Abstract

본 발명은 토출압 변동에 영향을 받지 않고 토출 용량을 원활하게 가변 제어하며 또한, 압축 가스를 효율적으로 공급 가능한 가변 용량형 요동 사판식 압축기를 제공하는 것을 특징으로 한다.
토출실(23)에서 크랭크실(5)로 토출 가스를 공급하는 가스공급 경로(R)의 도중에 자동 유량 조절 밸브(40)를 설치한다. 자동 유량 조절 밸브(40)는 밸브 구멍(46)을 매개로 서로 연이어 통하는 토출 압력실(41)과 중간압실(42)을 구비한다. 중간압실(42)은 벨로우즈(48)에 의해 2개의 방으로 구획되어 있고 벨로우즈 내실(42b)은 크랭크실(5)에 연이어 통하게 되며 벨로우즈 외실(42a)은 압축구멍(51)을 매개로 크랭크실(5)에 연이어 통하게 되어 있다. 벨로우즈(48)의 상단부에는 밸브 본체(47)가 접속되어 있으며 토출 압력실(41)안에 있어서 밸브 본체(47)의 머리부분이 밸브 구멍(46)에 분리접속한다.
