냉동사이클을 거쳐 어큐물레이터(3)로 유입된 냉매는 흡입관(1)을 통해 회전식 압축기로 유입된다.The refrigerant introduced into the accumulator (3) through the refrigeration cycle is introduced into the rotary compressor through the suction pipe (1).

상기 고정자(21)에 전원이 인가되면 그 전원의 인가에 따라 회전자(22)가 고정자(21)의 내부에서 회전을 하게 되고, 이와 함께 회전축(31)이 회전을 하면서 롤링피스톤(36)이 실린더(30)내에서 편심 회전을 하게 되며, 그 롤링피스톤(36)의 편심회전에 따라 기상 냉매가 실린더(30)의 흡입공간으로 흡입되었다가 일정압력까지 지속적으로 압축되고, 그 실린더(30)의 압축공간 압력이 임계압력을 지나 케이싱(11)내의 압력보다 고압이 되는 순간 상기 상부 베어링(32)에 장착된 리드밸브(34)가 열리면서 흡입관(1)을 통해 유입된 냉매가 압축공간에서 케이싱(11)의 내부로 토출되며, 이 토출된 냉매는 케이싱(11)과 고정자(21) 사이의 틈새 또는 고정자(21)와 회전자(22) 사이의 틈새 등을 통해 상부로 이동하여 토출관(4)을 거쳐 냉동사이클시스템으로 배출된다.When power is applied to the stator 21, the rotor 22 rotates inside the stator 21 according to the application of the power, and the rolling piston 36 rotates while the rotating shaft 31 rotates. The eccentric rotation is performed in the cylinder 30, and according to the eccentric rotation of the rolling piston 36, the gaseous refrigerant is sucked into the suction space of the cylinder 30 and is continuously compressed to a predetermined pressure, and the cylinder 30 At the moment when the pressure of the compression space becomes higher than the pressure in the casing 11 through the critical pressure, the reed valve 34 mounted on the upper bearing 32 opens, and the refrigerant introduced through the suction pipe 1 is casing in the compression space. The discharged coolant is discharged to the inside of the container 11, and the discharged refrigerant moves upward through a gap between the casing 11 and the stator 21 or a gap between the stator 21 and the rotor 22 to discharge the pipe ( It is discharged to refrigeration cycle system through 4).

그리고 이와 같은 압축 과정에서 상부 베어링(32)에 고정된 리드밸브(34)는 머플러(38)에 일체로 형성된 리테이너(39)에 의해 열림상태가 한정되고 지지되면서 상부 베어링(32)에 형성된 토출공(32a)을 개폐하여 압축된 냉매 가스의 토출을 개폐하게 된다.In this compression process, the reed valve 34 fixed to the upper bearing 32 has an open state limited and supported by a retainer 39 formed integrally with the muffler 38, and the discharge hole formed in the upper bearing 32 is supported. The opening and closing of 32a opens and closes the discharge of the compressed refrigerant gas.

이상에서 설명한 바와 같은 본 발명은 로터리 압축기의 머플러에 리드밸브의 열림 상태를 한정하고 지지하기 위한 리테이너가 일체로 형성되고, 상기 리드밸브가 상기 일체형 리테이너에 형성된 고정돌기에 의해 상부 베어링의 고정홈에 고정되어 구성된 것으로, 별도의 리테이너와 볼트를 삭제할 수 있으므로 사용 부품수가 저감되고 조립공수가 저감되며, 이에 따라 제조 원가가 절감되는 이점이 있다.As described above, in the present invention, a retainer for defining and supporting an open state of the reed valve is integrally formed in the muffler of the rotary compressor, and the reed valve is formed in the fixing groove of the upper bearing by a fixing protrusion formed in the integrated retainer. It is configured to be fixed, since the separate retainer and the bolt can be deleted, the number of parts used is reduced and the assembly labor is reduced, thereby reducing the manufacturing cost.
