Abstract

로타리밸브의 테이퍼외주면과 그것을 수용하는 수용실의 테이퍼내주면과의 회전마찰을 제어해서 압축기의 구동에 필요한 동력손실을 경감한다.Rotational friction between the tapered outer circumferential surface of the rotary valve and the tapered inner circumferential surface of the receiving chamber is controlled to reduce the power loss required to drive the compressor.

피스톤(15)에 의해 실린더(13)내에 구획된 작동실(Ra)에 냉매가스를 도입하기 위한 흡입통로(29)를 로타리밸브(27)내에 형성한다.A suction passage 29 for introducing refrigerant gas into the operating chamber Ra partitioned in the cylinder 13 by the piston 15 is formed in the rotary valve 27.

이 밸브(27)을 수용하는 수용실(1a)의 테이퍼내주면(S)에는 흡입행정중의 작동실(Ra)와 전기한 로타리밸브(27)의 흡입통로(29)의 출구(29b)등을 연결하는 연결로(1b)를 형성한다. 전기한 연결로(1b)의 실린더(13)쪽 출구(1c)의 위치를 전기한 피스톤(15)가 상사점으로 이동하기 이전에 그 피스톤(15)의 외주면(15a)에 의해 폐쇄된 위치에 설정한다. 더우기, 테이퍼외주면(27c)에는 전기한 연결로(1b)내가 피스톤(15)의 외주면(15a) 및 테이퍼외주면(27c)에 의해 밀폐공간이 되어 있는 상태에서 그 공간의 냉매가스를 압축도중의 작동실(Ra)와 연결하는 다른 연결로(1b)내로 안내하는 바이패스통로(27d)를 형성한다.In the tapered inner peripheral surface S of the storage chamber 1a which accommodates this valve 27, the operation chamber Ra of a suction stroke, the outlet 29b of the suction passage 29 of the rotary valve 27, etc. which were mentioned above are provided. The connection path 1b which connects is formed. The position of the outlet 1c on the cylinder 13 side of the connection path 1b described above is in a position closed by the outer peripheral surface 15a of the piston 15 before the piston 15 moves to the top dead center. Set it. Furthermore, the taper outer circumferential surface 27c is operated during the compression of refrigerant gas in the space in the state in which the connection path 1b that has been electrically sealed is formed by the outer circumferential surface 15a of the piston 15 and the tapered outer circumferential surface 27c. A bypass passage 27d is guided into another connection passage 1b that connects to the yarn Ra.
