Abstract

1. 청구범위에 기재된 발명이 속한 기술분야 : 본 발명은 클러치리스 편측피스톤식 압축기에 관한 것이다.
2.발명이 해결하려고 하는 기술적과제 : 본 발명은 클러치리스압축기에 있어서 토오크변동을 제어하는 것을 목적으로 한다.
3. 발명의 해결방법의 요지 : 회전축(9)상에는 사판지지체(14)가 슬라이드가능하게 지지되어 있다. 사판 지지체(14)에 지지된 사판(15)의 경사각이 최소경사각이 되면 사관지지체(14)가 전달통(57) 및 차단체(21)을 누른다. 차단체(21)은 사파나경사각이 최소경사각일 때에 위치결정면(55)에 접하고, 흡입 톤로(54)와 흡입실(3a)는 노즐구멍(21d),차단체(21) 내부 및 압력개방통기구(21c)를 통해서 연결된다. 토출실(3b)에는 토출개폐밸브(60)가 수용되어 있다. 토출개폐밸브(70)은 사판경사각이 최소일 때에는 토출실 (3b)와 외부냉매회로(49)의 연결을 차단한다.
