Abstract

본 발명은 클러치 없는 압축기의 부하 토크의 급격한 변동을 제어한다.
회전축(9)상에 지지된 사판(15)의 경사각이 최소 경사각으로 향하면 사판(15)이 흡입통로 개방 스프링(24)의 탄성력에 대항하여 전달통(28)및 차단체(21)를 누른다. 차단체(21)는 사판 경사각이 최소 경사각일때 위치 결정면(27)에 접하고, 흡입 통로(26)와 흡입실(3a)과의 연통을차단한다. 흡입실(3a)과 크랭크실(2a)은 압력방출 통로(14)에 의해 접속되고, 압력 방출 통로(14)상에는 전자 개폐 밸브(32)가 기재되어 있다. 제어 컴퓨터(Co)는 온도 감지기(39), 공조 장치 작동 스위치(40), 회전수 검출기(41)로부터의 검출 정보에기초하여 전자개폐 밸브(32)를 여자 및 소자 제어한다 크랭크실(2a)과 토출실(3b)은 압력 공급 통로 (31)를 거쳐서 연통되어 있다.
