COMPRESSOR

WIPO Patent Application WO/2021/111546

A1

A compressor according to the present invention is provided with: a compression mechanism part that ejects a refrigerant compressed therein from an ejection port; a sealing container in which the compression mechanism part is accommodated and an ejection chamber in which the refrigerant ejected from the ejection port flows is formed; and an ejection valve mechanism that covers the ejection port from a side of the ejection chamber to be freely openable and closable. The compression mechanism part is provided with a valve seat at a rim of an end on the side of the ejection chamber of the ejection port. The ejection valve mechanism is provided with a reed valve that extends to the ejection port from a fixation spot with the compression mechanism part and contacts the valve seat. The reed valve elastically deforms using the fixation spot as a fixation end due to pressure of the refrigerant ejected from the ejection port. The inside of the compression mechanism part communicates with the ejection chamber. The reed valve is provided with a first plate thickness part including a spot that contacts the valve seat and a second plate thickness part that extends to the fixation spot from the first plate thickness part. The maximum thickness of the first plate thickness part is larger than that of the second plate thickness part.
