Abstract

흡입압력과 토출압력의 중간압력의 냉매가스를 크랭크실로 공급하고, 토출용량의 제어에 필요한 동력의 손실을 줄인다.
실린더블록(1)의 중심구멍(1b)와 후부하우징(4)의 격벽(4a)에 형성된 내주면(4b)등에 의해 형성된 밸브수용실(25)에 로타리밸브(26)을 회전축(10)에의해 회전가능하게 수용한다. 또, 이 로타리랠브(26)에 형성된 흡입통로(28) 및 흡입안내홈(29)에의해 흡입실(8) 내의 냉매가스를 실린더블록(1)의 통로(1c)를 통해서 흡입행정중의 실린더내의 작동실(30)으로 안내가능하게 형성한다. 그리고 전기한 로타리밸브(26)에 급기통로(33)으로 이루어진 연결로(26b)를 형성하고, 압축행정중의 작동실(30)으로부터 통로(1c), 연결로(26b), 베어링(12)의 간극 g에 의해 이루어지는 급기통로(33)을 통해서 크랭크실(3)내에 중간압력의 냉매가스를 공급한다.
