로터리 압축기의 토출유로구조Discharge channel structure of rotary compressor

종래 로터리 압축기의 토출유로구조는 제1도와 같이 냉매가스를 가두어두는 실린더(1)와, 상기 실린더(1)내부의 편심축에 축설되어 자전 및 공전하며 냉매가스를 압축 및 흡입하는 롤러(2)와, 상기 롤러(2)에 의해 흡입되어 압축된 냉매가스를 유로저항이 작게 토출시키도록 실린더(1)에 형성된 반달홈(3)과, 상기 실린더(1)와 접해있는 메인베어링(4)에 반달흠(3)과 동심을 갖고 형성되어 냉매가스를 토출하는 토출포트(5)와, 상기 토출포트(5)를 통해 토출되는 냉매가스를 개폐하는 밸브(6)로 구성하였다.The discharge passage structure of a conventional rotary compressor includes a cylinder 1 for confining a refrigerant gas as shown in FIG. 1, a roller 2 that rotates and revolves on an eccentric shaft in the cylinder 1 and compresses and sucks refrigerant gas, (3) formed in the cylinder (1) and a main bearing (4) in contact with the cylinder (1) so as to discharge the refrigerant gas sucked and compressed by the roller (2) A discharge port 5 concentrically formed with the half-moon blanks 3 for discharging the refrigerant gas and a valve 6 for opening and closing the refrigerant gas discharged through the discharge port 5.

미설명부호 7은 레조네이터이고 8은 서지홀이다.Reference numeral 7 denotes a resonator and reference numeral 8 denotes a surge hole.

이와 같이 구성된 종래의 로터리 압축기가 작동되면 실린더(1)내부에 형성된 롤러(2)가 자전 및 공전하고, 상기 롤러(2)의 공전에 따라 체적변화에 의해 흡입력이 발생하여 저온, 저압의 냉매가스가 실린더(1)내부로 유입되며, 상기 롤러(2)가 일정회전각 위치가 되면 유입된 냉매가 압축되고, 상기 롤러(2)가 계속 회전하여 일정압력이상이 되면 변브(6)가 열리고 냉매가스는 반달홈(3)과 토출포트(5)를 통해 토출되는 행정이 반복된다.When the conventional rotary compressor configured as described above is operated, the roller 2 formed in the cylinder 1 rotates and revolves, and a suction force is generated by the volume change due to the revolution of the roller 2, The refrigerant flows into the cylinder 1. When the roller 2 reaches a certain rotational angle position, the refrigerant introduced therein is compressed. When the roller 2 continues to rotate and becomes a certain pressure or more, The gas is discharged through the half-moon groove 3 and the discharge port 5 repeatedly.

그러나 이러한 종래의 로타리 압축기 토출유로구조는 메인베어링에 형성된 토출포트와 실린더에 형성된 반달홈의 중심이 같기 때문에 롤러의 회전각이 240 ° 이상이 되면 제2도와 같이 롤러가 토출포트내부까지 침투하여 토출포트의 유로면적(Ap)을 축소시킨다.However, since the center of the discharge port formed in the main bearing and the half-moon groove formed in the cylinder are the same, when the rotation angle of the roller exceeds 240 °, the roller penetrates into the discharge port as shown in FIG. Thereby reducing the flow path area Ap of the port.

롤러의 회전각이 커질수록 토출포트의 유로면적(Ap)에 비하여 롤러에 의해 침투된 유효토출면적(Ar)이 더욱더 축소되므로 실린더내부에서 생성된 고온, 고압의 냉매가스가 토출되는 것을 방해하게 되고, 이로인해 과압축손실이 증가하여 로터리 압축기의 성능을 저하시키는 문제점이 있었다.As the rotational angle of the roller becomes larger, the effective discharge area Ar penetrated by the roller is further reduced as compared with the flow passage area Ap of the discharge port, so that the high temperature and high pressure refrigerant gas generated inside the cylinder is prevented from being discharged , Which causes a problem that the compression loss is increased and the performance of the rotary compressor is deteriorated.

따라서 본 발명은 토출포트의 단면위치를 실린더 내부까지 침투하지 않게 형성하여 롤러의 회전각에 상관없이 항상 동일한 토출유로면적을 유지시킴으로써 로터리 압축기의 성능을 향상시키는 데 그 목적이 있다.Therefore, it is an object of the present invention to improve the performance of the rotary compressor by maintaining the cross-sectional position of the discharge port so as not to penetrate into the cylinder and always maintaining the same discharge passage area regardless of the rotation angle of the roller.
