Abstract: A rotary compressor (100) includes a closed casing (1), a cylinder (15), a piston (28), a lower bearing member (72), a vane (33), a suction port (20), a discharge port (41), and a partition member (64). The partition member (64) is attached to the lower bearing member (72) so as to form a space enclosed by the partition member (64) and the lower bearing member (72) at a position adjacent to the lower bearing member (72). A portion of an oil stored in the oil reservoir (22) flows into the enclosed space, and thereby an oil retaining portion (53) is formed. The oil retaining portion (53) is located on the same side as the suction port (20) with respect to a reference plane (H 1 ).

Abstract: A compressor (100) with a built-in expander comprises a closed container (1) in which an oil is stored at the bottom, a compressing mechanism (2) or an expanding mechanism (3) disposed at the inside upper part of the closed container (1), an expanding mechanism (3) or a compressing mechanism (2) disposed at the inside lower part of the closed container (1), a shaft (5) for connecting the compressing mechanism (2) to the expanding mechanism (3), and an oil pump (6) for supplying the oil (26) with which the space around the expanding mechanism (3) is filled to the compressing mechanism (2). The compressor (100) is characterized in that the oil pump (6) is disposed between the compressing mechanism (2) and the expanding mechanism (3). Since the oil is supplied to the mechanism positioned in the upper space without passing through the mechanism positioned at the lower space, heat transfer between the expanding mechanism (3) and the compressing mechanism (2) can be reduced.
