ROTARY COMPRESSOR

A rotary compressor includes a drive mechanism, a compression mechanism, an introduction path to introduce a fluid into a compression chamber of the compression mechanism, and a backflow suppression mechanism. At least one of a first surface and a second surface of a valve body includes an annular f...

Beschreibung
Zusammenfassung:	A rotary compressor includes a drive mechanism, a compression mechanism, an introduction path to introduce a fluid into a compression chamber of the compression mechanism, and a backflow suppression mechanism. At least one of a first surface and a second surface of a valve body includes an annular first non-contact region that is formed in a predetermined range extending radially inward from an outer edge of the valve body and that does not come into contact with a corresponding valve seat, an annular second non-contact region that is formed in a predetermined range extending radially outward from the hole of the valve body and that does not come into contact with a corresponding valve seat, and a contact region that is formed between the first non-contact region and the second non-contact region and that comes into contact with a corresponding valve seat.
