Abstract
A rotary compressor () includes a closed casing (), a cylinder (), a piston (), a lower bearing member (), a vane (), a suction port, a discharge port (), and a partition member (). The partition member () is attached to a second principal surface () of the lower bearing member () located on the opposite side to the cylinder () so as to form a refrigerant discharge space () serving as a flow path of a refrigerant discharged from a discharge chamber through the discharge port (). The refrigerant discharge space () is limited so that a region where the refrigerant discharge space () is not present is formed on the same side as the suction port with respect to a first reference plane, and in that region, the second principal surface () of the lower bearing member () is in contact with an oil in an oil reservoir () directly or via the partition member ().
