Abstract:
A compression mechanism part of this rotary compressor is provided with: a rotating shaft having a main shaft part and an eccentric shaft part; a cylinder having a cylinder chamber; a rotating piston that eccentrically rotates inside the cylinder chamber of the cylinder; and two end plates arranged on both end surfaces in the axial direction of the rotating shaft in the cylinder. Further, the compression mechanism part operates together with eccentric rotation of the rotating piston and is provided with a seal plate that seals a portion of an injection port formed on one of the two end plates, the portion positioned inside of an inner peripheral surface of the rotating piston. The seal plate is formed separately from the rotating piston, relatively freely rotatable with respect to the rotating piston, and has a penetration hole through which the main shaft part of the rotating shaft passes. The penetration hole is open to an outside in the radial direction.
