摘要 |
A rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (7), a vane (33), a suction port (20), a discharge port (41), and a partition member (10). The partition member (10) is attached to the lower bearing member (7) so as to form a refrigerant discharge space (52) serving as a flow path of a refrigerant discharged from a discharge chamber (26b) through the discharge port (41). The lower bearing member (7) is provided with a first recess (7t) on the same side as the suction port (20) with respect to a reference plane, the reference plane being a plane including a central axis of the cylinder (15) and a center of the vane (33) when the vane (33) protrudes maximally toward the central axis of the cylinder (15). A portion of oil stored in an oil reservoir (22) flows into the first recess (7t), and thereby an oil retaining portion (53) is formed. |
