Abstract

See full text

A compression part of a rotary compressor includes an intermediate partition plate that is arranged between an upper cylinder and a lower cylinder, an upper vane that sections an upper cylinder chamber formed within the upper cylinder into an upper suction chamber and an upper compression chamber, and a lower vane that sections a lower cylinder chamber formed within the lower cylinder into a lower suction chamber and a lower compression chamber. The intermediate partition plate is formed with an injection hole that injects a liquid refrigerant into the upper compression chamber and the lower compression chamber and an injection passage that supplies the liquid refrigerant to the injection hole. The injection passage is formed along a straight line that does not cross a rotary shaft insertion hole into which a rotary shaft is inserted.
