成される。The above purpose is to provide a cylinder provided with a discharge valve chamber composed of a curved surface part and a flat part, a cylinder chamber provided in the cylinder, and a discharge boat provided in the discharge valve chamber so as to communicate both chambers. , a hermetic rotary compressor comprising a discharge valve whose one end opens and closes the discharge boat and whose other end is fixed to the discharge valve chamber along the curved surface, the other end of the discharge valve is connected to the discharge valve chamber. This is achieved by pressing the flat part.
即ち、吐出弁の他端は吐出弁室の平面部を押圧した状態
で取付けられるので、吐出弁は吐出弁室の内壁に密着固
定する。それによって、吐出弁の誤動作がないので圧縮
機の容積効率向上を図ることができる。That is, since the other end of the discharge valve is attached while pressing against the flat surface of the discharge valve chamber, the discharge valve is tightly fixed to the inner wall of the discharge valve chamber. Thereby, there is no malfunction of the discharge valve, so it is possible to improve the volumetric efficiency of the compressor.
以下、本発明の一実施例を第１図、第２図により説明す
