Abstract:
A rotary compressor (100) has a sealed container (1), a cylinder (15), a piston (28), a bottom bearing member (7), a vane (33), an intake port (20), a discharge port (41), and a partitioning member (10). The portioning member (10) is attached to the bottom bearing member (7) in such a manner that a refrigerant discharge space (52) is formed as a flow passage for a refrigerant that passes through the discharge port (41) and is discharged from a discharge compartment (26b). A first recessed part (7t) is provided to the bottom bearing member (7) on the same side as the intake port (20), as viewed from a reference plane that includes the center of the vane (33) and the central axis of a cylinder (15) when the vane (33) protrudes to the greatest extent toward the central axis of the cylinder (15). An oil retaining part (53) is formed by a portion of oil that has accumulated in an oil reservoir (22) entering the first recessed part (7t).
