Abstract

상부측에 회전축을 갖는 전동요소와, 하부측에 이 전동요소의 회전축에 의해서 구동되는 압축요소를 수용한 밀폐형 로터리 압축기의 고출력화 및 C. O. P의 향상을 도모한다.It is intended to improve the output of C. O. P and improve the sealed rotary compressor which accommodates the transmission element which has a rotating shaft in the upper side, and the compression element driven by the rotating shaft of this transmission element in the lower side.

상기한 회전축(4)의 상단에서 편심부까지의 지름(D1)과 상기 호전축의 편심부에서 하단까지의 지름(D2)의 비(比)(D2/D1)을 1미만으로 하고 바람직하게는 토출포트(23A)가 실린더내에 개구하는 포트부분(23B)의 면적을 상기 토출포트(23A)의 전체 단면적에 대하여 50%이상으로 하며, 롤러(19)의 몸통두께를 실린더내에 개구하는 상기의 포트부분(23B)를 폐쇄(seal)하는데 충분한 두께로 한다.The ratio D2 / D1 of the diameter D1 from the upper end to the eccentric part of the rotary shaft 4 and the diameter D2 from the eccentric part to the lower end of the rotary shaft is less than 1, and preferably discharged. The area of the port portion 23B opened by the port 23A in the cylinder is 50% or more with respect to the total cross-sectional area of the discharge port 23A, and the port portion which opens the body thickness of the roller 19 in the cylinder. It is made thick enough to seal 23B.
