft 9. In the state in which the combined rolling piston 13 is in contact with the vane 16, the eccentric rotation is performed in the compression space P of the cylinder 12, and the eccentric rotation of the rolling piston 13 is applied to the cylinder 12.

Compressed to a state.

이와 동시에, 압축된 고온 및 고압의 냉매 가스는 실린더(12)의 토출 포트(17)와 메인 베어링(1)의 토출공(2) 및 흡입 머플러(18)를 통해 실린더(12)의 외부로 토출되어 고정자(6)와 회전자(7) 사이를 통해서 밀폐 용기(5)내의 상부로 이동하여 토출관(24)을 통해 밀폐 용기(5)의 외부로 토출시키는 사이클을 반복하게 된다.At the same time, the compressed high-temperature and high-pressure refrigerant gas is discharged to the outside of the cylinder 12 through the discharge port 17 of the cylinder 12, the discharge hole 2 of the main bearing 1, and the suction muffler 18. Thus, the cycle between the stator 6 and the rotor 7 is moved upward in the sealed container 5 and discharged to the outside of the sealed container 5 through the discharge tube 24.

그러나, 이와 같은 종래 밀폐형 회전식 압축기는 작동시 고온 및 고압으로 압축된 냉매 가스가 실린더(12)의 외부로 토출될 때 메인 베어링(1)의 상면에 설치된 토출 밸브(3)가 그 상부의 리테이너(40)에 면접촉하여 강하게 부디치는 밸브 타격음이 사이클이 진행되는 동안 계속적으로 발생하게 되고, 상기와 같이 토출 밸브(3)가 리테이너(40)에 면접촉하여 발생하는 소음이 매우 크기 때문에 사람이 들었을 경우 아주 귀에 거슬리므로 불쾌감을 초래하게 되며, 압축기 전체의 소음 증가를 유발시키게 되어 압축기의 신뢰성을 저하시키게 되는 등의 많은 문제점이 있었다.However, such a conventional hermetic rotary compressor has a discharge valve 3 installed on the upper surface of the main bearing 1 when the refrigerant gas compressed at high temperature and high pressure is discharged to the outside of the cylinder 12 during operation. 40) The sound of the valve hitting hardly in contact with the surface is continuously generated during the cycle, and the noise generated by the discharge valve 3 in contact with the retainer 40 is very loud as described above. In this case, it is very annoying, causing discomfort, and causing an increase in the noise of the whole compressor, thereby degrading the reliability of the compressor.

따라서, 본 발명은 상기한 제반 문제점을 해결하기 위한 것으로서, 밀폐형 회전식 압축기의 작동시 고온 및 고압으로 압축된 냉매 가스가 토출될 때 압력차에 의해서 토출 밸브가 강한 힘으로 리테이너를 타격하는 것에 의해 발생하는 소음을 효율적으로 저감시킬 수 있도록 하여 압축기에서 발생되는 전체 소음을 감소시킬 수있을 뿐만 아니라, 청감음을 향상시킬 수 있는 밀폐형 회전식 압축기의 토출 밸브 소음 저감구조를 제공하는 데 그 목적이 있다.Accordingly, the present invention has been made to solve the above-mentioned problems, which is caused by the discharge valve hitting the retainer with a strong force when the refrigerant gas compressed at high temperature and high pressure is discharged during the operation of the hermetic rotary compressor. The purpose of the present invention is to provide a discharge valve noise reduction structure of a hermetic rotary compressor that can reduce the overall noise generated by the compressor by efficiently reducing the noise, and can improve the audible sound.
