Document Type and Number:

WIPO Patent Application WO/2013/094114

Kind Code:

A1

Abstract:

A rotary compressor (100) having a sealed container (1), a cylinder (15), a piston (28), a lower bearing member (7), a vane (33), a suction port, a discharge port (41), and a partition member (10). The partition member (10) is attached to a second main surface (7a) of the lower bearing member (7) on the side opposite the cylinder (15) so as to form a refrigerant discharge space (52) as a flow path for refrigerant discharged from a discharge chamber through the discharge port (41). The refrigerant discharge space (52) is restricted such that, when viewed from a first reference plane, a region wherein the refrigerant discharge space (52) does not exist is formed on the same side as the suction port, and at that region the second main surface (7a) of the lower bearing member (7) makes contact with oil in an oil reservoir (22), either directly or via the partition member (10).
